Connection of LEDs as a consumer
The function outputs (AUX1 to AUX 4) are switched towards the
decoder ground. Therefore the cathode (-) of the LEDs have to be
connected to the output of the function outputs (AUX).
The anodes of the LEDs, have to be connected to the decoder
connection with the designation
‘+'.
Attention:
If you are using LEDs, you must always operate them via a series re-
sistor. The series resistors are different depending on the rail power
and the characteristics of the LEDs. Determine the correct value for
the corresponding LED. You can connect several LEDs in parallel to
each output. In this case, each LED must have its own resistor. If you
connect several LEDs to one output in series, only one series resistor
is needed.
Connecting a backup capacitor
In track sections with bad contact the power supply of the decoder
can be interrupted briefly. At
solder pads ‘C –‘ and ‘C +’ a backup
capacitor (e.g. electrolytic capacitor 100 µF / 35V) can be soldered, in
order to improve power supply. Pay attention to the polarity of the
capacitor! The
positive pole is connected to ‘C +’, the negative pole to
‘C –‘.
Note: When using the decoder in analogue AC operation, the use of
a backup capacitor is recommended in any case.
Mounting/fastening the locomotive decoder
After completing of all connections to the decoder it should be
fastened. This can be done e.g. with double-sided tape. Please note
that the decoder heats up and the applied adhesive tape can possibly
be solved by heating. Take care that the decoder has no contact with
the conductive enclosure or chassis parts of the locomotive when
mounting.
