Analog inputs

The analog inputs are designed for resistive automotive type sensors like VDO or DATCON. The sensors are connected either by one wire (the second pole is sensor body) or by two wires.
In case of grounded sensors connect the AI COM terminal to the engine body as near from the sensors as possible.
In case of isolated sensors connect the AI COM terminal to the negative power supply terminal of the controller as well as the opposite poles of the sensors.
NOTE:
The fail sensor alarm is issued if the measured resistance is smaller than one half of the first (lowest) point of the sensor curve characteristic or is greater than 112,5% of the last (greatest) point of the sensor curve characteristic.

Configurability

One of the key features of InteliPro unit is high level of flexibility and adaptability of the system to the
particular application. The way how to achieve this is the configuration. Use LiteEdit PC software to
read the configuration from the controller or disk, view it, modify it and write the configuration to controller or disk. To work with InteliPro, LiteEdit version 4.5.2 or higher is necessary. Visit
www.comap.cz
The firmware contains large number of binary inputs and outputs. However, not all functions are required the application, also the controller hardware does not as many input and output terminals. One of main tasks of the configuration is mapping of "logical" firmware input and output signals to the "physical" hardware inputs and outputs.
Configuration parts:
1. Mapping of logical binary inputs (functions) or assigning alarms to physical binary input terminals
2. Mapping of logical binary outputs (functions) to physical binary output terminals
3. Assigning sensor characteristics and alarms to analog inputs
4. Assigning control values and output characteristics to analog outputs
for download or update of this PC application.

5. Selecting of peripherial modules which are connected to the controller and doing the same as above for them
6. Changing language of the unit texts
PRINCIPLE OF BINARY INPUTS AND OUTPUTS CONFIGURATION
The unit is delivered with a default configuration, which should fit to most standard applications.
This default configuration can be changed only using PC and LiteEdit software. See LiteEdit documentation for details.
NOTE:
You need one of communication modules to connect the controller to a PC with LiteEdit. There is a special easy removable service module for cases, where there is no communication module permanently attached.
Once the configuration is modified, it can be stored in a file for later usage with another controller or
for backup purposes. The file is called archive and has file extension "aic". An archive contains full
image of the controller at the moment of saving (if the controller is online to the PC) except firmware, i.e. besides configuration there are also current adjustment of all setpoints, all measured values, copy of history log and copy of alarm list.
The archive can be simply used for cloning of InteliPro units, which means preparing units with
identical configuration and settings.

Introduction

InteliPro protection relay provides high range of flexibility to the users and their applications. In the most common cases, one output for tripping is used. In this case, InteliPro allows provides the common trip output, which represents logical "OR" of all activated and pre-set protective functions of the unit. If needed, InteliPro also allows to operate two circuit breakers, where some protective functions are assigned to one of them and other functions to the other. In such case, the circuit breakers can provide backup for each other, so that in "fail to trip" situation the other circuit breaker opens under pre-set conditions to clear the first breaker failure. Furthermore, InteliPro provides two independent blocking inputs, which can be used to activate or deactivate any of the protective functions of the unit. All necessary inputs and outputs can be freely configured to any input or output of the unit. In case of outputs, any of the 2 relay outputs or 8 open­collector outputs can be selected. In case that any of the configured protective functions is activated, InteliPro relay provides a Trip signal. This signal is provided in both positive and negative logic in order to follow the requirements of the application:
Due to increased safety requirements, some protective relays require that negative logic is used, assuring that loss off power supply always causes the relay to trip. I.e. the relay contacts are used, with fault-free position maintained in energized state. In case of power supply fail, the unit goes to “fault” indication position. The outputs using negative logic are marked with exclamation mark "!" as the first character of their name.
In some applications, the negative logic is not a required functionality. The function of opening the circuit breaker in case of loss of power supply is not accepted as a safety point and the safety is assured by different means e.g. in the superior system or within the protection relays intertripping scheme. In such case, the outputs with positive logic (without the exclamation mark) can be used to signal the detected failure state.
In any case, it must be assured that the InteliPro relay has full control at opening the appropriate breaker by the trip command - i.e. in case of Trip state the unit receives the appropriate CB feedback, confirming its open position. The feedback must repond within preset time to the trip command. A special attention should be paid to opening of motorized circuit breakers, as it could take more than 2s on some types. In such cases it is necessary to use undervoltage coil for fast opening.

