automatically after 10 minutes; if the failure occurs 3 times in 2 hours, it indicates that the
INV compressor is faulty. The unit needs to be turned on and reset after temporary power
disconnection;
b When failure occurs to two INV compressors at the same time, the unit will
automatically turn off to prevent damages. After the power is resumed, reset the unit.
3.4 Current protection of inverter compressor
The unit’s compressor drive module detects the compressor operating current and hence
to provide feedback. See details below
E655DHD:
When I(INV) ≥ 22A for 4s, the corresponding INV compressor sends compressor current
overload protection alarms (remove error data after 5 minutes) and the unit recovers after
10 minutes; if compressor error is reported 3 times in 2 hours, the compressor cannot turn
on. The unit needs to be restarted after temporary power disconnection. If all the
compressors of the unit send alarms, the unit will automatically turn off to prevent
damages.
