Cprsr Energized High Vi Cprsr: The differential pressure for the
respective circuit was above 275 Psid (1890 kPa) for 2
consecutive samples or more than 10 seconds.
Low Vi Cprsr: The system differential pressure was
above 188 Psid (1296.4 kPa) - for 2 consecutive
samples or more than 10 seconds.

The pressure ratio for the respective circuit exceeded
5.61 for 1 contiguous minute while in service
pumpdown. This pressure ratio is a fundamental
limitation of the compressor. The pressure ratio is
defined as Pcond (abs)/Pevap(abs).

The compressor discharge temperature exceeded 200°F
(without oil cooler) or 230ºF (with oil cooler). This
diagnostic will be suppressed during Run-Unload or after
the compressor has stopped. Note: As part of the
Compressor High Temperature Limit Mode (aka
Minimum Capacity Limit), the compressor shall be
forced loaded as the filtered discharge temperature
reaches 190ºF(without oil coolers), or 220ºF (with oil
coolers).

While Running Normally, the Discharge Superheat was
less than 12 degrees F +- 1F for more than 6500 degree
F seconds.. At circuit startup the Discharge Superheat
will be ignored for 5 minutes.
