English GBM-8 1. Getting started How to use this manual This manual gives step-by-step instructions for safe and correct assembly of the kit and fitting of the 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. Keep this manual safely so that you can solve problems in the future.
GBM-8 English Checking the package contents Please make sure that your package contains: § one kit, containing the components listed in the parts list and one PCB, § or one ready-built module, § or one complete unit (ready-built module in a housing, § one manual. Required materials For assembling the kit you need: § § § § § § § an electronic soldering iron (max.
English GBM-8 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.
GBM-8 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. Use a suitable soldering iron stand. Never leave a hot soldering iron or station unattended. Thermal danger A hot soldering iron or liquid solder accidentally touching your skin can cause skin burns.
English GBM-8 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. § § § § § § § § § Use a small soldering iron with max. 30 Watt. Keep the soldering tip clean so the heat of the soldering iron is applied to the solder point effectively. Only use electronic tin solder with flux.
GBM-8 § English After placing the parts, please double check for correct polarity. Check the PCB tracks for solder bridges and short circuits created by accident. This would cause faulty operation or, in the worst case, damage. You can remove excess solder by putting a clean soldering tip on the spot. The solder will become liquid again and flow from the soldering spot to the soldering tip. 4. Operation overview The track busy indicator GBM-8 can be used in analogue (d.c. or a.c.
English GBM-8 Evaluating and displaying the busy messages As soon as the GBM-8 detects an electric current consumer in a connected track section, the linked output is internally connected to the output M. This way, the output of the GBM-8 works like a switch switching to earth. Especially in analogue displays, you can display the busy messages with LEDs (together with suitable series resistors) connected to the outputs. The outputs of the GBM-8 are suitable for a load of maximum 50 mA each.
GBM-8 English 6. Assembling the GBM-8 You can skip this part if you have purchased a ready-built module or a complete unit. 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 is indicated through colour rings.
English GBM-8 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. Integrated circuits (ICs) Depending on the type, ICs fulfil various tasks. They are polarized and therefore have to be mounted in a certain direction.
GBM-8 English Assembling the kit ! Caution: Diodes, transistors, Ics and opto couplers should be inserted in the right direction! If you solder them the wrong way around the affected parts can be damaged when you connect the power. In the worst case the whole circuit can be damaged. At the best, a wrongly connected part will not function. Start the assembly with the resistors. First solder the components on the solder side of the PCB and then cut the excess wires with the side cutter.
English GBM-8 Performing a visual check Perform a visual check after the assembly of the module and remove faults if necessary: § 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.
GBM-8 English Repeat the test for all other track sections. Be sure to connect the connections for the power supply, the rails and the output, which are assigned to each other (e.g. V3a, V3b, G5 and A5). If the funcitional test is not successful for one or several outputs, check if the opto-couplers and the diodes have been mounted polarized correctly. Follow the hints in section 8, as well. ! Caution: When a component gets too hot, disconnect the module immediately from the power supply.
English GBM-8 Follow the connections diagrams fig. 4, 5 and 6. Connecting the power supply Connect the connections for the power supply of the GBM-8 (V1a and V1b or V2a and V2b etc.) to the rail outputs of the driving transformer (in analogue layouts) or the rail outputs of the boosters (in digital layouts). The polarity is not of importance.
GBM-8 English supply of the LEDs but a separate transformer, for instance one used to supply other lighting circuits. When connecting the LEDs to an a.c. transformer, you should mount an additional damping diode (e.g. 1N400x, x=2...7) and a capacitor with a value between 10 and 100 µF and an electrical strength of minimum 25 V according to fig. 5. ! Caution: Never connect electric light bulbs to the outputs as these consume more than 50 mA current, as a rule.
English GBM-8 8. Check list for troubleshooting § Parts are getting too hot and/or start to smoke. § Possible cause: one or more components are soldered incorrectly. à In case you have mounted the module from a kit, perform a visual check (à section 6.) and if necessary, remedy the faults. Otherwise send in the module for repair. The LEDs connected to the module do not light. Possible cause: The voltage supply has been interrupted. à Check the connection from the module to the transformer.
GBM-8 English 9. CE and Warranty Certification (CE) This product is developed and tested in accordance with the European standards EN 55014-1 and EN 61000-6-3. This product conforms with the EC-directive 2004/108/EG on electromagnetic radiation and is therefore CE certified. To guarantee the electromagnetic tolerance in operation you must take the following precautions: § § § Connect the transformer only to an approved mains socket installed by an authorised electrician.
English GBM-8 The following invalidate the warranty: § § § § § § § § § § § § § using an unsuitable soldering iron, solder containing liquid acids or similar, if the kit is assembled and soldered poorly, or if damage is caused by not following the instructions in this manual, if the ready-built module has been altered and repair attempts have failed, if arbitrary changes in the circuit are made, if components are removed or swapped, or wiring is added or removed in any other way as layed down in the ori
