*1)
If this error is detected, the device will lock electronically and a standard error ac-
knowledgment is not possible any more. In order to acknowledge this error, the device
has to be disconnected from the power supply after removal of the cause of the error.
*2)
If this error is detected, the device will lock electronically. In order to acknowledge
this error, the input IN 2 has to be switched off.
Note:
If several errors are detected, the first error remains in a pending state until
the errors have been eliminated.
