Overview of possible operating and error messages
If an error occurs, the motor switches off permanently. Exception error: "Undervoltage". The motor automati-
cally switches back on as soon as the voltage lies over 209V for at least 6 seconds.
If an error occurs, the system must be disconnected from the power supply and the motor must be reset.
An overview of possible error codes will help to determine the fault.
