The temperature sensor motor protection function measures the motor's stator
winding temperature directly using a measuring sensor in the motor, i.e. this
requires a motor with a measuring sensor wound into the stator winding.
Two different types of measuring sensors are available for the evaluation.
• PTC thermistors type A ("type A sensors")
• Thermo click
The wiring and the sensors are checked for wire breaks or short circuits.
