Caution:
The return conductor for all functions (point X3) must under no
circumstances be connected to locomotive ground. Possible short
circuit! The locomotive decoder will be damaged in operation.
Tip: Before starting to program the locomotive decoder you should
connect the motor to the decoder. Otherwise there is no confirmation
signal from the central unit.
Connecting the LEDs
The function outputs of the locomotive decoder switch against decoder
ground. For that reason you must connect the cathode (-) of the LED to
the output of the relevant function.
!
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.
Fixing the locomotive decoder
After completing all connections fix the locomotive decoder with double-
sided adhesive tape, for example.
!
Caution:
The locomotive decoder can get warm during operation. For that
reason it should not be covered with shrinking hose or hot adhesive.

Caution:
When the total current consumption is more than 1,5 A you should cool
the decoder. As a heat sink you could use a SMD heat sink with a base
