(1)
Check power source.
Open the service valves.
Check refrigerant amount
and refrigerant 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.
•
After 3-minute delay, the
compressor restarts, but if this
amonaly occurs 4 times within
30 minute after the initial
detection.
4. Presumable cause
• The service valves closed
• Faulty power source
• Insufficient refrigerant amount
• Faulty compressor
• Faulty power transistor
module
