    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. Visibly damaged parts can cause unpredictable danger. Do not use damaged parts: recycle and replace them with new ones.
  • Page 7 LC modules English 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 8: Safe And Correct Soldering

    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. 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 9 LC modules 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.

  • Page 10: Operation Overview

    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. It is possible to connect lamps, LEDs or other circuits (if neccesary via relais) to the outputs.
  • Page 11 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. LC-5 "Flickering flame": At the five outputs an irregular light pattern is created.
  • Page 12 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.
  • Page 13 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. Program 2: In the entrance-hall (output 1) the light goes on for a short time at irregular intervals.
  • Page 14 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. 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.
  • Page 15 LC modules English 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.
  • Page 16 English LC modules 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.
  • Page 17 LC modules English The module can be freely cascaded, which means that it is possible to connect to one or several outputs further LC modules to be switched delayed. There are no restrictions concerning the number of LC-24 modules connected in series. This allows to switch time-delayd on and off the lightings for an entire model railroad layout with one switch.

  • Page 19 LC modules English Resistors Resistors reduce current. The value of resistors for smaller power ratings is indicated through colour rings. Every colour stands for another figure. Carbon film resistors have 4 colour rings. The 4th ring (given in brackets here) indicates the tolerance of the resistor (gold = 5 %).
  • Page 20 English LC modules 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. Transistors for a low power rating (e.g. BC types, BS types) have a package in form of a half zylinder (SOT- package).

  • Page 26: Connecting Leds

    English LC modules 7.3. Connecting LEDs You can connect several LEDs in parallel or serial (in series) to one output (see following sections). Which version fits better depends amongst others from the mounting situation. LEDs are polarized. Connect the cathode (-) to the output and the anode (+) to the return conductor.
  • Page 27 LC modules English Parallel connection of LEDs 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.
  • Page 28 English LC modules Serial connection of LEDs With a serial connection all LEDs have to be connected (in series) via one series resistor to the output. The current consumption of the LEDs depends on the value of the series resistor. The higher the value, the lower is the current.
