below the pre-set value, it will initiate a shutdown alarm.
4
Loss of Speed Signal
When the controller detects that the engine speed is 0 and the
action select “Shutdown”, it will initiate a shutdown alarm.
5
Gen Over Frequency
When the controller detects that the genset frequency has
exceeded the pre-set value, it will initiate a shutdown alarm.
6
Gen Under
Frequency
When the controller detects that the genset frequency has fallen
below the pre-set value, it will initiate a shutdown alarm.
7
Gen Over Voltage
When the controller detects that the generator voltage has
exceeded the pre-set value, the controller will initiate a shutdown
alarm.
8
Genset Under
Voltage
When the controller detects that the genset voltage has fallen
below the pre-set value, it will initiate a shutdown alarm.
9
Fail To Stop
If the engine does not fire after the pre-set number of attempts, it
will initiate a shutdown alarm.
10 Gen Over Current
