The remote start signal will also wake up the control from sleep mode. The control can incorporate a time delay start and stop. Remote and local emergency stop - The control accepts a ground signal from a local (genset mounted) or remote (facility mounted) emergency stop switch to cause the generator set to immediately shut down. The generator set is prevented from running or cranking with the switch engaged. If in sleep mode, activation of either emergency stop switch will wakeup the control. Sleep mode - The control includes a configurable low current draw state to minimize starting battery current draw when the genset is not operating. The control can also be configured to go into a low current state while in auto for prime applications or applications without a battery charger. Engine starting - The control system supports automatic engine starting. Primary and backup start disconnects are achieved by one of two methods: magnetic pickup or main alternator output frequency. The control also supports configurable glow plug control when applicable. Cycle cranking - Is configurable for the number of starting cycles (1 to 7) and duration of crank and rest periods. Control includes starter protection algorithms to prevent the operator from specifying a starting sequence that might be damaging. Time delay start and stop (cooldown) - Configurable for time delay of seconds prior to starting after receiving a remote start signal and for time delay of seconds prior to shut down after signal to stop in normal operation modes. Default for both time delay periods is 0 seconds. Alternator control The control includes an integrated three phase line-toline sensing voltage regulation system that is compatible with shunt or PMG excitation systems. The voltage regulation system is a three phase full wave rectified and has an FET output for good motor starting capability. Major system features include: Digital output voltage regulation - Capable of regulating output voltage to within +/-1.0% for any loads between no load and full load. Voltage drift will not exceed +/- 1.5% for a 40 ºC (104 ºF) change in temperature in an eight hour period. On engine starting or sudden load acceptance, voltage is controlled to a maximum of 5% overshoot over nominal level. The automatic voltage regulator feature can be disabled to allow the use of an external voltage regulator. Droop voltage regulation - Control can be adjusted to droop from 0-10% from no load to full load. Torque-matched V/Hz overload control - The voltage roll-off set point and rate of decay (i.e. the slope of the V/Hz curve) is adjustable in the control. Fault current regulation - PowerCommand will regulate the output current on any phase to a maximum of three times rated current under fault conditions for both single phase and three phase faults. In conjunction with a permanent magnet generator, it will provide three times rated current on all phases for motor starting and short circuit coordination purpose. Protective functions On operation of a protective function the control will indicate a fault by illuminating the appropriate status LED on the HMI, as well as display the fault code and fault description on the LCD. The nature of the fault and time of occurrence are logged in the control. The service manual and InPower service tool provide service keys and procedures based on the service codes provided. Protective functions include: Battle short mode When enabled and the battle short switch is active, the control will allow some shutdown faults to be bypassed. If a bypassed shutdown fault occurs, the fault code and Our energy working for you Cummins Power Generation Inc.All rights reservedspecifications subject to change without noticecummins Power Generation and Cummins are registered trademarks of Cummins Inc.

18 description will still be annunciated, but the genset will not shutdown. This will be followed by a fail to shutdown fault. Emergency stop shutdowns and others that are critical for proper operation are not bypassed. Please refer to the Control Application Guide or Manual for list of these faults. Derate The Derate function reduces output power of the genset in response to a fault condition. If a derate command occurs while operating on an isolated bus, the control will issue commands to reduce the load on the genset via contact closures or Modbus. Configurable alarm and status inputs The control accepts up to four alarm or status inputs (configurable contact closed to ground or open) to indicate a configurable (customer-specified) condition. The control is programmable for warning, shutdown or status indication and for labeling the input. Emergency stop Annunciated whenever either emergency stop signal is received from external switch. Full authority electronic engine protection Engine fault detection is handled inside the engine ECM. Fault information is communicated via the SAE-J1939 data link for annunciation in the HMI. General engine protection Low and high battery voltage warning - Indicates status of battery charging system (failure) by continuously monitoring battery voltage. Weak battery warning - The control system will test the battery each time the generator set is signaled to start and indicate a warning if the battery indicates impending failure. Fail to start (overcrank) shutdown - The control system will indicate a fault if the generator set fails to start by the completion of the engine crack sequence. Fail to crank shutdown - Control has signaled starter to crank engine but engine does not rotate. Cranking lockout - The control will not allow the starter to attempt to engage or to crank the engine when the engine is rotating. Alternator protection AmpSentry Protective relay - A UL Listed comprehensive monitoring and control system integral to the PowerCommand Control System that guards the electrical integrity of the alternator and power system by providing protection against a wide array of fault conditions in the generator set or in the load. It also provides single and three phase fault current regulation so that downstream protective devices have the maximum current available to quickly clear fault conditions without subjecting the alternator to potentially catastrophic failure conditions. See document R1053 for a full size time over current curve. High AC voltage shutdown (59) - Output voltage on any phase exceeds preset values. Time to trip is inversely proportional to amount above threshold. Values adjustable from % of nominal voltage, with time delay adjustable from seconds. Default value is 110% for 10 seconds. Low AC voltage shutdown (27) - Voltage on any phase has dropped below a preset value. Adjustable over a range of 50-95% of reference voltage, time delay 2-20 seconds. Default value is 85% for 10 seconds. Function tracks reference voltage. Control does not nuisance trip when voltage varies due to the control directing voltage to drop, such as during a V/Hz roll-off during synchronizing. Under frequency shutdown (81 u) - Generator set output frequency cannot be maintained. Settings are adjustable from 2-10 Hz below reference governor set point, for a 5-20 second time delay. Default: 6 Hz, 10 seconds. Under frequency protection is disabled when excitation is switched off, such as when engine is operating in idle speed mode. Over frequency shutdown/warning (81o) - Generator set is operating at a potentially damaging frequency level. Settings are adjustable from 2-10 Hz above nominal governor set point for a 1-20 second time delay. Default: 6 Hz, 20 seconds, disabled.

48 SENS EnerGenius Technical Manual 4. NEUTRAL CONNECTION The grounded circuit conductor (neutral) should be connected to the terminal marked N on the input terminal block, TB1. 5. WIRE RATINGS A. All conductors should be rated for use at 90º C or higher. B. All input and output conductor sizes should be coordinated with the fault protection devices: 10A on AC input (14 AWG, 2.5 mm 2 typical), 30A on DC output (10 AWG, 6.0 mm 2 typical). 1 A on Alarm terminal block (20 AWG, 0.5 mm 2 typical). C. Before installation, ensure adequate battery to charger wire gauge. Wire gauge that is too small may activate the open battery detector and the charger will shut down. The maximum allowed resistance seen by the charger is found in TABLE 1. These figures already include an allowance for charger variations (they are 80% of the typical trip-point) and are for the complete circuit: total of battery leads, battery's internal resistance, and any external equipment. The total resistance seen by the charger must not exceed the following values: TABLE 1 12V 24V Maximum Resistance 58m 116m D. To determine the appropriate cable and length, please refer to the following table: Wire Size Resistance per Foot TABLE 2 Maximum Charger to Battery Distance (Ft.) Recommended Charger to Battery Distance (Ft.) AWG mm 2 m/ft. 12V 24V 12V 24V The above lengths consider the resistance of the battery and cables only and do not take into account any additional interconnects. The above lengths are for operation at 25C. For high temperature installations (40C) reduce lengths by 10%. In the case of high resistance in the cables to the battery the charger may cycle between AC Fail and Battery Fault LEDs (approximately every 10 seconds). Cable runs exceeding the proper length for the cable gauge used most often cause this problem. The appropriate solution is to change the cable gauge to properly correspond with the necessary cable length (see TABLE 2). In some cases where the resistance is not too far above maximum, the charger may recover after some time (approximately 10 minutes) and start charging the batteries. If it is not possible to decrease the system resistance the Battery Fault feature can be disabled. Please contact SENS at for further information. E. Refer to local electrical codes for additional requirements. F. See Section 10 for Terminal Block wire ranges. 6. FUSE RATINGS A.

49 PowerCommand Annunciator Discrete Input or PCCNet Description The Universal Annunciator Module provides visual and audible indication of up to 20 separate alarm or status conditions, based on discrete (relay) inputs or network inputs. Each LED can be controlled by either a discrete wire input or by a signal on the PCCNet network sent from an external device, such as a PCC1301 or PCC2100 (version 2.4 or later) control. In addition to the LEDs, the annunciator can control four custom relays based on signals received over the PCCNet. When one of the annunciator s discrete inputs is activated, the annunciator will broadcast that information over the network. By taking advantage of the network, discrete inputs and custom relays, the annunciator can be used as expanded I/O for a genset controller. Easily installed in a location to give immediate notification of an alarm or warning status. Designed to give operating/monitoring personnel quick-glance status information. The module directly senses battery voltage to provide green/yellow/red alarm and status information for that parameter. Genset controller complies with NFPA level two requirements when used with the display but without the annunciator panel. When used with the annunciator it meets NFPA level one requirements (emergency and standby power systems). The annunciator module can also be used for monitoring of transfer switch or other equipment status. Features Visual and audible warnings of up to 20 separate alarm or status conditions. LEDs can be controlled either via PCCNet or discrete input. Status of discrete inputs is broadcast on network. Four custom relays can be controlled over the PCCNet network. Configurable LED color (red, yellow or green) and selectable horn operation allows maximum flexibility. Standard NFPA 110 label, field configurable for other alarm status and conditions. Each audible alarm is annunciated, regardless of the number of existing alarm conditions displayed. Sealed membrane panel design provides environmental protection for internal components and is easy to clean. Configurable for negative (ground) input or positive input. Integral DC voltage sensing. Flush or surface mount provisions. UL Listed and labeled; CSA certified; CE marked Cummins Power Generation Inc. All rights reserved.

57 OTPC transfer switch open and closed transition Amp Description OTPC transfer switches are designed for operation and switching of electrical loads between primary power and standby generator sets. They are suitable for use in emergency, legally required and optional standby applications. The switch monitors both power sources, signals generator set startup, automatically transfers power, and returns the load to the primary power source when the utility returns and stabilizes. OTPC transfer switches are available with closed transition transfer. By briefly connecting the two sources (for 100 msec or less), the transfer from the alternate source back to the normal source occurs without interruption in the power supply to loads. NEC All switches are UL 1008 Listed with UL Type Rated cabinets and UL Listed CU-AL terminals. All switches are certified to CSA 282 Emergency Electrical Power Supply for Buildings, up to 600 VAC. Suitable for use in emergency, legally required and standby applications per NEC 700, 701 and 702. All switches comply with NFPA 70, 99 and 110 (Level 1). All switches comply with NEMA ICS 10. All switches comply with IEEE 446 Recommended Practice for Emergency and Standby Power Systems. This transfer switch is designed and manufactured in facilities certified to ISO9001. Features PowerCommand control - A fully featured microprocessor-based control with digital display. Controls allow operator to enter settings and make adjustments to software-enabled features easily and accurately. Accommodates up to eight event schedules. Programmed transition Open transition timing can be adjusted to completely disconnect the load from both sources for a programmed time period, as recommended by NEMA MG-1 for transfer of inductive loads. Advanced transfer switch mechanism Unique bidirectional linear actuator provides smooth, continuous transfer switch action during automatic operation. Robust control system design - Optically isolated logic inputs and isolation transformers for AC power inputs provide high-voltage surge protection.

58 Transfer switch mechanism Specifications Voltage rating Arc interruption Neutral bar Auxiliary contacts Our energy working for you. Transfer switch mechanism is electrically operated and mechanically held in the Source 1 and Source 2 positions. The transfer switch incorporates electrical and mechanical interlocks to prevent inadvertent interconnection of the sources. Independent break-before-make action is used for both 3-pole and 4-pole/ switched neutral switches. This design allows use of sync check operation when required, or control of the operating speed of the transfer switch for proper transfer of motor and rectifier-based loads (programmed transition feature). True 4-pole switching allows for proper ground (earth) fault sensing and consistent, reliable operation for the life of the transfer switch. The neutral poles of the transfer switch have the same ratings as the phase poles and are operated by a common crossbar mechanism, eliminating the possibility of incorrect neutral operation at any point in the operating cycle, or due to failure of a neutral operator. High pressure silver alloy contacts resist burning and pitting. Separate arcing surfaces further protect the main contacts. Contact wear is reduced by multiple leaf arc chutes that cool and quench the arcs. Barriers separate the phases to prevent interphase flashover. A transparent protective cover allows visual inspection while inhibiting inadvertent contact with energized components. Switch mechanism, including contact assemblies, is third party certified to verify suitability for applications requiring high endurance switching capability for the life of the transfer switch. Withstand and closing ratings are validated using the same set of contacts, further demonstrating the robust nature of the design. 600 VAC, 50 or 60 Hz. Multiple leaf arc chutes provide dependable arc interruption. Operating temperature -40 F (-40 C) to 140 F (60 C) Storage temperature -40 F (-40 C) to 140 F (60 C) Humidity Altitude Surge withstand ratings Total transfer time (sourceto-source) Manual operation handles A full current-rated neutral bar with lugs is standard on enclosed 3-pole transfer switches. Two isolated contacts (one for each source) indicating switch position are provided for customer use. Contacts are normally open, and close to indicate connection to the source. Wired to terminal block for easy access. Rated at 10 amps continuous and 250 VAC maximum. UL recognized, and CSA-certified. Up to 95% relative, non-condensing Up to 10,000 ft (3,000 m) without derating Voltage surge performance and testing in compliance with the requirements of IEEE C62.41 (Category B3) and IEEE C Will not exceed 6 cycles at 60 Hz with normal voltage applied to the actuator and without programmed transition enabled. Transfer switches rated through 1000 amps are equipped with permanently attached operating handles and quick-break, quick-make contact mechanisms suitable for manual operation. Transfer switches over 1000 amps are equipped with manual operators. All switches must be de-energized before manual operation is attempted. Transition modes Open transition/programmed: Controls the time required for the device to switch from source to source, so that the load-generated voltages decay to a safe level before connecting to an energized source. Recommended by NEMA MG- 1 to prevent nuisance-tripping breakers and load damage. Adjustable 0-60 seconds, default 0 seconds. Programmed transition is standard on amp switches, and optional on amps. Open transition/in-phase: Initiates open transition transfer when in-phase monitor senses both sources are in phase. Operates in a break-before-make sequence. Includes ability to enable programmed transition as a back-up. If sources are not in phase within 120 seconds, switches from amps will transfer using programmed transition (not available on open transition switches over 1200 amps). Closed transition: Used in applications where loads are sensitive to the momentary power interruption that occurs when performing open transition between sources. Closed transition is accomplished by briefly (<100 msec) paralleling two good sources to eliminate the momentary break in the power supply. Closed transition is only available as an option on OTPC models from amps. Genset-to-genset: Either genset can be designated as the lead genset. If the lead genset goes down or is taken offline, the transfer switch starts the second genset and transfers the load. The control can be programmed to alternate between the two gensets at a set interval up to 336 hours (2 weeks) Cummins Power Generation Inc. All rights reserved.

