2 System overview

2.1 General description

InteliMains-NT controller is comprehensive mains supervision controller for multiple generating sets
operating in parallel to the Mains. A modular construction allows upgrades to different levels of
complexity in order to provide the best solution for various customer applications.

NT Family controllers are equipped with a powerful graphic display showing icons, symbols and bar­graphs for intuitive operation, which sets, together with high functionality, new standards in Gen-set
controls.

BaseBox versions of InteliMains controllers are now available. This version features controller without
built-in monochromatic display and can be combined with new and powerful display units InteliVision-8
and InteliVision-5. For more information on these products, please go to comap.cz web pages.

The controller automatically connects the group of gen-sets to the Mains. It features mains failure
detection using integrated Mains protections, MCB and MGCB synchronization, configuration level
switches based on Mains import or object consumption.

The controller provides easy-to-use operation and installation. Predefined configurations for typical
applications are available as well as user-defined configurations for special applications.

NOTE:

In versions below 2.6 the IM-NT controller does not accept an external bus supply (bus supply which
is not controlled by a ComAp controller).

Gensets have to be in AUT mode to ensure proper MGCB function.
The key features are:

 Automatic gen-set start when the mains fails (BI SYS START/STOP is closed)
 MCB controlled by InteliMains-NT
 Break transfer on mains failure
 MCB synchronizing after mains return
 Power management (load dependent start and stop)
 Gen-set priority can be defined manually or automatically based on running hours equalization

or load demand (most efficient combination)

 Load sharing and VAR sharing
 Gen-sets soft loading and unloading
 Voltage matching
 Reverse power protection
 Full PLC logic included
 Support of redundancy controller
 MGCB support
 Group Link function
 Active calls and SMS

Use min. 1 mm2 cables for wiring of binary inputs.
NOTE:

The name and function or alarm type for each binary input have to
be assigned during the configuration. Binary inputs may be used in
built-in PLC as well. Please refer to the manual of GenConfig for
more information.

It is recommended to use separation diodes when multiple binary
input terminals are connected together to prevent unwanted
activation of binary input when one of the controllers is switched off.

3.9 Binary Output wiring

3.9.1 IM-NT

Correct wiring for Binary output is shown in the diagram below. On the left +PWR BOUT is not used,
on the right +PWR BOUT is used. If Binary outputs are connected directly to the power source,
additional fuse should be used.

NOTE:

If +PWR BOUT is used, it increases power consumption of the controller.

The wiring of the CAN bus communication should be provided in such a way that the following rules
are observed:

 The maximum length of the CAN bus depends on the communication speed. For a speed of

250 kbps, which is used on the CAN1 bus (extension modules, ECU) and CAN2 bus if it is
switched to 32C mode, the maximum length is 200 m. If the CAN2 bus is switched to 8C mode
the speed is 50 kbps and the maximum length is 800 m.

 The maximum length of the RS485 bus is 1000 m
 The bus (CAN and RS485) must be wired in linear form with termination resistors at both

ends. No nodes are allowed except on the controller terminals.

NOTE:

A termination resistors at the CAN and RS485 are already implemented on the PCB. For
connecting, close the jumper near the appropriate CAN or RS485 terminal. For more
information on jumper settings please refer to the section 3.1.4 Jumper setting.

 Use a cable with following parameters:

CAN AND RS485 BUS TOPOLOGY

NOTE:

See the website www.can-cia.org for information about the CAN bus, specifications, etc.
