Fire risk
Touching flamma le material with a hot soldering iron can cause fire,
which can result in injury or death through urns or suffocation.
Connect your soldering iron or soldering station only when actually
needed. Always keep the soldering iron away from inflamma le
materials. Use a suita le 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 urns. 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.
Dangerous en ironments
A working area that is too small or cramped is unsuita le and can cause
accidents, fires and injury. Prevent this y working in a clean, dry room
with enough freedom of movement.
Other dangers
Children can cause any of the accidents mentioned a ove ecause they
are inattentive and not responsi le enough. Children under the age of
14 should not e allowed to work with this kit or the ready- uilt

In schools, training centres, clu s and workshops, assem ly must e
supervised y qualified personnel.
In industrial institutions, health and safety regulations applying to
electronic work must e adhered to.
3. Safe and correct soldering
Caution:
Incorrect soldering can cause dangers through fires and heat. Avoid
these dangers y 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 into the PCB´s holes as far as
possi le without force. The components should e close to the
PCB`s surface.
O serve correct polarity orientation of the parts efore 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
ecomes 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.
Page 7

English SV-2
Do not move the component for a out 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.
Cut the wires after soldering directly a ove the soldering joint with a
side cutter.
After placing the parts, please dou le check for correct polarity.
Check the PCB tracks for solder ridges and short circuits created y
accident. This would cause faulty operation or, in the worst case,
damage. You can remove excess solder y putting a clean soldering
tip on the spot. The solder will ecome liquid again and flow from
the soldering spot to the soldering tip.

4. Operation overview
The switching amplifier provides the energy to switch points with
dou le solenoids. Applications:
Switching stiff points. It is possi le to switch stiff points independent
of the power of the transformer.
Simultaneously switching several points. Each of them has to e
connected to a switching amplifier of its own and then all points can
e switched simultaneously via one impulse.
The switching amplifier works, drastically simplified, like a flash gun.
The electric charge which is necessary to switch points is stored in an
electrolytic capacitor.
The switching operation is activated via a transistor, y connecting one
of the inputs shortly with earth. To make the earth contact, a push
utton, a control panel, a circuit track or similar can e used. Turnout
decoders are not suita le to activate the switching operation.

6. Assem ling the kit
You can skip this part if you have purchased a ready- uilt module or device.
Preparation
Put the sorted components in front of you on your work ench.
The separate electronic components have the following special features
you should take into account in assem ling:
Resistors
Resistors reduce current. Their mounting orientation is of
no importance. The value of resistors for smaller power
ratings ( eneath 0,5 W) is indicated through colour rings.
Every colour stands for another figure. The colour ring in
rackets indicates the tolerance of the resistor which here
is of no importance.
Value: Colour ring:
120 rown - red - rown (gold)
1 krown - lack - red (gold)
Diodes
Diodes allow the current to pass through in one direction
only (forward direction), simultaneously the voltage is
reduced y 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.
The diode type is printed on the ody. Diodes must e mounted in a
given direction. The negative end is marked with a ring. This is shown
in the PCB layout.
Page 10

SV-2 English
Electrolytic capacitors
Electrolytic capacitors are often used to store energy. In
contrast to ceramic capacitors they are polarized. One of
the two leads is marked with a minus sign which indicates
the mounting orientation. The value is given on the casing.
Electrolytic capacitors are availa le with different voltage sustaining
capa ilities. Using an electrolytic capacitor with a voltage sustaining
capa ility higher than required is always possi le.
Transistors
Transistors are current amplifiers which convert low signals into
stronger ones. They have three contacts. As they are polarized, they
have to e mounted in a certain direction.
The BD-types have a flat housing (TO-housing) with the
type designation printed on the front side. The metallic
rear is unla elled, on the PCB layout the rear is marked y
a thick line.
PCB sockets
The widely spread 2,6 mm model railway connectors fit exactly to the
sockets. These are used for the connection to the voltage supply and to
connected modules or components.

Caution:
Several components have to e mounted according to their polarity.
When soldering these components the wrong way round, they can e
damaged when you connect the power. In the worst case the whole
circuit can e damaged. At the est, a wrongly connected part will not
function.
1. Resistors Mounting orientation of no importance.
2. Diodes O serve the polarity!
The negative end of the diodes is marked with
a ring. This is shown in the PCB layout.
3. PCB sockets
4. Transistors O serve the polarity!
With transistors for a high power rating in TO
packages (e.g. BD types) the unla elled ack
side is marked in the PCB layout y a thick
line.
5. Electrolytic
capacitors
O serve the polarity! One of the two leads
(the shorter one) is marked with a minus sign.
Performing a isual check
Perform a visual check after the assem ly of the module and remove
faults if necessary:
Remove all loose parts, wire ends or drops of solder from the PCB.
Remove all sharp wire ends.
Check that solder contacts which are close to each other are not
unintentionally connected to each other. Risk of short circuit!
Check that all components are polarised correctly.
When you have remedied all faults, go on to the next part.

Connections 1
Testing the switching amplifier
Connect temporally the sockets "GND" and "S1" with one another. The
points should switch now. If the points do not switch they are possi ly
in the corresponding position. Switch the points y hand in the other
position and try to switch the points again. Then connect "GND" to
"S2". The points should switch again. Please note: You have to wait for
a moment (approx. 2 sec.) etween the two switching operations in
order to get the capacitor reloaded.
Caution: If a component gets too hot, disconnect the module
and power supply from the mains immediately. Possi le short circuit!
Check the assem ly.
After a successful function test, disconnect the switching amplifier from
the power supply. Mount the module as desired in your model railroad
layout.
