- ECM Selector Switch in Alternate Position (301)
- ECM Fault (304)
- Engine Fuel Injection Malfunction (302)
- PLD Low Suction Pressure (305)
- High Raw Water Temperature (310)
- Low Raw Water Flow (311)
- Battery Failure 1-2
- DC Failure
- Over Pressure
Pump Room Trouble. Activated when one or more of these conditions are active :
- Fuel Tank Leak
- Low Fuel Level
- High Fuel Level
- AC Failure
- Low Pump Room Temperature
- Low Suction Pressure
- Water Reservoir Low
- Water Reservoir Empty
CTRL Trouble: Important: this relay is normally energized when the controller is in normal condition. The relay is
de-energized when controller trouble is detected (fail safe). Activated when one or more of these conditions are
active :
- Charger Failure 1-2
- DC failure
- Default Solenoid Valve
- Weekly Test Cut-In Not Reached
Regular alarms list:
- AC Failure: Monitors the AC power and activates on a failure.
- DC Failure: Monitor the DC power from the batteries and activates if both batteries fail.
- Battery 1-2 Fail: Monitors the status of batteries and activates on a failure. This occurs when the battery is
disconnected, is of the wrong type or is unable to be recharged.
- Charger 1-2 Fail: Monitors the state of battery chargers and activates on a failure. This occurs when the battery
charger has a defect, is not properly powered, or is unable to provide the needed current. The charger will also
change to Boost Fault mode if during a boost test, the voltage does not rise. A NC dry contact is also connected
from the charger to the IO Board. The alarm will activated if this contact open for the time set on the Charger Fail
alarm page. Charger readings are not updated during cranking and/or running, due to reading instability under load.
As soon as the engine returns to an idle state, all readings and failure analysis are reactivated.
- Service Required: Activates when service is due for the controller. This occurs when the date set in the service
page has passed, or if no service has ever been done.
- Weak Battery 1-2: Activates if the battery voltage falls below the weak battery factory set point.
- Loss of Continuity 1-2: Activates if the engine start contactors are disconnected from the controller.
- Weekly Test Cut-In Not Reached: Activates if the Cut-In is not reached during a manual or a weekly run test. At
the end of the 20s timer, if the Cut-In is not reached, the test may still be successful at starting the engine if the
pressure has dropped by at least 5 PSI.
- Check Weekly Test Solenoid: Activates if the pressure does not drop a minimum of 5 PSI during the manual run
test or the weekly test. Indicates a failure with the Test Solenoid Valve.
