Settings
Output signal transmitter (optional): A passive piezo signal
transmitter can be connected to the connector strip (pin BUZ and
GND). The status of the signal (acoustic signal at dry or wet) can be
set with jumper S1-S2 or S2-S3. In the default position S2-S3 the
signal transmitter is inactive when it rains.
Switching behavior: The switching behavior of the relay (energised
or de-energised in rain) can be set with the jumper of T1-T2 or T2-
T3. In the factory setting the jumper T1-T2 is plugged in and the relay
picks up when the sensor surface becomes wet.
Heating: The sensor surface is heated if the bridge of HZ1-HZ2 is
plugged in. To ensure faster drying and for use below freezing, the
heater should be switched on. The heater can be switched off to
detect fog.
Sensitivity setting: The sensitivity of the humidity signal can be influenced at the potentiometer. A higher sensitivity
is achieved by turning the potentiometer axis counterclockwise (right = high sensitivity, left = low sensitivity). The
middle position is most suitable for normal rain signaling. Note that there is no function at the end stops!
Loosen the cover screws of the sensor, unlock the plug connector of the sensor cable and put the cover aside first.
This will prevent damage to the sensor connection cable during the following steps. Mount the cable gland to the
housing.
