HGM1780 Automatic Genset Controller
6.3 DEFINITION OF DIGITAL INPUTS (ACTIVE WHEN CONNECT TO
GND (B-)) (TABLE 3)
6.2 DEFINITION OF RELAY OUTPUTS (TABLE 2)
Includes all shutdown alarms and warning alarms. Warning
alarms are not self-latching, while shutdown alarms are and will
not disappear until they are reset.
Suitable for the genset with stop electromagnet. The
electromagnet closes when stop idle is over. And opens when
EST delay is over.
Used for machines that have idle mode. Closes during
cranking, disconnects during warming up, closes during stop
idle delay, disconnects after complete stop.
It closes before starting and opens before starter is power on.
During normal operation of the generator, closes the breaker
If these signals are activated after crank
disconnect, shutdown alarm will be
immediately initiated.
Only warning and not stops if this input is
active.
Shutdown alarm will be immediately
initiated if this input is active.
High Temperature
Stop Input
When the gen-set is working normally and
this signal is activated, if there is a high
temperature situation, the controller will first
cool down the generator and then stop it; if
the signal is deactivated and a high
temperature situation occurs, the controller
will shut down the gen-set without cooling
down.
