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.
•
Enter the Configuration mode in the controller and verify the configuration for the
Start output. Check that the Start output is working correctly by measuring its
output voltage.
•
Enter the Configuration mode in the controller and verify the configuration of the
Crank disconnect method. Verify the configuration of the LLOP Switch polarity.
Ensure that the lube oil pressure switch and sensor are working OK. Check their
wiring.
The Emergency Stop alarm is shown
without the Emergency Stop is activated.
•
Check if the Emergency stop switch is working OK, including the wiring.
•
Enter the Configuration mode in the controller and verify the configuration of the
Emergency stop polarity.
The controller generates unnecessary
Shutdown alarms or Warning alarms.
•
Check the respective switch, sensor and wiring.
•
Enter the Configuration mode in the controller and verify the respective threshold
configuration.
The controller shows 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
~30 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. Press and hold the
Stop/Config
button during a power cycle to reset the
controller.
2. Re-send the configuration file.
The controller sends a Crank-start
command immediately after power on.
•
Ensure 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 suitable controller terminal.
•
Enter the Configuration mode in the controller and verify the configuration for Start
mode and the Start relay output polarity.
