S88-3 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 S88-3 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).
S88-3 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. ni Electrical hazards k Visibly damaged parts can cause unpredictable danger. Do not use damaged parts: recycle and replace them with new ones. ta m el ek 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 S88-3 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.
S88-3 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. 3. Safe and correct soldering 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.
S88-3 English 4. Operation overview ni k The feedback module S88-3 is compatible with all components working with the s88-bus developed by the company Märklin**. It can read in 16 mass contacts. This information is transferred via the s88-bus to the upstream module or to the connected digital unit (interface, memory or central unit). The data transfer from one feedback module to the other one works on the principle of the bucket brigade device.

S88-3 English 6. Assembling the kit 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. Resistors Resistors reduce current. ni k The separate electronic components have the following special features you should take into account in assembling: Value: 1 k 4,7 k 100 k el ek tro The value of resistors for smaller power ratings is indicated through colour rings. Every colour stands for another figure.
English S88-3 Ceramic capacitors Among other things ceramic capacitors are used for filtering interference voltages or as frequency determining parts. Ceramic capacitors are not polarized. ni k Normally they are marked with a three-digit number which indicates the value coded. The number 104 corresponds to the value 100 nF. Transistors tro Transistors are current amplifiers which convert low signals into stronger ones. There are several types in different package forms available.
S88-3 English 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 separated any time. RJ-45 sockets ni k The RJ-45 sockets are standardized and are made to connect commercial Ethernet patch-cables (or RJ-45 cables).

S88-3 English Assembly Proceed according to the order given in the list below. First solder the components on the solder side of the PCB and then cut the excess wires with the side cutter. 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.
English S88-3 Solder pin 8. Terminal strips 9. RJ-45 sockets Insert the ICs into the soldered socket. Do not touch the ICs without first discharging yourself by touching a radiator or other grounded metal parts. Do not bend the "legs" when inserting them into the sockets. Check that the markings on the PCB, the socket and the IC show to the same direction. el ek Performing a visual check tro ni 10. ICs in DILhousing Put together the double terminal strips before mounting them. k 7.
S88-3 English 7. Connecting the S88-3 The S88-3 has two RJ-45 sockets (IN, OUT) to connect commercial Ethernet patch-cables (RJ-45 cables), which allow an interference free connection to other feedback modules or digital devices. ni k Use a 6-conductor connecting cable for the connection of digital devices or upstream customary feedback modules which you connect to the 6pole connector of the S88-3. Alternatively you can use an adapter S88A (optional extra) for the connection via a patch-cable.
English S88-3 Earth connection In systems with continuous mass (e.g. 3 rail systems fed with boosters with continuous mass) the earth connection between s88 feedback module and other components is made via the earth line in the s88 bus cable. Pin assignment tro ni k In digital layouts with boosters galvanically separated, the earth connection X2 of the S88-3 module has to be connected to a separate earth line or to mass of the rails.

English S88-3 8. Check list for troubleshooting Parts are getting too hot and/or start to smoke. The central unit, the memory or the interface do not show the proper status. Possible cause: The connection(s) between the feedback module and feedback modules connected in series or the digital device are interrupted. à Check the connections. When using a ribbon cable, check as well, if the connecting socket of the ribbon cable is put on in the right direction.