Operation mode with 1 common trip output

This is the essential mode of operation of the protection relay InteliPro. In this case, CB1 circuit breaker or contactor is considered as the main connection device, protected by InteliPro. In the ComAp controllers, this breaker is called "Mains Circuit Breaker" = MCB.
Second circuit breaker or contactor is not expected in the protection scheme, but there is still possibility to use the "backup trip" signal from InteliPro relay to operate any backup device, if present on the installation. As such device may be considered another circuit breaker in the line of mains-connection, CB1 undervoltage coil, or any device which serves as a backup in case of the CB1 fail.
The Comm Trp (or !Comm Trp) output is used as the main signal to open the CB1 circuit breaker. InteliPro expects that in such case, the CB1 Feedback input deactivates as a result of the protection trip. Adjustable delay can be set by the setpoint General: BackupTrp Del, to provide backup functionality for the CB1 breaker. If the feedback does not deactivate within this delay, the output Bak Comm Trp activates (or !Bak Comm Trp deactivates) immediately.
An function, which is activated and not blocked within the InteliPro unit activated the Comm Trp signal. Use the blocking inputs to control which protective functions will be used under the appropriate circumstances.

Operation mode with 2 trip outputs

In some cases, the protection relay is requested to operate two circuit breakers. Usually, one of them is considered as the main circuit breaker, with most of the functions configured to operate this cicrcuit breaker. As mentioned above, this breaker often corresponds to the "Mains Circuit Breaker" = MCB as used in ComAp controllers.
The second circuit breaker can be from the point of view of the protection relay considered as a supplementary connection device in the power connection scheme. It can provide back-up functionality in case that the CB1 does not trip on command, or can be operated individually by selected protective functions. It can, but does not necessarily have to correspond to the "Generator Circuit breaker" = GCB as used in the ComAp controllers applications. In such case, e.g. NVD function is the most often case, when GCB (CB2) is tripped instead of MCB (CB1).
In case that 2 circuit breakers are controled by InteliPro unit, it is possible to freely assign, swap or configure the functionalities of both circuit breakers and provide appropriate back-up function of the breakers by the "Priority switching" functionality. It is not practical to use the Comm Trp output in this case. To distinguish between the 2 breakers, outputs Trip 1 and Trip 2 are available.
For each protective function in InteliPro, it is possible to assign either Trip 1 or Trip 2 function, none of them, or both. The setpoint xxx Trp BO in the appropriate group of protection setting is used for this assignment. By this setting, the output Trip 1 or 2 will then contain only those functions which were assigned to it.
Trip 1 output is internally interconnected with CB1 operation, i.e. in case of activation of Trip 1, the CB1 feedback is expected to deactivate. The same applies for Trip 2: in case of activation of Trip 2, the CB2 feedback is expected to deactivate.

Priority switching

Priority switching feature allows using the circuit breakers CB1 and CB2 as a backup to the other one. To clearly understand this, it is necessary first to understand the possibility of assignment of any of the operated two circuit breakers to the appropriate protective function (see the chapter Operation mode with 2 trip outputs). Though both of the breakers are equivalent and fully assignable within the InteliPro relay, the most common application for generator-to-mains connection is as follows:
CB1 is considered as the main connection device of the generator to the mains. In ComAp products, this breaker is called "Mains Circuit Breaker" = MCB.
CB2 is considered as a supplementary connection device on the power connection between generator and mains. There can be specific protection functions assigned the trip CB2 only and it can provide back-up functionality to the CB1. It can, but does not necessarily have to correspond to the "Generator Circuit breaker" = GCB as used in the ComAp products.
As both circuit breakers are equivalent, it is possible to assign CB2 as the main one and CB1 as the backup, or provide a symmetrical backup of both breakers "one to each other".
Depending on setting the setpoint General: Prio Switching, the following backup function is provided:
DISABLED - no CB backup is provided CB1 -> CB2 - CB1 is considered as the primary switch. If the feedback is not deactivated within preset
period after Trp 1, the output Trp 2 is issued immediately to trip CB2 as backup. Bak Trp 1 is issued at the same time.
CB1 <- CB2 - CB2 is considered as the primary switch. If the feedback is not deactivated within preset
period after Trp 2, the output Trp 1 is issued immediately to trip CB2 as backup. Bak Trp 2 is issued at the same time.
CB1 <-> CB2 - both CBs provide a backup switching for each other. If the CB1 feedback doesn't
deactivate in preset period, CB2 is tripped, if the CB2 feedback doesn't come in preset period, CB1 is tripped.

