Options for identifying faults in the Altivar 12 frequency converter
If error message E03.xxx is present on the combi steamer, this may mean that the frequency
converter has detected a fault with itself, with the fan motor or with the motor cable. The frequency
converter indicates a fault by a flashing error code in the display (41).
The cause of the fault must be rectified before the frequency converter is reset. All faults can
be reset by disconnecting the frequency converter from the power supply for two minutes and then
switching it back on. The display will show the message "rdY" if there are no other faults present.
The following table summarizes the indications given by the display of the frequency converter
(Altivar 12) when there is a fault but no error message:
