Factory settings
If you want to use the factory settings, you have to connect the lighting
and the accessories as follows:
Front lighting: AUX1
Back lighting: AUX2
Connecting the LEDs
The function outputs of the module (AUX1 and AUX2) switch to the
module ground. For that reason you must connect the cathode (-) of
the LED to the function outputs.
!
Caution:
If you use light-emitting diodes (LEDs) you must always operate them
via a series resistor. LEDs are available in many different models. The
series resistor limits the current flow of the LED and will need to be
calculated for each model. Ask for the max. current rating when buying
your LEDs.
You can connect several LEDs in parallel to each output. In this case
every LED must have a series resistor of its own. If you connect several
LEDs to one output in series, only one series resistor is needed.
Connecting a smoothing capacitor
In track sections with bad contacts the power supply may be
interrupted shortly. You can solder a capacitor (e.g. 100 µF/35 V)
between the points X3 and X6 to conterat this effect (see fig. 1).
Fixing the module
After completing all connections fix the module with double-sided
adhesive tape, for example.
