Status / Error message
Possible cause
Correction
A31
Excess current inverter
Current too high due to sudden changes in load, short-circuit in motor line, incorrect parameter settings.
Please contact your authorised Webasto Marine dealer.
A32
Phase connection compres- sor 1
Compressor, phase connection. Break in compressor connection cable.
A33
Earth leakage current
Earth fault found. Earth current too high.
A34
Excess current inverter
HW excess current. Current too high due to sudden changes in load, short-circuit in compressor connection line, incorrect inverter param
-
eter settings.
A35
DC-Bus inverter
DC bus fault. No input voltage at power supply.
A36
Undervoltage inverter PFC
Undervoltage “power factor correction”. Insufficient power supply.
A37
Undervoltage inverter
Undervoltage due to low supply voltage or defective inverter.
A38
Compressor speed 1
Incorrect speed or incorrect parameters at too high a load.
A39
Cable bridge inverter
Compressor 1 switched off because the input is not bypassed/open. Cable not connected. Function of external relay, 24V voltage not applied.
A40
Compressor 1 overload
Maximum permissible current was exceeded within the defined time window.
A41
Overvoltage
The DC voltage of the intermediate circuit has exceeded the maxi- mum permissible value as the result of excessively long delay or over- voltage peaks in the supply voltage.
A42
Under temperature inverter
Temperature in inverter below permissible level.
A43
Excess temperature com- pressor 1
The measured PTC thermistor temperature corresponds to a resist- ance >2600 ohm.
A44
IGBT inverter
Internal fault.
A45
CPU inverter
CPU fault. Data loss in memory.
A46
Parameter inverter
Parameters were reset automatically to factory setting: User-specific parameter setting corrupted.
A47
Data communication in- verter
Data communication fault. Data reception faulty.
A48
Thermistor inverter
Internal inverter thermistor fault.
A49
Automatic adjustment in- verter
Automatic adjustment faulty. Incorrect parameters.
