Installation in a driving cab vehicle with polarity-dependent light changes
Driving cab vehicles with direction-dependent light changes are normally designed so that
the direction-dependent switchover of the lighting (white/red) in analogue mode is performed
automatically via the respective applied polarity. Depending on the polarity, the white or red
light is switched on: If in a forwards motion, the positive pole is located on the right track, the
white light is switched on, if the negative pole is located on the track, the red light is switched
on.
In order to make the conversion of these types of driving cab vehicle particularly easy, the outputs A
and B of the LF100XF were designed so that you can simply switch the LF100XF between the
wheels and the electronics of the driving cab vehicle. Outputs C and D are then available for further
functions, e.g. the internal lighting of the coach.
