6.5. Connecting LEDs to the output AUX2
The output AUX2 has been designed for the
connection of LEDs for the back lighting. The
maximum current is 20 mA. The necessary series
resistors are integrated on the PCB. Solder the
LEDs to the connecting points AUX2 and RL2.
Caution:
!
Do not connect electric bulbs to the output AUX2!
These have normally a current of more than 20
mA. The output will be damaged when setting-up
operation.
6.6. Connecting auxiliary devices to the
outputs AUX1 and AUX3
Before connecting additional lighting, couplings or
other auxiliary devices to the outputs AUX1 and
AUX3, check if their current is below the maximum
permissible value of 300 mA. If connecting devices
with a higher current to the PCB, the output will be
damaged in the setting-up operation.
Disconnect any existing diodes in the leads to the
lamps. If the lamp or the accessory is already
connected to vehicle ground, you have to connect it
to the output only. If not, connect the second side
of the accessory to the return conductor of the
decoder (point RL1).
Caution:
!
If you connect the accessories to the return conductor for all functions
(point RL1), the accessories must be insulated. The accessories should
not make contact with metal parts of the vehicle. Possible short circuit!
The module will be damaged in operation.
Caution:
!
The return conductor for all functions (point RL1) must under no
circumstances be connected to vehicle ground. Possible short circuit!
The module will be damaged in operation.
6.7. Connecting PCB section 2
You can use section 2
of the PCB you have
sawed off as a LED
PCB. Either connect it
to the output of a
locomotive or function
decoder
(e.g.
integrated
decoder of section 1)
and switch the LEDs
digitally or connect it
directly to an analogue
power supply.
The five connecting points L4 to L8 are assigned to the LEDs 4 to 8 on
the PCB. When connecting the connecting points separately to the
outputs of a decoder you can activate each of the LEDs separately in
digital operation.
Connect the connecting point RL3 to the return conductor of the
decoder or to the analogue power supply. When using the PCB in
analogue layouts you have to mount a rectifier.
