Engine Control
Description
The M2000 Engine Control controls start and stop of the
engine, monitors and protects the engine during start and
operation, and simultaneously indicates the engine and alarm
status on the front of the unit. It has 9 shutdown/alarm inputs.
It is controlling the cranking, fuel valve and stop solenoid of
the engine. It is possible to configure the unit to perform up
to 6 start attempts, with user configurable crank and rest
periods. When the engine fires, cranking will be disconnected
by activating the crank disconnect input from a tacho relay or
from a direct measurement from a magnetic pick up. When
stopping the engine, a generator circuit breaker trip is available
for genset applications. A stop delay can be configured for
cooling down the engine before stop. M2000 includes cable
check of all sensor inputs. Basic configuration can be set by
dip-switches on the rear of the unit.
Extended configuration is possible using a PC. Easy installation
is ensured by means of clamping fittings, and plug-in
connection terminals. The M2000 includes an RS485 interface
enabling MODBUS RTU communication. The M2000 has been
designed and tested for use in harsh environments.
