14 2.6 Inspection Once all wiring is complete, verify that: 1. All wiring is installed. 2. Excess screws, metal filings and wire clippings are removed from inside the unit(s). 3. Screws and fasteners are securely tightened. 4. Exposed wiring has no contact with other wiring or terminals. 2.7 Checking Motor Rotation Before attempting a trial operation of the electronic bypass package, ensure that the enclosure door is securely closed. Also, ensure all personnel are clear of the connected load as this operation will energize and rotate the motor. After applying 3 phase power to the electronic bypass package, ensure that the MAIN POWER LED is illuminated. If any alarms are illuminated, refer to Section 6 for explanation. There is no standard for the rotational direction of an induction motor based on the motor lead markings. This, plus the uncertainty of the phase rotation of the utility power being applied to the electronic bypass package terminals, requires that the motor rotation direction be checked and be correct in both VFD and Bypass Modes. Failure to confirm rotation may cause severe damage to the electronic bypass package, motor or the driven equipment Check #1: Rotation on VFD power WARNING Place the VFD package in Hand (local) Mode control by pressing the VFD and HAND push buttons on the electronic bypass keypad. The VFD, HAND, INPUT and OUTPUT CONTACTOR LEDs will be illuminated. The VFD must be started and stopped by the START/STOP buttons on the VFD keypad. Use the up arrow on the VFD keypad to increase the speed reference of the VFD or the down arrow on the VFD keypad to decrease the speed reference of the VFD. Note the direction of rotation as the motor shaft begins to rotate as compared to the required rotation direction. To stop the VFD, press the OFF/RESET push button. 14 Electronic Bypass Controller Installation and Commissioning Guide

Motor Rotation Correction VFD Correct Correct Incorrect Incorrect Bypass Correct Incorrect Correct Incorrect Action. No Action. Change any two power leads at input disconnect. Change any two leads at input at input disconnect, and change any two leads at the output of the motor overload. Change any two leads at output of motor overload. There is no standard for the rotational direction of an induction motor based on the motor lead markings. This, plus the uncertainty of the phase rotation of the utility power being applied to the electronic bypass package terminals, requires that the motor rotation direction be checked and be correct in both VFD and Bypass Modes. Failure to confirm rotation may cause severe damage to the electronic bypass package, motor or the driven equipment. Electronic Bypass Controller Installation and Commissioning Guide 15

16 Section 3 - Operation Precautions: 1. Motor rotation MUST be checked in both VFD and Bypass Modes. Failure to confirm rotation may cause severe damage to the electronic bypass, motor or its driven equipment. 2. Only turn ON the input power supply after closing the front door. 3. DO NOT touch the VFD heatsink which operates at a very high temperature. 4. Since it is easy to change operation from low to high speed, verify the safe working range of the motor and connected load before operation. 5. DO NOT check signals during operation. 6. VFD parameters have been factory set for operation in the electronic bypass package. DO NOT change these settings, as this will result in improper operation. Failure to observe these precautions may result in equipment damage, serious personal injury or death. 3.1 Keypad Operation WARNING The electronic bypass package utilizes two keypads in its operation. The VFD keypad controls the speed in the Hand Mode using the up and down arrow keys. In Auto Mode, the user-supplied 4 20 ma speed reference is connected to speed reference input (M200 terminals 4-6, M400 terminals 5-6, H300 terminals 6 9).

22 Section 4 Overview of the electronic bypass All start/stop, safety, and fire alarm inputs are routed to the electronic bypass control board via customer terminal connections. The VFD analog output is directly connected to the VFD control terminals. The electronic bypass control card is factory set to accept a sinking type (dry contact closure) type input. The analog input is factory set to accept a 4 20 ma speed reference signal. All control wiring must be run in a separate conduit from ANY high voltage or power wiring. The wiring should also be properly grounded and shielded when necessary to ensure proper operation. 4.1 Control Board The following sections describe the electronic bypass control board DIP switch and jumper settings required to properly configure the electronic bypass. All jumpers and switches are located on the door mounted control board. 1. Option Enable/Disable (SW1) 2. Digital Inputs (J13) 3. Digital Outputs (J14) 4. Relay Outputs (J12) 4.2 Electronic Bypass Keypad Function Summary (refer to table on next page) The electronic bypass keypad has (6) buttons labeled TEST, VFD, BYPASS, HAND, AUTO, and OFF/RESET. Each button has an associated LED that indicates the state of that button s function. In addition, the keypad contains four alarm LEDs which indicate Motor Overload, External Safety, Fire Alarm and VFD Fault. The left-hand side of the keypad represents the bypass schematically, using 5 LEDS to indicate Power ON, Input Contactor (closed), Bypass Contactor (closed), Output Contactor (closed) and VFD enabled. Finally, a RUN LED located between the HAND and AUTO buttons gives an indication that the motor is running. 22 Electronic Bypass Controller Installation and Commissioning Guide

