Operating principle
The LED error display provides information on the cause of the error. After a notification by
means of a flashing signal, the error type and then the error location/error code are displayed
in each case.
The LED error display:
● Is activated during POWER ON and during operation
● Has priority over all other states that are displayed by means of the ERROR- and MAINT-
LED
● Remains on until the cause of the error has been eliminated
