General troubleshooting
Fault
Action
The controller does not power ON.
• Check the battery voltage.
• Check the fuse on the battery supply.
• Check continuity between battery positive and controller terminal 2.
• Check continuity between battery ground and controller terminal 1.
The controller display freezes or hangs
up.
• Reset the controller power.
The controller fails to crank-start the
engine.
• Check the battery voltage.
• Go to the Configuration menu on the controller. Make sure the start output is
configured correctly. Measure the output voltage to make sure the output is
working.
• Go to the Configuration menu on the controller. Make sure the crank
disconnect method and the LLOP switch polarity are configured correctly.
Make sure that the lube oil pressure switch and sensor are working correctly.
Do a check of the wiring for the switch and sensor.
The emergency stop alarm is shown
when the emergency stop is not
active.
• Check if the Emergency stop switch is working correctly. Make sure to also
do a check of the wiring for the switch.
• Go to the Configuration menu. Make sure the emergency stop polarity is
configured correctly.
The controller incorreclt shows
shutdown or warning alarms.
• Check the switch, sensor and wiring.
• Go to the Configuration menu. Make sure the threshold is configured
correctly.
The controller shows a charge fail
alarm.
• To check if the controller's charging alternator terminal is working:
◦ Disconnect the charging alternator wiring to the controller's terminal 7.
◦ Short terminal 7 to the ground through a DC ammeter.
◦ Crank-start the engine.
◦ The DC ammeter should indicate the current in the range of 200 to 400
mA for seconds.
◦ If yes, the controller's charging alternator terminal is working OK.
• Disconnect and re-connect the charging alternator ind connection to the
controller's terminal 7.
• Check if the charging alternator is working OK.
The controller shows error C03.
Error C03 can occur if the controller is disconnected from the PC during a
configuration.
1. Push and hold the Stop/Config
button during a power cycle to reset the
controller.
2. Send the configuration file again.
The controller sends a crank-start
command immediately after power on.
• Make sure that the controller's output terminal is not directly connected to
the starter relay. The controller's output should be given to an intermediate
relay which should in-turn power the starter relay. The controller can get
permanently damaged and will need to be replaced if this precaution is not
taken.
• Check start-relay connection with the corresponding controller terminal.
• Go to the Configuration menu on the controller. Make sure that the start
mode and polarity for the start relay output are configured correctly.