TRIP and Fault Reset description

TRIP

TRIP may be considered as event or status of the unit:
TRIP event:
Starts in the moment of terminating the count-down of any protective function with delay, or in the moment of activation of any immediate protective function.
As a result of the trip event, are e.g. the following consequences:
o Immediate deactivation of outputs !Comm Trp o LED TRIP goes to red o History record is created
TRIP status:
Starts at the moment of TRIP event
During this status, the !Comm Trp output keeps in the fault position
During this status, it is not possible to perform Fault reset
TRIP status is active until a successful Fault reset. This may not be done before all measured and
evaluated values are within preset limits.
If during the TRIP status, caused by some value, another value overreached its limits for TRIP evaluation, this second overreach is not considered as TRIP. It does not cause a second TRIP event. However, as a consequence of this, the TRIP duration may be prolonged until the moment when both (all) values are within limits.

Fault reset

Fault reset is an event, caused by either of the following reasons:
Fault reset
Input input F.R. Button is activated
Automatic fault reset is performed according to the setting of General: Auto FR setpoint.
By activation or deactivation of binary input Block 1 or Block 2.
The abovementioned reasons are a trigger to provide Fault reset, however, it is successfully done only in case that the TRIP status is activated and all evaluated values have returned back into limits. If the TRIP status is not activated, or it is activated, but any of the values is still out of limits, Fault reset is not done and any of the mentioned triggers is forgotten. I.e., the unit may not be „provisionally“ fault­reset. By a successful Fault reset, the TRIP status is terminated.
button is pressed

Shared peripheries

The function is compatible with IG/IS-NT controllers. CAN2 interconnection between the gen-set controllers and InteliPro is necessary to allow this feature. Use the LiteEdit configuration window to configure the appropriate binary and analog values to be transmitted from InteliPro via the CAN2
communication. In the Configuration window, click the
button. The following window opens:

Page 24
Using the "Module address" selection box to adjust the address of the shared peripheries module and avoid collision with other module already present on CAN2 bus. Click on the appropriate Binary output or Analog output in the list to set-up the value to be transmitted via CAN2 bus to the gen-set controllers. The transmitted values are received by the IG/IS-NT controllers connected via the CAN2 bus. See more about configuring shared peripheries (Shared and Internal virtual I/O periphery and PLC) in IGS-NT-Application guide. The shared binary and analog outputs can be used for communicating out the binary statuses of CBs, trips of the particular protective functions or transmitting the value of mains import in kW, kVAr or kVA and further processing e.g. for the gen-set control or visualization of the site.

