38 Ekip Dip protection trip unit ABB SACE Emax Operator interface Introduction The operator interface of the Ekip Dip protection trip unit allows you to: Set the parameters relating to the available protections. View the status of the trip unit and alarms. Connect to the frontal connector to communicate and perform the opening test. Components of the interface The Ekip Dip operator interface appears as follows: Figure 75 The following table provides a description of the components of the interface: Position Type Description A L Protection LED (alarm and trip) B L Protection LED (pre-alarm) C S Protection LED (alarm and trip) LED D I Protection LED (trip) E G Protection LED (alarm and trip) F Power-on LED (trip unit powered and on) G L Protection dip-switch (threshold I1) H Protections: S Protection dip-switch (threshold I2) I thresholds I Protection dip-switch (threshold I3) L G Protection dip-switch (threshold I4) M L Protection dip-switch (time t1) N Protections: times S Protection dip-switch (time t2 and type of curve) Or G Protection dip-switch (time t4 and type of curve) P Settings Neutral and frequency dip-switch Q Test pushbutton Test R Test connector IMPORTANT: the figure above refers to an Ekip Dip, LSIG version. In the case of Ekip Dip LI or LSI versions, LEDs and dip-switches related only to the protections present are available ABB 1SDH001000R ECN Rev. B Ekip Dip protection trip unit 1 - Operator interface

39 LEDs The LEDs are useful on Ekip Dip in order to distinguish and identify various types of information on the protection trip unit, the circuit-breaker and state of the line currents. Operational conditions The operation of the LED is determined by the power supply conditions of the trip unit: With the trip unit energized (by current sensors or by auxiliary power supply or by Ekip TT or by Ekip T&P or by Ekip Bluetooth) the LEDs are operational for all the signals. With the trip unit de-energized, the LEDs are limited to the signalling of the last switch-off or trip event (combined with the check via itest, described below). NOTE: with the trip unit off, the operation of the LEDs is guaranteed if the internal battery of the trip unit is working properly. About The LEDs combined with the protections provide various information, through different combinations of lighting and blinking. NOTE: all the combinations related to protection LED signals are described in chapter Selfdiagnosis and signalling, on page 48. The power-on LED provides information about the power status of the protection trip unit: LED on (default configuration) fixed or blinking, signals trip unit energized. LED off signals trip unit de-energized. NOTE: with Ekip T&P and Ekip Bluetooth modules and Ekip Connect software, it is possible to configure how the power LED functions (LED fixed or blinking). Protections: thresholds The thresholds of all the protections can be modified with various dip-switches, as specified on the serigraph of the interface. The values of the protections make reference to the current In, a nominal value of the trip unit defined by the Rating Plug. IMPORTANT: Modification of the thresholds must be performed in the absence of protection alarms. Modifications carried out in alarm conditions are accepted by the trip unit when resting condition is restored (absence of protection alarms). Protections: times The times and the curves of the protections can be modified with various dip-switches, as specified on the serigraph of the interface. IMPORTANT: Modification of the times must be performed in the absence of protection alarms. Modifications carried out in alarm conditions are accepted by the trip unit when resting condition is restored (absence of protection alarms). Settings Two further settings are available: Neutral allows activation and adjustment of the protections on the neutral pole. Frequency allows the selection of the installation frequency ABB 1SDH001000R ECN Rev. B Ekip Dip protection trip unit 1 - Operator interface

40 itest pushbutton The itest pushbutton is useful for three operations: Perform tests (circuit-breaker opening test and LED test). Reset the signal for intervention of the protection as a result of a trip. With the trip unit off, check the information relating to the switch-off or tripping event. NOTE: with the trip unit off, pressing of the itest button switches on (for approximately 4 seconds): the power-on LED, if the trip unit is off due to an energy drop (primary current less than the minimum level of operation, removal of auxiliary power supply with circuit-breaker open, etc ). the protection tripped LED if the trip unit is off due to a protection trip. Test connector The test connector allows the connection of Ekip TT, Ekip T&P and Ekip Bluetooth modules, in order to perform the following operations: Temporary energizing of the trip unit to check the status, and perform the trip test (option possible with all the front interface modules). Analysis, supervision and setting of additional parameters through external communication test units (Ekip T&P, Ekip Bluetooth) ABB 1SDH001000R ECN Rev.

41 2 - Protections L Protection The L protection protects against overloads NOTE: the protection is available and active for all the versions of the trip unit. t I1 L When the activation threshold is exceeded, the protection trips in a time that decreases as the current read increases. t1 I Parameters All the parameters that can be modified by the user affect the response curve, and related tripping times. Parameter Description The value I1 contributes in calculating the tripping time, and also defines the current value that, if exceeded, activates the protection (with reference to the curve, it is the part parallel to the y-axis). Threshold I1 Time t1 IMPORTANT: The protection is activated and starts timing for currents between 1.05 and 1.2 of the threshold I1 set (1). The delay is interrupted if the current drops below the activation threshold. The value t1 contributes in calculating the tripping time (with reference to the curve, T1 affects the entire curve by shifting it as a whole along the y-axis). IMPORTANT: The protection limits the tripping time to 1 second in two cases: if according to the calculation the time is less than 1 second. If the fault current is greater than 12 In. (1) Example (with I1 set to 400 A): the protection is activated for currents between 420 A and 480 A. With the modules Ekip T&P or Ekip Bluetooth and with the Ekip Connect software, it is possible to activate the function Thermal Memory, and adjust the threshold of Pre-alarm. See page ABB 1SDH001000R ECN Rev. B Ekip Dip protection trip unit 2 - Protections

42 S Protection The S protection protects against the selective short circuit. NOTE: the protection is available for LSI and LSIG versions of the trip unit. t I2 S When the activation threshold is exceeded, the protection trips within a fixed or dynamic time (the time decreases as the current read increases). t2 Parameters All the parameters that can be modified by the user affect the response curve, and related tripping times. I Parameter Enable Type of curve Description By setting the threshold dip-switches to the Off position, the protection is disabled. It determines the dynamic of the curve and the tripping time, fixed or dynamic according to the selection: NOTE: calculation of the tripping time of the inverse time curve is based on a mathematical expression. The details are provided in the table on page 45. It defines the current value that if exceeded activates the protection (with reference to the curve, it is the part parallel to the y-axis). Threshold I2 Time t2 IMPORTANT: The I2 threshold set must be higher than the I1 threshold. An incorrect configuration returns an alarm signal. The delay is interrupted if the current drops below the activation threshold. The selected function determines the contribution of t2: Fixed time: t2 is the delay time between exceeding the I2 threshold and sending the opening command. Dynamic time: t2 contributes in calculating the tripping time (with reference to the curve, t2 affects the entire curve, shifting it as a whole along the vertical axis). IMPORTANT: The minimum tripping time of the protection is t2. If, according to the calculation, the tripping time is less, it is automatically limited to t2. For all the UL versions, the maximum time allowed by the trip unit is 0.4 s. If a higher value is set, the trip unit signals the error and forces the parameter to 0.4 s. With the modules Ekip T&P or Ekip Bluetooth and with the Ekip Connect software, it is possible to activate the function Thermal Memory. See page ABB 1SDH001000R ECN Rev. B Ekip Dip protection trip unit 2 - Protections

43 I Protection The I protection protects against instantaneous short circuit. When the activation threshold is exceeded, the protection trips within a fixed non-adjustable time. t I3 I Parameters The user can set the intervention threshold. t3 I Parameter Enable Threshold I3 Description By setting the threshold dip-switches to the Off position, the protection is disabled. It defines the current value that if exceeded activates the protection (with reference to the curve, it is the part parallel to the y-axis). IMPORTANT: The I3 threshold set must be higher than the I2 threshold. An incorrect configuration returns an alarm signal ABB 1SDH001000R ECN Rev. B Ekip Dip protection trip unit 2 - Protections

44 G Protection The G protection protects against an ground fault. NOTE: the protection is available for the LSIG version of the trip unit. t I4 G When the activation threshold is exceeded, the protection trips within a fixed or dynamic time (the time decreases as the current read increases). t4 Parameters All the parameters that can be modified by the user affect the response curve, and related tripping times. I Parameter Description By setting the dip-switches of the threshold in one of the available combinations other than Off, the protection is enabled. If enabled, the protection is inhibited automatically by the trip unit in two conditions: Disconnection of one or more current sensors. Current measured on one of the phases is higher than a maximum value. Enable Type of curve IMPORTANT: the maximum current value that deactivates G protection varies according to the threshold set: 8 In (with I4 0.8 In) 6 In (with 0.5 In I4 < 0.8 In) 4 In (with 0.2 In I4 < 0.5 In) 2 In (with I4 < 0.2 In) It determines the dynamic of the curve and the tripping time, fixed or dynamic according to the selection: NOTE: calculation of the tripping time of the inverse time curve is based on a mathematical expression. The details are provided in the table on page 45. It defines the current value that if exceeded activates the protection (with reference to the curve, it is the part parallel to the y-axis). Threshold I4 Time t4 IMPORTANT: The delay is interrupted if the current drops below the tripping threshold. For all the UL versions the maximum threshold allowed by the trip unit is 1200 A. If a higher value is set, the trip unit signals the error and forces the parameter to 1200 A. The selected function determines the contribution of t4: Fixed time: t4 is the delay time between the exceeding of the I4 threshold and the sending of the opening command. Dynamic time: t4 contributes in calculating the tripping time (with reference to the curve, t4 affects the entire curve, shifting it as a whole along the y-axis). IMPORTANT: The minimum tripping time of the protection is t4. If, according to the calculation, the tripping time is less, it is automatically limited to t4. For all the UL versions, the maximum time allowed by the trip unit is 0.4s. If a higher value is set, the trip unit signals the error and forces the parameter to 0.4 s. With the Ekip T&P or Ekip Bluetooth modules and with the Ekip Connect software, it is possible to adjust the threshold of Pre-alarm. See page ABB 1SDH001000R ECN Rev. B Ekip Dip protection trip unit 2 - Protections

