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 bar-
graphs 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