InteliPro is a modular electronic protective relay, providing complete list of protective functions. Each of the functions works as an autonomous protective stage, with its independent activation, setting of the limits and assigning of the Trp 1 and/or Trp 2 output and Block 1 and/or Block 2 input. Besides that, each activated protective function activates the Comm Trp output as described above. These settings are done in the setpoints menu, using the appropriate group of setpoints, assigned to its function. E.g. setting of overcurrent limits, trip outputs and blocking inputs is done in the setpoint group I>.
Activation/deactivation of a protective function:
In order to activate or deactivate a protective function, it is possible to use 2 means:
- In the setpoint group General, find the appropriate name of the function (e.g. Overcurr Prot for
overcurrent protection stage) with the possible setting: ALLWAYS / PARALLEL / DISABLED. To deactivate the complete protective stage in general, set this setpoint to DISABLED. To activate the protective stage in general, set the setpoint either to PARALLEL to activate this protective in case of both CB1 and CB2 are closed, or to ALWAYS to activate the function permanently regardless of the circuit breakers status.
- In order to e.g. activate only one adjustable pickup used within a multiple-stages protective
function, set this pickup limit to zero. E.g. InteliPro allows setting 2 stages of overvoltage protection. To use only V> and block the V>> stage, set the pickup limit V>> to 0V. In general, setting of any pickup limit of any protective function blocks this protection stage.
- To operatively enable or disable a protective stage during regular operation of the unit, assign
the Block 1 and Block 2 inputs to the appropriate protective function. By activation and deactivation of those inputs, enable or disable the appropriate protective stage. Enabling of a
protection stage is delayed by ProtActiv del after deactivation of the blocking input.
- It is possible, that in your unit, some optional protective functions are not activated. In such
case, the function is permanently blocked and even the setpoints related to it are not visible. In case that this protection is requested, please consult your sales representative regarding the options unlocking.
How to set-up trip outputs
To assign the appropriate trip outputs, which are operated by a particular protective stage, find the setpoint group, which contains the setting of this protective stage. E.g. for overcurrent, go to the setpoint group I>. In the setpoint group find the setpoint xxx Trp BO, where "xxx" is the abbreviation of the protective stage. It is possible to use the following setting:
- None: neither Trp 1 nor Trp 2 is activated in case of this protective stage trip. In such case,
only the Comm Trp output contains information about trip by this protection stage.
- Trp 1: binary output Trp 1 is activated in case of this protection stage trip.
- Trp 2: binary output Trp 2 is activated in case of this protection stage trip.
- Trp 1+2: both binary output Trp 1 and Trp 2 are activated in case of this protection stage trip.
- In all cases, the Comm Trp output contains information about trip from all activated protection
stages.
How to set-up blocking inputs
To assign the appropriate Block inputs to enable or disable the particular protective stage, find the setpoint group, which contains the setting of this protective stage. E.g. for overcurrent, go to the setpoint group I>. In the setpoint group find the setpoint xxx Block BI, where "xxx" is the abbreviation of the protective stage. It is possible to use the following setting:
- None: neither Block 1 nor Block 2 is used to enable or disable the protective stage.
- Block 1: binary input Block 1 is used to enable or disable the protective stage.
- Block 2: binary input Block 2 is used to enable or disable the protective stage.
- Block 1+2: both binary inputs Block 1 and Block 2 are used to enable/disable the protective
stage. The input signals are connected by logical OR function.

Protective functions in detail

Overvoltage, Undervoltage (ANSI 59, 27)

The RMS value of measured voltage is compared with the preset limit of overvoltage or undervoltage. When any of the preset limits is over/underreached, the output U Sig moves to fault-indicating position immediately. If the voltage of the given phase keeps out of limits for the delay of the appropriate stage, TRIP is issued. As the voltage returns back within limits in all measured phases, the U Sig output stop to signal the fault state immediately, regardless of whether TRIP was issued or not or Fault reset was performed or not. Both overvoltage and undervoltage protective stages provide possibility of setting 2 levels with independent delay assigned to each level.

Overfrequency, Underfrequency (ANSI 81 H, L)

The frequency value measured on phase L1 is compared with the preset limit of overfrequency or underfrequency. When any of the preset limits is over/underreached, the output f Sig moves to fault­indicating position immediately. If the frequency keeps out of limits for the delay of the appropriate stage, TRIP is issued. As the frequency returns back within limits, the f Sig output stops to signal the fault state immediately, regardless of whether TRIP was issued or not or Fault reset was performed or not. Both overfrequency and underfrequency protective stages provide possibility of setting 2 levels with independent delay assigned to each level.

Voltage unbalance (ANSI 47)

The voltage unballance is evaluated in case that amplitude difference between any 2 phases overreaches the preset limit V Unb: V Unb. It refers to the amplitude unbalance of the measured voltage.

