The intermediate oil pressure sensor for
this compressor was out of the acceptable
pressure range for 15 seconds, while the
Delta Pressure was greater than 15 Psid
(172.4 kPa).: Acceptable range is 0.50 >
(PC-PI) / (PC-PE) for the first 2.5 minutes
of operation, and 0.28 > (PC-PI) / (PC-PE)
thereafter.

The respective Evaporator Refrigerant Pool
Temperature dropped below the Low
Refrigerant Temperature Cutout Setpoint
for 2250°F-sec (12°F-sec max rate for
early circuit startup period) while the
circuit was running. The minimum LRTC
setpoint is -5°F (18.7 Psia) the point at
which oil separates from the refrigerant.
The integral is held nonvolatile though
power down, is continuously calculated,
and can decay or build during the circuit off
cycle as conditions warrant.

a. The Suction Pressure dropped below 10
Psia just prior to compressor start (after
EXV preposition). b. During Early Startup
Period: the Suction Pressure fell below a
pressure equal to Condenser Pressure ÷ 8
but as limited to not less than 6 or greater
than10 psia. c. After Early Startup Period
expires: The Suction Pressure fell below 16
Psia.
(Note: the Early Startup Period is between
1 and 5 min as an inverse function of the
Cond Temp measured at time of circuit
startup).

The main processor has successfully come
out of a reset and built its application. A
reset may have been due to a power up,
installing new software or configuration.
This diagnostic is immediately and
automatically cleared and thus can only be
seen in the Historic Diagnostic List in

Circuit
The system differential pressure was
below 7.7 Psid (53 kPa) for 6 seconds after
the 11 seconds ignore time relative to
cprsr/circuit startup had expired. In a two
compressor circuit, the lower of the two
suction pressures is used for DP.

respective Suction Pressure 10 Psia or
more for 30 seconds continuously.
