Fault Finding

Symptoms

Possible Solutions

Controller no response with
power.

Check starting batteries;
Check controller connection wirings;
Check DC fuse.

Genset shutdown 

Check the water/cylinder temperature is too high or not;
Check the genset AC voltage;
Check DC fuse.

Low oil pressure alarm after crank 
disconnect

Check the oil pressure sensor and its connections.

High water temp. alarm after crank 
disconnect

Check the temperature sensor and its connections.

Shutdown Alarm in running

Check related switch and its connections according to the informa-
tion on LCD;
Check auxiliary input ports.

Fail to start

Check fuel oil circuit and its connections;
Check starting batteries;
Check speed sensor and its connections;
Refer to engine manual.

Starter no response 

Check starter connections;
Check starting batteries.

Stepping Motor Reverse

Cross connect the S11 and S12;
Cross connect the S21 and S22;
Change configuration (motor reduce direction) via PC.

GOV is out of control.

Check the speed sensor voltage is no less than 2V when cranking.
Check the connections of S11, S12, S21, S22.
