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