The intermediate oil pressure
transducer for this compressor
was out of the acceptable
pressure range for 15 seconds,
while the Delta Pressure was
greater than 2.45 bar:
Acceptable range is 0.50 > (PC-
PI) / (PC-PE) for the first 2.5
minutes of operation, and 0.25
> (PC-PI) / (PC- PE) thereafter

a. The Suction Refrigerant
Pressure (or either of the
compressor suction pressures)
dropped below 0.7 bar just
prior to compressor start (after
EXV preposition).
b. The pressure fell below 1.12
bar while running after the
ignore time had expired, or fell
below 0.7 bar (or 0.35 bar in
software prior to Oct 02) before
the ignore time had expired.
The ignore time is function of
outdoor air temperature. Note:
Part b. is identical to Low
Evaporator Refrigerant
Temperature diagnostic except
for the trip integral and trip
point settings.
