to each of the two parts. In order to supply the 8 LEDs of a whole PCB
(or the 7 LEDs of a shortened PCB), normally one capacitor or goldcap
is sufficient.
Choose an electrolytic capacitor or a goldcap with a capacity as high as
possible. As the housings of electrolytic capacitors and goldcaps are
bigger when the capacity is higher, the maximum capacity is limited by
the space available to mount the capacitor.
The minimum voltage sustaining capability of the goldcaps is 5,5 V. The
minimum voltage sustaining capability of the capacitor depends on the
power supply:
Power supply
Voltage sustaining capability of the bridging capacitor
< 18 V
> 16 V
> 18 V
> 25 V
Solder the external bridging capacitors according to fig. 5 to the
connecting points E(+) and E(-) and the goldcaps or further bridging
capacitors to the connecting points G(+) and G(-).
Connecting additional LEDs
You can connect up to 2 additional LEDs in series to each of the two
parts (e.g. for the train rear lighting). The necessary series resistors
are integrated on the PCB. Solder the LEDs according to fig. 6 to the
connecting points LED(-) and LED(+).
Please note: It is not possible to use electric bulbs instead of LEDs, as
the voltage is restricted so far by the integrated series resistors, that
the bulbs would not light.
Setting the switching on mode for the LEDs
You set the way the LEDs light when switched on, separately for each
of the two parts (with 4 LEDs each):
smooth brightening of the LEDs or
simulation of flickering fluorescent lamps.
The setting is done at the two soldering jumpers on the PCB (s. fig. 4).
In state of delivery (= soldering jumpers not bridged) the LEDs
brighten smoothly. In order to simulate flickering fluorescent lamps you
have to bridge the soldering jumper with a little tin-solder.
Setting the LEDs´ brightness
You can set the LEDs´ brightness via a trim-pot (see fig. 4) separately
for each of the two parts (with 4 LEDs each). This is also valid when
using the unparted whole PCB. For setting the trim-pot use a small
screw-driver.
Fixing the carriage lighting
After completing the connections, secure the lighting in place (eg. with
double sided adhesive tape).
