LC
PCB mismatching
Defective radiation fin thermistor
Transmission error
Compressor
Instantaneous overcurrent of inverter
compressor (When inverter output
current exceeds 460V units: 32.3A
230V units: 59.1A even
instantaneously)
For 460V units
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.
For 230V units
A current of 33.5A or
more continues for a
period of consecutive 5
sec.
A current of 27.6A or
more continues for a
period of consecutive 260
sec.
Defective startup of
inverter compressor
(Compressor stops
running immediately
after it starts up.)
Defective radiation inverter
When transmissions
between the main PCB
and the inverter PCB
are not normal
Weak-current
part
Heavy-current
part (Power
transmission etc.)
When
imbalance in
voltages among
three phases
comes to 2% or
more
When the radiation fin
thermistor resistor detects an
open circuit (-30˚C or less) or a
short circuit (120˚C or more)
When the
radiation fin
temperature
reached 87˚C or
more
Inverter compressor lock
(Compressor does not
run at all.)
When incorrect
inverter PCB is
connected
Inverter
PCB
When the power
supply voltage
falls out of the
range of
460VAC±10%
230VAC±10%
When the radiation heavy
current part of inverter gets
defective (gives no output)
