Meaning
Protection circuit
Inverter connected or GTR
in short-circuit (short
period of 0.8 sec or less)
in the Inverter check
Defect in the power supply
Compressor defect
Compressor inverter
defect
MDC defect
The compressor does not
work (the overcurrent
protection was activated
some time after the re-start
of the compressor)
Compressor malfunction.
The frequency decreases
shortly after start up then it
stops
Defect in the state of the
inverter board check
Reflow probe (TD)
disconnected, interrupted
or in short circuit
Exchanger probe (C1)
disconnected, interrupted
or in short circuit
Exchanger probe (C2)
disconnected, interrupted
or in short circuit
External temperature
probe (TO) disconnected,
interrupted or in short
circuit
Aspiration probe (TS)
disconnected or in short
circuit
EEPROM defect
GB
Condition for alarm

Interruption when restarted
Interruption when restarted
Interruption of the alarm for
interruption to the power
restoration of the
power supply
Check and
connections
1. Immediate stop or
restart
2. Check the Inverter
board: cabling defect
1. Immediate stop after
restart
2. Check the Inverter
board: cabling defect
1. Thermodynamic defect
Operating in overload
2. Tightening defect
between the HIC board
and cooling radiator
3. Cooling defect of the
radiant plate
4. Check external board
cabling
1. Compressor defect
(block, etc.): replace
the compressor
2. Power supply defect to
the compressor
(missing phase)
1. Check the power
supply voltage 200V +/
- 20V
2. Thermodynamic circuit
in overload
3. Check the CA control
circuit
The controller of the state is
activated even when the 3P
connector is disconnected
- replace the Inverter
control board
1. Check the reflow
probe (TD)
2. Connect the external
electronic board
1. Check the external
exchanger probe (C1)
2. Connect the external
electronic board
1. Check the external
exchanger probe (C2)
2. Connect the external
electronic board
1. Check the external
temperature probe
(TO)
2. Connect the external
electronic board
1. Check the aspiration
probe (TS)
2. Connect the external
electronic board
1. Check EEPROM
(IC0901)
2. Check the ME
electronic board
Condition for the
alarm signalling
Stop of the Inverter after the
defect has been detected
Alarm is displayed after 4
consecutive stops
The Inverter blocks after the
intervention of the alarm.
The alarm is displayed after
4 consecutive stops of the
Inverter
Stop of the inverter after
intervention of the alarm
Stop of the inverter after
intervention of the alarm
Stop of the inverter after
intervention of the alarm
Stop of the inverter after
intervention of the alarm
Probe defect detected (90°C
or above, 15 min after the
stop of the compressor).
(conductor interrupted)
