62-11640 7–4
00011 CHECK ENGINE OIL PRESSURE
NOTE
This alarm may be activated if too high a viscosity oil is used in cold ambient.
• ACTIVATION: The ENCU circuit is energized (3MM−9) and engine oil pressure is below 12 psig (0.82 bar)
for longer than 5 seconds while the engine is running.
• UNIT CONTROL: Engine Operation: Shutdown and alarm.
Electric Operation: Will not activate in electric operation.
• RESET CONDITION: Auto reset or alarm may be manually reset using the display mounted keys or by
turning the unit off, then back on again.
NOTE: Follow the Troubleshooting steps until a problem is found. Once a repair or correction has been made, clear
the active alarm(s). (Refer to Note 1 in Notes Section, page 7-2.) Operate the unit through the appropriate modes
to see if any active alarm occurs.
CORRECTIVE ACTIONS:
1. Check Engine Oil Level
Check engine oil dipstick. Add engine oil as needed to fill.
2. Check Engine Oil Pressure Switch (ENOPS) Power & Wiring
a. Inspect switch, connector pins & terminals. Verify that there is no physical damage to the switch.
Check the connections for damage and corrosion.
b. Using Component Test Mode, energize the ENCU Power Circuit. Check for power at the switch con-
nector. Must have minimum 11 VDC. If not, check the connectors and wiring between terminals for
damage, moisture or corrosion.
c. Check for continuity from switch connector terminal A to ENCU−15. If good continuity is not present,
check connectors and wiring between terminals for damage, moisture or corrosion.
d. Check for continuity from switch connector terminal B to ENCU−18. If good continuity is not present,
check connectors and wiring between terminals for damage, moisture or corrosion.
3. Check ENOPS Switch
Remove switch, connect to an external pressure source and test. Contacts close on a pressure rise at
15 psig (1.02 bar). Contacts open on a pressure fall at 12 psig (0.82 bar).
4. Check Engine Oil Pressure
Connect mechanical oil gauge. Oil pressure must be greater than 15 psig (1.02 bar.).
