SV-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 SV-2 Required materials For assembling the kit you need: k an electronic soldering iron (max. 30 Watt) or a 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). tro For testing the module you need points. ni ta m s el ek In order to connect the module you need wire.
SV-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 SV-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.
SV-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. 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.
SV-2 English 4. Operation overview The switching amplifier provides the energy to switch points with double solenoids. Applications: tro ni k Switching stiff points. It is possible to switch stiff points independent of the power of the transformer. Simultaneously switching several points. Each of them has to be connected to a switching amplifier of its own and then all points can be switched simultaneously via one impulse. The switching amplifier works, drastically simplified, like a flash gun.
English SV-2 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. ni k The separate electronic components have the following special features you should take into account in assembling: Resistors Value: 120 1 k Diodes el ek tro Resistors reduce current. Their mounting orientation is of no importance.
SV-2 English Electrolytic capacitors Electrolytic capacitors are often used to store energy. In contrast to ceramic capacitors they are polarized. One of the two leads is marked with a minus sign which indicates the mounting orientation. The value is given on the casing. ni k Electrolytic capacitors are available with different voltage sustaining capabilities. Using an electrolytic capacitor with a voltage sustaining capability higher than required is always possible.

First solder the components on the solder side of the PCB and then cut the excess wires with the side cutter.
SV-2 English 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. At the best, a wrongly connected part will not function. Resistors Mounting orientation of no importance. 2. Diodes Observe the polarity! The negative end of the diodes is marked with a ring. This is shown in the PCB layout. 3. PCB sockets 4.
English SV-2 7. Connecting the SV-2 Do not mount the switching amplifier in your model railroad layout yet. Perform a functional test with the test points. It is recommended to perform the functional test even if you have purchased a ready-built module. k Connecting the switching amplifier ni Connect the switching amplifier according to the connections diagram 1 and the following list. Coil 1 of the points W2 Common connection of the coils W3 Coil 2 of the points GND With connection to a.c.
SV-2 English el ek tro ni k Connections 1 Testing the switching amplifier ta m s Connect temporally the sockets "GND" and "S1" with one another. The points should switch now. If the points do not switch they are possibly in the corresponding position. Switch the points by hand in the other position and try to switch the points again. Then connect "GND" to "S2". The points should switch again. Please note: You have to wait for a moment (approx. 2 sec.
English SV-2 Simultaneous switching of several points You can switch several points simultaneously if each is connected to its’ own switching amplifier. Switch the switching amplifiers´ inputs commonly via a push button, control panel, circuit track or similar.
SV-2 English 8. Check list for troubleshooting Parts are getting too hot and/or start to smoke. ! Disconnect the system from the mains immediately! el ek tro ni k Possible cause: one or more components are soldered incorrectly. à In case you have mounted the module from a kit, perform a visual check (à section 6.) and if necessary, remedy the faults. Otherwise send in the module for repair. The points connected for the test cannot be switched.
English SV-2 9. Guarantee bond ni k For this product we issue voluntarily a guarantee of 2 years from the date of purchase by the first customer, but in maximum 3 years after the end of series production. The first customer is the consumer first purchasing the product from us, a dealer or another natural or juristic person reselling or mounting the product on the basis of selfemployment. The guarantee exists supplementary to the legal warranty of merchantability due to the consumer by the seller.
SV-2 English 10. EU declaration of conformity This product conforms with the EC-directives mentioned below and is therefore CE certified. ni Connect the transformer only to an approved mains socket installed by an authorised electrician.