24 4.3 Using the Electronic Bypass Configuration Switches The bypass configuration switches are a group of four switches that are used to tailor the following: O N Automatic Bypass Fire Alarm Damper Control Fireman s Override Note: ON disables function Switch 1: Enables or disables the automatic bypass function. With switch 1 in the ON position and the electronic bypass package operating in VFD Mode, a VFD fault will cause both the operation and run modes to be canceled (stopping the motor) and the VFD FAULT LED to illuminate in the Alarm Display. With switch 1 in the OFF position, a VFD fault will cause the bypass contactor to close, keeping the motor running on line power. As with the switch 1 ON configuration, the drive fault will be displayed in the Alarm Display. See section Switch 2: Controls the bypass response to a fire alarm condition. The OFF (active) position equals Purge ; the ON position equals an All Stop position. The default ON position of switch 2 causes the opening of the fire alarm input (TB2-6) to stop the motor independent of whether it was being run by the VFD or the line. When the motor is stopped in this situation, the previous operating state of the electronic bypass package will be restored by removing the fire alarm signal and cycling the customer reset input. It is recommended that VFD parameter Catch a Spinning Motor, be set to 1 if the fire alarm input is used. With switch 2 in the active OFF position, the bypass will attempt to run the system to destruction in the event of fire. Receiving a fire alarm signal in this mode will force the unit to bypass, causing the motor to operate off the AC line. The motor cannot be stopped locally or by external contacts in this mode. The keypad will appear to be locked out. Only cycling power to the bypass will return it to normal operation. Switch 3: Used in damper applications where it is required to make sure a damper has opened in order to run the motor. The default ON position of Damper Control (switch 3) disables damper mode. With the Damper Mode set in the enabled OFF position, when the motor is told to start (either on the VFD or by the bypass from the AC line) a 120 second timer is started. The bypass controller must see the customer 24 Electronic Bypass Controller Installation and Commissioning Guide

25 damper feedback contact closed (TB3-3) within that time to prevent the bypass controller from faulting and preventing motor operation. The bypass keypad will annunciate the faulted condition by flashing one or more of the button status LEDs that happened to be on at the time of the fault. The bypass controller can be reset by cycling the customer reset input, which will reset the 120 second timer and retry motor operation. Should the damper open initially, but sometime during operation the damper feedback is lost, the electronic bypass package will trip, stopping the motor. Switch 4: With the VFD and AUTO pushbuttons pressed on the bypass keypad, Fire Alarm (switch 2) and Fireman s Override (switch 4) OFF, upon opening the fire alarm input (TB2-6) the unit goes into Bypass Mode and the bypass keypad will indicate a Fire Alarm. A VFD fault will occur and the input contactor will drop out. Upon closing the fireman s override input (TB3-4), the unit will go to Bypass and Hand Mode. Re-closing the fire alarm input and then opening the fireman s override input (TB3-4) will put the package back into VFD + Auto Mode. With Damper Control (switch 3) OFF: For normal operation mode, a start command is given, closing the Damper relay contacts. The unit then waits for a contact closure from the customer-supplied Damper End switch indicating the damper is fully open. If the damper feedback does not occur within 120 seconds, then one or more of the LEDs on the board will begin to flash indicating the Damper Close Timer has timed out without feedback being received. In Fireman s Override Mode, if the fireman s override is enabled along with the Damper Control, at the end of the 120 seconds if there is no feedback from the Damper End switch, the unit goes into bypass and operates as described above. 4.4 Using the Additional Customer Inputs In addition to the inputs described in the preceding sections, there are three other customer inputs for use in specific applications. Safety input (TB2-3): is normally closed. Opening it causes the motor to stop under all conditions and will lock out all requests to start the motor. A LED in the Alarm Display annunciates the status of the safety input. If there are no safeties, a jumper must be installed between TB-s-3 and TB-2-8 to allow operation. To reset the electronic bypass package from a safety trip, the safety interlock must be re-closed and the customer reset input (TB2-4) or the bypass keypad OFF/RESET button must be cycled. Electronic Bypass Controller Installation and Commissioning Guide 25