60 Time-delay functions Engine start: Prevents nuisance genset starts due to momentary power system variation or loss. Not included in utility-to-utility systems. Transfer normal to emergency: Allows genset to stabilize before application of load. Prevents power interruption if normal source variation or loss is momentary. Allows staggered transfer of loads in multiple transfer switch systems. For genset-to-genset applications, delays transfer of load from lead to secondary generator. Re-transfer emergency to normal: Allows the utility to stabilize before re-transfer of load. Prevents needless power interruption if return of normal source is momentary. Allows staggered transfer of loads in multiple transfer switch systems. For genset-to-genset applications, delays re-transfer of load from secondary back to lead generator. Engine stop: Maintains availability of the genset for immediate reconnection if the normal source fails shortly after retransfer. Allows gradual genset cool down by running unloaded. Not included in utility-to-utility systems. Elevator pre-transfer signal: Requires optional relay signal module (M023). Signals elevator system that transfer is pending and delays transfer for pre-set interval of 0-60 seconds to prevent a power interruption during elevator operation. User interfaces Basic interface panel LED indicators provide at-a-glance source and transfer switch status for quick summary of system conditions. Test and override buttons allow delays to be bypassed for rapid system checkout. Digital display (M018) The digital display provides a convenient method for monitoring load power conditions, adjusting transfer switch parameters, monitoring PowerCommand network status or reviewing transfer switch events. Password protection limits access to adjustments to authorized personnel. The digital display is optional with the PowerCommand Level 1 control and comes standard with the Level 2 control. User interface options Front panel security key (M017) Locks front panel to prohibit access to digital control settings. Prevents unauthorized activation of transfer or test functions. Bar graph meter display (D009) An LED bar graph display provides an easy-to-read indicator of the level of power being supplied to the load. Information displayed includes: 3-phase voltage and current, frequency, power factor, and kilowatts. Green, amber, and red LEDs provide at-a-glance indication of system acceptability. Available as an option with the Level 2 PowerCommand microprocessor control. Control options Relay signal module (M023) Provides relay output contacts for sending information to the building monitoring and control system. Relay outputs include: Source 1 connected/available, Source 2 connected/available, not in auto, test/exercise active, failed to disconnect, failed to synchronize, failed to transfer/re-transfer, and elevator control pre-transfer signal. Loadshed (M007) Removes the load from the emergency power source by driving the transfer switch to the neutral position when signaled remotely. Transfers load back to the emergency source when the signal contacts open. Immediately retransfers back to the primary source when available. Available for utility-to-genset applications only. PowerCommand network interface (M031) Provides connection to the PowerCommand network. LonWorks compatible for integration with building monitoring and control system. Load power and load current monitoring (M022) Measures load phase and neutral current, power factor, real power (kw) and apparent power (kva). Warns of excessive neutral current resulting from unbalanced or nonlinear loads. Minimum current level detection is 3% Cummins Power Generation Inc. All rights reserved.

108 SENS EnerGenius Technical Manual 4. NEUTRAL CONNECTION The grounded circuit conductor (neutral) should be connected to the terminal marked N on the input terminal block, TB1. 5. WIRE RATINGS A. All conductors should be rated for use at 90º C or higher. B. All input and output conductor sizes should be coordinated with the fault protection devices: 10A on AC input (14 AWG, 2.5 mm 2 typical), 30A on DC output (10 AWG, 6.0 mm 2 typical). 1 A on Alarm terminal block (20 AWG, 0.5 mm 2 typical). C. Before installation, ensure adequate battery to charger wire gauge. Wire gauge that is too small may activate the open battery detector and the charger will shut down. The maximum allowed resistance seen by the charger is found in TABLE 1. These figures already include an allowance for charger variations (they are 80% of the typical trip-point) and are for the complete circuit: total of battery leads, battery's internal resistance, and any external equipment. The total resistance seen by the charger must not exceed the following values: TABLE 1 12V 24V Maximum Resistance 58m 116m D. To determine the appropriate cable and length, please refer to the following table: Wire Size Resistance per Foot TABLE 2 Maximum Charger to Battery Distance (Ft.) Recommended Charger to Battery Distance (Ft.) AWG mm 2 m/ft. 12V 24V 12V 24V The above lengths consider the resistance of the battery and cables only and do not take into account any additional interconnects. The above lengths are for operation at 25C. For high temperature installations (40C) reduce lengths by 10%. In the case of high resistance in the cables to the battery the charger may cycle between AC Fail and Battery Fault LEDs (approximately every 10 seconds). Cable runs exceeding the proper length for the cable gauge used most often cause this problem. The appropriate solution is to change the cable gauge to properly correspond with the necessary cable length (see TABLE 2). In some cases where the resistance is not too far above maximum, the charger may recover after some time (approximately 10 minutes) and start charging the batteries. If it is not possible to decrease the system resistance the Battery Fault feature can be disabled. Please contact SENS at for further information. E. Refer to local electrical codes for additional requirements. F. See Section 10 for Terminal Block wire ranges. 6. FUSE RATINGS A.

109 PowerCommand Annunciator Discrete Input or PCCNet Description The Universal Annunciator Module provides visual and audible indication of up to 20 separate alarm or status conditions, based on discrete (relay) inputs or network inputs. Each LED can be controlled by either a discrete wire input or by a signal on the PCCNet network sent from an external device, such as a PCC1301 or PCC2100 (version 2.4 or later) control. In addition to the LEDs, the annunciator can control four custom relays based on signals received over the PCCNet. When one of the annunciator s discrete inputs is activated, the annunciator will broadcast that information over the network. By taking advantage of the network, discrete inputs and custom relays, the annunciator can be used as expanded I/O for a genset controller. Easily installed in a location to give immediate notification of an alarm or warning status. Designed to give operating/monitoring personnel quick-glance status information. The module directly senses battery voltage to provide green/yellow/red alarm and status information for that parameter. Genset controller complies with NFPA level two requirements when used with the display but without the annunciator panel. When used with the annunciator it meets NFPA level one requirements (emergency and standby power systems). The annunciator module can also be used for monitoring of transfer switch or other equipment status. Features Visual and audible warnings of up to 20 separate alarm or status conditions. LEDs can be controlled either via PCCNet or discrete input. Status of discrete inputs is broadcast on network. Four custom relays can be controlled over the PCCNet network. Configurable LED color (red, yellow or green) and selectable horn operation allows maximum flexibility. Standard NFPA 110 label, field configurable for other alarm status and conditions. Each audible alarm is annunciated, regardless of the number of existing alarm conditions displayed. Sealed membrane panel design provides environmental protection for internal components and is easy to clean. Configurable for negative (ground) input or positive input. Integral DC voltage sensing. Flush or surface mount provisions. UL Listed and labeled; CSA certified; CE marked Cummins Power Generation Inc. All rights reserved.

116 Transfer switch mechanism Specifications Voltage rating Arc interruption Neutral bar Auxiliary contacts Our energy working for you. Transfer switch mechanism is electrically operated and mechanically held in the Source 1 and Source 2 positions. The transfer switch incorporates electrical and mechanical interlocks to prevent inadvertent interconnection of the sources. Independent break-before-make action is used for both 3-pole and 4-pole/ switched neutral switches. This design allows use of sync check operation when required, or control of the operating speed of the transfer switch for proper transfer of motor and rectifier-based loads (programmed transition feature). True 4-pole switching allows for proper ground (earth) fault sensing and consistent, reliable operation for the life of the transfer switch. The neutral poles of the transfer switch have the same ratings as the phase poles and are operated by a common crossbar mechanism, eliminating the possibility of incorrect neutral operation at any point in the operating cycle, or due to failure of a neutral operator. High pressure silver alloy contacts resist burning and pitting. Separate arcing surfaces further protect the main contacts. Contact wear is reduced by multiple leaf arc chutes that cool and quench the arcs. Barriers separate the phases to prevent interphase flashover. A transparent protective cover allows visual inspection while inhibiting inadvertent contact with energized components. Switch mechanism, including contact assemblies, is third party certified to verify suitability for applications requiring high endurance switching capability for the life of the transfer switch. Withstand and closing ratings are validated using the same set of contacts, further demonstrating the robust nature of the design. 600 VAC, 50 or 60 Hz. Multiple leaf arc chutes provide dependable arc interruption. Operating temperature -40 F (-40 C) to 140 F (60 C) Storage temperature -40 F (-40 C) to 140 F (60 C) Humidity Altitude Surge withstand ratings Total transfer time (sourceto-source) Manual operation handles Transition modes A full current-rated neutral bar with lugs is standard on enclosed 3-pole transfer switches. Two isolated contacts (one for each source) indicating switch position are provided for customer use. Contacts are normally open, and close to indicate connection to the source. Wired to terminal block for easy access. Rated at 10 amps continuous and 250 VAC maximum. UL recognized, and CSA-certified. Up to 95% relative, non-condensing Up to 10,000 ft (3,000 m) without derating Voltage surge performance and testing in compliance with the requirements of IEEE C62.41 (Category B3) and IEEE C Will not exceed 6 cycles at 60 Hz with normal voltage applied to the actuator and without programmed transition enabled. Transfer switches rated through 1000 amps are equipped with permanently attached operating handles and quick-break, quick-make contact mechanisms suitable for manual operation. Transfer switches over 1000 amps are equipped with manual operators. All switches must be de-energized before manual operation is attempted. Open transition/programmed: Controls the time required for the device to switch from source to source, so that the load-generated voltages decay to a safe level before connecting to an energized source. Recommended by NEMA MG- 1 to prevent nuisance-tripping breakers and load damage. Adjustable 0-60 seconds, default 0 seconds. Programmed transition is standard on amp switches, and optional on amps. Open transition/in-phase: Initiates open transition transfer when in-phase monitor senses both sources are in phase. Operates in a break-before-make sequence. Includes ability to enable programmed transition as a back-up. If sources are not in phase within 120 seconds, switches from amps will transfer using programmed transition (not available on open transition switches over 1200 amps). Closed transition: Used in applications where loads are sensitive to the momentary power interruption that occurs when performing open transition between sources. Closed transition is accomplished by briefly (<100 msec) paralleling two good sources to eliminate the momentary break in the power supply. Closed transition is only available as an option on OTPC models from amps. Genset-to-genset: Either genset can be designated as the lead genset. If the lead genset goes down or is taken offline, the transfer switch starts the second genset and transfers the load. The control can be programmed to alternate between the two gensets at a set interval up to 336 hours (2 weeks) Cummins Power Generation Inc. All rights reserved.

142 Operator panel The operator panel provides the user with a complete package of easy to view and use information. It includes an enhanced graphical operator panel that allows the user to view up to 9 lines of information, as well as graphical displays of system data. Connections to the operator panel are sealed, locking plug interfaces for reliable, vibration-resistant interconnection to the generator set wiring harness. Control switches and functions Operator adjustments - The control includes provisions for many set up and adjustment functions via raise/lower switches on the operator panel. Functions that can be adjusted by the operator include: - Time delay start (0-300 seconds) - Time delay stop (0-600 seconds) - Alternator voltage (+5%) - Alternator frequency (+3 Hz) The operator panel can be configured to require an access code prior to adjusting these values. A second access code is used to protect the control from unauthorized service level adjustments. Voltage and frequency adjustments are disabled during operation in parallel with a system bus to prevent inadvertent misadjustment of the paralleling load sharing functions. Analog AC metering panel Off/manual/auto mode control switch - The not in auto lamp will flash when the control is in the manual or off mode. In the auto mode, the generator set can be started using the exercise push-button or with a start signal from a remote device, such as automatic transfer switches. Manual run/stop control switch and indicating LED - When the mode control switch is in the manual position and the manual run/stop switch is pressed, the generator set will start, bypassing all time delay starts. (Time delay idle can also be bypassed with another control action.) If the generator set is running in the manual mode, pressing the run/stop switch will cause the generator set to shut down. An LED (light emitting diode) lamp adjacent to the switch will light to indicate the generator set is in manual mode. Exercise control switch and indicating LED - When the mode control switch is in the auto position the exercise control switch is used to complete a pre-programmed exercise sequence. All exercise functions are disabled when an emergency start command is received by the control. An LED lamp adjacent to the switch will light to indicate the generator set is in exercise mode. Panel lamp/lamp test control switch. Fault acknowledge/reset switch - The control includes a fault acknowledge function to allow the operator to reset the fault condition. If the fault condition is not corrected, the fault will reappear, but will not be logged as a separate event. Multiple faults can be logged and displayed at one time. Emergency stop control switch.

