Funct. Activation / Deactivation Activated / Deactivated Activated
The Irradiation switch function can be used for operating a relay depending on
the measured irradiation value.
The allocated relay is switched on if the adjusted irradiation value remains exceed-
ed for the adjusted duration. If the irradiation falls below the adjusted value for the
adjusted duration, the relay is switched off.
If the Inverted option is activated, the relay operates vice versa.

Funct. Activation / Deactivation Activated / Deactivated Activated
The Error relay function can be used for operating a relay in the case of an error.
Thus, e. g. a signalling device can be connected in order to signal errors.
If the error relay function is activated, the allocated relay will operate when a
sensor fault occurs.
