* Self-Diagnosis Error Description
When the Failure Condition occurs, the Compressor will immediately stop if the Compressor is running
and there will be a 5 minute
standby. During the 5 minute standby, RPM signals will be ignored. That is,
even though the Inverter PBA receives the RPM
signals, the Compressor does not work.
