3.3 Fitting the sensor
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.
The TW-31 has been designed for connection to various types of sensor (see tech-
nical data). It can function properly only if one of those sensor types is installed and
the parameters are correctly set.
When setting the tank monitor parameters (and whenever the sensor is replaced)
the “actual value correction” [Parameter C91] must be adjusted so that the temper-
ature measured corresponds to that shown on the display. A reference thermometer
should be used for this purpose.
See the section 8.7
Pay attention to the permitted temperature range for sensor cable exposure.
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. See section 8.7
3.4 Cleaning instructions
The enclosure front (front foil) can be cleaned with usual detergents.
ATTENTION: The enclosure front is not resistant to aggressive acids
and alkalis, abrasive cleaners and cleaning with high-pressure clean-
ers.
The use of these cleaners and cleaning methods may lead to damages!
