1. Getting started

How to use this manual

This manual gives step-by-step instructions for safe and correct assembly of the kit and fitting of the ready-built module, 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 or the ready-built module on to another person, please pass on the manual with it.

Intended use

The kit or the ready-built module can be assembled and operated with a digital model railway run in DCC or Motorola format to operate solenoid accessories (point decoder WD-34) or other accessories (accessory decoder SD-34), using this manual.

Any other use is inappropriate and invalidates any guarantees. The kit and the ready-built module should not be assembled or fitted by

children under the age of 14. Reading, understanding and following the instructions in this manual

are mandatory for the user.

Caution:

The circuit contains integrated circuits. These 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.

SD-34 / WD-34 English

Checking the package contents

Please make sure that your package contains:

§ one kit, containing the components listed in the parts and one PCB

or one ready-built module,

§ one jumper for programming the address,

§ one manual.

Required materials

For assembling the kit you need:

§ an electronic soldering iron (max. 30 Watt) with a fine tip,

§ a soldering iron stand,

§ a tip-cleaning sponge,

§ a heat-resistant mat,

§ a small side cutter and wire stripper,

§ a pair of tweezers and long nose pliers,

§ tin solder (0,5 mm. diameter),

In order to connect the module you need wire. Recommended diameters: > 0,25 mm² for all connections.

2. 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

§ Touching powered, live components,

§ touching conducting components which are live due to malfunction,

§ short circuits,

§ connecting the circuit to another voltage than specified,

Page 29

English SD-34 / WD-34

§ impermissibly high humidity,

§ condensation build up

can cause serious injury due to electrical shock. Take the following precautions to prevent this danger:

§ Never perform wiring on a powered module.

§ Assembling and mounting the kit should only be done in closed,

clean, dry rooms. Beware of humidity.

§ Only use low power for this module as described in this manual and

only use certified transformers.

§ Connect transformers and soldering irons only in approved mains

sockets installed by an authorised electrician.

§ Observe cable diameter requirements.

§ After condensation build up, allow a minimum of 2 hours for dispersion.

§ 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 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.

SD-34 / WD-34 English

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, 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. 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 32

SD-34 / WD-34 English

§ 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.

4. Operation overview

Driving the decoder

The decoder´s outputs are operated via accessory decoder commands in DCC or Motorola format, sent from the central unit to one of the four accessory decoder´s addresses. The decoder automatically recognizes the commands´data format. It is possible to switch the outputs via mixed DCC and Motorola commands as well as to operate one output alternately in DCC and Motorola format.

Use

The point decoder WD-34 activates up to four connected points or up to eight other solenoid accessories. Application areas are coil driven points, semaphore type signals and decouplers.

The accessory decoder SD-34 has four integrated change-over relays to operate connected accessories. Application areas are lightings of all kind, light signals and motor-run points with tape shut-off.

Programming

Using a DCC central unit the decoder´s features can be defined by programming the configuration variables (CV). It is also possible to set the address by using a programming jumper.

When using a Motorola central unit the decoder address has to be set with a programming jumper. Changing the other decoder´s features is neither necessary nor possible in layouts run in Motorola format only.

Feedback

The SD-34 and the WD-34 are RailCom compatible, i.e. the decoders are able to pass the RailCom messages via the rails to special RailCom detectors. This allows e.g. to feedback the correct performance of setting and switching commands or the actual setting of points.

Power supply

The decoder 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 decoder by a transformer of it´s own.
