Caution:
The return conductor for all functions (point X1 or X6) must under no
circumstances be connected to locomotive ground. Possible short
circuit! The locomotive decoder will be damaged in operation.
Tip:
If the second side of the lamps is connected to locomotive ground
the lamps often flicker in operation. You can avoid the flickering of the
lamps if you connect the second side to the return conductor (point X1
or X6) instead of locomotive ground.
Caution:
If you connect the lamps to the return conductor for all functions (point
point X1 or X6), the lamps must be insulated. The lamps must not
make contact with metal parts of the locomotive. Possible short circuit!
The locomotive decoder will be damaged in operation.
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. There are LEDs with 2-5
mA, but also LEDs with 15-30 mA power consumption. 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.
