This message indicates the leaving and return chilled
liquid temperatures at the time of the fault.
This message indicates the leaving hot liquid tempera-
ture at the time of the fault on units with water cooled
condensers.
This message displays the programmed chilled liquid
setpoint and deviation (control range) programmed at
the time of the fault.
This message indicates the outdoor ambient air tem-
perature at the time of the fault.

This message indicates which refrigerant system was
in the lead at the time of the fault.
This message indicates the status of the evaporator
pump signal from the microprocessor.
This message indicates that a remote device such as a
Remote Control Center, an ISN controller, or another
device sending a PWM signal for temperature or cur-
rent reset is overriding control points programmed
through the keypad or default microprocessor setpoints.
System Data:
Following the common data is a sequence of system
messages, which are repeated for each refrigerant sys-
tem. These messages display system parameters at the
time of the fault:
• Compressor status (ON or OFF)
• System run time since the last compressor start
(in Days, Hours, Minutes, and Seconds)
• Compressor motor current
(as a percentage of FLA)
• System differential oil pressure, suction pressure
and discharge pressure
• System oil temperature, suction temperature and
discharge temperature
• Compressor suction gas saturation temperature and
superheat
• Compressor discharge gas saturation temperature
and superheat
• Compressor slide valve position (Step 0 = mini-
mum capacity, Step 75 = fully loaded)
• Refrigerant temperature at the inlet of the cooler
Liquid line solenoid valve and oil cooling solenoid
valve, when fitted, position (ON = e n e r g i z e d ,
OFF = de-energized)
• Stage of condenser fan operation (remote air cooled
condenser if fitted) and status of the compressor
heater
• Wye-Delta timer output.
