Pin-Assignments and Description of the Thermistor-Pinheaders. The pictures are in the
same view than the overview picture.
Warning
: For improved EMI noise immunity the leads of the thermistors must be kept
floating. The GND-Pins of the PT100 can be used for shielding. Shielding
must be kept single ended, too.
Remark
: The targeted value for the NTC is 10k (Factory set). If you need 1k NTCs or a
low temperature, switch from 10k to 1k via software command.
