Fire risk
Touching flammable material with a hot soldering iron can cause life-
threatening fire, burns and toxic smoke. Connect your soldering iron or
soldering station only when actually needed. Use the correct soldering
iron or station and never leave a hot soldering iron or station
unattended.
Thermal danger
A hot soldering iron or liquid solder accidentally touching your skin can
cause skin burns. As a precaution:
§use a heat-resistant mat during soldering,
§always put the hot soldering iron in the soldering iron stand,
§point the soldering iron tip carefully when soldering, and
§remove liquid solder with a thick wet rag or wet sponge.
Dangerous environments
A working area that is too small or cramped is unsuitable and can cause
accidents, fires and injury. Prevent this by working in a clean, dry room
with enough freedom of movement.
Other dangers
Children can cause any of the accidents mentioned above because they
are inattentive and not responsible enough. Children under the age of
14 should not be allowed to work with this kit or the ready-built
module.
Little children can swallow small components with sharp edges. Life
threatening! Do not allow components to reach small children.

Information: Speed mode
Digital control units for DCC format can send 14, 28 or 128 speed levels
depending on the model and the settings. The number of speed levels sent
by the control unit (=speed mode) must be set at the decoder as well.
The speed mode set at the digital control unit for a particular decoder
address must correspond to the speed mode saved in the function
decoder. Otherwise the performance of the decoder may be incorrect.
Information: Configuration variables (CVs)
You can set the so-called configuration variables of the decoder from
the control unit. The programming of the variables allows the
adjustment of the decoder to the individual needs of the user.
The configuration variables are saved in the decoder and are also
preserved if the decoder is switched off. Changing the configuration
variables is possible at any time from the digital control unit.
The configuration variables for the DCC format are standarised. The
variables that can be set depend on the decoder type.

English FD-5
Page 22
Operation overview
The decoder is designed for operation in DCC format and can be
adjusted to one of 127 basic addresses or to one of 10.239 extended
addresses. It switches the accessories connected to the seven outputs
via the functions F0 to F4. Other functions are not available with the
FD-5.
The configuration variables of the FD-5
The following configuration variables (CVs) can be set from the digital
control unit:
§Basic address (CV 1)
§Version (CV#7) – read only
§Manufacturer identification (CV#8) - read only
§Extended address (CV#17 und CV#18)*
§Consist-Address (CV 19)*
§Configuration data (CV 29)
§Utilisation and setting of output X9 and X10 (CV 56)*
*Not possible with central units with register programming!
Function F0 (Light)
The lights can be switched from the digital control unit. You can either set
the lighting according to the direction of travel or a fixed light for both
directions of travel by programming the configuration variable CV 56.
Functions F1 and F3
Each of the functions F1 and F3 allow two accessories connected to the
outputs X4 and X5 resp. X7 and X8, with a max. current consumption of
500 mA, to be switched on or off. Parallel switching of the outputs is also
possible. In this way accessories with a maximum current consumption of
up to 900 mA can be switched. They are available for optional accessories
(e.g. smoke generator, cab lighting, sound module).

FD-5 English
Page 23
Function F2
The function F2 allows an accessory connected to the output X6, with a
maximum current consumption of 500 mA, to be switched on or off.
Function F4
If the configuration variable CV 56 is programmed accordingly, the
function F4 allows an optional accessory, connected to the output X9,
to be switched on or off. If lighting for reverse direction is programmed
for the output X9, the function F4 has no effect on this output.

Safe and correct soldering
Caution:
Incorrect soldering can cause fires (through excessive heat). Avoid this
dager by reading the chapter Safety instructions again and following
the directions given.
If you have had training in soldering you can skip this chapter.
§When soldering electronic circuits never use soldering-water or
soldering grease. They contain acids that can corrode components
and copper tracks.
§Only use tin solder with flux.
§Use a small soldering iron with max. 30 Watt. Keep the soldering tip
clean so the heat of the soldering iron is applied to the solder point
effectively.
§Solder fast: long soldering can destroy components and copper
tracks, and damages through plated holes.
§Apply the soldering tip to the soldering spot in such a way that the part
and the soldering spot are heated at the same time. Simultaneously
add solder (not too much). As soon as the solder becomes liquid take it
away. Hold the soldering tip at the spot for a few seconds so that the
tin solder finds its way, then remove the soldering iron.
§Do not move the component for about 5 seconds after soldering.
§To make a good soldering joint you must use a clean and
unoxidised soldering tip. Clean the soldering tip with a damp piece
of cloth, a damp sponge or a piece of silicon cloth.
Performing a visual check
Damaged materials can cause injury. Parts damaged during transit can
also be dangerous. Check the module for damage, missing parts or
poor soldering. If you find damage, return the module for exchange.

Mounting the function decoder
Open the locomotive or the carriage housing. Locate the position for
the decoder.
Follow the connections diagrams (fig. 1a and 1b)! Solder the
connections to the rails at points X2 and X3.
Connecting the lighting and other accessories
Follow the connections diagrams (fig. 1a and 1b)!
Disconnect any existing diodes in the leads to the lamps. Connect the
lamps for forward motion to X10 and - if desired - the lamps for reverse
motion to point X9. If the lamps are already connected with one side to
ground, you must solder in a diode between the decoder and the lamp
(see fig. 1a) Otherwise you must connect the second side of the lamps
according to fig. 1b to the return conductor (point X1).
Connect other accessories (e.g. smoke generator, noise module), which
are switched by the functions F1 to F4, to the points X4 to X8. Connect
the accessory which is switched via the function F2 to the point X6. The
accessories connected to the points X4 and X5 resp. the points X7 and
X8 are switched jointly on and off via the functions F1 resp. F3. If you
want to connect an accessory with a current consumption of more than
500 mA you must connect the two outputs in parallel (fig. 1a and 1 b,
connection to X4 and X5). You can connect a further accessory to point
X9 which can be switched via the function F4 instead of the lighting for
reverse direction.
Caution:
The current consumption of all connected accessories may not exceed
1.500 mA!
You can connect the second side of the accessories either to the return
conductor (point X1) or to ground. If connecting the accessory to
ground you must solder in a diode.

Caution:
The return conductor for all functions (point X1) must under no
circumstances be connected to locomotive resp. carriage ground.
Possible short circuit! The decoder will be damaged in operation.
Caution:
If you connect the loads to the return conductor for all functions (point
X1), the loads must be insulated. The loads must not make contact with
metal parts of the locomotive or the carriage. Possible short circuit! The
decoder will be damaged in operation.
Connecting the LEDs
The function outputs of the decoder switch against decoder ground. For
that reason you must connect the cathode (-) of the LED to the output
of the relevant function.
Caution:
If you use light-emitting diodes (LEDs) you must always operate them
via a series resistor.
LEDs are available in many different models. There are LEDs with 2-5
mA, but also LEDs with 15-30 mA power consumption. The series
resistor limits the current flow of the LED and will need to be calculated
for each model. Ask for the max current rating when buying your LEDs.
You can connect several LEDs in parallel to each output. In this case every
LED must have a series resistor of its own. If you connect several LEDs to
one output in series, only one series resistor is needed. The number of
LEDs connected in series to one output depends on the digital voltage.
You can determine the number of the LEDs that can be connected in
series to one output from the following formula:
(number of LEDs + 2) x 1,5 < digital voltage
Fixing the decoder
After completing all connections fix the decoder with double-sided
adhesive tape, for example.
