The evaporator refrigerant
pressure of either circuit has
risen above 13.3 bar. 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 pressures fall below
13 bar. This diagnostic has
severity of Immediate because
if an evaporator pressure reads
high without being invalid, the
pump would be shut off but the
chiller could keep running.
Evaporator water flow
diagnostics are not active if the
pump is commanded off, only
if the pump is commanded on
but flow does not occur as
expected.

The respective oil temperature
as supplied to the compressor,
exceeded 93°C for 2
consecutive samples or for
over 10 seconds. Note: As part
of the Compressor High
Temperature Limit Mode
(Minimum Limit), the running
compressor's female load step
will be forced loaded when its
oil temperature exceeds 88°C
and returned to normal control
when the oil temperature falls
below 77°C.