45 Neutral and frequency Adjusting of the neutral setting is used to customize the L, S and I protections on the Neutral pole with a control factor different to the other phases. NOTE: use the adjustment of the neutral setting only with four-pole or three-pole circuitbreakers with external neutral: with three-pole circuit-breakers and neutral protection active, the trip unit signals the absence of the current sensor. The adjustment of the frequency is used in order to set the installation frequency (between 50 and 60 Hz). Neutral parameters The user can activate the protection and set the percentage for calculation of the protection thresholds. Parameter Enable Threshold InN Description By setting the threshold dip-switches to the Off position, the protection on the Neutral is disabled. It establishes the multiplication factor applied to the trip thresholds of the protections: 50%: lowest trip thresholds for the neutral current. 100%: same trip thresholds for all poles. 200%: highest trip thresholds for the neutral current. Limitations The adjustment of the Neutral threshold to value of 200 % must be performed considering the following formula: (I1 * InN) Iu. I1 indicates the threshold of protection L in Amperes (example: In = 1000 A; I1 = 0.45 In = 450 A), InN is the neutral threshold expressed as a multiplication factor (example: 2), Iu indicates the size of the circuit-breaker (example: 1000 A) ABB 1SDH001000R ECN Rev. B Ekip Dip protection trip unit 2 - Protections

46 Additional protections The Ekip T&P and Ekip Bluetooth modules, and the Ekip Connect software, allow you to set some protections not available via dip-switch: Thermal Memory T Protection Pre-alarm threshold Hardware Trip Thermal Memory This function, available for protections L and S, reduces the tripping time of the protection based on the time elapsed between multiple trips caused by heating of the cables. IMPORTANT: for the S protection the function can be activated if the selected curve is time-dependent. T Protection The T protection protects the circuit-breaker against abnormal temperatures recorded by the protection trip unit. The T protection is always active; via Ekip Connect it is possible to enable tripping, which takes place for temperatures t < -25 C or t > 85 C. Pre-alarm The purpose of the pre-alarm, available for L and G protections, is to signal that the measured current is near the activation threshold of the protection itself. It is possible to set the pre-alarm threshold in order to establish the pre-alarm activation values; the pre-alarm threshold is expressed as a percentage in relation to the protection thresholds (I1 and I4) and is adjustable between 50% and 90% (default value). Example: with I1 = 0.6 In and pre-alarm threshold L=50 %, the pre-alarm is activated for currents greater than 0.3 In The pre-alarm condition is activated for currents higher than the threshold set, and is deactivated for: Current less than the pre-alarm threshold. Current greater than the activation threshold of protection. Hardware Trip The Hardware Trip protection protects against internal disconnections of the circuit-breaker. Via Ekip Connect it is possible to enable the trip command, which is sent if one or more of the following events is detected: Current sensors disconnected (internal or external if enabled).

53 6 - Ekip Dip: additional functions ABB SACE Emax 2 Ekip T&P, Ekip Programming and Ekip Bluetooth allow the protection trip unit to be connected to Ekip Connect software and to access parameters and commands that cannot be accessed directly from the front interface: a description of the various functions is given below. The additional protections available via Ekip Connect are described on page 44. Maintenance The Maintenance function allows signalling to the user, via LED, that: One year has passed since the last maintenance. Contact wear has increased by more than 10% compared with the value at the last maintenance. Via Ekip Connect there are two selections available: Activation: it allows to the maintenance function to be activated. Reset: it allows confirmation of maintenance on the trip unit; the present date and contact wear values are recorded, and the signal is reset. The reference date is that of the internal clock, and the elapsed time is calculated both with the trip unit on and off (provided that the internal battery is working). NOTE: manual modification of the date can cause variations in the calculation of the time elapsed, and therefore in the date of the next maintenance. NOTE: the maintenance signal due to increased contact wear is active for values higher than 20 %. Local Bus In order to activate communication on the Local Bus with the Ekip Link, Ekip Multimeter or Ekip Signalling 10K modules, the Local Bus parameter must be enabled. NOTE: communication with the modules is active if the auxiliary power supply is present. Date and time The Ekip Dip trip unit has a user-adjustable internal clock. Setting the date can be useful for some functions such as the recording of trips and minimum and maximum currents, and maintenance. The clock is active if the internal battery of the trip unit is working. Programmable States There are sixteen independent programmable states identified by letters A, B, C, D, E, F, G, H, I, L, M, N, O, P, Q, R, allowing different event control solutions to be obtained. The states can be used with the external Ekip Signalling 10K module, on Link Bus or with the programmable functions, to return the desired signalling combination on contacts. Circuit-breaker label and user Data Labels that can be configured by the user so as to facilitate remote identification of the trip unit; in detail CB label, the trip unit model and communication address form the identifier used by Ekip Connect for the devices connected. Info Page Additional information page that can be activated and customized by the user. If activated, it can be accessed on the display by pressing the itest button twice from the main page. NOTE: the pages can be configured with all the trip units for CB SACE Emax 2, but can only be displayed via Ekip Touch. Date of installation Installation date of the circuit-breaker. Load Profile Timers SACE Emax 2 has 4 counters which display how long the maximum current measured has remained in each percentage band. The counters are expressed in seconds and the bands are: 0-49%In, 50-79%In, 80-89%In, >90%In ABB 1SDH001000R ECN Rev. B Ekip Dip protection trip unit 6 - Ekip Dip: additional functions

