Motor Protection (Thermal Protection)
Each power-window motor is provided with its own thermal protection to prevent them from overheating. For this purpose, the motor running time is added up in a counter. The output value of the counter is influenced by the ambient temperature.
If the counter exceeds a threshold, new control requests are no longer accepted but a movement that is already in process is continued. The counter is reduced again if the motor is deactivated. Operator prompts are accepted again when the value drops below the threshold. Return window travel in the event of trapping is not obstructed by the thermal protection.
