Fire risk
Touching flammable material with a hot soldering iron can cause fire,
which can result in injury or death through burns or suffocation.
onnect your soldering iron or soldering station only when actually
needed. Always keep the soldering iron away from inflammable
materials. Use a suitable soldering iron stand. 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 from the
soldering tip.
angerous 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
hildren can cause any of the accidents mentioned above because they
are inattentive and not responsible enough. hildren under the age of
14 should not be allowed to work with this kit or the ready-built
module.
Caution:
Little children can swallow small components with sharp edges, with
fatal results! Do not allow components to reach small children.

In schools, training centres, clubs and workshops, assembly must be
supervised by qualified personnel.
In industrial institutions, health and safety regulations applying to
electronic work must be adhered to.
3. Safe and correct soldering
Caution:
Incorrect soldering can cause dangers through fires and heat. Avoid
these dangers by reading and following the directions given in the
chapter Safety instructions.
Use a small soldering iron with max. 30 Watt or a regulated
soldering iron.
Only use electronic tin solder with flux.
When soldering electronic circuits never use soldering-water or
soldering grease. They contain acids that can corrode components
and copper tracks.
Insert the component connecting pins of into the P B´s holes as far
as possible without force. The components should be close to the
P B´s surface.
Observe correct polarity orientation of the parts before soldering.
Solder quickly: holding the iron on the joints longer than necessary
can destroy components and can damage copper tracks or soldering
eyes.
Apply the soldering tip to the soldering spot in such a way that the
part and the soldering eye 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 solder flows into the joint, 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. lean the soldering tip with a damp piece of cloth, a
damp sponge or a piece of silicon cloth.
ut the wires after soldering directly above the soldering joint with a
side cutter.
After placing the parts, please double check for correct polarity.
heck the P B tracks for solder bridges and short circuits created by
accident. This would cause faulty operation or, in the worst case,
damage. You can remove excess solder by putting a clean soldering
tip on the spot. The solder will become liquid again and flow from
the soldering spot to the soldering tip.

4. Operation overview
The turnout decoders WD-34, WD-34.2 and WD-34.M are designed to
control accessories, activated by a short switching impulse. So, it is
possible to switch as well accessories with as without tape shut-off.
Examples of use:
WD-34 WD-34.2 WD-34.M
oil driven turnouts X X X
Semaphore signals
with twin coil drive X X X
Decouplers X X X
Motor driven turnouts AMW-2
required
AMW-1
required X
With one turnout decoder you can control a maximum of:
four turnouts or semaphores with twin coil drive or
eight other solenoid accessories or
four motor driven points.
It is possible to connect a different types of accessories to the four
pairs of outputs.
riving the decoder via accessory decoder commands
The outputs of the decoders are operated via accessory decoder
commands in D or Motorola format, sent from the central unit to one
of the four accessory decoder´s addresses. The decoders automatically
recognize the commands´data format. It is possible to switch the
outputs via mixed D and Motorola commands as well as to operate
one output alternately in D and Motorola format.

WD-34 | WD-34.2 | WD-34.M English
Operation via vehicle decoder commands
(W -34.2 and W -34.M only)
You can use a vehicle decoder address (locomotive address) to operate
the turnout decoders WD-34.2 and WD-34.M instead of an accessory
decoder address (turnout address). The 4 outputs of the decoder are
switched via the function keys F1 to F4 then. This allows to use the
WD-34.2 and WD-34.M in combination with D control units not
designed for controlling turnout addresses.
Programming
Using a D central unit, the decoder address and the decoder´s
features can be defined by programming the configuration variables
( V). It is also possible to set the address by using a programming
jumper (WD-34) or a push-button switch (WD-34.2 and WD-34.M).
When using a Motorola central unit the (accessory) decoder address
has to be set with a programming jumper (WD-34) or a push-button
switch (WD-34.2 and WD-34.M). hanging the other decoder´s
features or assigning a locomotive address is neither necessary nor
possible in layouts run in Motorola format only.
Feedback via RailCom
The turnout decoders are Rail om compatible, i.e. the decoders are
able to pass the Rail om messages via the rails to special Rail om
detectors. This allows e.g. to feedback the correct performance of
setting and switching commands or the actual setting of turnouts.
Page 11

tams elektronik
English WD-34 | WD-34.2 | WD-34.M
Feedback of a wrong position of turnouts (W -34.2 only)
After the set switching time ("on-time"), the turnout decoder WD-34.2
compares the actual position of turnouts with limit stop with the
position it should have according to the digital commands. If the
position does not match, e.g. because
a mechanical problem has occurred or
the turnout has been switched manually
the fault can be displayed at an external LED (LED not included in the
package). The flashing sequence shows the turnout in question.
Short-circuit protection
In case a short-circuit occurs while switching a connected accessory,
the decoder stops the switching operation and the LED on the P B
starts to flash quickly.
Power supply
The turnout decoders can either be supplied by the central unit or a
booster. In order to release the digital electric circuit it is also possible
to supply the decoders by a transformer of their own instead.

6. Assembling the kit (WD-34)
You can skip this part if you have purchased a ready-built module or device.
Preparation
Put the sorted components in front of you on your workbench.
The separate electronic components have the following special features
you should take into account in assembling:
Resistors
Resistors reduce current.
The value of resistors for smaller power ratings is indicated
through colour rings. Every colour stands for another
figure.
arbon film resistors and some types of wire resistors have
4 colour rings. The 4th ring (given in brackets here)
indicates the tolerance of the resistor (gold = 5 %).
Value: olour rings:
0,27 red - violet - silver (gold)
33 orange – orange – black (gold)
100 brown - black - brown (gold)
220 red - red - brown (gold)
1 kbrown - black - red (gold)
1,5 k brown - green - red (gold)
2,2 k red - red - red (gold)
4,7 kyellow - violet - red (gold)
10 kbrown - black - orange (gold)

Ceramic capacitors
Among other things ceramic capacitors are used for
filtering interference voltages or as frequency determining
parts. eramic capacitors are not polarized.
Normally they are marked with a three-digit number which
indicates the value coded. The number 104 corresponds to
the value 104.
Electrolytic capacitors
Electrolytic capacitors are often used to store energy. In
contrast to ceramic capacitors they are polarized. The
value is given on the casing.
Electrolytic capacitors are available with different voltage
sustaining capabilities. Using an electrolytic capacitor with
a voltage sustaining capability higher than required is
always possible.
iodes and Zener diodes
Diodes allow the current to pass through in one direction
only (forward direction), simultaneously the voltage is
reduced by 0,3 to 0,8 V. Exceeding of the limit voltage
always will destroy the diode, and allow current to flow in
the reverse direction.
Zener diodes are used for limiting voltages. In contrast to "normal"
diodes they are not destroyed when the limit voltage is exceeded.
The diode type is printed on the body.
Page 15

tams elektronik
English WD-34 | WD-34.2 | WD-34.M
Light emitting diodes (LE s)
When operated in the forward direction the LEDs light.
They are available in several different versions (differing in
colour, size, form, luminosity, maximum current, voltage
limits).
Light emitting diodes should always be connected via a
series resistor which limits the current and prevents failure.
Transistors
Transistors are current amplifiers which convert low signals
into stronger ones. There are several types in different
package forms available. The type designation is printed
on the component.
Transistors for a low power rating (e.g. B types) have a
package in form of a half zylinder (SOT-Gehäuse).
Transistors for a high power rating (e.g. BD types) have a
flat package (TO-package), which is in use in different
versions and sizes.
The three pins of bipolar transistors (e.g. B and BD
types) are called basis, emitter and collector (abbreviated
with the letters B, E, in the circuit diagram).
Integrated circuits (ICs)
Depending on the type, I s fulfil various tasks. The most
common housing form is the so-called "DIL"-housing, from
which 4, 6, 8, 14, 16, 18 or more "legs" (pins) are
arranged along the long sides.
I s are sensitive to damage during soldering (heat,
electrostatic charging). For that reason in the place of the
I s I sockets are soldered in, in which the I s are
inserted later.
Page 16

tams elektronik
WD-34 | WD-34.2 | WD-34.M English
Microcontrollers
Microcontrollers are I s, which are individually programmed for the
particular application. The programmed controller are only available
from the manufacturer of the circuit belonging to it.
Opto couplers
Opto couplers are I s, which work similar to laser beam switches. They
combine in one housing a light emitting diode and a photo transistor. Their
task is the transmission of information without galvanic connection. They
are in a DIL-housing with at least 4 pins.
Terminal strips
Terminal strips are solder-in screw-type terminals. They provide a
solder-free and safe connection of the cables to the circuit, which can
still be separated any time.
