2 System overview
2.1 General description
InteliCompactNT (also IC-NT) Family controllers are comprehensive gen-set controllers for single and
multiple generating sets operating in stand-by or parallel modes. A modular construction allows
upgrades to different levels of complexity in order to provide the best solution for various customer
applications. The controllers are equipped with a powerful graphic display showing icons, symbols and
bar graphs for intuitive operation, which, together with its high level of functionality, sets new
standards in Gen-set controls.
The key features are:
Easy-to-use operation and installation. The factory default configuration covers most
applications
Various customizations are possible thanks to its configurability
Excellent remote communication capabilities
High level of support for EFI engines (most world producers)
High reliability
2.2 Configurability and monitoring
One of the key features of the controller is the system’s high level of adaptability to the needs of each
individual application and wide possibilities for monitoring. This can be achieved by configuring and
using the powerful ComAp PC/mobile tools.
Supported configuration and monitoring tools:
- LiteEdit –complete configuration and single gen-set monitoring
- InteliMonitor –multiple site monitoring and setpoint setting
- WinScope –special graphical monitoring software
- WebSupervisor –web-based system for monitoring and controlling
oWebSupervisor mobile –supporting application for smartphones
NOTE:
Use the LiteEdit PC software to read, view and modify configuration from the controller or disk and
write the new configuration to the controller or disk.
The firmware of InteliCompactNT contains a large number of binary inputs and outputs needed for all
necessary functions available. However, not all functions are required at the same time on the same
gen-set and also the controller hardware does not have so many input and output terminals. One of
the main tasks of the configuration is mapping of “logical” firmware inputs and outputs 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. Selection of peripheral modules which are connected to the controller and doing the same as
the above for them
6. Selection of ECU type if an ECU is connected
7. Changing the language of the controller interface

PRINCIPLE OF BINARY INPUTS AND OUTPUTS CONFIGURATION
The controller is shipped with a default configuration, which should be suitable for most standard
applications. This default configuration can be changed only by using a PC with the 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 when no communication module is permanently
attached.
Once the configuration is modified, it can be saved to a file for later usage with another controller or for
backup purposes. The file is called archive and has the file extension .aic. An archive contains a full
image of the controller at the time of saving (if the controller is online for the PC) except the firmware.
Besides configuration it also contains current adjustment of all setpoints, all measured values, a copy
of the history log and a copy of the alarm list.
The archive can be simply used for cloning controllers, i.e. preparing controllers with identical
configuration and settings.

ISLAND-PARALLEL OPERATION WITH AMF AND WITHOUT PARALLELING
2.4 True RMS measurement
This controller measures AC values based on the True RMS principle. This principle corresponds
exactly to the physical definition of alternating voltage and current effective values. Under normal
circumstances the mains voltage and current should have a pure sinusoidal waveform. However,
some nonlinear elements connected to the mains produce harmonic waveforms with frequencies of
multiples of the basic mains frequency and this may result in deformation of the voltage and/or current
waveforms. The True RMS measurement gives accurate readings of effective values not only for
pure sinusoidal waveforms, but also for deformed waveforms.
NOTE:
The harmonic deformation causes that the Power Factor of a generator working parallel with the
mains cannot reach values in a certain range around the PF 1.00. The higher the deformation, the
wider the power factor dead range. If the requested power factor is adjusted inside the dead range,
the controller cannot reach the requested value because of this fact.

3.6 Wiring
Tightening torque, allowed wire size and type, for the Field-Wiring Terminals:
Based on terminal type:
1. PA256:
SPECIFIED TIGHTENING TORQUE 0.5 NM (4.4 IN-LB)
2. 2EDGK:
SPECIFIED TIGHTENING TORQUE 0.4 NM (3.5 IN-LB)
For field type terminals:
Use only diameter 2.0–0.5 mm (12–26 AWG) conductor, rated for 75 °C minimum.
For Mains (Bus) Voltage and Generator Voltage terminals
Use only diameter 2.0-0.5 mm (12–26 AWG) conductor, rated for 90 °C minimum.
Use copper conductors only.
3.7 Grounding
The shortest possible piece of wire should be used for controller grounding. Use cable min. 2.5 mm2.
A brass M4x10 screw with star washer securing ring type grounding terminal shall be used.
The negative “-” battery terminal must be properly grounded.
Switchboard and engine must be grounded at a common point. Use as short a cable as
possible to the grounding point.
3.8 Power supply
To ensure proper function:
Use min. power supply cable of 1.5 mm2
The maximum continuous DC power supply voltage is 36 V DC. The maximum allowable power
supply voltage is 39 V DC. The InteliCompact’s power supply terminals are protected against large
pulse power disturbances. When there is a potential risk of the controller being subjected to
conditions outside its capabilities, an outside protection device should be used.
It is necessary to ensure that potential difference between the generator current COM terminal
and the battery “-” terminal is maximum ±2 V. Therefore, it is strongly recommended to
interconnect these two terminals together.
HINT:
The InteliCompactNT controller should be grounded properly in order to protect against lighting strikes!!
The maximum allowable current through the controller’s negative terminal is 4A (this is dependent on
binary output load).

For connection with a 12 V DC power supply, the InteliCompactNT includes internal capacitors that
allow the controller to continue operation during cranking if the battery voltage dip occurs. If the battery
voltage is 10 V before the dip and it recovers to 7 V within 100 ms the controller continues operating.
During this voltage dip, the controller screen backlight may turn on and off but the controller keeps
operating.
It is possible to further support the controller by connecting the external capacitor and separating
diode or I-LBA module:

The capacitor size depends on the required time. It shall be approximately in the thousands of
microfarads.
The capacitor size should be 5000 microfarad to withstand a 150 ms voltage dip under the following
conditions:
Voltage before dip is 12 V, after 150 ms the voltage recovers to the min. allowed voltage, i.e. 8 V.
HINT:
Before the battery is discharged the message "Low BackupBatt" appears.
Or by connecting a special I-LBA Low Battery Adaptor module:

--
The I-LBA module ensures a min. 350 ms voltage dip under following conditions:
Communication and extension plug-in modules are connected.
Voltage before dip is 12 V and after 350 ms the voltage recovers to the min. allowed voltage
5 V.
The I-LBA enables controller operation from 5 V DC (for 10 to 30 seconds).
The wiring resistance from the battery should be up to 0.1 Ωfor proper function of the I-LBA.
HINT:
I-LBA may not eliminate voltage drop when used with the low temperature (-40 °C) version of the
controller and the display heating element is on (below 5 °C). The current drain of the heating element
exhausts LBA capacitors very fast.

3.8.1 Power supply fusing
A one-amp fuse should be connected in line with the battery positive terminal to the controller and
modules. These items should never be connected directly to the starting battery.
Fuse value and type depends on the number of connected devices and wire length.
The recommended fuse type (not fast) is T1A due to internal capacitors charging during
power up.