S-1444h (4/08) Page 2 of 10 The PowerCommand control is equipped with an analog AC metering panel that simultaneously displays 3-phase line-to-line AC volts and current, kw, power factor and frequency. The meter panel is composed of a series of LEDs configured in bar graphs for each function. The LEDs are color coded with green indicating normal range values, amber for warning levels and red for shutdown conditions. Scales for each function are in % of nominal rated values. Graphical display panel The PowerCommand control is provided with a graphical display capable of displaying up to 9 lines of data with approximately 27 characters per line. The graphical display is accompanied by a set of six tactile-feel membrane switches that are used by the operator to navigate through control menus and to make control adjustments. Display is configurable for multiple languages. It is configurable for units of measurement. The display incorporates three levels of operation and adjustability. All data on the control can be viewed by

143 scrolling through screens with the navigation keys. The top three lines of the display are allocated to mode and status messages that continuously display the operating mode of the control system, as well as any faults or warning conditions that may be present on the controller. If more than one fault or warning message is present, the messages will scroll to allow the operator to view all active messages in the system. Screen-saver mode - The operator panel can be programmed to automatically switch off to reduce battery voltage drain when the control is not being used and the generator set is not running. Depressing any button on the operator panel, new fault conditions or receipt of a remote signal at the control will wake up the control. Generator set data Generator set hardware data - Generator set rating in kva, complete generator set model number and serial number, engine model and serial number and alternator model and serial number. The control also displays the part number of the control and the software version present in the control. Data logs - Number of start attempts and number of start attempts since reset. Number of times generator set has run and number of times since reset. Duration of generator set running time and duration of running time since last reset. Generator set kwh produced and kwh produced since last reset. Adjustment history - Record of adjustment and setting changes made on the control, identifies whether adjustment was made via the operator panel or with a service tool. If a service tool is used, the control provides a record of the serial number of the tool used. This information is read with InPower. Fault history - Record of the most recent fault conditions with time stamp, along with the number of times each fault has occurred. At least 20 events are stored in the control memory. Load profile data - Data indicating the total operating hours at percent of load in 10% increments and since reset. Generator set AC data Generator set output frequency, voltage and current - All phases (line-to-line and line-to-neutral for voltage. Accuracy 1%. Generator set power output - PowerCommand displays generator set kw and kva output (average phase, individual phase and direction of flow) and power factor with leading/lagging indication. Accuracy 5%. Generator set kwh energy output - Total kwh produced and total produced since last reset with time stamp of time of last reset.

S-1444h (4/08) Page 3 of 10 Digital synchroscope - Bus voltage and frequency, generator set bus voltage and frequency, the phase angle displacement and a signal indicating ready to close. A breaker control switch is included on this panel for convenient operation of the equipment without switching between viewing screens. Engine data Basic engine data - Engine starting battery voltage, engine lube oil pressure and engine coolant temperature. Engine service data - Varies with engine used, but typically includes: Engine coolant pressure, engine fuel rail temperature and pressure, engine fuel input and output temperature, intake manifold temperature and pressure, ambient air pressure, crankcase blowby flow and aftercooler inlet coolant temperature. Engine fuel consumption - The fuel consumed by the engine is calculated by the control based on fuel flow into the engine and returned by the engine, and the temperature of the two flow streams. Accuracy is + 5% over 500 hours of operation. Data provided includes overall average fuel consumed and consumption since reset. This information is read with InPower. Engine exhaust temperature (optional). Power transfer control data (optional) Utility (mains) source data - Displays line-to-line and line-to-neutral voltage of utility (mains) source, frequency and estimated amps, and kw and kva supplied by utility (mains) source (optional when power transfer control is used). System status information - Provides graphical system status display showing availability of sources and positions of each contactor. System control - Allows operator to view status of system and manually control operation of the system. Provides manual adjustment capability for time delay start, stop, transfer and retransfer, as well as time delays for program transition (when used) and power transfer overlap time. Internal control functions General functions System control voltage - The control operates on 24 VDC from the generator set starting batteries. Control functions are fully operational over a voltage range of 8 VDC to 36 VDC. Emergency start mode - PowerCommand accepts a ground signal from remote devices or a network signal to automatically start the generator set and immediately accelerate to rated speed and voltage. PowerCommand includes a smart starting system that is designed to quickly start the engine, minimize black smoke, minimize voltage and frequency overshoot, and

144 oscillations on starting. The control system does this by careful simultaneous control of the engine fuel system and alternator excitation system. Non-emergency start mode - The control is provided with a separate remote start input or a network signal to start the generator set via the programmable idle control. Using the non-emergency mode, the generator set takes longer to start, but there is less wear on the engine. In this start mode, the generator set will start, operate at idle speed for a predefined time period or until the engine reaches operating temperature (whichever time is shorter), and then ramp to rated speed and voltage. Time delay is adjustable from seconds and default is 10 seconds. The control also monitors and records the source of start signals, when that information is available. The control automatically exits idle mode if an emergency remote start signal is received at the control. Data logging - The control maintains a record of manual control operations, warning and shutdown conditions and other events. It uses the control on time as the timestamp means when a real time clock is not included with the control. The control also stores critical engine and alternator data before and after a fault occurs, for use by InPower and the technician in evaluating the root causes for the fault condition. Fault simulation mode - PowerCommand, in conjunction with InPower software, will accept commands to allow a technician to verify the proper operation of critical protective functions of the control by simulating failure modes or by forcing the control to operate outside of its normal operating ranges. InPower also provides a complete list of faults and settings for the protective functions of the specific generator set it is communicating with. Built in test - The control system automatically tests itself, and all the sensors, actuators and harnesses in the control system, on a startup signal. The test can also be initiated from InPower and can be accomplished either locally to the generator set or remotely. Engine control Engine starting - The control operates a factorysupplied fuel valve that enables engine starting. Cycle cranking - Configurable for number of starting cycles (1 to 7) and duration of crank and rest periods. Control includes starter protection algorithms to prevent the operator from specifying a starting sequence that might be damaging. Default setting is for (3) start cycles composed of 15 seconds of cranking and 15 seconds of rest. Programmable idle speed control - In this mode the generator set would start and run to idle speed. It would operate at that speed for a programmed time period, then ramp to rated speed. When the control gets a signal to stop, it will ramp to idle, operate for the programmed period at idle and then shut down.

Other company, product, or service names may be trademarks or service marks of others. S-1444h (4/08) Page 4 of 10 engine protective functions are adjusted for the lower engine speed and alternator function is disabled. Time delay start and stop (cool down) - Configurable for time delay of seconds prior to starting after receiving a remote start signal in normal operation modes and for time delay of seconds prior to ramp-to-idle or shutdown after signal to stop in normal operation modes. The generator set control will monitor the load during operation of the generator set, and if the total load on the set is less than 10% of rated it will reduce the operation time for the time delay stop in order to prevent extended operation of the engine at very light load levels. Default for both time delay periods is 0 seconds. Engine governing Isochronous governing - Controls engine speed within % for any steady state load from no load to full load. Frequency drift will not exceed + 0.5% for a 33 C (60 F) change in ambient temperature over an 8 hour period. Droop governing - Control can be adjusted to droop from 0 to 10% from no load to full load, using InPower. Temperature dynamics - Modifies the engine fuel system control parameters as a function of engine temperature. Allows engine to be more responsive when warm and more stable when operating at lower temperature levels. Isochronous load sharing control - See Paralleling Functions/Load sharing controls. Droop load sharing control - See Paralleling Functions/Load sharing controls. Idle mode - Engine governing can be regulated at an idle speed for a programmed period on start or stop of the engine. When the engine is operating at idle speed, the alternator excitation is automatically switched off. Alternator control Digital output voltage regulation - PowerCommand will regulate output voltage to within 0.5% for any loads between no load and full load. Voltage drift will not exceed + 0.5% for a 33 C (60 F) change in temperature in an 8 hour period. On engine starting, or sudden load acceptance, voltage is controlled to a maximum of 5% overshoot over nominal level. Torque-matched V/Hz overload control - The voltage roll-off set point and rate of decay (i.e., the slope of the V/Hz curve) is adjustable in the control. This function is automatically disabled when the control is in a synchronizing mode. Fault current regulation - PowerCommand will regulate the output current on any phase to a maximum of 3 times rated current under fault conditions for both single phase and three phase faults. In conjunction with a permanent magnet generator, it will provide 3 times rated current on all phases for motor starting and short circuit coordination purposes.

145 Isochronous (kvar) load sharing control - See Paralleling Functions/Load sharing controls. Droop (kvar) load sharing control - See Paralleling Functions/Load sharing controls. Protective functions On a warning condition, the control will indicate a fault by lighting the warning LED on the control panel and displaying the fault name and code on the operator display panel. The nature of the fault and time of occurrence are logged in the control. The service manual and InPower service tool provide service keys and procedures based on the service codes provided. On a shutdown condition, the control will light the shutdown LED on the control panel, display the fault name and code, initiate shutdown and lock out the generator set. The shutdown sequence of the generator set includes programmable cooldown at idle for fault conditions that do not endanger the engine. The control maintains a data log of all fault conditions as they occur and time stamps them with the controller run time and engine operating hours data. Adjustments to most set points are made using the InPower service tool. The control system includes a fault bypass mode that forces the system to function regardless of the status of protective functions. In this mode, the only protective functions that are operational are over speed, loss of both speed sensors, moving the control switch to the off position or pressing the emergency stop switch. The control maintains a record of the time that the mode is enabled and of all warning or shutdown conditions that have occurred while in the fault bypass mode. Many protective functions within the control system are configurable for warning, shutdown or both (2 levels). Exceptions to this include functions such as over speed conditions, and loss of speed sensing. In addition, some warning functions can incorporate control functions as a consequence of a fault. System protective functions: Ground fault warning (option VAC class generator sets) - Ground (earth) fault sensing is adjustable over a range of amps with time delays of 0-1 second. May be configured for shutdown rather than alarm. Configurable alarm and status inputs - PowerCommand will accept up to four alarm or status inputs (contact closed to ground) to indicate customerspecified conditions. The control is programmable for warning, shutdown or status indication and for labeling the input (up to 24 characters). Sixteen additional faults can be input to the control via the network. Breaker fail to close and breaker auxiliary contact warning or shutdown - When the paralleling control signals a circuit breaker to close, it will monitor the breaker auxiliary contacts and verify that the breaker has connected the generator set to the system bus. If the control does not sense a breaker closure within 0.5 second of the close signal, the control will monitor the phase relationship between the generator set and the bus. If this indicates that the generator set is not closed to the bus, the breaker fail to close alarm will be indicated, the breaker will be opened and the generator set shut down. If the phase relationship monitor indicates that the generator set is in parallel with the bus, circuit breaker auxiliary contact failure will be indicated and the generator set will continue to run in normal operation mode. Breaker fail to open warning - The control system monitors the operation of breakers that have been signaled to open. If the breaker does not open within 1 second of initiation of signal, a breaker fail to open warning is initiated. The control will logically allow the generator set to continue to run if shutdown of the generator set with the breaker closed will cause potential damage or operating problems. Bus or generator set PT input calibration error - The control system monitors the sensed voltage from the bus and generator set output voltage-potential transformers. When the paralleling breaker is closed, it will indicate a warning condition when they read different values. Emergency stop - Annunciated whenever the local or remote emergency stop signal is received. Alarm panel distinguishes between local or remote operation. AmpSentry protective relay AmpSentry protective relay is a UL Listed comprehensive monitoring and control system integral to the PowerCommand Control System that guards the electrical integrity of the alternator and power system by providing protection against a wide array of fault conditions in the generator set or in the load. It also provides single and three phase fault current regulation so that downstream protective devices have the maximum current available to quickly clear fault conditions without subjecting the alternator to potentially catastrophic failure conditions. See document R1053 below for a full size time over current curve. The control does not include protection required for interconnection to a utility (mains) service. Over current warning - Output current on any phase at more than 110% of rating for more than 60 seconds. Over current shutdown (51V) - Output current on any phase is more than 110%, less than 175% of rating and approaching thermal damage point of alternator. Control includes algorithms to protect alternator from repeated over current conditions over a short period of time. The control does not include instantaneous trip functions, as they are not necessary for alternator protection and complicate short circuit coordination (discrimination).

