Using the Bluetooth technology, the transmitter and receiver do not need visual contact with a range of several meters.
Subsequently, even after decoupling, the outputs are still controlled and switched on.
Using a magnetic sensor this drawback can be solved. In this case the Bluetooth connection is only built up, when a magnet is near the sensor.
The magnetic sensor must be activated in the LM-Teacher.
At a semitrailer the magnet is fixed below the fifth wheel.
