TROUBLESHOOTING
Alarm List Check
Where there are problems in the system operation, you need to review the alarm list menu of the controller and then
check the engine and the system in reference to the alarm codes.
1) When problems described in alarm codes E03, E04, E07 or E08 occur, the engine is not available for safe operation
and therefore the engine will stop as the controller will turn off the actuator for safety.
2) When problems described in alarm codes E03, E04, E07 or E08 occur, the engine will not be able to restart as long as
the alarm is not released.
3) When alarms occur, you can release them by turning off the power of the controller.
