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.
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.
Follow the connecting diagram fig. 9. 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).
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.
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.
Connecting PCB section 2
You can use section 2 of the PCB you have sawed off as a LED PCB.
Either connect it according to fig. 10 to the output of a locomotive or
function decoder (e.g. the integrated function decoder of section 1) and
switch the LEDs digitally or connect it according to fig. 11 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 (see fig. 11).
Setting the LEDs´ brightness
Instead of programming with a digital control unit you can set the LEDs´
brightness via a trim-pot (see fig. 5). For setting the trim-pot use a
small screw-driver.
The brightness programmed via CVs or register remains active, the
settings at the trim-pot only alter the brightness with a factor valid for
all LEDs.
Fixing the carriage lighting
After completing the connections, secure the lighting in place (eg. with
double sided adhesive tape).
