PTC Temperature Sensor
The L-412.xx9025E1B is equipped with a PTC temperature sensor to prevent the motor from
overheating. The electrical resistance of the PTC temperature sensor increases considerably
into the critical temperature range. The controller must cut the power supply to the motor
(switching threshold) when the critical temperature is reached.
