WBA-1/WBA-2 English How to use this manual If you have no specialist technical training, this manual gives step-bystep instructions for safe and correct assembly of the kit and fitting 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 FAQ chapter. You will then know where to take care and how to prevent mistakes which take a lot of effort to correct.
English WBA-1/WBA-2 § short circuits, § connecting the circuit to another voltage than specified, § impermissibly high humidity and condensation build up can cause serious injury due to electrical shock. Take the following precautions to prevent this danger: § Never perform wiring on a powered module. § Assembling and mounting the kit should only be done in closed, clean, dry rooms. Beware of humidity. § Only use low power for this module as described in this manual and only use certified transformers.
WBA-1/WBA-2 English Dangerous environments A working area that is too small or cramped is unsuitable and can cause accidents, fires and injury. Prevent this by working in a clean, dry room with enough freedom of movement. Other dangers Children can cause any of the accidents mentioned above because they are inattentive and not responsible enough. Children under the age of 14 should not be allowed to work with this kit or the ready-built module.
English WBA-1/WBA-2 Operation overview The module is a so-called "astable multivibrator". Two transistors on the PCB serve as switches and alternately switch the power supply for the connected LEDs on and off: When the one switch (transistor) is opened, the other one is closed. As long as the switch is open, electric energy is saved in the respective capacitor. As soon as the capacitor is charged, the circuit is switched: The switch closes and the capacitor belonging to the other switch starts to charge.
WBA-1/WBA-2 English Checking the package contents Check the contents of the package for completeness immediately after unpacking: § one kit, containing the components listed in the parts list (see page I) and one PCB or § one ready-built module, § one manual. Required tools and consumables Make sure you have the following tools and consumables ready for use: § § § § § § an electronic soldering iron (max.
English WBA-1/WBA-2 § Only use electronic tin with flux. § When soldering electronic circuits never use soldering-water or § § § § § § § soldering grease. They contain acids that can corrode components and copper tracks. Solder quickly: holding the iron on the joints longer than necessary can destroy components and can damage copper tracks or soldering eyes.
WBA-1/WBA-2 English Assembling the kit You can skip this part if you have purchased a ready-built module. 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 to prevent mistakes in assembling: Resistors Resistors reduce current. Their mounting orientation is of no importance. The value of resistors for smaller power ratings (under 5 W) is indicated through colour rings.
English WBA-1/WBA-2 Transistors Transistors are current amplifiers which convert low signals into stronger ones. They have three contacts. As they are polarized, they have to be mounted in a certain direction. BC-Types have a housing in form of a half cylinder (SOThousing). The cross section is shown in the PCB Layout which determines the mounting orientation. PCB sockets The widely spread 2,6 mm model railway connectors fit exactly to the sockets.
WBA-1/WBA-2 English The following points are inapplicable if you have purchased a readybuilt module. § 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.
English ! WBA-1/WBA-2 Caution: If a component gets too hot, disconnect the module and power supply from the mains immediately. Possible short circuit! Check the assembly! After performing a successful functional test, disconnect power from the double flashlight. Disconnect the LEDs from the module and install the module. Proceed as described in the functional test. Connectings several LEDs to one output You can connect up to two LEDs in parallel to one output or several LEDs in series to one output.
WBA-1/WBA-2 English § The LEDs connected to the module do not light. Possible cause: One or several LEDs are connected in the wrong direction. à Change the direction! Possible cause: One or several LEDs are defective. à Check the LEDs. Possible cause: If connected to direct voltage the connections "GND" and "Uin" or "12V" are incorrectly connected. à Check the connections. § Only WBA-1: One or several LEDs seem to light permantly. Possible cause: The capacitors are not correctly soldered in.
