If the overflow prevention is deactivated [OP] = [OFF] or [MedI] = [Auto], the
reliable function of the sensor must be verified with particular care. Switch-
on and switch-off processes and special operating states such as very full
tanks, possible maintenance and cleaning operations are to be considered
in the verification.
For the setting [OP] = [OFF], the menu item [cOP] is not available.
