BRAKE CONTROL AND TEMPERATURE DETECTION
4.4.2.2 Connection of a KTY sensor
NOTICE
No protection of the motor winding in case of wrong connection.
► Operate KTY sensors in forward direction. Non-observance leads
incorrect measurement in the upper temperature range.
► KTY sensors may not be combined with other detections.
