WIRING OF BINARY OUTPUTS
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.
Analog inputs can be used also as binary or tristate, i.e. for contact sensors without or with circuit
check. The threshold level is 750Ω. In case of tristate, values lower than 10Ω and values over 2400Ω
are evaluated as sensor failure (short or open circuit).
WIRING OF ANALOG INPUTS - USED AS BINARY OR TRISTATE
NOTE:
The name, sensor characteristic and alarm types for each analog input have to be assigned during the
configuration.

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
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
The unit offers wide range of protective functionalities. To allow flexibility of the protective functions at
the particular application, some of the features are provided as SW options. These functions are
unlocked by a software dongle, delivered by ComAp or its approved distributors. The SW dongle is a
unique number generated according to the serial number of the unit and the selected protective
functions. The functions are referred by their ANSI numbers, according to the following table:
IPro-25 Synch Check
IPro-51V Time over current with voltage control
IPro-59N Neutral voltage displacement
IPro-67 Directional overcurrent
IPro-78 Vector shift
IPro-79 AC reclosing relay
IPro-81R Rate of change of frequency + rocof filter
The appropriate selection of InteliPro optional functions is to be marked on the rear side of the unit:
For unlocking the desired functions or changing those functions that are already unlocked, contact
your sales person for the appropriate SW dongle. The following information will be needed:
Entering the SW dongle:
once received the appropriate SW dongle relative to the unit serial number, go to the setpoint Basic

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.
•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 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.

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
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.
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.
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]:
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
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.
The following image shows the conditions of activation of Directional Overcurrent protection in
InteliPro – i.e. critical angles between voltage and current, given the voltage is placed at the 0°angle:

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)
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.
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:
See the web page www.can-cia.org for information about CAN bus, specifications etc.
Recommended CAN/RS485 connection
CAN bus connection
The bus has to be terminated by 120 Ohm resistors at both ends. External units can be connected on
the CAN bus line in any order, but keeping line arrangement (no tails, no star) is necessary. Standard
maximum bus length is 200m for 32C CAN BUS MODE and 900m for 8C CAN BUS MODE. Shielded
cable has to be used, shielding has to be connected to PE on one side (controller side).

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.
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.
