The compressor discharge temperature
exceeded 199.4?F (without oil cooler) or
230ºF (with oil cooler). This diagnostic will
All be suppressed during Stopping mode or
[compressor after the compressor has stopped. Note:
run unload or As part of the Compressor High
compressor not Temperature Limit Mode (aka Minimum
running] Capacity Limit), the compressor shall be
forced loaded as the filtered discharge
temperature reaches 190ºF (without oil
coolers), or 220ºF (with oil coolers).
GP2 Cprsr: The differential pressure for
the respective circuit was above 275 Psid
Cprsr
Energized (1890 kPa) for 2 consecutive samples 5
seconds apart.
The evaporator refrigerant pressure of
either circuit has risen above 190 psig. The
evaporator water pump relay will be de-
energized to stop the pump regardless of
why the pump is running. The diagnostic
will auto reset and the pump will return to
normal control when all of the evaporator
All pressures fall below 185 psig. The primary
purpose is to stop the evaporator water
pump and its associated pump heat from
causing refrigerant side pressures, close to
the evaporator relief valve setting, when
the chiller is not running, such as could
occur with Evap Water Flow Overdue or
Evaporator Water Flow Loss Diagnostics.