"Loss of mains" protections

InteliPro provides two different methods for fast evaluation of loss of mains (LOM), into which the generator operates:
- Vector shift
- Rate Of Change Of Frequency
The loss-of-mains protections setting is done using the setpoints in the group LOM.

Vector shift (ANSI 78)

Vector shift is one of the LOM protections. It provides very fast detection of mains failure (in units or tens of ms), based on the principle of shift of the synchronous generator displacement angle. The displacement angle is an angle between magnetic field of a rotor and the rotating magnetic field of the stator winding and relates strongly to the load of the generator. In case that this load changes, the displacement angle immediately changes by a "jump". Compared to the frequency decrease, which probably also occurs, this jump is an immediate phenomena and is detected as a shift of the measured voltage sine curve - Vector shift or Vector jump. Depending on the preset limit in degrees [°], it allows immediate disconnection of very fast failures and thus prevention of severe damages which could not be prevented within the delay of frequency or voltage protections.

Page 27
Vector shift reaction times are usually requested up to 30ms. Typical setting is shown e.g. in G59/2 standard (see below).

Rate Of Change Of Frequency (df/dt, ROCOF, ANSI 81R)

ROCOF is second most frequently requested method of LOM detection. In principle, the method uses similar evaluation method like Vector shift, but the physical phenomena detected is different. It calculates the change of speed of the generator, caused by sudden change in its load, together with unintentional islanding situation (loss of mains), which is normally capable of keeping the frequency on a stable level. The frequency change is expressed as tangent in time [Hz/s]:

2-9
Page 28
It is a fast protection, similar to Vector shift, however, unlike Vector shift, which detects immediate phenomena, the tangent calculation requires a certain time for evaluation. In ComAp protection relays, the evaluation time for ROCOF protection can be adjusted in number of sine curve cycles being taken into evaluation from 1 to tens of cycles (each having 20ms). This allows to set up the ratio between the evaluation speed and sensitivity to nuisance trips.

Overcurrent: definite-time, IDMT and with voltage control

InteliPro provides three types of mains-overcurrent with different setting of the protection delay:
Definite time overcurrent (ANSI 50):
The trip is issued in a given delay after the current exceeds preset limit. The setting is done using the setpoints
IDMT overcurrent (ANSI 51)
The IDMT (inverse definite minimum time) overcurrent provides delayed overcurrent trip, based on calculation of the trip delay according to the trip curve:
in the group I>.
I> Del
The delay, i.e. the IDMT curve shape is prescribed by the DNO, based on the calculations of short­circuit conditions in the point of the generator connection. The grid protections are coordinated and allow for isolating the faults by the protections which are located closer to the short-circuit area. This way, the discrimination of the breakdown point is done by the short-circuit current magnitude allowing the generator to ride-through a distant faults and contribute to recover the mains voltage after the fault is disconnected. The setting is done using the setpoints
The shape of IDMT curve can be selected using the parameter I> T: I> T Curve. If the option IDMT is
selected, the shape is given by the following formula:
in the group I> T.
I> Del *
The parameter I> T: I> T Curve allows also to set other switching curves according to the IEC
standards.

Page 29
Time overcurrent with voltage control and restraint (ANSI 51V)
The voltage control of time overcurrent assures that the protection is blocked in case that the measured voltage is above the level set by the setpoint I> V: I> V Control. The voltage restraint function is a modification of the IDMT overcurrent protection. It uses the same mechanism of the delay calculation according to the IDMT trip curve, but the delay is further adjusted according to the measured voltage:
This protection functionality uses the fact that voltage in the point of short-circuit drops to zero or very low values and with growing distance from the fault, it increases up to the mains nominal voltage value. Thus, increased sensitivity to the short-circuits localization and protection coordination is provided. The setting is done using the setpoints
in the group I> V.

Neutral overcurrent (ANSI 50N, ANSI 51N)

To allow measurement of the neutral overcurrent, the plug-in module Relay Card CT2-REL2 is necessary. The protection stage allows to set up instantaneous neutral overcurrent or IDMT overcurrent, similar to the mains overcurrent protective functions. The setting is done using the setpoints group EFC.