26 Remote bypass input (TB3-1): can be used to override the keypad selections and force the electronic bypass into Bypass Mode from an external contact. Once this signal is removed, the electronic bypass will not return to its previous mode of operation without keypad interaction. Remote VFD input (TB3-2): works just like the remote bypass input by forcing the electronic bypass into VFD Mode. The electronic bypass will not return to its previous mode when the signal is removed. 4.5 Motor Overload Motor Overload is generated by the overload relay built into the electronic bypass. Should this relay operate, the motor will stop independent of its mode of operation. The motor cannot be restarted while the MOTOR OVERLOAD indicator is illuminated. Once the relay is reset, operation can be restored by reselecting a run mode from the keypad. 4.6 Failure and Power Off Conditions Should the electronic bypass control card fail such that it cannot process inputs, the control card has an alternative mechanism for controlling the bypass contactor. Jumpers J5, J6, and J7 control the input, bypass and output contactors respectively. Moving any of these jumpers from the default open position to the emergency position will force the associated contactor to be energized. This will happen irrespective to any logic damage on the bypass board. See section for details. An interlock prevents the closing of the 3 contactors at once. In the event the bypass control board should lose power, its EEPROM memory retains the last operating configuration, which is restored on the next power-up. 4.7 Control Modes of the Electronic Bypass When power is initially applied, the green main POWER ON LED is illuminated and will remain on as long as power is connected. The OFF/RESET will be the only other LED illuminated. The input contactor remains OFF. The VFD will have no power and its display will remain blank. A VFD or bypass mode must first be selected, followed by a command in Start Auto or Hand Mode TEST mode In Test Mode the functionality of the VFD, external speed reference devices, and system setup characteristics can be read, set and modified. In Test Mode the input contactor is energized. Note that the Test Mode and Bypass Mode can be operated simultaneously if desired. To place the VFD package in Test Mode, press the TEST button. The TEST and INPUT CONTACTOR LEDs will be illuminated. 26 Electronic Bypass Controller Installation and Commissioning Guide

27 To exit the Test Mode, press the OFF/RESET button on the electronic bypass keypad. The VFD input contactor will open and the TEST and INPUT CONTACTOR LEDs will go out VFD mode In VFD Mode both the input and output contactors are energized. A Start command must exist before the VFD can operate. To place the VFD package in VFD Mode, press the VFD pushbutton. The VFD, INPUT and OUTPUT CONTACTOR LEDs will be illuminated. To exit the VFD Mode, press the OFF/RESET button on the electronic bypass keypad. The VFD, input and output contactor will open and their respective keypad LEDs will go out Bypass Mode In Bypass Mode the bypass contactor will be energized. A Start command must exist before the bypass contactor will close. To place the VFD package in Bypass Mode, press the BYPASS pushbutton. The BYPASS LED will be illuminated. Note that the Bypass Mode and Test Mode can be operated simultaneously if desired. To exit the Bypass Mode, press the OFF/RESET button on the electronic bypass keypad. The bypass contactor will open and its respective keypad LED will go out Hand Mode In the Hand Mode, starting and stopping is controlled entirely from the drive keypad. Hand Mode can control both VFD and Bypass operation modes. To place in VFD Hand Mode, press the VFD button. Then press the HAND button. The VFD, HAND, INPUT and OUTPUT CONTACTOR and RUN LEDs will be illuminated. Pressing the HAND button also creates an enable command for the VFD. The VFD must be started and stopped by the START/STOP buttons on the VFD keypad. Motor speed is controlled by the up and down arrow buttons on the VFD keypad. To place in Bypass Hand Mode, press the BYPASS button. Then press the HAND button. The BYPASS, HAND, BYPASS CONTACTOR and RUN LEDs will be illuminated. To exit the Hand Mode, press the OFF/RESET button once on the electronic bypass keypad. The HAND and RUN LEDs will turn off. Press the OFF/RESET button again and it will turn off either the VFD or BYPASS LEDs and open the respective contactors. Electronic Bypass Controller Installation and Commissioning Guide 27

