if current of DC motor driving board is over 5A, unit
alarms. 2 minutes and 50 seconds later after unit
stops, resume automatically, if it occurs three times in
an hour, confirm the failure.
if voltage of DC motor driving board is below 280V,
unit alarms. 2 minutes and 50 seconds later after unit
stops, resume automatically, if it occurs three times in
an hour, confirm the failure.
if voltage of DC motor driving board is over 400V, unit
alarms. 2 minutes and 50 seconds later after unit
stops, resume automatically, if it occurs three times in
an hour, confirm the failure.
fan motor rate can not be detected. 2 minutes and 50
seconds later after unit stops, resume automatically, if
it occurs three times in an hour, confirm the failure.
fan motor rate is higher than 1100 for 5 seconds, unit
alarms.
IPM modular over current, in short circuit, over heat,
voltage too low of control circuit.
in the course of compressor startup or running, the
unit can not detect the rotor position, or not connecting
compressor.
radiator temp. too high
output current of transducer is too high
voltage of power source is too low
voltage of power source is too high
communication is disconnected
