WBA-1 | WBA-2 | WBA-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 WBA-1 | WBA-2 | WBA-3 Required materials For assembling the kit you need: k ni 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), thin connecting wire. 2.
WBA-1 | WBA-2 | WBA-3 k Only use low power for this module as described in this manual and only use certified transformers. Connect transformers and soldering irons only in approved mains sockets installed by an authorised electrician. Observe cable diameter requirements. After condensation build up, allow a minimum of 2 hours for dispersion. Use only original spare parts if you have to repair the kit or the ready-built module.
English WBA-1 | WBA-2 | WBA-3 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. ni k ! Caution: Little children can swallow small components with sharp edges, with fatal results! Do not allow components to reach small children.
WBA-1 | WBA-2 | WBA-3 Observe correct polarity orientation of the parts before soldering. Solder quickly: holding the iron on the joints longer than necessary can destroy components and can damage copper tracks or soldering eyes. Apply the soldering tip to the soldering spot in such a way that the part and the soldering eye are heated at the same time. Simultaneously add solder (not too much). As soon as the solder becomes liquid take it away.
English WBA-1 | WBA-2 | WBA-3 4. Operation overview The double flashlights WBA-1, WBA-2 and WBA-3 have been designed to control LEDs. The circuit´s two outputs are alternately switched on and off. Fields of application are e.g. St. Andrew´s crosses, the flash lights of emergency or roadworks vehicles or signal lamps. k Flashing frequency tro ni The flashing frequency of the double flashlights WBA-1 and WBA-2 cannot be altered. Due to component tolerances it is 1 to 2 Hz.

WBA-1 | WBA-2 | WBA-3 English Electrolytic capacitors Electrolytic capacitors are often used to store energy. In contrast to ceramic capacitors they are polarized. The value is given on the package. 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.

WBA-1 | WBA-2 | WBA-3 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 a 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 WBA-1 | WBA-2 | WBA-3 Performing a visual check Perform a visual check after the assembly of the module and remove faults if necessary: tro 7. Connecting the double flashlight 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.
WBA-1 | WBA-2 | WBA-3 English Connection to the power supply Connect the double flashlight according to the figures and the list, to the power supply. When connecting the PCB to (analogue) a.c. voltage, the connections´polarity is not relevant. When connecting the PCB to (analogue) d.c. voltage, you have to observe the connections´ polarity. - 12V (WBA-1) Uin (WBA-2) U+/~ (WBA-3) + Polarity not relevant el ek tro GND a.c. voltage ni d.c.
English WBA-1 | WBA-2 | WBA-3 Info: Light emitting diodes (LEDs) k 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). The longer lead of wired LEDs is normally the anode (positive pole). With SMD-LEDs the cathode normally is shown by a mark on the housing. tro ni When using LEDs you always have to limit the current conduction (e.g.