28 4.7.5 Auto Mode In the VFD Auto (automatic) mode, a building automation system or other external device is required to supply start/stop and speed reference information to the electronic bypass package. During Auto Mode operation, the electronic bypass keypad remains enabled for stopping, operation mode and bypass selection functions. Auto Mode can control both VFD and bypass operation modes. To place in Auto Mode, press the VFD button. Then press the AUTO button. The VFD, AUTO and INPUT and OUTPUT CONTACTOR LEDs will be illuminated. The RUN LED will not illuminate until the user-supplied (TB2-5) run contact closes. Motor speed is controlled by the user-supplied 4 20 ma reference signal. See section 4.3 and 4.4 if a 0 10 Vdc reference is to be used. To place in Bypass Auto Mode, press the BYPASS button. Then press the AUTO button. The BYPASS and AUTO LEDs will be illuminated. The bypass contactor and RUN LEDs will not illuminate until the user supplied (TB2-5) run contact closes. To exit the Auto Mode, press the OFF/RESET button once on the electronic bypass keypad. The AUTO and RUN LEDs will turn off. Pressing the OFF/RESET button again will turn off the VFD or BYPASS operation LEDs. 4.8 Bypass Modes of the Electronic Bypass There are three modes of operation for bypassing the VFD and operating on full line power: 1. MANUAL Bypass - Manual bypass operation 2. AUTOMATIC Bypass - Automatic bypass on VFD fault 3. EMERGENCY bypass - Emergency, manual bypass MANUAL Bypass In the Manual Bypass Mode, the motor begins bypass operation immediately upon selecting Hand Mode or upon the user-supplied contact closure in Auto Mode. The motor will stay in bypass until the user chooses to leave either Hand or Auto Mode. Bypass is also available while in the Test Mode of operation. To place in Manual Bypass Mode, press the BYPASS button. When the BYPASS LED illuminates, press either the HAND or AUTO button. When the HAND button is pressed the bypass contactor will energize and the motor will immediately start across the line. When the AUTO button is pressed, the bypass contactor will not energize until the user-supplied (TB2-5) run contact is closed. The bypass contactor will then energize and the motor will immediately start across the line. To exit the Bypass Mode, Press the OFF/RESET button on the electronic bypass keypad. 28 Electronic Bypass Controller Installation and Commissioning Guide

29 4.8.2 Automatic Bypass on VFD Fault In the Automatic Bypass on VFD Fault Mode of operation, when the electronic bypass control board senses a VFD fault it will automatically switch the motor to Bypass operation. This function is enabled by DIP switch 1, position 1, placed in the OFF position. Automatic Bypass will operate in both the VFD Auto and the VFD Hand Modes of operation. The functionality in each mode is exactly the same. CAUTION: Use caution when selecting this mode as the motor will accelerate to full speed anytime the VFD experiences any type of fault condition Emergency Bypass In the unlikely event of a failure of the electronic bypass control board, an emergency bypass jumper may be repositioned to enable the electronic bypass to be operated as a full voltage fixed speed starter. The emergency bypass jumper is located on the component side of the door-mounted control board. To change this jumper, use the door interlocked disconnects to remove power from the electronic bypass before opening the enclosure door. Remove the four (4) mounting screws from the control board. With the component side facing you, move jumper J6 from the open position (normal) to the emergency position. When the enclosure door is closed and the disconnect is in the ON position, the bypass contactor coil will be immediately energized closing the contactor and starting the motor at full across-the-line voltage. The motor thermal overload protection is disconnected in this mode. To exit Emergency Bypass, turn the door interlocked disconnect to the OFF position. Power to the bypass contactor coil will be removed and the contactor will open disconnecting the motor. Remove the control board from the door and move jumper J6 from the emergency position to the open position. Close the enclosure door and place the door interlock in the ON position. Control will be returned to the control board for VFD or bypass operation. When in Emergency bypass mode the motor thermal overload relay is disconnected and will not protect the motor from an overload condition. Damage to the motor may occur.
