4.3. DIGITAL FAULT INPUT CIRCUITS
The MEC 2 Engine Controller provides four digital fault input circuits that are user
programmable. Each digital fault input circuit is activated via a remote sensing contact
that is external to the controller.
Each digital fault input circuit may be programmed with a unique fault label description
as stored in the controller’s non-volatile memory. The following digital fault labels are
provided in each MEC 2 Engine Controller:
AIR DAMPER TRIPPED HIGH OIL LEVEL
BAT CHARGER INPUT FAIL HIGH OIL TEMP
BAT CHRG TROUBLE HIGH WINDING TEMP
BREAKER TRIPPED LOW COOLANT LEVEL
DC FAIL LOW ENGINE TEMP
FAILED TO SYNC LOW FUEL PRESS
GEN BREAKER OPEN LOW FUEL LEVEL
GROUND FAULT LOW OIL LEVEL
HIGH BEARING TEMP LOW OIL PRESSURE
HIGH COOLER VIBRATION REMOTE EMERG. STOP
HIGH ENGINE TEMP REVERSE POWER
HIGH ENGINE VIBRATION BASIN RUPTURE
HIGH FUEL LEVEL ATS IN BYPASS
NO LOAD TEST FUEL LEAK
*HIGHINTKMANFTEMP LOW FUEL PRESS
VENT DAMPER FAIL BAT CHARGER FAIL