Current unbalance (ANSI 46)

The current unbalance protection is used to avoid unballanced load in the point of mains connection. The setting is done using the setpoints in the setpoint group I Unb.

Directional overcurrent (DOC, ANSI 67)

DOC is sensitive for location of the fault with relation to the measurement point. This way, directional protection is capable to detect whether the fault happened "in front of it" or "behind". Directional overcurrent protection, applied in the point of generator connection to mains, is considered a loss of mains protection, however it does not substitute the traditional loss of mains protections like Vector shift or ROCOF. The typical application is a generator running in parallel to mains with its own load consumption (e.g. peak shaving, soft transfer stand-by, or other applications). The generator is usually used to support the local consumption with no export to the mains. In case of mains transition into an island mode, the generators, running in parallel with the islanded area, would start to supply its complete consumption, generating current in opposite direction. DOC protection is used to avoid this situation, and trip the generator from the islanded mains, combining the overcurrent protection together with its directional character. Compared to the "reverse power protection", DOC protection detects also reactive currents from the given angle zone, what allows better sensitivity for tripping.

Neutral Voltage Displacement (NVD, ANSI 59N)

NVD protective function is used in medium or high voltage systems with isolated or indirectly grounded zero-point. Under healthy conditions of the system, the sum of the three phase-to-earth voltages should balance to zero. When an earth-fault occurs, it does not cause a short-circuit, because of the isolation of the system in the zero point. However, the fault provides connection of one phase with earth what represents hazard for the system safety (ground-fault in any other phase would then mean a phase-to phase short-circuit, phase-to-ground voltage of the other phases may fluctuate to multiples of its nominal, providing increased stress to the isolation system, etc). One of the effects of the fault is a rise in the neutral voltage, so called neutral voltage displacement. This neutral voltage displacement is measured in a specific "open-delta" connection of voltage transformers, shown in the chapter Voltage and current inputs. In some cases, it is required to clear the fault by tripping the appropriate circuit breaker. However, the NVD protection itself does not allow detecting the location of a fault and for this reason it is sometimes used only for providing an earth-fault alarm. It is possible to set whether the NVD contributes to the common trip of the relay or uses its own separate output for signalization of the NVD alarm. The setting is done using the setpoints in the group NVD.

Directional power (ANSI 32)

InteliPro provides two stages of power protections, both of them allowing setting of either overreaching the preset limit or underreaching it. This way, all of the following protections are realized:
- Mains reverse power (protection of unintentional export)
- Generator reverse power (protection of motoric operation)
- Minimum import underreaching (timely trip in case of unintentional export approaching)

2-12
Page 31
The setting is done using the setpoints in the group P<>.

Synchro check (ANSI 25)

This function checks state of synchronism at both sides of the circuit breaker. It is used as a supplementary function to automatic reconnecting of the other functions to assure that the synchronous conditions are met before the circuit breaker closes back by the protection relay, or is unblocked to be closed by some other device. In InteliPro, either L1-L2 phase-to-phase voltage or L1­N phase-to-neutral voltage is measured on the generator side of the circuit breaker and compared with the corresponding measured mains voltage. Whether phase-to-phase or phase-to-neutral voltage is used is decided by the setpoint Basic Settings: Voltage Setup. Synchronous conditions are evaluated based on the preset window of voltage, frequency and angle match as set in the setpoint group Sync Check.

AC reclosing (ANSI 79)

The automatic reclosing mechanism is generally used in situation, where temporary nature of the failure is expected. The protection relay trips the breaker according to the standard protection settings. As soon as the trip conditions disappear, i.e. the protection senses fault-free situation, the tripping output deactivates and after a reclosing delay, the reclosing output issues a signal to automatically reclose the breaker. There may be several reclosure attempts done in case of unsuccessful reclosure cycle. The setting is done using the setpoints in the group AC Reclosing.

