Caution:
If you connect the accessories to the return conductor for all functions
(point X1), the load must be insulated. The loads should not make
contact with metal parts of the locomotive. Possible short circuit! The
locomotive decoder will be damaged in operation.
!
Caution:
The return conductor for all functions (point X1) 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. 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 up to 5 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. The
