General description

Description of the controller system (with all options)

NT Family controllers are comprehensive AMF-controllers for single and multiple generating sets operating
in stand-by or parallel modes.
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.
The controller automatically starts the gen-set, closes the Gen-set C.B. when all conditions are met, then
stops the engine on external signal or by pressing push buttons.
Parallel to the Mains operation is a standard feature. Isolated parallel and Power Management System
support are optional. Forward and reverse synchronizing, Generator protections, Mains protection including
vector shift, load and power factor control are the major functions provided. Interfacing to foreign
synchronizers and load sharers is supported. Regarding the measurement inputs, the controller provides
True RMS method for voltage, current and power measurement.
The key feature of the controller is its easy-to-use operation and installation. Predefined configurations for
typical applications are available as well as user-defined configurations for special applications.

SPTM

This manual describes "SPtM" application type, which is designed to control a single-operating genset in
long-term parallel mode as well as in emergency mode. The application provides following main
features:
•
automatic start and stop sequences
•
engine and generator protections
•
two breakers control (MCB, GCB), both synchronized
•
mains protections including vectorshift
•
AMF function (autostart due to mais failure)
•
parallel to mains operation, various load control modes (constant, import/export..)
•
island operation
•
no-break transfers from island to parallel and vice versa