146 AMPS (TIMES RATED) ALTERNATOR THERMAL DAMAGE CURVE AMPSENTRY PROTECTION 100 Short circuit shutdown (51) -Output current on any phase is more than 175% of rating at time of shutdown. The control replicates the function of a 51V relay by discriminating between short circuit conditions and shutdown conditions, and shutting down the genset as fast as is necessary on a short circuit condition while operating as long as is possible on an overload condition. Control includes algorithms to protect alternator from repeated over current conditions over a short time. High AC voltage shutdown (59) - Output voltage on any phase exceeds preset values. Time to trip is inversely proportional to amount above threshold. Values adjustable from % of nominal voltage, with time delay adjustable from seconds. Default value is 110% for 10 seconds. Low AC voltage shutdown (27) - Voltage on any phase has dropped below a preset value. Adjustable over a range of 50-95% of reference voltage, time delay 2-10 seconds. Default value is 85% for 10 seconds. Function tracks reference voltage. Control does not nuisance trip when voltage varies due to the control directing voltage to drop, such as during a voltage roll-off during synchronizing. Under frequency shutdown (81u) - Generator set output frequency cannot be maintained. Settings are adjustable from 0-10 Hz below nominal governor set point, for a 0-20 second time delay. Default: 6 Hz, 10 seconds. Under frequency protection is disabled when excitation is switched off (such as when engine is operating in idle speed mode or the synchronizer is enabled). Over frequency shutdown/warning (81o) - Generator set is operating at a potentially damaging frequency level. Defaults: Disabled. Over load (kw) warning - Provides a warning indication when engine is operating at a load level over a set point. Adjustment range: % of rated kw, second delay. Defaults: 105%, 60 seconds. Reverse power shutdown (32) - Adjustment range: 5-20% of standby kw rating, delay 1-15 seconds. Defaults: 10%, 3 seconds. Sync check (25) - Verifies that the generator set is operating in synchronism with the system bus prior to allowing the paralleling breaker to close. Includes dead bus sensing capability. Fail to synchronize warning or shutdown - Indicates that the generator set could not be brought to synchronization with the system bus. Configurable for warning or shutdown and adjustable for time delay of seconds. Default is 120 seconds. Phase sequence sensing shutdown - Verifies that the generator set phase sequence matches the bus prior to allowing the paralleling breaker to close. The generator set will shutdown if the generator set and bus phase sequence do not match. Reverse Var shutdown - Shutdown level is adjustable: 15-50% of rated Var output, delay seconds. Defaults: 20%, 10 seconds. High alternator temperature (option). Engine protection Over speed shutdown - Default setting is 115% of nominal. Low lube oil pressure shutdown - Level is preset to match the capabilities of each engine. Control includes time delays to prevent nuisance shutdown signals. Low lube oil pressure warning - Level is preset to match the capabilities of each engine. Control includes time delays to prevent nuisance shutdown signals. High coolant temperature shutdown.

Separate indication is provided for fail high or low. High crankcase blowby level warning. High fuel temperature warning. High intake manifold temperature/pressure. Aftercooler cooler inlet over temperature. Paralleling functions (optional) First Start Sensor System - PowerCommand provides a unique control function that positively prevents multiple generator sets from simultaneously closing to an isolated bus under black start conditions. The First Start Sensor system is a communication system between generator sets that allows the generator sets to work together to determine which generator set in a system should be the first to close to the bus. The system includes an independent backup function, so that if the primary system is disabled the required functions are still performed. Synchronizer - PowerCommand incorporates a digital synchronizing function to force the generator set to match the phase relationship and voltage of the generator set output with the system bus or utility grid. The synchronizer includes provisions to provide proper operation even with highly distorted bus voltage waveforms. The synchronizer includes adjustments for phase angle window (5-20 ) and time delay (0.5-5 seconds). The synchronizer is 3-phase sensing, and includes controls to directly operate a paralleling breaker. The breaker controls include fail to open and fail to close protection. Load sharing controls - The generator set control includes an integrated load sharing control system for both real (kw) and reactive (kvar) loads when the generator set(s) are operating on an isolated bus. The control Our energy working for you Cummins Power Generation Inc.All rights reservedspecifications subject to change without noticecummins Power Generation and Cummins are registered trademarks of Cummins Inc.

Other company, product, or service names may be trademarks or service marks of others. S-1444h (4/08) Page 7 of 10 system determines kw load on the engine and kvar load on the alternator as a percent of generator set capacity, and then regulates fuel and excitation systems to maintain system and genset at the same percent of load without impacting voltage or frequency regulation. The control can also be configured for operation in droop mode for kw or Kvar load sharing. Load govern controls - When PowerCommand receives a signal indicating that the generator set is paralleled with an infinite source such as a utility (mains) service, the generator set will operate in load govern mode. In this mode the generator set will synchronize and close to the bus, ramp to a pre-programmed kw and kvar load level, and then operate at that point. Control is adjustable for kw values from 0-100% of standby rating, and power factor (leading). Default setting is 80% of standby and 1.0 power factor. The control includes inputs to allow independent control of kw and kvar load sharing level by a remote device while in the load govern mode. The rate of load increase and decrease is also adjustable in the control. Load demand control - The control system includes the ability to respond to an external signal to initiate load demand operation. On command, the generator set will ramp to no load, open its paralleling breaker, cool down, and shut down. On removal of the command, the generator set will immediately start, synchronize, connect, and ramp to its share of the total load on the system. Power transfer control (optional) The Power transfer control feature allows PowerCommand to provide integrated automatic power transfer functions including source availability sensing and transfer device (circuit breaker) monitoring and control. The control is configurable for open transition, fast transfer (100 ms), or soft (ramping) sequences of operation. Standard functions include: 3-phase (line-to-neutral) close differential under voltage sensing for utility (mains) service. Sensing for pickup in an adjustable range from % of nominal, with default at 95% of dropout setting. Dropout is configurable 75-98% of pickup, with default at 85%. 3-phase over voltage sensing for normal utility service adjustable for pickup at % of dropout and dropout configurable for % of nominal. Time delay is adjustable in a range of seconds. Default is disabled and is enabled using InPower. Under frequency sensing for normal utility service. Adjustment range is 80-95% of nominal. Default is disabled and is enabled using InPower. Configurable sequence of operation with or without adjustable program-transition capability. Adjustment range is 0-60 seconds. Remote exercise feature accepts a remote signal to initiate with or without load testing, or testing can be

148 initiated by the operator. Test sequence may include a programmed idle period prior to acceleration to rated voltage and frequency, and after cool down. Test may be configured to be performed with load or without load. Time delay start and stop as described in this document; time delay transfer adjustable in a range of seconds and retransfer in a range of seconds; all in 1-second increments. Fail to disconnect timer is adjustable in a range of 0.1 to 120 seconds. Environment The control is designed for proper operation without recalibration in ambient temperatures from -40 C to +70 C (-40 F to +158 F) and for storage from -40 C to +80 C (-40 F to +176 F). Control will operate with humidity up to 95%, non-condensing and at altitudes up to 5000 m (13,000 ft). The operator control panel has a single membrane surface which is impervious to the effects of dust, moisture, oil and exhaust fumes. The panel uses sealed membrane or oiltight switches to provide long reliable service life in harsh environments. The control system is specifically designed for resistance to RFI/EMI and to resist the effects of vibration to provide a long reliable life when mounted on a generator set. The control includes transient voltage surge suppression to provide compliance to referenced standards. The control is mounted on a vibration-isolated structure attached to the generator set skid and includes all generator set wiring factory-installed. Control interface Input signals to the PowerCommand control include: Remote start signal - May be connected via either discrete signal or Lon Network or both for premium reliability. Discrete signal is normally open contact to ground or normally closed contact that opens to indicate start signal. Separate signal inputs available for emergency start and non-emergency start. Remote emergency stop. Low main or day tank fuel level warning. Remote alarm reset. Load demand stop. Utility parallel (load govern) mode command. Configurable customer inputs - Control includes provisions for (4) input signals from customer discrete devices. (16) additional input signals can be implemented with the use of external network modules. Output signals from the control include: Generator set running signal - Fused normally open contact rated 5 A at 30 VDC/180 VAC, closes to indicate generator set is running. Generator set common shutdown signal - Selfprotected relay driver. Load shed signal - Self-protected relay driver. Operation is configurable for under frequency or over kw load or both. Adjustment range is % of standby rating with time delay of seconds. Default settings are overload 105%, 60 sec, and under frequency 3 Hz below governor reference for 3 seconds. Ready to load signal - Self-protected relay driver. Operates when the generator set has reached 90% of rated speed and voltage and latches until generator set is switched to off or idle mode. Modem control signal - Self-protected relay driver. Paralleling breaker interface - Fused normally open relay contact (5 A, 30 VDC/180 VAC) for parallel breaker close signal and normally open contact for parallel breaker open signal.

161 CERTIFICATE OF COMPLIANCE SEISMIC DESIGN OF NONSTRUCTURAL COMPONENTS AND SYSTEMS Notes and Comments: 1. All equipment listed herein successfully passed the seismic acceptance criteria for shake testing non-structural components and systems as set forth in the ICC AC-156. The Test Response Spectrum (TRS) enveloped the required response spectrum (RRS) for all units tested. The units cited in this certification were representative sample(s) of a contingent of models and all remained captive and structurally sound after the seismic shake simulation. The units also remained functionally operational after the simulation testing as functional testing was completed by the equipment manufacturer before and after the seismic simulations. Although a seismic qualified unit inherently contains some wind resisting capacity, that capacity is undetermined and is excluded from this certification. Snow/Ice loads have been neglected and thus limit the unit to be installed both indoors (covered by an independent protective structure) and out of doors (exposed to accumulating snow/ice) for ground snow loads no greater than 30 psf for all applications. 2. The following building codes are addressed under this certification: IBC 2012 referencing ASCE7-10 and ICC AC-156 IBC 2009 referencing ASCE7-05 and ICC AC-156 IBC 2006 referencing ASCE7-05 and ICC AC-156 IBC 2003 referencing ASCE7-02 and ICC AC-156 IBC 2000 referencing ASCE7-98 and ICC AC Refer to the manufacturer supplied installation drawings for anchor requirements and mounting considerations for seismic applications. Required anchor locations, size, style, and load capacities (tension and shear) are specified on the installation drawings. Mounting requirement details such as anchor brand, type, embedment depth, edge spacing, anchor-to-anchor spacing, concrete strength, special inspection, wall design, and attachment to non-building structures must be outlined and approved by the Engineer of Record for the project or building. Structural walls, structural floors, and housekeeping pads must also be seismically designed and approved by the project or building Structural Engineer of Record to withstand the seismic anchor loads as defined on the installation drawings. The installing contractor is responsible for observing the installation detailed in the seismic installation drawings and the proper installation of all anchors and mounting hardware. 4. For this certificate and certification to remain valid, this certificate must correspond to the Seismic Certification Label found affixed to the unit by the factory. The label ensures the manufacturer built the unit in conformance to the IBC seismic design criteria set forth by the Certified Seismic Qualification Agency, The VMC Group, and meets the seismic design levels claimed by this certificate. 5. When the site soil properties or final equipment installation location are not known, the soil site coefficient, F A, defaults to the Soil Site Class D coefficient. Soil Classes A, B, C, D, Seismic Risk Category I, II, III, IV, and Seismic Design Categories A, B, C, D, E, and F are all covered under this certification, limited by the S DS values on page 1, respective to the applicable building code, Importance factor, and z/h ratio. 6. Mechanical, Electrical, and Plumbing connections to the equipment must be flexibly attached as to not transfer load through the connection. The structural integrity of any conduit, cable trays, piping, ductwork and/or flexible connections is the responsibility of others. This certification does not guarantee the equipment will remain compliant to UL or NEMA standards after a seismic event. John P. Giuliano, PE President, The VMC Group Issue Date: November 6, 2009 Revision: January 30, 2014 Expiration Date: December 31, 2016 F-5610 Page3of3

Voltage Regulation: ±0.50% Random Voltage Variation: ±0.50% Frequency Regulation: ±0.25% Random Frequency Variation: ±0.25% Torsional Analysis and Testing: The generator set was tested to verify that the design is not subjected to harmful torsional stresses. A spectrum analysis of the transducer output was conducted over the speed range of 1200 to 2000 RPM. Transient Performance: The generator set was tested with the standard alternator to verify single step loading capability as required by NFPA 110. Voltage and frequency response on load addition or rejection were evaluated. The following results were recorded at 0.8 power factor: Cooling System: 50 C Ambient Full Load Acceptance: 0.5 in. H2O restriction Voltage Dip: 35.5 % Recovery Time: 4.6 Second Frequency Dip: 7.3 % Recovery Time: 5.2 Second The cooling system was tested to determine ambient temperature and static restriction capabilities. The test was performed at full rated load in elevated ambient temperature under stated static restriction conditions. Full Load Rejection: Voltage Rise: 16.7 % Recovery Time: 2.2 Second Frequency Rise: 3.0 % Recovery Time: 1.7 Second Electrical and Mechanical Strength: The generator set was tested to several single phase and three phase faults to verify that the generator can safely withstand the forces associated with short circuit conditions. The generator set was capable of producing full rated output at the conclusion of the testing.

