Introduction
Congratulations to your purchase of ComAp InteliPro protection relay unit! InteliPro is a
microprocessor-based door-mounted protective device, providing a comprehensive set of protective
and supplementary functionalities. ComAp unique modular concept of HW extension modules, SW
options and full configurability allow perfect solution for most of the generator-to-mains parallel
applications.
For the complete list of protective functions please refer to the chapter Protective functions in detail in
the Application guide. The full configurability feature allows to cover advanced requirements for mains-
decoupling (inter-tie,„G59/3“),aswellasother advanced protection applications.
Conformity declaration
Following described machine complies with the appropriate basic safety and health
requirement of the EC Low Voltage Directive No: 73/23 / EEC and EC
Electromagnetic Compatibility Directive 89/336 / EEC based on its design and type,
as brought into circulation by us.
VDE O126-1-
1
The unit is certified to comply to the appropriate requirements of the
standard DIN V VDE V 0126-1-1 (certificate ref. 44 207 11 398020,
available upon request), with the following conditions:
The conformity with the Standard DIN V VDE V 0126-1-1,
chapter 4.1/ 6.1, which is declared in the certificate 44 207 11
398020, requires the tolerance against one fault. In order to fulfil
this functional safety requirement, a redundant architecture has
to be built by the usage of two certified units.
It has to be ensured that each of both units is connected to an
output (relay) which is capable to induce opening of the
operated contactor.
Warnings
Be aware that the relay outputs can change state during and after the unit
setting (before the unit is used again ensure that the proper setting is done)!!!
Be aware that the devices connected to binary outputs of the unit may operate
upon disconnection of power supply, measurement inputs and/or binary
inputs!!!
!!! CAUTION !!!
Dangerous voltage

Binary inputs
The binary inputs of the unit are used to receive basic information about the installation site, its
operational state and conditions. They can be also used for control of the unit operation, i.e. blocking
of protective functions, induce tripping by binary signals or providing remote fault reset signal.
To wire the binary inputs correctly, please use the following picture. The black line is to be wired to the
unit, the blue line indicates internal arrangement of the unit. Use min. 1 mm2cables for wiring of binary
inputs.
NOTE:
The name and function or alarm type for each binary input have to be assigned during the
configuration.

1-12
Binary outputs
Use min. 1 mm2cables for wiring of binary outputs. Use external relays as indicated on the schematic
below for all outputs except those where low-current loads are connected (signalization etc..).
NOTE:
The function of each output has to be assigned during the configuration.
CAUTION!
Use suppression diodes on all relays and other inductive loads!
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 name, sensor characteristic and alarm types for each analog input have to be assigned during the
configuration.
Relay Card CT2-REL2 plug-in module
As a default, the unit is supplied with the plug-in module Relay Card CT2-REL2 plugged in the unit.
The module provides:
2 relay outputs allowing voltage-free output contacts
5 A current measurement input
50 mA current measurement input
It is possible to operate the unit also without the Relay Card CT2-REL2 if none of the above
mentioned functions is requested for the application. In that case, it can be removed and the plug-in
slot can be used for inserting another plug-in expansion module, e.g. IC-NT CT-BIO7 to expand the
configurability of binary inputs/outputs.
Relay outputs
The relays on the Relay Card CT2-REL2 module provide a set of 2 NO contacts with possibility of
configuration of any logical binary output. By default, the functions !Comm Trp and !Bak Comm Trp
are configured to those outputs. To change the configuration of the relay outputs function, use the
configuration tool in LiteEdit PC software.
Current inputs
The module Relay Card CT2-REL2 provides two current inputs for purpose of the Earth Fault Current
and Ground Surge Current evaluation. When wiring the current inputs, please make sure that the
wires are connected to the correct current measurement input to prevent damage of the 50 mA
input by excessive current!

InteliPro, SW version 1.4, ©ComAp –April 2014
InteliPro 1.4 Comprehensive Guide - rev. 1

Power supply
The unit is designed for 8 - 36 VDC (typically 24V or 12V battery, battery charger or inverter) power
supply. Use secured power supply voltage to assure operation of the InteliPro protection relay even
during power supply outages! In case that no suitable DC supply circuits are available on-site, we
recommend to use an appropriate inverter AC to 24 VDC. In case of need, ask ComAp technical
support at [e-mail] for recommendations.
Recommended wiring
In the diagram below, see the typical wiring of the InteliPro unit inputs and outputs. The wiring is to be
considered as an example for the default configuration and operation mode with 1 common trip output.
The relay contacts of Relay Card CT2-REL2 module can be reconfigured to Trip 1 and Trip 2 outputs
in case of operation with 2 trip outputs, as well as any inputs and outputs can be reconfigured to the
particular needs of the application.
An OFF coil of a circuit breaker is to be wired to terminals RE11 and RE14 or to terminals RE21 and
RE24 on extension module.

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 4.6.8 or higher is necessary. Visit
www.comap.cz for download or update of this PC application and its manuals.
The firmware contains large number of binary inputs and outputs for different functions. Those that are
required by operation of a particular application can be mapped to the physical terminals of the unit.
One of main tasks of the configuration is this mapping of "logical" firmware input and output signals to
the "physical" hardware inputs and outputs.
Configuration parts:
1. Mapping of logical binary inputs (functions) assigning alarms to physical binary input
terminals
2. Assigning the "normally closed" or "normally opened" functionality to the inputs
3. Mapping of logical binary outputs (functions) to physical binary output terminals
4. Assigning sensor characteristics and alarms to analog inputs
5. Assigning control values and output characteristics to analog outputs
6. Selecting of peripherial modules which are connected to the controller and doing the same as
above for them
7. Changing language of the unit texts
NOTE:
Some of the logical binary outputs provide also the reversed functionality. Those LBOs are marked
with exclamation mark "!" as the first character of their name.
See more in the Introduction or Library of binary output functions chapters.
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.

InteliPro, SW version 1.4, ©ComAp –April 2014
InteliPro 1.4 Comprehensive Guide - rev. 1
1-17
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.
CONFIGURATION WINDOW IN LITEEDIT
CAUTION!
The firmware of this version is compatible only with the archive version 1.4. It is not possible to use for
instance the archive version 1.3.
System of optional functions
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:
