Failure description Remarks
39-1 39-1
Compression ratio
too high protection
After compressor is running, compression ratio 8. for
continuous 5 minutes stop and alarm.2 minutes and 50
seconds later, resume automatically, if it occurs 3 times in an
hour, conrm the failure.
Once
conrmation,
un-resumable
39-2 39-2
Compression ratio
too low protection
In normal operation, compression ratio <1.8 for continuous 5
minutes stop and alarm.2 minutes and 1 seconds later,
resume automatically, if it occurs 3 times in an hour, conrm the
failure.
Once
conrmation,
un-resumable

High pressure
sensor Pd too high
protection
In normal operation, Pd>=4.15Mpa for continuous 50ms, alarm
and stop. 2 minutes and 50 seconds later, resume
automatically, if it occurs 3 times in an hour, conrm the failure.
Once
conrmation,
un-resumable

Discharging temp.
sensor Td too low
protection
In normal operation, if Td<CT+50°F(10
) for continuous 5
minutes, the unit stops and alarms.2 minutes and 50 seconds
later, resume automatically. If it occurs 3 times in an hour,
conrm the failure. After xed frequency compressor alarms,
inverter compressor will continue to run. If xed frequency
compressor has been locked for 3 times, the unit will stop and
alarm.