175 Construction The relay is provided in a non-conducting phenolic case, with provisions for panel mounting or mounting to a standard DIN rail (panel mounting is recommended for mounting on a generator set). Relay components are fully potted with epoxy resin for vibration resistance and durability. The relay includes an integral terminal block assembly, which accepts wires up to 12-gauge. Relay function selection link (auto/hand reset). Environmental range - Operating -10 C to +60 C, storage -20 C to 70 C. DC supply burden 2.5 W. Transfer switch type selection link - (3-pole or 4-pole). System operation The ground fault relay continuously monitors the voltage across the neutral-to-ground bonding jumper and lights the ground fault alarm lamp on the generator set control when the connection is broken. When the generator set is running, the relay continuously monitors the neutral-to-ground generator set connection and lights the ground fault alarm lamp on the generator set control when a ground fault condition is sensed. Alarm condition can be cleared by pushing the reset switch on the generator set control panel. Actual ground fault current level can be monitored with a 0-1 ma meter, directly from the relay. A push button test switch is provided to simulate ground fault conditions and operate the relay and indication circuitry. Addition of the autoreset link activates automatic reset of the relay after the ground fault condition has cleared. System schematic Separately derived system connections (local grounding connection). Neutral-to-ground bonding jumper must be sized per code requirements. For non-separately derived systems (3-phase/4-wire systems with 3-pole transfer switch), the ground connection and the neutral-to-ground bonding jumper on the generator set are removed, and the 3-pole ATS link is added to the ground fault relay. For non-separately derived systems a label must be applied to the service entrance switchboard, indicating that removal of the equipment-bonding jumper can cause hazardous operating conditions.

195 SENS EnerGenius Technical Manual 4. NEUTRAL CONNECTION The grounded circuit conductor (neutral) should be connected to the terminal marked N on the input terminal block, TB1. 5. WIRE RATINGS A. All conductors should be rated for use at 90º C or higher. B. All input and output conductor sizes should be coordinated with the fault protection devices: 10A on AC input (14 AWG, 2.5 mm 2 typical), 30A on DC output (10 AWG, 6.0 mm 2 typical). 1 A on Alarm terminal block (20 AWG, 0.5 mm 2 typical). C. Before installation, ensure adequate battery to charger wire gauge. Wire gauge that is too small may activate the open battery detector and the charger will shut down. The maximum allowed resistance seen by the charger is found in TABLE 1. These figures already include an allowance for charger variations (they are 80% of the typical trip-point) and are for the complete circuit: total of battery leads, battery's internal resistance, and any external equipment. The total resistance seen by the charger must not exceed the following values: TABLE 1 12V 24V Maximum Resistance 58m 116m D. To determine the appropriate cable and length, please refer to the following table: Wire Size Resistance per Foot TABLE 2 Maximum Charger to Battery Distance (Ft.) Recommended Charger to Battery Distance (Ft.) AWG mm 2 m/ft. 12V 24V 12V 24V The above lengths consider the resistance of the battery and cables only and do not take into account any additional interconnects. The above lengths are for operation at 25C. For high temperature installations (40C) reduce lengths by 10%. In the case of high resistance in the cables to the battery the charger may cycle between AC Fail and Battery Fault LEDs (approximately every 10 seconds). Cable runs exceeding the proper length for the cable gauge used most often cause this problem. The appropriate solution is to change the cable gauge to properly correspond with the necessary cable length (see TABLE 2). In some cases where the resistance is not too far above maximum, the charger may recover after some time (approximately 10 minutes) and start charging the batteries. If it is not possible to decrease the system resistance the Battery Fault feature can be disabled. Please contact SENS at for further information. E. Refer to local electrical codes for additional requirements. F. See Section 10 for Terminal Block wire ranges. 6. FUSE RATINGS A.

208 OTPC transfer switch open and closed transition Amp Description OTPC transfer switches are designed for operation and switching of electrical loads between primary power and standby generator sets. They are suitable for use in emergency, legally required and optional standby applications. The switch monitors both power sources, signals generator set startup, automatically transfers power, and returns the load to the primary power source when the utility returns and stabilizes. OTPC transfer switches are available with closed transition transfer. By briefly connecting the two sources (for 100 msec or less), the transfer from the alternate source back to the normal source occurs without interruption in the power supply to loads. NEC All switches are UL 1008 Listed with UL Type Rated cabinets and UL Listed CU-AL terminals. All switches are certified to CSA 282 Emergency Electrical Power Supply for Buildings, up to 600 VAC. Suitable for use in emergency, legally required and standby applications per NEC 700, 701 and 702. All switches comply with NFPA 70, 99 and 110 (Level 1). All switches comply with NEMA ICS 10. All switches comply with IEEE 446 Recommended Practice for Emergency and Standby Power Systems. This transfer switch is designed and manufactured in facilities certified to ISO9001.

209 Transfer switch mechanism Specifications Voltage rating Arc interruption Neutral bar Auxiliary contacts Our energy working for you. Transfer switch mechanism is electrically operated and mechanically held in the Source 1 and Source 2 positions. The transfer switch incorporates electrical and mechanical interlocks to prevent inadvertent interconnection of the sources. Independent break-before-make action is used for both 3-pole and 4-pole/ switched neutral switches. This design allows use of sync check operation when required, or control of the operating speed of the transfer switch for proper transfer of motor and rectifier-based loads (programmed transition feature). True 4-pole switching allows for proper ground (earth) fault sensing and consistent, reliable operation for the life of the transfer switch. The neutral poles of the transfer switch have the same ratings as the phase poles and are operated by a common crossbar mechanism, eliminating the possibility of incorrect neutral operation at any point in the operating cycle, or due to failure of a neutral operator. High pressure silver alloy contacts resist burning and pitting. Separate arcing surfaces further protect the main contacts. Contact wear is reduced by multiple leaf arc chutes that cool and quench the arcs. Barriers separate the phases to prevent interphase flashover. A transparent protective cover allows visual inspection while inhibiting inadvertent contact with energized components. Switch mechanism, including contact assemblies, is third party certified to verify suitability for applications requiring high endurance switching capability for the life of the transfer switch. Withstand and closing ratings are validated using the same set of contacts, further demonstrating the robust nature of the design. 600 VAC, 50 or 60 Hz. Multiple leaf arc chutes provide dependable arc interruption. Operating temperature -40 F (-40 C) to 140 F (60 C) Storage temperature -40 F (-40 C) to 140 F (60 C) Humidity Altitude Surge withstand ratings Total transfer time (sourceto-source) Manual operation handles A full current-rated neutral bar with lugs is standard on enclosed 3-pole transfer switches. Two isolated contacts (one for each source) indicating switch position are provided for customer use. Contacts are normally open, and close to indicate connection to the source. Wired to terminal block for easy access. Rated at 10 amps continuous and 250 VAC maximum. UL recognized, and CSA-certified. Up to 95% relative, non-condensing Up to 10,000 ft (3,000 m) without derating Voltage surge performance and testing in compliance with the requirements of IEEE C62.41 (Category B3) and IEEE C Will not exceed 6 cycles at 60 Hz with normal voltage applied to the actuator and without programmed transition enabled. Transfer switches rated through 1000 amps are equipped with permanently attached operating handles and quick-break, quick-make contact mechanisms suitable for manual operation. Transfer switches over 1000 amps are equipped with manual operators. All switches must be de-energized before manual operation is attempted. Transition modes Open transition/programmed: Controls the time required for the device to switch from source to source, so that the load-generated voltages decay to a safe level before connecting to an energized source. Recommended by NEMA MG- 1 to prevent nuisance-tripping breakers and load damage. Adjustable 0-60 seconds, default 0 seconds. Programmed transition is standard on amp switches, and optional on amps. Open transition/in-phase: Initiates open transition transfer when in-phase monitor senses both sources are in phase. Operates in a break-before-make sequence. Includes ability to enable programmed transition as a back-up. If sources are not in phase within 120 seconds, switches from amps will transfer using programmed transition (not available on open transition switches over 1200 amps). Closed transition: Used in applications where loads are sensitive to the momentary power interruption that occurs when performing open transition between sources. Closed transition is accomplished by briefly (<100 msec) paralleling two good sources to eliminate the momentary break in the power supply. Closed transition is only available as an option on OTPC models from amps. Genset-to-genset: Either genset can be designated as the lead genset. If the lead genset goes down or is taken offline, the transfer switch starts the second genset and transfers the load. The control can be programmed to alternate between the two gensets at a set interval up to 336 hours (2 weeks) Cummins Power Generation Inc. All rights reserved.

This allows the engine to be more responsive when warm and more stable when operating at lower temperature levels. Isochronous governing - (where applicable) Capable of controlling engine speed within +/-0.25% for any steady state load from no load to full load. Frequency drift will not exceed +/-0.5% for a 33 C (60 F) change in ambient temperature over an 8 hour period. Droop electronic speed governing - Control can be adjusted to droop from 0 to 10% from no load to full load. Remote start mode - It accepts a ground signal from remote devices to automatically start the generator set and immediately accelerate to rated speed and voltage. The remote start signal will also wake up the control from sleep mode. The control can incorporate a time delay start and stop. Remote and local emergency stop - The control accepts a ground signal from a local (genset mounted) or remote (facility mounted) emergency stop switch to cause the generator set to immediately shut down. The generator set is prevented from running or cranking with the switch engaged. If in sleep mode, activation of either emergency stop switch will wakeup the control. Sleep mode - The control includes a configurable low current draw state to minimize starting battery current draw when the genset is not operating. The control can also be configured to go into a low current state while in auto for prime applications or applications without a battery charger. Engine starting - The control system supports automatic engine starting. Primary and backup start disconnects are achieved by one of two methods: magnetic pickup or main alternator output frequency. The control also supports configurable glow plug control when applicable. Cycle cranking - Is configurable for the number of starting cycles (1 to 7) and duration of crank and rest periods. Control includes starter protection algorithms to prevent the operator from specifying a starting sequence that might be damaging. Time delay start and stop (cooldown) - Configurable for time delay of seconds prior to starting after receiving a remote start signal and for time delay of seconds prior to shut down after signal to stop in normal operation modes. Default for both time delay periods is 0 seconds. Alternator control The control includes an integrated three phase line-toline sensing voltage regulation system that is compatible with shunt or PMG excitation systems. The voltage regulation system is a three phase full wave rectified and has an FET output for good motor starting capability. Major system features include: Digital output voltage regulation - Capable of regulating output voltage to within +/-1.0% for any loads between no load and full load. Voltage drift will not exceed +/- 1.5% for a 40 ºC (104 ºF) change in temperature in an eight hour period. On engine starting or sudden load acceptance, voltage is controlled to a maximum of 5% overshoot over nominal level. The automatic voltage regulator feature can be disabled to allow the use of an external voltage regulator. Droop voltage regulation - Control can be adjusted to droop from 0-10% from no load to full load. Torque-matched V/Hz overload control - The voltage roll-off set point and rate of decay (i.e. the slope of the V/Hz curve) is adjustable in the control. Fault current regulation - PowerCommand will regulate the output current on any phase to a maximum of three times rated current under fault conditions for both single phase and three phase faults. In conjunction with a permanent magnet generator, it will provide three times rated current on all phases for motor starting and short circuit coordination purpose. Protective functions On operation of a protective function the control will indicate a fault by illuminating the appropriate status LED on the HMI, as well as display the fault code and fault description on the LCD. The nature of the fault and time of occurrence are logged in the control. The service manual and InPower service tool provide service keys and procedures based on the service codes provided. Protective functions include: Battle short mode When enabled and the battle short switch is active, the control will allow some shutdown faults to be bypassed. If a bypassed shutdown fault occurs, the fault code and Our energy working for you Cummins Power Generation Inc.All rights reservedspecifications subject to change without noticecummins Power Generation and Cummins are registered trademarks of Cummins Inc.

237 description will still be annunciated, but the genset will not shutdown. This will be followed by a fail to shutdown fault. Emergency stop shutdowns and others that are critical for proper operation are not bypassed. Please refer to the Control Application Guide or Manual for list of these faults. Derate The Derate function reduces output power of the genset in response to a fault condition. If a derate command occurs while operating on an isolated bus, the control will issue commands to reduce the load on the genset via contact closures or Modbus. Configurable alarm and status inputs The control accepts up to four alarm or status inputs (configurable contact closed to ground or open) to indicate a configurable (customer-specified) condition. The control is programmable for warning, shutdown or status indication and for labeling the input. Emergency stop Annunciated whenever either emergency stop signal is received from external switch. Full authority electronic engine protection Engine fault detection is handled inside the engine ECM. Fault information is communicated via the SAE-J1939 data link for annunciation in the HMI. General engine protection Low and high battery voltage warning - Indicates status of battery charging system (failure) by continuously monitoring battery voltage. Weak battery warning - The control system will test the battery each time the generator set is signaled to start and indicate a warning if the battery indicates impending failure. Fail to start (overcrank) shutdown - The control system will indicate a fault if the generator set fails to start by the completion of the engine crack sequence. Fail to crank shutdown - Control has signaled starter to crank engine but engine does not rotate. Cranking lockout - The control will not allow the starter to attempt to engage or to crank the engine when the engine is rotating. Alternator protection AmpSentry Protective relay - A UL Listed comprehensive monitoring and control system integral to the PowerCommand Control System that guards the electrical integrity of the alternator and power system by providing protection against a wide array of fault conditions in the generator set or in the load. It also provides single and three phase fault current regulation so that downstream protective devices have the maximum current available to quickly clear fault conditions without subjecting the alternator to potentially catastrophic failure conditions. See document R1053 for a full size time over current curve. High AC voltage shutdown (59) - Output voltage on any phase exceeds preset values. Time to trip is inversely proportional to amount above threshold. Values adjustable from % of nominal voltage, with time delay adjustable from seconds. Default value is 110% for 10 seconds. Low AC voltage shutdown (27) - Voltage on any phase has dropped below a preset value. Adjustable over a range of 50-95% of reference voltage, time delay 2-20 seconds. Default value is 85% for 10 seconds. Function tracks reference voltage. Control does not nuisance trip when voltage varies due to the control directing voltage to drop, such as during a V/Hz roll-off during synchronizing. Under frequency shutdown (81 u) - Generator set output frequency cannot be maintained. Settings are adjustable from 2-10 Hz below reference governor set point, for a 5-20 second time delay. Default: 6 Hz, 10 seconds. Under frequency protection is disabled when excitation is switched off, such as when engine is operating in idle speed mode. Over frequency shutdown/warning (81o) - Generator set is operating at a potentially damaging frequency level. Settings are adjustable from 2-10 Hz above nominal governor set point for a 1-20 second time delay. Default: 6 Hz, 20 seconds, disabled.

