Diagnosis
Countermeasure
Is the
Power source
voltage OK?
YES
Are the
service valves
opened?
NO
YES
Is the
high pressure
during operation
OK?
YES
Is the
checked result of
insulation resistance and
coil resistance (1) of
compressor motor
OK?
YES
(1) 0.864

Check power source.
Open the valves.
Check refrigerant amount
and refregerant circuit.
* In case of transitional
increase of high pressure
and/or test run, several
times restarting may
recover it, because liquid
refrigerant (migrated)
in the compresser is
discharged from the
compressor.
Replace compressor.
2. Error detection method
In order to prevent from
overcurrent of inverter,
if the current exceeds the
specifications, it makes the
compressor stopping.
3. Condition of error displayed
• If the output current of inveter
exceeds the specifications,
it makes the compressor
stopping.
4. Presumable cause
• The valves closed
• Faulty power source
• Insufficient refrigerant amount
• Faulty compressor
• Faulty power transistor
module
