Auxc2000 Motorized Change Over switch connection& parameterization

The AuXC-2000 control unit has been designed to offer stateof-
the-art functions for automatic transfer switching applications between
two three-phase sources, both utilities or generators. Built with dedicated
components and extremely compact, the AuXC-2000 combine the
modern design of the front panel with practical installation and LCD screen
that provides a clear and intuitive user interface.
Auxiliary supply : 100-240 VAC 50/60 Hz.
128x80 pixel, backlit LCD screen with 4 grey levels.
5 keys for functions and setting.
4 LEDs for plant synoptic (source line and breakers status).
2 LEDs for alarm presence and AUTO mode active.
5-language text for measurements, settings and messages.
Advanced programmable I/O functions.
High accuracy TRMS measurement.
Line 1: 3-phase + neutral voltage reading input.
Line 2: 3-phase + neutral voltage reading input.
Switching between line-to-line, line-generator or generator-generator.
Control of motorized circuit breakers, motorized changeover switches,
or contactors.
Management of automatic test for generators with emergency and
rotation.
Control of voltage source for three-phase, two-phase or single phase
systems.
Control of phase-phase and / or phase-neutral voltages.
Controls of undervoltage, overvoltage, phase loss, asymmetry,
minimum frequency, maximum frequency, with independent enabling
and time delay.
