Engine solenoid Engine solenoid contact (Terminal 15 & 16) can be configured
in two modes
a. Mode 0: In this mode fuel solenoid contact changes from NO to close at
the time of cranking and remains close till the Genset is running. For
stopping the Generator this contact opens.
b. Mode 1: In this mode fuel solenoid contact remains open at the time of
cranking and till the Genset is running . For stopping the Generator this
contact closes for a user programmed time.
For changing the solenoid mode first press Reset button, than simultaneously
press GCB button . It’s a good practice to switch off and than switch on the
battery supply after changing the mode.
