PZS-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 PZS-2 Checking the package contents For assembling the kit you need: tro 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).
PZS-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. 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 PZS-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.
PZS-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. 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.
PZS-2 English 4. Operation overview Traffic between two terminus stations ni k The module controls the shuttle-train traffic between two terminus stations of an analogue d.c. model railway layout. At the second terminus station points can be connected. This allows the alternating traffic of two trains on the shuttle-train section. One additional stop can be added in each direction of traffic between the terminus stations. el ek Extra halts tro The shuttle-train traffic runs automatically.
English PZS-2 The length of the phases is adjusted at a trimmer, the settings are saved in an IC. Manual operation ni k The halt at the terminus stations, the stops and the extra halts can be prolonged by connecting the corresponding input of the module to earth. Then the train stops at the next station, stop or halt as long as the input is connected to earth (at least so long as programmed for the particular halt).
PZS-2 English Power supply k The module has to be supplied via a transformer not in use as driving transformer. Note: Driving transformers providing an additional output for further accessories are not suitable to supply both rails and module, as they internally contain only one transformer. Note: It is possible to supply the module via a transformer used to supply other accessories as the rails (e.g. lighting).
English PZS-2 Example for a shuttle-train traffic controlled by a PZS-2 In order to use the PZS-2 it is sufficient to connect the two terminus stations. All other extensions are optional. tro ni k By connecting a second rail at terminus station 2 it is possible to run two trains alternatingly. In order to switch between the two rails an extra bistable relay (not included in the package) has to be mounted.

English PZS-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. Resistors Resistors reduce current.
PZS-2 English Ceramic capacitors Among other things ceramic capacitors are used for filtering interference voltages or as frequency determining parts. Ceramic capacitors are not polarized. k Normally they are marked with a three-digit number which indicates the value coded. Electrolytic capacitors ni The number 104 corresponds to the value 100 nF. 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 PZS-2 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.
PZS-2 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 PZS-2 Fuses ni Terminal strips k Fuses interrupt a current circuit, when the current exceeds a certain strength of current for a set time. In this way they protect the circuit from damage due to overheating, resulting from an excess current flowing for a longer period. Excess current can be caused by overload or a short circuit. ta m s el ek tro Terminal strips are solder-in screw-type terminals.

PZS-2 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 PZS-2 Rectifier Observe the polarity! The pin connections are printed on the housing. The longer connecting pin is the positive pole. 8. Electrolytic capacitors Observe the polarity! One of the two leads (the shorter one) is marked with a minus sign. 9. Voltage regulator Observe the polarity! The cross section of voltage regulators in SOT-packages is shown in the PCB layout. With voltage regulators in TO-packages the unlabelled back side is marked in the PCB layout by a thick line.
PZS-2 English Performing a visual check Perform a visual check after the assembly of the module and remove faults if necessary: tro 7. Functional test ni k Remove all loose parts, wire ends or drops of solder from the PCB. Remove all sharp wire ends. Check that solder contacts which are close to each other are not unintentionally connected to each other. Risk of short circuit! Check that all components are polarised correctly. When you have remedied all faults, go on to the next part.

PZS-2 English 8.2. Dividing the shuttle-train section into parts The halts at the terminus stations and the two stops are initiated when the train has come into the respective section and the accessory track busy indicator has indicated the train coming in. The division of the shuttle-train section should be done as follows: tro ni k At least into the parts: terminus station 1 and terminus station 2. If neccessary into the additional parts: stop 1 and / or stop 2.
English PZS-2 ! Caution: Do not use the driving transformer for supplying the PZS-2! k When supplying the circuit via a transformer used as a driving transformer as well, short circuits can occur and possibly damage the circuit irreparably. The integrated fuse is without effect against short circuits of this type.
PZS-2 English 8.4. Connecting the shuttle-train section to the PZS-2 You must make at least the following connections (marked grey in the list): ni k Supplying transformer for the PZS-2 (s. section 8.3) Driving transformer (s. section 8.3) Terminus station 1 and 2 The other connections should be made only if required.
PZS-2 ta m s el ek tro ni k English Page 28
PZS-2 English ta m s el ek tro ni k Connecting points In case you do not use stop-points you should connect an extra bistabile relais 12 V (or a relay circuit board RL-2) to the points. The bistable relais switches on the power supply for the one rail in terminus station 2 while switching off the power supply for the other rail. If neither stop-points nor a bistabile relais are connected both rails are constantly supplied with power.
English PZS-2 Connecting stop diodes ni Connect them to the right rail – seen in the train´s direction of travel. Cut the rail that way that all current collectors driving the motor have passed the cut-off before the train reaches the end of the rails. k In order to prevent trains running beyond the end of the rails in the terminus stations 1 and 2, you can install extra stop diodes. tro 9.
PZS-2 English Traffic with one train Caution: When switching on the shuttle-train control, the train should be standing in the terminus station 1. If it is standing in the terminus station 2 it runs in direction of travel "way there" against the buffers. Traffic with two trains ni k Caution: When switching on the shuttle-train control one train should be standing in the terminus station 1.
English PZS-2 Extra halts By connecting the switching input "extra halts" to earth an extra halt is released immediately and independent of the place where the train momentarily is. In order to close the earth contact you can use switches or external circuits (e.g. signal control circuits). ta m s el ek tro ni k N.B: The length of the phases accelerating, halt and braking is set jointly for all extra halts.
PZS-2 English 10. Programming the PZS-2 Programming the length of the phases is done the same way for the five different stops (two terminus stations, two stops, all extra halts). Carry out the programming steps 1 to 3 for all stops you want to program. k Programming step 1: Choosing a stop tro ni Intermittently earth the programming input "select" (15) to point (4). The LED on the module flashes and thus indicates the 1 st stop is ready to be programmed.
English PZS-2 Programming step 2: Setting the phases´length By adjusting the trimmer you set the length of the phases accelerating, halt and braking for the 5 stops. In state of delivery the phases are set to the shortest possible length. Test the module with these settings first. Choose the stop you want to program (see programming step 1) and prolong the phases by turning the adjusting screw to the right. Phase Min. length (approx.) tro Trimmer ni k N.
PZS-2 English Programming step 3: Saving the settings After having set the phases´ length for a stop at the trimmer, connect the programming input "save" (14) to earth (4) intermittently. ni k N.B: Before closing the earth contact make sure the LED on the module flashes. If it does not the module is not in the programming mode and you cannot save any settings. The number of the light pulses between the pauses indicates for which stop the settings at the trimmer are saved.
English PZS-2 11. Check list for troubleshooting Parts are getting too hot and/or start to smoke. ! Disconnect the system from the mains immediately! ni k Possible cause: one or more components are soldered incorrectly. In case you have mounted the module from a kit, perform a visual check ( section 6.) and if necessary, remedy the faults. Otherwise send in the module for repair. The train stops, restarts, stops again, and so forth.
PZS-2 English In a terminus station the train runs against a buffer. Possible cause: The cuts are placed badly or the sections are connected the wrong way. Check the placing of the cuts and the connections of the sections. k Possible cause: When switching on the shuttle-train control the train (or both trains) was (were) standing in terminus station 2. ni Hotline: If problems with your module occur, our hotline is pleased to help you (mail address on the last page).
