Imbalanced power supply voltage
Power supply voltage error
Radiation fin temperature rise
Defective radiation fin thermistor
Transmission error
Overcurrent of inverter compressor
Compressor
Instantaneous overcurrent of inverter
compressor (When inverter output current
exceeds 59.1 A even instantaneously)
(1) A current of 33.5 A or more
continues for a period of
consecutive 5 seconds.
(2) A current of 27.6 A or more
continues for a period of
consecutive 260 seconds.
Defective startup of inverter compressor
(Compressor stops running
immediately after it starts up.)
Defective radiation inverter
When transmissions between the
microcomputers on the main
PCB are not normal
Low voltage
part
High voltage part
(Power
transmission etc.)
Power supply
(Single phase, 208/230 VAC)
When imbalance in
voltages among three
phases comes to 3%
or more
When the radiation fin thermistor resistor detects
an open circuit (–30°C (–22°F) or less) or a short
circuit (120°C (248°F) or more)
When the radiation fin
temperature reached
87°C (188°F) or more
Inverter compressor lock
(Compressor does not run at all.)
Outdoor
main
PCB
When the power supply
voltage falls out of the range
of 208/230 VAC ± 10%
When the radiation heavy current part of
inverter gets defective (gives no output)