266 SENS EnerGenius Technical Manual 4. NEUTRAL CONNECTION The grounded circuit conductor (neutral) should be connected to the terminal marked N on the input terminal block, TB1. 5. WIRE RATINGS A. All conductors should be rated for use at 90º C or higher. B. All input and output conductor sizes should be coordinated with the fault protection devices: 10A on AC input (14 AWG, 2.5 mm 2 typical), 30A on DC output (10 AWG, 6.0 mm 2 typical). 1 A on Alarm terminal block (20 AWG, 0.5 mm 2 typical). C. Before installation, ensure adequate battery to charger wire gauge. Wire gauge that is too small may activate the open battery detector and the charger will shut down. The maximum allowed resistance seen by the charger is found in TABLE 1. These figures already include an allowance for charger variations (they are 80% of the typical trip-point) and are for the complete circuit: total of battery leads, battery's internal resistance, and any external equipment. The total resistance seen by the charger must not exceed the following values: TABLE 1 12V 24V Maximum Resistance 58m 116m D. To determine the appropriate cable and length, please refer to the following table: Wire Size Resistance per Foot TABLE 2 Maximum Charger to Battery Distance (Ft.) Recommended Charger to Battery Distance (Ft.) AWG mm 2 m/ft. 12V 24V 12V 24V The above lengths consider the resistance of the battery and cables only and do not take into account any additional interconnects. The above lengths are for operation at 25C. For high temperature installations (40C) reduce lengths by 10%. In the case of high resistance in the cables to the battery the charger may cycle between AC Fail and Battery Fault LEDs (approximately every 10 seconds). Cable runs exceeding the proper length for the cable gauge used most often cause this problem. The appropriate solution is to change the cable gauge to properly correspond with the necessary cable length (see TABLE 2). In some cases where the resistance is not too far above maximum, the charger may recover after some time (approximately 10 minutes) and start charging the batteries. If it is not possible to decrease the system resistance the Battery Fault feature can be disabled. Please contact SENS at for further information. E. Refer to local electrical codes for additional requirements. F. See Section 10 for Terminal Block wire ranges. 6. FUSE RATINGS A.

267 PowerCommand Annunciator Discrete Input or PCCNet Description The Universal Annunciator Module provides visual and audible indication of up to 20 separate alarm or status conditions, based on discrete (relay) inputs or network inputs. Each LED can be controlled by either a discrete wire input or by a signal on the PCCNet network sent from an external device, such as a PCC1301 or PCC2100 (version 2.4 or later) control. In addition to the LEDs, the annunciator can control four custom relays based on signals received over the PCCNet. When one of the annunciator s discrete inputs is activated, the annunciator will broadcast that information over the network. By taking advantage of the network, discrete inputs and custom relays, the annunciator can be used as expanded I/O for a genset controller. Easily installed in a location to give immediate notification of an alarm or warning status. Designed to give operating/monitoring personnel quick-glance status information. The module directly senses battery voltage to provide green/yellow/red alarm and status information for that parameter. Genset controller complies with NFPA level two requirements when used with the display but without the annunciator panel. When used with the annunciator it meets NFPA level one requirements (emergency and standby power systems). The annunciator module can also be used for monitoring of transfer switch or other equipment status. Features Visual and audible warnings of up to 20 separate alarm or status conditions. LEDs can be controlled either via PCCNet or discrete input. Status of discrete inputs is broadcast on network. Four custom relays can be controlled over the PCCNet network. Configurable LED color (red, yellow or green) and selectable horn operation allows maximum flexibility. Standard NFPA 110 label, field configurable for other alarm status and conditions. Each audible alarm is annunciated, regardless of the number of existing alarm conditions displayed. Sealed membrane panel design provides environmental protection for internal components and is easy to clean. Configurable for negative (ground) input or positive input. Integral DC voltage sensing.

275 Day Tank Systems: Other Information Fuel containment basins While containment basins for day tanks are optional, most day tank users include them with their systems because they substantially reduce the risk of fuel leaking into the surrounding environment due to a tank rupture. Tramont strongly recommends the use of a containment basin. Local codes frequently require a containment basin. There are two types of containment, a rupture basin and double wall. Rupture Basin A rupture basin is open-top. The day tank is placed in the basin. Because water and debris can collect in the containment area, rupture basins are used only for indoor applications. Double Wall A double wall basin is similar to the rupture basin, except the top is sealed and welded into place around the tank. An additional pressure relief vent cap is required to vent the containment area. Double wall tanks typically are used in outdoor applications. Depending upon local codes, they also may be required for indoor applications. Other options may be required to fully weatherproof the tank. Basin Capacity Basins are available in standard sizes of 150% and 200% of the tank capacity. A 150% capacity basin is adequate for most applications; however, some jurisdictions require a 200% capacity basin. Check with your local fire marshal or other code-enforcement authorities to verify basin requirements. Special Dimensions Dimensions for standard day tanks are listed on page 7. Please consult Tramont if your application requires special dimensions. Underwriters Laboratories listing All Tramont standard day tank models are available with Underwriters Laboratories listing. UL listed tanks include heavy duty stiffeners required per UL-142 standards. All primary and secondary tank sections are pressurized at 3-5 psi and leak-checked to ensure integrity of weld seams per UL-142 standards. The Tramont System 2000PLUS Electronic Control Module, standard on all Tramont TRS Series tanks, is UL- 508 listed. Tramont day tanks also are built in accordance with The Standard of Installation and Use of Combustible Engine and Gas Turbines, NFPA N.

276 Day Tank Control Specification System 2000PLUS ECM General This section covers the electrical description and installation of the standard TRAMONT electrical control module (ECM). Installation of the SYSTEM 2000 should be performed by a qualified electrician. These specifications describe the standard SYSTEM 2000 ECM as the most full featured UL508 listed fuel transfer system in the industry. Description The heart of the SYSTEM 2000 ECM is an electrical analog float gauge sends a signal to the ECM for: fuel level indication, pump control, high fuel level warning, low fuel level warning, low fuel level shut off, fuel in rupture basin warning, low fuel in remote tank warning and an ECM function signal. All signals and warnings are provided with N.O. and N.C. contacts for remote annunciation. The ECM can be manually controlled by ON, OFF, and TEST push buttons. In addition, an internal test button allows for a periodic test of all warning LEDs and remote annunciation relays. Functions The purpose of the ECM is to maintain the fuel level of the day tank by controlling the pump/motor. The pump is off at the normal fuel level and is activated at 87% full. A pump running indicator LED is on when the pump is activated. A motor control relay is prewired to pump motor. WARNING: When ECM OFF push button is engaged the unit is disabled, however, 120 VAC power is still present within the ECM indicated by the power on LED. Options Standard - UL 508 listed control module Duplex pumping system. Adds 2nd pump and motor for safety redundancy. Control alternates lead pump Controls are available for 12 VDC operation. Single or duplex. Please consult factory for specifications Controls are available for 24 VDC operation. Single or duplex. Please consult factory for specifications Pump running contacts for remote annunciation Critical high shutdown. Separate float switch senses high fuel level, disengaging motor and closing N.C. solenoid valve. Warning relay supplied for remote annunciation. Incoming Power The ECM is powered by a customer-supplied 120 VAC line. Power terminals are accessible by removing four cover screws on the ECM and removing the ECM cover exposing the terminal strip. Wires should be run through knockout provided. Level Sensor The day tank s level is determined by an electrical analog float gauge located beneath the ECM. The sensor sends a 0-90ohm signal to the ECM, which converts this signal into a precise fuel level. Fuel level is indicated by nine incremental LEDs on the ECM from EMPTY to FULL. Alarms The ECM has five standard alarm conditions. Each alarm is indicated locally by an LED and remotely by wiring to supplied relays. A normally open and normally closed contact is provided for customer connections. Contacts are rated at 1 amp tungsten, 120 VAC or 24 VDC. A. High fuel - activates at 106% of normal fuel level with a two second change of state time delay. B. Low fuel - activates at 62% of normal fuel level. This enables the customer time to react to a potential problem before low fuel shutdown occurs. C. Low fuel shutdown - activates at 6% of normal fuel level. This enables customer to shut down engine generator before fuel runs out, preventing loss of prime or engine damage. D. Fuel in rupture basin - with a rupture basin float switch, (option #2930) the ECM will signal if fuel is in the rupture (containment) basin. E. ECM functional - the ECM performs many internal checks (including float sensor signal verification) to ensure proper operation. If a fault occurs, this LED will go out (or flash if an erratic signal is present) and deenergize the relay. It is suggested that the customer wire to the normally closed contact thereby providing a signal if a fault does occur. Mode There are four modes of operation on the ECM: A. Off - This pushbutton disables the ECM for routine maintenance to the tank system without disrupting the ECM. Caution: ECM functional de-energizes, which can activate a customer alarm wired to this relay. B. On - This pushbutton activates the ECM after the Off pushbutton has been depressed. On any initial powerup condition, after a power outage, the ECM will automatically turn on. C. Test - This pushbutton will test all front panel LEDs for three seconds and activate pump/motor for as long as the button is depressed. All alarm relays will not activate but will maintain their original state. D. Internal test - This pushbutton, located inside the ECM, will test each LED and remote annunciation relay in sequential order - High fuel to ECM functional. Note: It is recommended that both the external and internal test switch be activated as part of a periodic maintenance program to ensure reliable operation of the day tank N.

279 Design Considerations of a Day Tank Pump/ Fuel Transfer System Designing pumping systems can be a very complex task. This general guide is designed to assist the designer in the proper specification of the fuel transfer system. The three main areas to be covered by this paper are pump lift, pump head and pump prime. In critical or borderline applications, an experienced hydraulic engineer should always be consulted. Pump Lift A pump will lift fuel by displacing air from suction to discharge line. This creates low pressure in the suction line which allows the higher atmospheric pressure (14.7 psi at sea level) to lift liquid into this vacuum. If a perfect vacuum could be created and maintained fuel could theoratically be lifted to 34 feet. Since a perfect vacuum cannot be created, the lift a pump can actually achieve is approximately 50% of theoretical lift or 17 feet (7.4 psi). To determine the total available lift, the following factors need to be considered: 1. Vertical distance from tank to pump 2. Total length of pump and size 3. Fittings in line 4. Elevation above sea level 1. The vertical distance the pump needs to lift fuel is the main factor in lifting capabilities. This measurement should be taken from the bottom of the main tank to the pump s inlet port. 2. The total length of piping and size in important due to internal friction. This will reduce lift and must be considered. (see table one) All calculations are based on 60 F temperture. Frictional resistance will increase as temperature decreases. 3. Fitting in the line will disrupt flow and create friction. These fittings include elbows, tees and unions. (see table two) Valves also need to be checked for possible pressure drops. 4. Elevation above sea level is important since the atmospheric pressure acting against the pump s vacuum is reduced, thereby reducing lift. (see table three) Example One Given: Vertical distance Total length of pipe Pipe size Pump size Fitting in line Elevation above sea level 12 feet 100 feet 1 in diameter 2 GPM 3 elbows, no valves 3,000 feet Solution: Referring to table two, an elbow equals 2.6 feet of pipe. (2.6 x 3 elbows = 7.8 feet) The corrected length of pipe is now feet. Referring to table one, the feet is divided by 100 and multiplied by the.5 our actual head loss is.54 feet. Therefore, the total lift needed for this system is the vertical didtance plus.54 feet or feet. Since the pump is safely capable of lifting 15 feet at a 3,000 foot elevation, (see table three), the previous example will perform satisfactorily. However, if a 3/8 diameter pipe would have been used, the head loss would have been feet. Adding the vertical distance to this figure equals feet. The pump would not be able to lift the fuel. If the plumbing system cannot be built under a 17 foot lift limitation (at sea level), a remote pumping station must then be used. This will be placed between the main tank and the day tank. The proper placement is determined by the pump lift calculation and the following pump head calculations. Pump Head The pump s head is the theoretical vertical distance a pump will push fuel. Day tank standard ( 2 GPM/ 1/3 HP) pumps have 231 feet of head (100 psi). Refer to table four for larger pump and motor discharge rates. Because of electrical convenience the pump is normally located on the day tank, but when pump lift demands are exceeded the remote pumping station is required. This allows us to utilize the head (pushing) capabilities of the pump. To determine the total available head three factors need to be considered: 1. Vertical distance from pump to day tank 2. Total length of pipe and size 3. Fittings in line 1. The vertical distance the pump needs to push the fuel is the main factor in head capabilities. This measurement should be taken from the output port on the pump to the day tank s upper most piping connection. 2. Length and size of pipe need to be considered in the same manner as the lift calculations. 3. Fittings also are calculated in the same manner. Note: Elevation does not need to be considered in head calculations. Example Two Given: Vertical distance 150 feet Total length of pipe 175 feet Pipe size 3/4 in diameter Fittings 2 elbows, 1 check valve, 1 solenoid valve Pump 7 GPM Solution: Referring to table two, a 3/4 elbow equals 2.1 feet of pipe (2.1 x 2= 4.2). The check valve equals 5.3 feet of pipe. Also, the solenoid valve has a 3 psi drop, (consult manufacturer), or 6.93 feet (3 x 2.31). The total adjusted length of pipe is : = feet. Referring to table one, 191 feet of 3/ 4 pipe with a 7 GPM pump interpolates to 29.2 feet of head loss (1.91 x 15.3). Therefore, total equivalent height is ( ) feet. Note: The resulting pressure at day tank is (231 feet feet) divided by 2.31 = 22 psi. Since the pump will push fuel to a height of 231 feet, this system will work N.

