Low Oil Pressure OILPD [VALUE] exceeded l imit
of [LIMIT]*. Check oil pump sys-
tem.
Check for closed oil s upply valves.
Check oil filter. Check for low oil tem-
perature. Check transd ucer accuracy.

Oil Press Sensor
Fault OILPD [VALUE] exceeded limit
of [LIMIT]*. Check oil pressure
sensor.
Check for excessive refrigerant in oil
sump. Run oil pump manuall y for 5 min-
utes. For hermetic compressors, check
both oil pressure and co oler pressure.
For open-drive units, check calibration
of oil pressure diffe rential amplifier
modules. Check wiring. Replace trans-
ducers if necessary.
