How to use this manual
If you have no specialist technical training, this manual gives step-by-
step instructions for safe and correct assembly of the kit or fitting of
ready-built modules, and operation. Before you start, we advise you to
read the whole manual, particularly the chapter on safety instructions
and the FAQ chapter. You will then know where to take care and how
to prevent mistakes which take a lot of effort to correct.
Keep this manual safely so that you can solve problems in the future. If
you pass the kit on to another person, please pass on the manual with
it.
Intended use
Caution:
Integrated circuits are very sensitive to static electricity. Do not touch
components without first discharging yourself. Touching a radiator or
other grounded metal part will discharge you.
The kit or the ready-built module can be assembled or fitted using this
manual. The ready-built module is designed for use in model railways.
It indicates the actual position of up to four solenoid accessories
(points, signals, etc.).
The kit and the ready-built module are not suitable for children under
the age of 14.
Reading, understanding and following the instructions in this manual
are mandatory for the user.
Any other use of the kit is inappropriate and invalidates any guarantees.

Safety instructions
Mechanical hazards
Cut wires can have sharp ends and can cause serious injuries. Watch
out for sharp edges when you pick up the PCB.
Visibly damaged parts can cause unpredictable danger. Do not use
damaged parts: recycle and replace them with new ones.
Electrical hazards
§Do not touch powered, live components.
§Do not touch conducting components which are live due to
malfunction.
§Avoid short circuits.
§Do not connect the circuit to a higher voltage than designed.
§Impermissibly high humidity.
§Condensation building up can cause serious injury due to electrical
shock.
Take the following precautions to prevent this danger:
§Never perform wiring on a powered module.
§Only use low power for this module as described in this manual and
only use certified transformers.
§Connect transformers and soldering stations only in approved mains
sockets installed by an authorised electrician.
§Observe cable diameter requirements.
§Assembling the kit should only be done in closed, clean, dry rooms.
Beware of humidity.
§If the humidity in the room is too high, please do not start working
until after a minimum of 2 hours of acclimatisation.
§Use only original spare parts if you have to repair the kit or the
ready-built module.

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.
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.

EMC declaration
This product is developed in accordance with the European standards
EN 55014 and EN 50082-1, tested corresponding to the EC - directive
89/336/EWG (EMVG of 09/11/1992, electromagnetic tolerance) and
meets legal requirements.
To guarantee the electromagnetic tolerance you must take the
following precautions:
§Connect the transformer only to an approved mains socket installed
by an authorised electrician.
§Make no changes to the original parts and accurately follow the
instructions, circuit diagram and PCB layout included with this
manual.
§Use only original spare parts if you have to repair the kit or the
ready-built module.
Operation overview
The module indicates the actual position of points (e.g. Märklin* M,
Märklin* K 15° to 1996) and signals with solenoid drive. Every indicator
can indicate the position of up to four points or signals. As the position
of the armature coil is analyzed, the module also reacts if points are
shifted manually. The evaluation ensues to ground so a digital check-
back-decoder (e.g. Märklin* S 88) can be connected directly. This
means old points can be integrated in a computer-assisted digital model
railway system.
Checking the package contents
Check the contents of the package for completeness:
§1 kit, containing the components listed in the parts list and 1 PCB or
§1 ready-built module
§1 manual.

Required tools and consumables
Make sure you have the following tools, equipment and materials ready
for use:
§a heat-resistant mat
§a soldering iron stand with tip-cleaning sponge
§a small side cutter and wire stripper
§a pair of tweezers and long nose pliers (not necessary for the
ready-built module)
§an electronic soldering iron (max. 30 Watt) with a fine tip

Safe and correct soldering
Caution:
Incorrect soldering can cause fires (through excessive heat). Avoid this
danger 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 SN 60 Pb (i.e. 60 % tin, 40 % lead) with rosin-
based flux.
§Solder fast: long soldering can destroy components and copper
tracks, and damages through plated holes.
§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.
§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 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. A
glossy and perfect soldering spot should remain.
§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.
English
Page 26
§Cut the wires after soldering directly above the PCB solder side with
a side cutter.
§After placing the parts, please double check for correct polarity.
Check the PCB tracks for solder bridges, 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 a ready-built module.
Preparation
Put the sorted components in front of you on your workbench. An
explanation of the separate electronic components follows:
Resistors
A resistor will "brake" the current. Mounting orientation is of
no importance. Because resistors are very small there is no
readable information on them, but their value is given with
colour rings.
Key:
Value Colour ring
4,7 kΩyellow - violet - red (gold)
10 kΩbrown - black - orange (gold)
47 kΩyellow - violet - orange (gold)
470 kΩyellow - violet - yellow (gold)
The colour ring in brackets indicates the tolerance of the
resistor and is of no importance here.
Capacitors
There is a difference between “normal” capacitors and
electrolytic capacitors which have to be placed in a certain
direction. They have a very bright line at one end marked with
