6.2. Connection to the power
supply
Solder the connecting wires for the
power supply to the connecting points
P1, P3 or P5 (from the left rail) and the
connecting points P2, P4 or P6 (from
the right rail).
You can loop through the power supply
from one PCB to the next and thus
supply several carriage lighting from
one current source.
Caution:
When using power transmissing
couplings pay attention not to exceed
the maximum current of the couplings!
6.3. Connecting bridging capacitors
In order to bridge currentless sections you can connect external
bridging capacitors to the PCB (section 1).
For the supply of
the LEDs: an electrolytic capacitor with a voltage sustaining
capability of > 16 V or two goldcaps with a voltage sustaining
capability of > 5,5 V. Solder them to the connecting points E1(+)
and E1(-).
Loads connected to the outputs of the integrated function decoder:
an electrolytic capacitor with a voltage sustaining capability of
> 25 V or, when connecting it to analogue a.c. voltage, > 35 V.
Solder it to the connecting points E2(+) and E2(-).
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.
6.4. Connecting a light depending
resistor
You can switch on and off the LEDs and the
decoder´s function outputs automatically
depending on the surrounding lighting when
mounting a light depending resistor to the
connecting points LDR1 and LDR2.
