8.2 Automatic Error Indication

The automatic error indication (alarm output) shall warn the user and guarantee a secure output in the
event of a system error. In the first place, however, its task is to switch the system off in case of a faulty
setup or a defect in the sensing head or in the electronic circuits.
Please select the desired Alarm Mode, see <Advanced Setup> in the menu <Sensor> <Sensor Setup> of
