Electronic Engine Control
Genset controller 704 generator controller
The 704 is an Auto Mains Failure ControlModule that offers an excellent range of engine monitoring and protection features. The module has been designed to monitor engine temperature, low oil pressure, fail to start, charge failure, over speed and under speed.
When the module detects a fault condition it automatically shuts down the engine. The module also
includes two user configurable auxiliary inputs

Specification
SUPPLY
CONTINUOUS VOLTAGE RATING
8V to 35V continuous
CRANKING DROPOUTS
Able to survive 0V for 50mS, providing supply was at least 10V before dropout and supply recovers to 5V. This is achieved without the
need for internal batteries.
MAXIMUM OPERATING CURRENT
50mA
TYPICAL CURRENT
12mA
CHARGE FAIL
8 Volt Charge Fail at 12 Volts
16 Volt Charge Fail at 24 Volts
INPUTS
ALTERNATOR INPUT RANGE
75V(L-N) to 333V AC (L-N) absolute maximum
ALTERNATOR INPUT FREQUENCY
50Hz 60Hz at rated engine speed
(minimum:75V AC L-N) (Crank Disconnect from
15V L-N @ 20Hz) Overspeed +14% (+24%
overshoot) Underspeed -20%
