Inverter compressor lock
(Compressor does not run at all.)
PCB mismatching
When incorrect inverter
PCB is connected
Imbalanced power supply voltage
When imbalance in
voltages among three
phases comes to 2%
or more
Power supply voltage error
When the power supply
voltage falls out of the
range of 400VAC±10%
Radiator fin temperature rise
When the radiator fin
temperature reached
93˚C or more
Faulty fin thermistor
When the fin thermistor resistor detects
an open circuit (-30˚C or less) or a short
circuit (120˚C or more)
Transmission error
Overcurrent of inverter compressor
When transmissions between the
main PCB and the inverter PCB
are not normal

When the heavy current part of
inverter gets faulty (gives no output)
Instantaneous overcurrent of inverter compressor
(When inverter output current exceeds 32.3A
even instantaneously)
An overcurrent of 19.0A or more continues
for a period of 5 consecutive seconds
An overcurrent of 16.1A or more continues
for a period of 260 consecutive seconds.
Faulty startup of inverter compressor
(Compressor stops running
immediately after it starts up.)
