Includes all shutdown alarms and warning alarms. Warning alarms are
not self-latching, while shutdown alarms are self-latching 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 idles. 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 powered on.
During normal operation of the generator, closes the breaker.
Output when entering high speed warming up and disconnect after high
speed cooling.

High Temperature Cooling
Shutdown
When the genset is working normally and this signal is
activate, 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 genset
without cooling down.