CAN bus and RS485

For wiring of CAN bus communication, the following rules are to be maintained:
Maximal length of the CAN bus depends on the communication speed. For the speed of
250kbps, which is used on the CAN1 bus (extension modules) and CAN2 bus if it is switched to 32C mode the maximal length is 200m. If the CAN2 bus is switched to 8C mode by the setpoint Comms settings: CAN Bus Mode, the speed is 50kbps and the maximal length is 800m.
The bus must be wired in linear form with termination resistors at both ends. No nodes except
on the controller terminals are allowed. Use cable with following parameters:
Cable type Shielded twisted pair
Impedance 120
Propagation velocity >= 75% (delay <= 4.4 ns/m)
Wire crosscut >= 0.25mm2
Attenuation (@1MHz) <= 2dB/100m

Setting Explanation
Trp 1+2 Both Trp 1 and Trp 2 outputs are activated in case of binary alarm

CB1 Feedback

This input indicates, whether the circuit breaker CB1 is open or closed. It is expected that this breaker opens in case of CommTrp and Trp 1 activation. If it is configured in the unit and it does not open, CB1 fail is indicated.
In general, this breaker corresponds to the "Mains Circuit Breaker" = MCB in the ComAp controllers applications. Together with CB2 it indicates, whether the installation is in "parallel to mains" state (both CB1 Feedback and CB2 Feedback are closed) or in island mode (one or both of CB1 Feedback or CB2 Feedback are open).

CB2 Feedback

This input indicates, whether the circuit breaker CB2 is open or closed. It is expected that this breaker opens in case of Trp 2 activation. If it is configured in the unit and it does not open, CB2 fail is indicated.
This breaker can, but does not necessarily have to correspond to the "Generator Circuit breaker" = GCB as used in the ComAp controllers applications. In such case, together with CB1 it indicates, whether the installation is in "parallel to mains" state (both CB1 Feedback and CB2 Feedback are closed) or in island mode (one or both of CB1 Feedback or CB2 Feedback are open).

F.R. Button

Activation of this binary input causes fault reset. The input has the same effect as pushing the Fault
Reset button internally.
. If permanently activated, every 100ms an impulse to fault reset the unit is done

DC TripCircuit

Evaluation of DC trip circuit state. When the input closes, history record is made and a message "Wrn DCTripCirc" appears in Alarmlist.

Access Lock

If the input is closed, no setpoints can be adjusted from controller front panel.
Hint:
Access lock does not protect setpoints from LiteEdit. To avoid unqualified changes the selected setpoints can be password protected.

External Trip

The input serves for reading the state of external mains failure relay for the purpose of controlling the NVD protection stage. Its activation means that the external relay has detected a mains failure. If the input is active, NVD trip outputs are blocked. To unblock the NVD protection, it is necessary not only to deactivate the External Trip input, but also deactivation of the feedback of the circuit breaker, which is operated by the NVD protection stage. If the input changes its state, history record is made. There is no Alarmlist record or trip protection connected with this input. See description of this lockout in ANSI59N - NVD function description.

Block 1, Block 2

These inputs are used to disable a certain protection stage. To allow disabling/enabling the protection stage by these inputs, assign them to this protection stage by setpoint Block BI. Enabling the
connected protection is delayed by time given by setpoint ProtActiv del. Please note that the Block inputs trigger immediate fault reset in the moment of thier activation and deactivation.

Library of binary output functions

Some binary output signals are provided in both positive and negative logic in order to follow the requirements of the application:
Due to increased safety requirements, some protective relays require that negative logic is used, assuring that loss off power supply always causes the relay to trip. I.e. the relay contacts are used, with fault-free position maintained in energized state. In case of power supply fail, the unit goes to “fault” indication position. The outputs using negative logic are marked with exclamation mark "!" as the first character of their name.
In some applications, the negative logic is not a required functionality. The function of opening the circuit breaker in case of loss of power supply is not accepted as a safety point and the safety is assured by different means e.g. in the superior system or within the protection relays intertripping scheme. In such case, the outputs with positive logic (without the exclamation mark) can be used to signal the detected failure state.

Common Alarm

The output closes in case any alarm comes up. The output opens if Fault Reset button is pressed.
