    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. Visibly damaged parts can cause unpredictable danger. Do not use damaged parts: recycle and replace them with new ones. Electrical hazards ...
  • Page 6 English PZS-2 Fire risk 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.

  • Page 7: Safe And Correct Soldering

    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 Caution: Incorrect soldering can cause dangers through fires and heat. Avoid these dangers by reading and following the directions given in the chapter Safety instructions.
  • Page 8 English PZS-2  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.

  • Page 9: Operation Overview

    PZS-2 English 4. Operation overview Traffic between two terminus stations 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.
  • Page 10 English PZS-2 The length of the phases is adjusted at a trimmer, the settings are saved in an IC. Manual operation 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.
  • Page 11 PZS-2 English Power supply 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.
  • Page 12 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. By connecting a second rail at terminus station 2 it is possible to run two trains alternatingly.

    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. The separate electronic components have the following special features you should take into account in assembling: Resistors Resistors reduce current.
  • Page 15 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. Normally they are marked with a three-digit number which indicates the value coded. The number 104 corresponds to the value 100 nF. Electrolytic capacitors Electrolytic capacitors are often used to store energy.
  • Page 16 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). Light emitting diodes should always be connected via a series resistor which limits the current and prevents failure.
  • Page 17 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. ICs are sensitive to damage during soldering (heat, electrostatic charging).
  • Page 18 English PZS-2 Fuses 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.

  • Page 26 English PZS-2 Caution: Do not use the driving transformer for supplying the PZS-2! 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.

  • Page 29 PZS-2 English 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.

  • Page 30: Operation

    English PZS-2 Connecting stop diodes 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. Connect them to the right rail – seen in the train´s direction of travel.
  • Page 31 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 Caution: When switching on the shuttle-train control one train should be standing in the terminus station 1.
  • Page 32 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). N.B: The length of the phases accelerating, halt and braking is set jointly for all extra halts.

  • Page 33: Programming The Pzs-2

    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.
  • Page 34 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.
  • Page 35 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. N.B: Before closing the earth contact make sure the LED on the module flashes.