280 Design Considerations continued... Pump Prime Maintaining the prime on a pump is of critical importance. Fuel must be maintained in the suction side pipe with no air pockets. Foot valves at the main tank or check valves at the day tank can be used to prevent fuel flowing back to the main tank and losing prime. Pump cavitation is the inability for a pump to discharge fuel properly and can occur for many reasons: 1. Total equivalent lift too high for pump 2. Total equivalent head too high for pump 3. Restrictions in lines 4. Air leaks 5. Improperly plumbed systems Cavitation can occur gradually and will eventually ruin a pump. Vertical piping loops or traps should be avoided when designing a pumping system. Air pockets can become trapped in the high point of the vertical loop, resulting in pump cavitation. A hand pump is recommended for initial priming to avoid undue wear on the fuel pump. If the fuel pump must be used for initial priming, do not run for more than 60 seconds. Fuel should be flowing within that time. A fuel strainer is also recommended on the inlet side of the pump. Foreign particles entering the pump chamber will deminish its life expectancy. The strainer should be checked periodically to avoid particle buildup, which would limit pumping capabilities. Summary Proper engineering practices should always be used when calculating pump head and especially pump lift. By following these guidelines, costly repair due to improper installations can be avoided. Notes: 1. 1 psi = 2.31 feet of head is the conversion for water. As a general rule, this is a safe conversion for #2 diesel fuel. 2. For more precise calculations refer to the formulas and conversions listed below. A. Head in feet = PSI x 2.31 Specific Gravity B. PSI = Head x Specific Gravity 2.31 C. Specific Gravity of #2 diesel fuel -.88 at 60 F D. Weight of #2 diesel fuel lbs/gallon 3. All calculations are based on a 60 F temperature. Allowances must be made for extreme temperature variances. A. Viscosity of #2 diesel fuel 100 F 70 F 20 F 0 F -30 F B. An immersion heater is recommended for below 32 F applications.

283 Mechanical and plumbing guide: Day tank systems Mechanical installation This guide covers the mechanical installation of a standard Tramont day tank system. Installation should be performed by a qualified mechanical installer or plumber experienced in black iron piping, valves and connections. This guide primarily covers "standard" tanks; that is, tanks without optional accessories or equipment. Certain optional devices may require special consideration during installation. For TRE-Series tanks also see "Electrical installation guide: TRE- Series Day Tanks." For TRS-Series tanks also see "System 2000PLUS" specification sheet.!warning! THIS TANK IS DESIGNED AND CONSTRUCTED TO HOLD DIESEL FUEL ONLY. Tank placement Upon receipt of the Tramont day tank, inspect for obvious signs of shipment damage. If damage is visible (dents, waterlogging, etc.), notify the freight company and file a claim for damages with them. This step must take place on the receiving end of the shipment; Tramont cannot do this for the purchaser or end user. Unpack the unit and inspect closely. The Tramont day tank can withstand normal stresses of shipping. However, rough handling, such as dropping the unit, may result in scratches, dents and damage to tank components and weld seams. Again, if you detect any signs of damage notify the freight company immediately. Place the tank as close to the gen-set as practical. It should be fully accessible from all sides. The front of the unit must be visible and accessible. Position the tank so that fittings and vents can be easily connected and checked. Make sure that there is room to access the basin/tank drain. Generally a minimum of 6" - 8" from any wall is required for piping installation. Allowing adequate space for piping will make future repair and maintenance much easier. Slots are located on the base of the tank if you choose to bolt it to the floor. Complete all piping before bolting the tank to any surface. This will make it much easier to correct any misalignment of piping. The day tank is not designed to absorb the force exerted by improperly aligned pipe. "Forcing" pipes to line up with the fittings may damage the tank. Plumbing connections Day tanks typically are installed with three 90 elbows in the fuel line between the day tank and the point where the line is firmly fixed to a wall or floor. This will facilitate minor adjustments when leading the piping to the tank. Pipe unions should be installed as needed to allow for future breakdown or maintenance of pipes. All threaded connections shall be covered with Teflon tape, thread sealant or comparable material. DO NOT use any sealant that is not compatible with #2 diesel oil. All threaded connections must be tightened leaktight. IMPORTANT: Gen-set installations generally are not set up so that high pressure can form in piping lines, and the Tramont day tank is not a pressure vessel. However, all connections still should be tightened so that the piping can withstand considerable pressure if necessary. Use only clean, new pipe connections. Rust, dirt, tars and other contaminants can prevent proper operation of tank components such as pumps, and may result in damage or destruction of these components. Engine supply The engine supply fitting (1" NPT) is located on the lefthand side at the bottom rear of tanks without a basin. On tanks with a basin the supply fitting is located on the top rear of the tank, and a dip tube extends to the bottom of the tank. Follow the gen-set supplier's requirements for pipe size, flex hose and connections to the engine. Fuel return On tanks without a basin there are two 1" NPT fuel return fittings on the back of the tank. One is located at the lower right-hand side of the tank, the other is located near the top of the tank. On tanks with a basin there is a single fuel return fitting on the back of the tank near the top. The fuel return fittings are for excess hot fuel returned from the engine. If your tank does not include a basin Tramont recommends using the bottom fuel return fitting. Seal the unused fuel return fitting with a 1" NPT black iron pipe plug. Another option is to pipe the fuel return line directly to the main tank, thereby eliminating a possible fuel temperature increase in the day tank. Overflow The 1" NPT overflow fitting is located at the upper rear of the tank. It prevents overfilling of the day tank by routing excess fuel directly back to a main tank N. Humboldt Boulevard Milwaukee, WI Phone: Fax: sales@tramont.com

284 Mechanical and plumbing guide, continued... Main tank below day tank (TRE & TRS) In instances where the main tank is located below the day tank, the overflow line must be piped in a continuous downward path to the main tank.!warning! BECAUSE THE OVERFLOW LINE OPERATES VIA GRAVITY, THERE CAN BE NO UPFLOW OR TRAPS IN THE LINE. DO NOT RESTRICT OR DOWNSIZE THE DIAMETER OF THE PIPE. Tramont recommends overfilling the day tank initially to make sure that the overflow line is working properly. Main tank above day tank (TRS only) In instances where the main tank is above the day tank, the overflow line cannot be piped via gravity. The overflow line should not be plugged. Instead, Tramont strongly recommends the use of a reverse pumping system to return excess fuel to the main tank. Failure to use a reverse pumping system may result in a fuel spill should the day tank become overfilled. Reverse pumping systems are available on Tramont TRS Series day tanks. See Tramont specification "Diesel Fuel Day Tank with Supply Pump and Motor." Vents There is a 1-1/4" NPT normal vent fitting at the top rear of tank. This is an atmospheric vent and must be piped in a continuous upward path with no traps. In installations with a main tank the normal vent must be piped higher than the main tank fuel level. The normal vent should be vented outside any enclosed spaces. The appropriate vent cap is available from Tramont or users may provide their own.!warning! DO NOT PLUG THE NORMAL VENT. THIS IS AN ATMOSPHERIC TANK ONLY AND IS NOT TO BE OPERATED UNDER PRESSURE. The tank also includes an NPT fitting for an emergency vent. The fitting will range in size from 2" to 5". Tanks with a sealed rupture basin also will include an emergency vent fitting on the containment area. The emergency vent fittings may not be plugged. The appropriate vent cap is available from Tramont or users may provide their own. This vent is designed to open should the tank become suddenly pressurized (in a fire, for example). Requirements for piping the emergency vent may vary by location. Consult local codes on piping, vent caps, vent location and other requirements. Drain Day tanks less than 300 gallons include a 3/8" NPT drain fitting. Tanks 300 gallons or larger include a 1" NPT drain fitting. On day tanks without a basin the drain fitting connects directly to the tank. On tanks with a basin the drain is connected to the containment area only. The tank is shipped with the drain fitting plugged. This plug may become loose during shipping. It is the installer's responsibility to verify the integrity of the drain and all other connections. In installations with a main tank the drain may be plumbed back to the main tank. An optional drain petcock or ball valve is available from Tramont. Fuel inlet (TRE & TRS Only) The fuel inlet to the day tank is located on the pump. The standard Tramont day tank pump includes a 3/8" NPT female threaded fitting. This fitting size may vary on optional pumps. Plumb the fuel supply line from the main tank to the day tank pump suction port. Properly align the piping so that stress is not exerted on the pump. IMPORTANT NOTE: Fuel contamination can decrease pump life, cause leaking valves and erratic gauge readings. Tramont strongly recommends the installation of a 100 mesh fuel strainer on the pump inlet. Piping (TRE & TRS) Tramont day tank pumps are rated for 17' of vertical lift at sea level. Long horizontal runs, small diameter pipe and restrictions such as elbows and valves can reduce lift. (See "Pump Capabilities" worksheet). Leaks in the pipe line will reduce or eliminate lift. Running the pump/motor with no fuel in the line may damage or destroy the pump and motor. Tramont strongly recommends that manifold fuel lines be avoided. Tramont also strongly recommends that the incoming fuel line be primed as close to the pump as possible prior to start-up. Testing The tank has been factory leak-tested at 3-5 PSIG per UL- 142 requirements. All lines to and from the day tank should be pressure tested for leaks. If they are available, close shutoff valves at both ends of the piping and apply pressure to desired levels. Lines that have only gravity flow should be tested to twice the head pressure that would exist if the lower end of the line were plugged and the line was filled with oil. Note: 2.68' of head = 1 PSIG.!WARNING! WHEN TESTING THE FUEL LINES DO NOT ALLOW THE TANK ITSELF TO BECOME PRESSURIZED IN EXCESS OF 5 PSIG. EXCESS PRESSURE MAY DAMAGE THE TANK. Mechanical inspection Verify that all valves are open and all lines are pressure tested and clear. Verify that the installation is in accordance with mechanical specifications and all local building codes. Day tank users, installers and specifying engineers should be familiar with NFPA 30 and 37, UL-142, local codes and any other applicable codes N.

295 Transfer switch mechanism Specifications Voltage rating Arc interruption Neutral bar Auxiliary contacts Our energy working for you. Transfer switch mechanism is electrically operated and mechanically held in the Source 1 and Source 2 positions. The transfer switch incorporates electrical and mechanical interlocks to prevent inadvertent interconnection of the sources. Independent break-before-make action is used for both 3-pole and 4-pole/ switched neutral switches. This design allows use of sync check operation when required, or control of the operating speed of the transfer switch for proper transfer of motor and rectifier-based loads (programmed transition feature). True 4-pole switching allows for proper ground (earth) fault sensing and consistent, reliable operation for the life of the transfer switch. The neutral poles of the transfer switch have the same ratings as the phase poles and are operated by a common crossbar mechanism, eliminating the possibility of incorrect neutral operation at any point in the operating cycle, or due to failure of a neutral operator. High pressure silver alloy contacts resist burning and pitting. Separate arcing surfaces further protect the main contacts. Contact wear is reduced by multiple leaf arc chutes that cool and quench the arcs. Barriers separate the phases to prevent interphase flashover. A transparent protective cover allows visual inspection while inhibiting inadvertent contact with energized components. Switch mechanism, including contact assemblies, is third party certified to verify suitability for applications requiring high endurance switching capability for the life of the transfer switch. Withstand and closing ratings are validated using the same set of contacts, further demonstrating the robust nature of the design. 600 VAC, 50 or 60 Hz. Multiple leaf arc chutes provide dependable arc interruption. Operating temperature -40 F (-40 C) to 140 F (60 C) Storage temperature -40 F (-40 C) to 140 F (60 C) Humidity Altitude Surge withstand ratings Total transfer time (sourceto-source) Manual operation handles A full current-rated neutral bar with lugs is standard on enclosed 3-pole transfer switches. Two isolated contacts (one for each source) indicating switch position are provided for customer use. Contacts are normally open, and close to indicate connection to the source. Wired to terminal block for easy access. Rated at 10 amps continuous and 250 VAC maximum. UL recognized, and CSA-certified. Up to 95% relative, non-condensing Up to 10,000 ft (3,000 m) without derating Voltage surge performance and testing in compliance with the requirements of IEEE C62.41 (Category B3) and IEEE C Will not exceed 6 cycles at 60 Hz with normal voltage applied to the actuator and without programmed transition enabled. Transfer switches rated through 1000 amps are equipped with permanently attached operating handles and quick-break, quick-make contact mechanisms suitable for manual operation. Transfer switches over 1000 amps are equipped with manual operators. All switches must be de-energized before manual operation is attempted. Transition modes Open transition/programmed: Controls the time required for the device to switch from source to source, so that the load-generated voltages decay to a safe level before connecting to an energized source. Recommended by NEMA MG- 1 to prevent nuisance-tripping breakers and load damage. Adjustable 0-60 seconds, default 0 seconds. Programmed transition is standard on amp switches, and optional on amps. Open transition/in-phase: Initiates open transition transfer when in-phase monitor senses both sources are in phase. Operates in a break-before-make sequence. Includes ability to enable programmed transition as a back-up. If sources are not in phase within 120 seconds, switches from amps will transfer using programmed transition (not available on open transition switches over 1200 amps). Closed transition: Used in applications where loads are sensitive to the momentary power interruption that occurs when performing open transition between sources. Closed transition is accomplished by briefly (<100 msec) paralleling two good sources to eliminate the momentary break in the power supply. Closed transition is only available as an option on OTPC models from amps. Genset-to-genset: Either genset can be designated as the lead genset. If the lead genset goes down or is taken offline, the transfer switch starts the second genset and transfers the load. The control can be programmed to alternate between the two gensets at a set interval up to 336 hours (2 weeks) Cummins Power Generation Inc. All rights reserved.

