SD-34 | SD-34.2 English 1. Getting started How to use this manual ni k This manual gives step-by-step instructions for safe and correct assembly of the kit and fitting and connecting 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 checklist for trouble shooting. You will then know where to take care and how to prevent mistakes which take a lot of effort to correct.
English SD-34 | SD-34.2 Checking the package contents For assembling the kit you need: an electronic soldering iron (max. 30 Watt) or a regulated soldering iron with a fine tip and a soldering iron stand, a tip-cleaning sponge, a heat-resistant mat, a small side cutter and wire stripper, as necessary a pair of tweezers and long nose pliers, electronic tin solder (0,5 mm. diameter).
SD-34 | SD-34.2 English 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. Electrical hazards ni k Visibly damaged parts can cause unpredictable danger. Do not use damaged parts: recycle and replace them with new ones. el ek ta m Never perform wiring on a powered module. Assembling and mounting the kit should only be done in closed, clean, dry rooms. Beware of humidity.
English SD-34 | SD-34.2 Fire risk ni Thermal danger k 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.
SD-34 | SD-34.2 English 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. ! k 3. Safe and correct soldering Caution: ta m el ek 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.
English 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 soldering joint with a side cutter. 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.
SD-34 | SD-34.2 English 4. Operation overview lightings, light signals, motor-run points with tape shut-off. ni k The switching decoders SD-34 and SD-34.2 are designed to control accessories, switched on and off or changed over via a change-over relay, e.g. tro With one switching decoder you can control a maximum of four accessories independent of each other. Driving the decoder via accessory decoder commands el ek The outputs of the decoders SD-34 and SD-34.
English SD-34 | SD-34.2 Programming Using a DCC central unit the decoder address and 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 (SD-34) or a push-button switch (SD-34.2). Feedback via RailCom tro ni k When using a Motorola central unit the (accessory) decoder address has to be set with a programming jumper (SD-34) or a push-button switch (SD-34.2).

English SD-34 | SD-34.2 6. Assembling the kit (SD-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. ni k The separate electronic components have the following special features you should take into account in assembling: Resistors el ek tro Resistors reduce current. The value of resistors for smaller power ratings is indicated through colour rings. Every colour stands for another figure.
SD-34 | SD-34.2 English Ceramic capacitors k Among other things ceramic capacitors are used for filtering interference voltages or as frequency determining parts. Ceramic 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 100 nF. ni Electrolytic capacitors el ek tro Electrolytic capacitors are often used to store energy. In contrast to ceramic capacitors they are polarized.
English SD-34 | SD-34.2 Light emitting diodes (LEDs) k 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. ni Transistors tro Transistors are current amplifiers which convert low signals into stronger ones.
SD-34 | SD-34.2 English Opto couplers Opto couplers are ICs, 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. k Relays tro ni Relays are electronic switches, depending on their position the one or other (internal) connection is closed.

Follow the instructions on soldering in section 3. tro ni k ! Caution: Several components have to be mounted according to their polarity. When soldering these components the wrong way round, they can be damaged when you connect the power. In the worst case the whole circuit can be damaged.
SD-34 | SD-34.2 English Resistor R4 Solder the resistor that way, it´s body is standing upright on the PCB. 9. Relays The mounting orientation is given by the layout of the pins. 10. Electrolytic capacitors Observe the polarity! One of the two leads (the shorter one) is marked with a minus sign. 11. Terminal strips Put together the terminal strips before mounting them. 12. ICs in DILhousing Insert the ICs into the soldered socket.
English SD-34 | SD-34.2 7. Connecting the decoder The decoder has terminal strips inserted to plug in and screw on the connecting wires.

SD-34 | SD-34.2 English With Motorola central units the address can be set via the programming jumper (SD-34) or the programming push-button (SD-34.2) only. When using DCC central units it is often easier to set the address via the programming jumper / push-button than to program it via CV. k Hint: Setting the address via the jumper / push-button is impossible unless the decoder is operated by points addresses.
