Product Description:

AFTER SALES SERVICE
Like all CRE Technology products, the
unit also benefits from our technical
support. All CRE products are delivered
with one year warranty.
INPUTS
DC SUPPLY: 12 or 24 volts DC, (+) and
(-) terminals.
R-S-T: mains phase voltages.
MN: mains neutral terminal.
G: Generator phase voltage.
GN: Generator neutral terminal.
OUTPUTS
MAINS CONTACTOR:
Normally closed relay output connecting
the phase-R voltage to the terminal.
(10amps@250V-AC)
GENERATOR CONTACTOR:
Normally open relay output connecting
the phase-G voltage to the terminal.
(10amps@250VAC)
REMOTE START:
Normally open engine start request relay
output. Connects the battery positive
to the terminal.
(10amps@28V-DC
The MNS is a basic, microprocessor controlled unit designed to monitor 3-phase mains voltages, send remote start commands to the generating set, and manage changeover of both the generator and the mains contactors.The genset should be controlled by a Remote Start control unit.

A SIMPLE PRODUCT FOR BASIC APPLICATIONS
The functions have been reduced to the minimum. The front panel mimic diagram
provides information about the mains and generator power availability
as well as contactor positions.
The MNS continuously monitors the AC mains phase voltages. If at least one of
the phase voltages goes outside set limits, it triggers a transfer cycle.
SPECIAL TEST MODE FUNCTION
The MNS provides a TEST mode pushbutton allowing the genset to be tested
without a mains failure. The Test mode is also called the Emergency Backup
mode which keeps the genset running and makes a quick transfer in the event
of a mains failure.
HIGH COMPATIBILITY AND FLEXIBILITY
Because of the simplicity of its connections, the MNS may be used with most
commercially available or custom built engine control systems.
The lower limit of the mains and genset voltages may be manually adjusted via
the potentiometer found on the left hand side of the unit. The upper voltage
limit is factory set.
The unit uses two part connectors for easy replacement
RELIABLE AND EASY TO USE
The MNS is dedicated to basic applications which require no extra costs or
expensive hardware.
All CRE Technology products aim to provide the same satisfaction levels. The
MNS has passed EMC and low voltage tests, and each unit is 100% tested before
delivery.