323 Service adjustments - The HMI includes provisions for adjustment and calibration of generator set control functions. Adjustments are protected by a password. Functions include: - Engine speed governor adjustments - Voltage regulation adjustments - Cycle cranking - Configurable fault set up - Configurable output set up - Meter calibration - Display language and units of measurement Engine control SAE-J1939 CAN interface to full authority ECMs (where applicable). Provides data swapping between genset and engine controller for control, metering and diagnostics. 12 VDC/24 VDC battery operations - PowerCommand will operate either on 12 VDC or 24 VDC batteries. Temperature dependent governing dynamics (with electronic governing) - modifies the engine governing control parameters as a function of engine temperature. This allows the engine to be more responsive when warm and more stable when operating at lower temperature levels. Isochronous governing - (where applicable) Capable of controlling engine speed within +/-0.25% for any steady state load from no load to full load. Frequency drift will not exceed +/-0.5% for a 33 C (60 F) change in ambient temperature over an 8 hour period. Droop electronic speed governing - Control can be adjusted to droop from 0 to 10% from no load to full load. Remote start mode - It accepts a ground signal from remote devices to automatically start the generator set and immediately accelerate to rated speed and voltage. The remote start signal will also wake up the control from sleep mode. The control can incorporate a time delay start and stop. Remote and local emergency stop - The control accepts a ground signal from a local (genset mounted) or remote (facility mounted) emergency stop switch to cause the generator set to immediately shut down. The generator set is prevented from running or cranking with the switch engaged. If in sleep mode, activation of either emergency stop switch will wakeup the control. Sleep mode - The control includes a configurable low current draw state to minimize starting battery current draw when the genset is not operating. The control can also be configured to go into a low current state while in auto for prime applications or applications without a battery charger. Engine starting - The control system supports automatic engine starting. Primary and backup start disconnects are achieved by one of two methods: magnetic pickup or main alternator output frequency. The control also supports configurable glow plug control when applicable. Cycle cranking - Is configurable for the number of starting cycles (1 to 7) and duration of crank and rest periods. Control includes starter protection algorithms to prevent the operator from specifying a starting sequence that might be damaging. Time delay start and stop (cooldown) - Configurable for time delay of seconds prior to starting after receiving a remote start signal and for time delay of seconds prior to shut down after signal to stop in normal operation modes. Default for both time delay periods is 0 seconds. Alternator control The control includes an integrated three phase line-toline sensing voltage regulation system that is compatible with shunt or PMG excitation systems. The voltage regulation system is a three phase full wave rectified and has an FET output for good motor starting capability. Major system features include: Digital output voltage regulation - Capable of regulating output voltage to within +/-1.0% for any loads between no load and full load. Voltage drift will not exceed +/- 1.5% for a 40 ºC (104 ºF) change in temperature in an eight hour period. On engine starting or sudden load acceptance, voltage is controlled to a maximum of 5% overshoot over nominal level. The automatic voltage regulator feature can be disabled to allow the use of an external voltage regulator. Droop voltage regulation - Control can be adjusted to droop from 0-10% from no load to full load. Torque-matched V/Hz overload control - The voltage roll-off set point and rate of decay (i.e. the slope of the V/Hz curve) is adjustable in the control. Fault current regulation - PowerCommand will regulate the output current on any phase to a maximum of three times rated current under fault conditions for both single phase and three phase faults. In conjunction with a permanent magnet generator, it will provide three times rated current on all phases for motor starting and short circuit coordination purpose. Protective functions On operation of a protective function the control will indicate a fault by illuminating the appropriate status LED on the HMI, as well as display the fault code and fault description on the LCD. The nature of the fault and time of occurrence are logged in the control. The service manual and InPower service tool provide service keys and procedures based on the service codes provided. Protective functions include: Battle short mode When enabled and the battle short switch is active, the control will allow some shutdown faults to be bypassed. If a bypassed shutdown fault occurs, the fault code and Our energy working for you Cummins Power Generation Inc.All rights reservedspecifications subject to change without noticecummins Power Generation and Cummins are registered trademarks of Cummins Inc.

324 description will still be annunciated, but the genset will not shutdown. This will be followed by a fail to shutdown fault. Emergency stop shutdowns and others that are critical for proper operation are not bypassed. Please refer to the Control Application Guide or Manual for list of these faults. Derate The Derate function reduces output power of the genset in response to a fault condition. If a derate command occurs while operating on an isolated bus, the control will issue commands to reduce the load on the genset via contact closures or Modbus. Configurable alarm and status inputs The control accepts up to four alarm or status inputs (configurable contact closed to ground or open) to indicate a configurable (customer-specified) condition. The control is programmable for warning, shutdown or status indication and for labeling the input. Emergency stop Annunciated whenever either emergency stop signal is received from external switch. Full authority electronic engine protection Engine fault detection is handled inside the engine ECM. Fault information is communicated via the SAE-J1939 data link for annunciation in the HMI. General engine protection Low and high battery voltage warning - Indicates status of battery charging system (failure) by continuously monitoring battery voltage. Weak battery warning - The control system will test the battery each time the generator set is signaled to start and indicate a warning if the battery indicates impending failure. Fail to start (overcrank) shutdown - The control system will indicate a fault if the generator set fails to start by the completion of the engine crack sequence. Fail to crank shutdown - Control has signaled starter to crank engine but engine does not rotate. Cranking lockout - The control will not allow the starter to attempt to engage or to crank the engine when the engine is rotating. Alternator protection AmpSentry Protective relay - A UL Listed comprehensive monitoring and control system integral to the PowerCommand Control System that guards the electrical integrity of the alternator and power system by providing protection against a wide array of fault conditions in the generator set or in the load. It also provides single and three phase fault current regulation so that downstream protective devices have the maximum current available to quickly clear fault conditions without subjecting the alternator to potentially catastrophic failure conditions.

These figures already include an allowance for charger variations (they are 80% of the typical trip-point) and are for the complete circuit: total of battery leads, battery's internal resistance, and any external equipment. The total resistance seen by the charger must not exceed the following values: TABLE 1 12V 24V Maximum Resistance 58m 116m D. To determine the appropriate cable and length, please refer to the following table: Wire Size Resistance per Foot TABLE 2 Maximum Charger to Battery Distance (Ft.) Recommended Charger to Battery Distance (Ft.) AWG mm 2 m/ft. 12V 24V 12V 24V The above lengths consider the resistance of the battery and cables only and do not take into account any additional interconnects. The above lengths are for operation at 25C. For high temperature installations (40C) reduce lengths by 10%. In the case of high resistance in the cables to the battery the charger may cycle between AC Fail and Battery Fault LEDs (approximately every 10 seconds). Cable runs exceeding the proper length for the cable gauge used most often cause this problem. The appropriate solution is to change the cable gauge to properly correspond with the necessary cable length (see TABLE 2). In some cases where the resistance is not too far above maximum, the charger may recover after some time (approximately 10 minutes) and start charging the batteries. If it is not possible to decrease the system resistance the Battery Fault feature can be disabled. Please contact SENS at for further information. E.

355 PowerCommand Annunciator Discrete Input or PCCNet Description The Universal Annunciator Module provides visual and audible indication of up to 20 separate alarm or status conditions, based on discrete (relay) inputs or network inputs. Each LED can be controlled by either a discrete wire input or by a signal on the PCCNet network sent from an external device, such as a PCC1301 or PCC2100 (version 2.4 or later) control. In addition to the LEDs, the annunciator can control four custom relays based on signals received over the PCCNet. When one of the annunciator s discrete inputs is activated, the annunciator will broadcast that information over the network. By taking advantage of the network, discrete inputs and custom relays, the annunciator can be used as expanded I/O for a genset controller. Easily installed in a location to give immediate notification of an alarm or warning status. Designed to give operating/monitoring personnel quick-glance status information. The module directly senses battery voltage to provide green/yellow/red alarm and status information for that parameter. Genset controller complies with NFPA level two requirements when used with the display but without the annunciator panel. When used with the annunciator it meets NFPA level one requirements (emergency and standby power systems). The annunciator module can also be used for monitoring of transfer switch or other equipment status. Features Visual and audible warnings of up to 20 separate alarm or status conditions. LEDs can be controlled either via PCCNet or discrete input. Status of discrete inputs is broadcast on network. Four custom relays can be controlled over the PCCNet network. Configurable LED color (red, yellow or green) and selectable horn operation allows maximum flexibility. Standard NFPA 110 label, field configurable for other alarm status and conditions. Each audible alarm is annunciated, regardless of the number of existing alarm conditions displayed. Sealed membrane panel design provides environmental protection for internal components and is easy to clean. Configurable for negative (ground) input or positive input. Integral DC voltage sensing.

364 Transfer switch mechanism Specifications Voltage rating Arc interruption Neutral bar Auxiliary contacts Our energy working for you. Transfer switch mechanism is electrically operated and mechanically held in the Source 1 and Source 2 positions. The transfer switch incorporates electrical and mechanical interlocks to prevent inadvertent interconnection of the sources. Independent break-before-make action is used for both 3-pole and 4-pole/ switched neutral switches. This design allows use of sync check operation when required, or control of the operating speed of the transfer switch for proper transfer of motor and rectifier-based loads (programmed transition feature). True 4-pole switching allows for proper ground (earth) fault sensing and consistent, reliable operation for the life of the transfer switch. The neutral poles of the transfer switch have the same ratings as the phase poles and are operated by a common crossbar mechanism, eliminating the possibility of incorrect neutral operation at any point in the operating cycle, or due to failure of a neutral operator. High pressure silver alloy contacts resist burning and pitting. Separate arcing surfaces further protect the main contacts. Contact wear is reduced by multiple leaf arc chutes that cool and quench the arcs. Barriers separate the phases to prevent interphase flashover. A transparent protective cover allows visual inspection while inhibiting inadvertent contact with energized components. Switch mechanism, including contact assemblies, is third party certified to verify suitability for applications requiring high endurance switching capability for the life of the transfer switch. Withstand and closing ratings are validated using the same set of contacts, further demonstrating the robust nature of the design. 600 VAC, 50 or 60 Hz. Multiple leaf arc chutes provide dependable arc interruption. Operating temperature -40 F (-40 C) to 140 F (60 C) Storage temperature -40 F (-40 C) to 140 F (60 C) Humidity Altitude Surge withstand ratings Total transfer time (sourceto-source) Manual operation handles A full current-rated neutral bar with lugs is standard on enclosed 3-pole transfer switches. Two isolated contacts (one for each source) indicating switch position are provided for customer use. Contacts are normally open, and close to indicate connection to the source. Wired to terminal block for easy access. Rated at 10 amps continuous and 250 VAC maximum. UL recognized, and CSA-certified. Up to 95% relative, non-condensing Up to 10,000 ft (3,000 m) without derating Voltage surge performance and testing in compliance with the requirements of IEEE C62.41 (Category B3) and IEEE C Will not exceed 6 cycles at 60 Hz with normal voltage applied to the actuator and without programmed transition enabled. Transfer switches rated through 1000 amps are equipped with permanently attached operating handles and quick-break, quick-make contact mechanisms suitable for manual operation. Transfer switches over 1000 amps are equipped with manual operators. All switches must be de-energized before manual operation is attempted. Transition modes Open transition/programmed: Controls the time required for the device to switch from source to source, so that the load-generated voltages decay to a safe level before connecting to an energized source. Recommended by NEMA MG- 1 to prevent nuisance-tripping breakers and load damage. Adjustable 0-60 seconds, default 0 seconds. Programmed transition is standard on amp switches, and optional on amps. Open transition/in-phase: Initiates open transition transfer when in-phase monitor senses both sources are in phase. Operates in a break-before-make sequence. Includes ability to enable programmed transition as a back-up. If sources are not in phase within 120 seconds, switches from amps will transfer using programmed transition (not available on open transition switches over 1200 amps). Closed transition: Used in applications where loads are sensitive to the momentary power interruption that occurs when performing open transition between sources. Closed transition is accomplished by briefly (<100 msec) paralleling two good sources to eliminate the momentary break in the power supply. Closed transition is only available as an option on OTPC models from amps. Genset-to-genset: Either genset can be designated as the lead genset. If the lead genset goes down or is taken offline, the transfer switch starts the second genset and transfers the load. The control can be programmed to alternate between the two gensets at a set interval up to 336 hours (2 weeks) Cummins Power Generation Inc. All rights reserved.
