Malfunction
Decision
Conditions
A position signal error occurs while the compressor is running.
A speed error occurs while the compressor is running.

microcomputer.
The system will be shut down if the error occurs 255 times.
Clearing condition: Continuous run for about 10 minutes (normal)
Supposed
Causes
Over-current due to defective power transistor
Over-current due to wrong internal wiring
Over-current due to abnormal supply voltage
Over-current due to defective PCB
Error detection due to defective PCB
Over-current due to closed stop valve
Over-current due to compressor failure
