9.2.1 Operation without temperature detection
Use of the COMBIVERT without evaluation of the temperature input:
Switch off evaluation (pn12 =7) or install bridge between terminal TA1 (X1C.9) and
TA2 (X1C.10) (dr33=1).
9.2.2 Connection of a KTY sensor
ACHTUNG
No protection of the motor winding in case of wrong connection!
Non-observance leads to incorrect measurements and possibly to the de-
struction of the motor winding
a) Operate KTY sensors in forward direction.
b) KTY sensors may not be combined with other detections.
