Measuring the sensor
In case of an error the sensor can be checked with the help of an ohmmeter. In order to do so, the sen-
sor must be disconnected from the power and the ice and snow detector. The values in the following
tables show the resistance values of the sensor units.
Resistance values of the temperature unit:
After the sensor cables connected to the T1 und T2 terminals have been disconnected, the temperature
unit can be checked at the wire end ferrules. The measurement must be done between the white and
white/black wires (or between blue and brown) of the sensor.
The following table shows the comparison values from temperature to resistance for a functional tem-
perature unit.
Resistance values of the moisture unit:
After the sensor cables connected to the M1 und M2 terminals have been disconnected, the moisture
unit can be checked at the wire end ferrules. The measurement must be done between the red and red/
black wires of the sensor. For a functional moisture unit the resistance value is:
