KSM-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 KSM-3 Checking the package contents Please make sure that your package contains: k one kit, containing the components listed in the parts list ( page 19) and one PCB or one ready-built module or one ready-built module in a housing (complete unit), a CD (containing the manual and further information). ni Required materials For assembling the kit you need: tro an electronic soldering iron (max.
KSM-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. 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 KSM-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.
KSM-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. Caution: ni ! k 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 ta m s el ek tro ni 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 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.
KSM-3 English 4. Operation overview Loop problems k At the loop points in two-rail-systems, different polarities meet with each other. As soon as a vehicle bridges the differently polarized sections when driving in or out the terminal loop a short circuit occurs. ta m s el ek tro ni In digital layouts loop modules generally have to adapt the polarity within the terminal loop to the one outside.
English KSM-3 Mode of operation of the KSM-3 ni k As soon as a locomotive bridges the sectioning point between differently poled sections inside and outside the loop, the KSM-3 changes the polarity within the terminal loop. The response time is extremely short, as the KSM-3 already detects the voltage drop at the switchover to a short-circuit. In consequence, the KSM-3 is able to react within milliseconds before the voltage breaks down due to the short circuit.
KSM-3 English Phase 2: When the train running into the loop arrives at the sectioning point behind the points, the polarity within the loop is altered (if necessary). ta m s el ek tro ni k Phase 3: When the train running out of the loop arrives at the sectioning point before the points, the polarity within the loop is altered and at the same time the points are set properly for the train to run out of the terminal loop. Fig.
English KSM-3 Designing a layout with the KSM-3 The rails in the loop´s inside between the two sectioning points have to be at least as long as the longest train to pass the terminal loop. k The circuit also works properly when there are several trains within the loop at the same time provided that there are not two locomotives passing the sectioning points simultaneously. This allows branching rails within in terminal loop, for example.

English KSM-3 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 tro Resistors reduce current. ni k The separate electronic components have the following special features you should take into account in assembling: The value of resistors for smaller power ratings is indicated through colour rings. Every colour stands for another figure.
KSM-3 English 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 224 corresponds to the value 220 nF. Electrolytic capacitors tro Electrolytic capacitors are often used to store energy. In contrast to ceramic capacitors they are polarized. The value is given on the package.
English KSM-3 Light emitting diodes (LEDs) 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). ni k Light emitting diodes should always be connected via a series resistor which limits the current and prevents failure. With circuits designed for the connection of LEDs the series resistors are often integrated on the circuit board.
KSM-3 English Integrated circuits (ICs) Depending on the type, ICs fulfil various tasks. The most common housing form is the so-called "DIL"-housing, from which 4, 6, 8, 14, 16, 18 or more "legs" (pins) are arranged along the long sides. tro Microcontrollers ni k ICs are sensitive to damage during soldering (heat, electrostatic charging). For that reason in the place of the ICs IC sockets are soldered in, in which the ICs are inserted later.
English KSM-3 Screw terminals Screw terminals provide a solder-free and safe connection of the cables to the circuit, which can still be separated any time. ni k Terminal strips are available as single or double row versions with 2 or 3 poles (resp. 2x2 or 2x3 poles). Connections with any number of poles can be created by linking several terminal strips. In order to fix them the connecting cables are inserted and screwed (similar to a lustre terminal).

English KSM-3 Connecting points Connecting points to the KSM-3 is optional. You can do without when you do not intend to switch the points automatically. k Each of the two isolating points is assigned firmly to one position of points. If the position is "branch" or "straight" depends on the particular mounting situation. tro ni For that reason you have to check after having connected them if the points switch "correctly", when the locomotive passes the isolating points on its way out of the loop.
