4. Technical Data
4.2 Fitting the sensor
When setting the temperature controller parameters (and whenever the sensor is
replaced) the “actual value correction” [Parameter C91] must be adjusted so that the
temperature measured corresponds to that shown on the display. A reference thermo-
meter should be used for this purpose.
Pay attention to the permitted temperture range for sensor cable exposure.
40 mm
The sensor cable must not be chafed or kinked.
There must be no substantial mechanical pressure on the sensor tube.
Do not place the sensor and the high-voltage cable in the same cable
conduit (not even within the switchbox).
Temperature range sensor cable -10°C .. +70°C
Changing the sensor cable length
lf it is necessary to shorten or lengthen the sensor cable on installation (or if a sensor
other than the one supplied is to be fitted), the "actual value correction" parameter
must be adjusted accordingly.
