Fire risk
Touching flammable material with a hot soldering iron can cause fire,
which can result in injury or death through burns or suffocation.
Connect 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.
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.

Operation overview
The light signal switch is developed to control a Maerklin* Hobby-light
signal. Using it with Viessmann*-signal kits is possible as well. The
Viessmann*-signal kits have to be modified, you can order the manual
from us or you can download it from our homepage.
The light signal switch has to be connected between the light signal and
an external change-over switch which switches between the two signals
("red" and "green"). Using a switching decoder to switch between the
two signals is possible as well. Push-button switches as used e.g. to
switch points are not suitabe to switch between signals. In exactly the
same way as in real life, the light signal switch causes the LED switched
off to fade slowly and the LED switched on to brighten slowly.

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. If you have had training in soldering you
can skip this chapter.
§ 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.
§ 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.
§ Solder quickly: holding the iron on the joints longer than necessary
can destroy components and can damage copper tracks or
soldering eyes.
§ Observe correct polarity orientation of semi-conductors, LEDs
electrolytic capacitors and integrated circuits before soldering and
ensure that the solder time does not exceed 5 seconds, otherwise
components can be damaged.
§ 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. 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 above the PCB solder side with
a side cutter.
Page 27
English LSU
§ After placing the parts, please double check for correct polarity.
Check the PCB 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.
Assembling the kit
You can skip this part if you have purchased a ready-built module.
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 to prevent mistakes in assembling:
Resistors
Resistors reduce current. Their mounting orientation is of no
importance. The value of resistors for smaller power ratings
(under 5 W) is indicated through colour rings. Every colour
stands for another figure. The colour ring in brackets indicates
the tolerance of the resistor which here is of no importance.
Value Colour rings
100 Ω brown - black - brown (gold)
4,7 kΩ yellow - violet - red (gold)
22 kΩ red - red - orange (gold)
Page 28
LSU 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 available with different voltage
sustaining capabilities. Using an electrolytic capacitor with a
voltage sustaining capability higher than required is always
possible.
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.
The diode type is printed on the body.
Diodes must be mounted in a given direction. The negative
end is marked with a ring. This is shown in the PCB layout.
Transistors
Transistors are current amplifiers which convert low signals
into stronger ones. They have three contacts. As they are
polarized, they have to be mounted in a certain direction.
BC-Types have a housing in form of a half cylinder (SOThousing). The cross section is shown in the PCB Layout which
determines the mounting orientation.
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 seperated any time. When several terminal strips have to be
mounted side by side, they have to be put together before mounting.

Assembling the kit
Start the assembly with the resistors and the diodes. First solder the
components on the solder side of the PCB and then cut the excess
wires with the side cutters, as short as possible. Continue the assembly
with the electrolytic capacitors and the transistors.
Caution:
Diodes, electrolytic capacitors and transistors must be placed in the
right direction! If you solder them the wrong way the affected parts can
be damaged when you connect the power. In the worst case the whole
circuit can be damaged. At the best, a wrongly connected part will not
function.
Finally solder the terminal strips. Join them together before soldering.
Performing a visual check
Perform a visual check after the assembly 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.
Connecting the light signal switch
The Maerklin* Hobby-light signals have two blue and one red
connecting wire with a connector. Break off the connector, you won’t
need it. In case you want to install an additional train synchronisation
you can use the red wire again.
Then make the connections according to the following list and the
connecting diagram (Fig. 3).

TRANSFORMER
Fig. 3: Connecting the signal
Page 32
LSU English
After having connected the transformer to the power supply the LED
should light. As soon as you operate the change-over switch the LED
should fade slowly and the second LED should brighten slowly.
In case the LEDs do not light as described please check the module
with help of the chapter "FAQ".
Connecting the train synchronisation
It is possible to synronise a train with the signal. For that purpose you
need a bipolar change-over switch instead of a simple switch. Divide
the rail section for the train´s halt, from the rest of the rails as
described in the signal´s manual.
Follow the connecting diagram fig. 4. Connect the change-over switch
as follows:
Middle connecting point: Middle conductor of the rail section behind the
signal (in direction of travel).
Connecting point closed with a green signal: Middle conductor of the
divided rail section in front of the signal.
Switch "b" of the
bipolar change-over switch /
position "green signal"
