Failure code
Failure description
definition
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, confirm the failure.
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, confirm
the failure.
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, confirm the
failure.
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, confirm the failure. After fixed
frequency compressor alarms, inverter compressor will
continue to run. If fixed frequency compressor has been
locked for 3 times, the unit will stop and alarm.
No communication within 30 seconds continuously
3 minutes after recovery
Cannot receive valve plate module signal in 200 continuous
rounds or receive wrong data,recover automatically when
received right data.
Communication failure between valve plate module and
host computer
Tc1 temp. sensor cannot connect with valve plate module
Tc2 temp. sensor cannot connect with valve plate module
