How Alarm is Set
Condition 1
If on the first engine start after clearing an Alarm Code 44, the fuel pressure switch indicates low fuel pressure for
10 seconds after a successful engine start, the following occurs:
•
Engine goes to high speed for 2 minutes.
•
If the 2 minutes is exceeded and fuel pressure is low, set Alarm Code 44 as a shutdown alarm.
•
If fuel pressure is good after 2 minutes, activate condition 2 and return to normal operation.
Condition 2
This condition does not apply if condition 1 is active.
If the engine is running and the fuel pressure switch was indicating good fuel pressure and is now indicating low
fuel pressure for 15 seconds set Alarm Code 44 as a Shutdown alarm.
How Alarm is Cleared
This alarm is cleared manually
Considerations
This alarm becomes a log alarm if the unit is switched to electric operation.
This alarm is only active if the unit is equipped with a low fuel pressure switch.
Diagnostic Procedure
1. Check the fuel level.
2. Check for loose fuel lines and/or air in the fuel lines.
3. Check for gelled diesel fuel when operating in extremely cold conditions.
4. Check fuel pressure switch and connections.
