* [LIMIT] is shown on the LID as the temperature, pressure, voltage, etc., set point predefined or selected
by the operator as an override, alert, or alarm condition. [VALUE] is the actual pressure, temperature,
voltage, etc., at which the control tripped.

Stopped
CA P Emergency: Compres-
sor running without control
authorization.
Compressor is running with
more than 10% RLA and control
is trying to shut it down. Throw
power off to compressor if
unable to stop. Determine cause
before repowering.
Potential Freeze-
up
Evap Press/Temp
Too Low
ERT Emergency: Freeze-up
prevention.
Determine cause. If pumping
refrigerant out of machine, stop
operation and go over pumpout
procedures.
Failure To Stop
Disconnect Power
RUN AUX Emergency: DIS-
CONNECT POWER.
Starter and run and start con-
tacts are energized while control
tried to shut down. Disconnect
power to starter.
Loss Of
Communciation
With Starter
Loss of Communication with
Starter: Check machine.
Check wiring from PSIO to
SMM. Check SMM module trou-
bleshooting procedures.

CRT [VALUE] exceeded limit
of [LIMIT]* Emergency:
Freeze-up prevention.
The condenser pressure trans-
ducer is reading a pressure that
could freeze the water in the
condenser tubes. Check for con-
denser refrigerant leaks, bad
transducers, or transferred
refrigerant. Place the unit in
Pumpdown mode to eliminate
ALARM if vessel is evacuated.
