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: 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)
instead of locomotive ground.
Advice: Before starting to programm the locomotive decoder, you
should connect a lamp to at least one of the function outputs X4 to X6,
as the beginning of the programming mode as well as the entering of
the set parameters is indicated by flashing the locomotive lighting.
Advice: Some accessories can not be checked for operation by
switching on and off in short invervals (e.g. smoke generators). If you
have connected accessories like these to the function outputs X4 to X6
of the decoder it is recommended to connect a lamp in parallel to the
accessory during the programming of the decoder.
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.
