LC modules 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 LC modules Checking the package contents For assembling the kit you need: 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).
LC modules English In addition, you possibly need for the following versions of the LCmodules: k ni tro el ek ta m LC-module 16: For the connection of accessories with a current consumption of more than 100 mA to output 1: a monostable relay 1xUm 12 V (e.g. item-no. 84-61010-01) and a protective diode 1N400x, x > 1. LC-module 18: a loudspeaker (recommended impedance > 32 Ohm, e.g. item no. 70-03121-01).
English LC modules 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.
LC modules English 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.
English LC modules 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.
LC modules k ni tro ta m el ek 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.
English LC modules 4. Operation overview The Light Computer is controlled by a micro controller. The program stored in the micro controller controls the five outputs of the module. Sequence and timing are different with the various versions. the program finishes after one cycle or is repeated endlessly; the one or the other version of the program will be displayed. tro ni k The LC module has a switching input (JP2) which has effects on the program sequence with some versions.
LC modules English LC-4 "Building site flasher": At the five outputs a running light sequence is created. If the input JP2 is switched to earth, the light sequence switches off after the completion of the program. If the input remains open, the program repeats continuously. ni k LC-5 "Flickering flame": At the five outputs an irregular light pattern is created. If red and yellow bulbs are connected, the appearance of a flickering flame results.
English LC modules LC-8 "Advertising light 4": Fusion of the advertising lights 1 to 3, coming on one after the other. If the input JP2 is switched to earth, the light sequence switches off after the completion of the active part of the program. If the input JP2 is switched to earth, the light sequence is interrupted. If the input remains opens, the program is repeated constantly.
LC modules English goes on for a short time at irregular intervals. By the end of the program the lights in the bedroom (output 5) and in the bathroom go on for some time, the bulbs connected to outputs 2 and 3 switch off. tro ni k Program 2: In the entrance-hall (output 1) the light goes on for a short time at irregular intervals. The offices (or the flats in a multiple family dwelling) are connected to the outputs 2 to 5.
English LC modules LC-16 "Dim switch for street lamps": The input JP2 is switched on and off automatically via a light sensitive switch. The sensitivity of the switch is set via a trimpot. k Four outputs are designed for the connection of street lamps. The street lamps are getting brighter gradually after being switched on and obtain their maximum brightness after about one minute. Additional accessories (e.g.
LC modules English k In the program "moving vehicle": The front and back lights are always switched on. It is possible to connect a loudspeaker as a horn (not included) to output 3, the volume can be reduced by connecting a series resistor (approx. 10 to1 k). The flashing lights on the left and the right, the horn and the stop lights are switched on and off at random.
English LC modules ni k LC-21 "Funfair flow effect lighting 1": The 5 outputs generate a light flow sequence. After the first run through the output 5 stays on, after the second run through the output 4, and so on, so that after 5 cycles all connected lamps or LEDS are switched on. With the cycles 6 to 10 the outputs are switched off in reverse order. If the input JP2 is switched to earth, the light sequence switches off after the completion of the active part of the program.

English LC modules Resistors Resistors reduce current. The value of resistors for smaller power ratings is indicated through colour rings. Every colour stands for another figure. Colour rings: brown - black - red (gold) brown - black - orange (gold) Electrolytic capacitors tro Value: 1 k 10 k ni k Carbon film resistors have 4 colour rings. The 4th ring (given in brackets here) indicates the tolerance of the resistor (gold = 5 %). el ek Electrolytic capacitors are often used to store energy.
LC modules English Transistors Transistors are current amplifiers which convert low signals into stronger ones. There are several types in different package forms available. The type designation is printed on the component. k Transistors for a low power rating (e.g. BC types, BS types) have a package in form of a half zylinder (SOTpackage).

English LC modules Connecting light bulbs As a rule you can connect one or two bulbs to one output. Bulbs are not polarized. Connect one side to the output, the other to the return conductor. tro Connecting LEDs ni k ! Caution: The maximum current of 100 mA per output should not be exceeded. In this case the output would be damaged. For that reason strictly uphold the specification of the current consumption (given in mA) on the bulb´s socket or it´s packaging.
English el ek tro ni k LC modules Parallel connection of LEDs ta m s With a parallel connection each LED has to be connected via it´s own series resistor to the output. The total current at the output results from summing up the current of each single LED. The current consumption of one LED depends on the value of the series resistor. The higher the value, the lower is the current and the more LEDs can be connected to one output.

English LC modules Tip: Connecting many LEDs to one LC module If you want to connect a great number of LEDs to one LC module (e.g. with advertising lights or funfair lights), best connect them as follows: ni k Connect so many LEDs in series as possible with the available operating voltage. When using an a.c. transformer of 18 V you can connect 7 white or blue or 11 different coloured LEDs in series. Reduce the current by using a series resistor as far as the LEDs´ brightness still matches your ideas.