54 Energy Store Time The counter indicates the time that has elapsed since the last energy metering reset. It is active and updated in the presence of at least one of the following: auxiliary supply, supply by Ekip T&P or supply by Ekip Measuring. Led Alive The parameter allows the behaviour of the power-on LED indicator of the trip unit and of all modules that can be connected to Ekip Supply to be changed. If activated: Trip unit: comes on at a frequency of 0.5 Hz. Modules connected to Ekip Supply: if there are no communication errors, they synchronize with the flashes of the LED on the trip unit. If deactivated, the power-on leds on the respective devices come on with a steady light. Open/Close Remote Direct Command The parameter controls two different command packages for remote circuit-breaker opening and closing: Enabled: commands 7 and 8 are valid (direct commands for CB Open and CB Close). Disabled: commands 7 and 8 are not valid. IMPORTANT: in this case, remote circuit-breaker opening and closing can still be obtained using the programmable YC COMMAND and YO COMMAND functions and the Request circuit-breaker opening (28) and Request circuit-breaker closing (29) commands. Modules network settings retention Allows the communication parameters of the circuit-breaker to be controlled if the trip unit is replaced: Overwrite: the parameters of the new trip unit are valid, so it is advisable to make sure that the communication parameter settings suit the communication network. Keep module data: the new trip unit updates its communication parameters with the ones in the Ekip Com modules of the circuit-breaker, used up to that moment in the various communication networks. The trip units are supplied with the parameter set as Overwrite. Wink The command allows the power-on LED on the protection trip unit to flash at 3 Hz so as to physically identify a trip unit that would not be identifiable in other ways. 3 Hz flashing is disabled by sending another Wink command or by switching off the trip unit. Glitch The commands of Glitch 16 to 23 activate the respective glitch registers, which can be used for customizing programmable functions or output contacts ABB 1SDH001000R ECN Rev.

The network to which the module is to be connected must be dedicated and comprising only Ekip Link and Ethernet switches that declare support for level L2 multicast on the datasheet. In this case the Ethernet switches do not require any configuration. If, instead, the network also includes routers, multicast must be enabled and configured on all VLAN interfaces with level L3. IMPORTANT: the module can be connected only to internal Ethernet networks with one or more switchboards, to which trip units or ABB Emax 2 accessories are connected. It is the installer's responsibility to ensure that all the necessary safety measures are adopted for all the connected devices (for example, the necessary access authorisations, and so on). The module cannot be connected to other Ethernet networks (for example, with the purpose of monitoring the system, or the office), or to the Internet. The module is necessary if you wish to implement these functions: Power Controller Zone Selectivity Programmable Logic For these functions, the trip units of the system that are involved must be equipped with an Ekip Link, and for each of these the IP addresses of the Ekip Link modules of the other trip units must be inserted. Solely with Ekip Dip trip units: the module can also be used with a function similar to that of the Ekip Com Modbus TCP module, but only with the ability to communicate with the ABB master (e.g.: Ekip Connect, or Ekip Control Panel). IMPORTANT: only one Ekip Link can be installed on each circuit-breaker. The modules are always supplied with Ekip AUP and Ekip RTC contacts (see the chapter "6 - Other accessories" on page 70). Compatibility and power supply The module can be installed in the presence of Ekip Dip, Touch, Hi-Touch, G Touch, and G Hi-Touch trip units, and requires the presence of an Ekip Supply module in the first slot of the circuit-breaker terminal box ABB 1SDH001000R ECN Rev.
