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.
