LD-G-3 / LD-W-3 English How to use this manual If you have no specialist technical training, this manual gives step-bystep instructions for safe and correct 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.
English LD-G-3 / LD-W-3 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. Electrical hazards § Do not touch powered, live components. § Do not touch conducting components which are live due to malfunction. § Avoid short circuits.
LD-G-3 / LD-W-3 English Fire risk Touching flammable material with a hot soldering iron can cause lifethreatening fire, burns and toxic smoke. Connect your soldering iron or soldering station only when actually needed. Use the correct soldering iron or station and 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 LD-G-3 / LD-W-3 EMC declaration This product is developed in accordance with the European standards EN 55014 and EN 50082-1, tested corresponding to the EC - directive 89/336/EWG (EMVG of 09/11/1992, electromagnetic tolerance) and meets legal requirements. To guarantee the electromagnetic tolerance you must take the following precautions: § Connect the transformer only to an approved mains socket installed by an authorised electrician.
LD-G-3 / LD-W-3 English Operation overview The decoder is designed for operation in Motorola I or II format and can be adjusted to one of 255 adresses. It evaluates the digital data sent by the central unit to its address and transmitts it to the locomotive. Function speed level and direction of motion The speed level set at the central unit and the change-direction command are transmitted to the locomotive by the decoder. At a direction change command, the current direction of travel is saved.
English LD-G-3 / LD-W-3 Shunting gear The auxiliary function F4 allows you to switch into the shunting gear mode. In the shunting gear mode the velocity of all speed levels is reduced to ca. 50 % compared to the standard velocity. Restrictions in Motorola I format The auxiliary functions F3 and F4 are not available in Motorola I format. Technical specifications Data format Supply voltage Current consumption (without connected loads) Max. current for motor Max. current per function output Max.
LD-G-3 / LD-W-3 § § § § § English a soldering iron stand with tip-cleaning sponge a small side cutter and wire stripper an electronic soldering iron (max. 30 Watt) with a fine tip tin solder (0,5 mm. diameter) wire (diameter: > 0,05 mm²) Safe and correct soldering ! Caution: Incorrect soldering can cause fires (through excessive heat). Avoid this danger by reading the chapter Safety instructions again and following the directions given. If you have had training in soldering you can skip this chapter.
English LD-G-3 / LD-W-3 Performing a visual check Damaged materials can cause injury. Parts damaged during transit can also be dangerous.Check the module for damage, missing parts or poor soldering. If you find damage, return the module for exchange. Mounting the locomotive decoder Open the locomotive housing. Locate the position for the decoder.
LD-G-3 / LD-W-3 English If the lamps are already connected with one side to locomotive ground, the connection is complete. If not, connect the second side of the lamps to the return conductor (point X1 resp. X6). ! Caution: The return conductor for all functions (point X1 resp. X6) must under no circumstances be connected to locomotive ground. Possible short circuit! The locomotive decoder will be damaged in operation.
English LD-G-3 / LD-W-3 Fixing the locomotive decoder After completing all connections fix the locomotive decoder with doublesided adhesive tape, for example. Using an NEM 652 interface connector Some locomotives already have an NEM 652 interface connector mounted. Using a convenient connecting plug you save disconnecting the connections and you do not need to solder at the locomotive. The list shows how to connect the contacts of the interface connector to the connecting points of the locomotive decoder.
LD-G-3 / LD-W-3 English Online-programming In the programming mode, the starting velocity, the maximum velocity as well as the acceleration and brake delay are tested and directly saved. For that reason you need an isolated oval section of track for programming. As soon as you finish a menu point, i.e. before you switch the function "function" to "off", you should always set the speed control knob to "0". Otherwise the locomotive starts to run at the beginning of the following menu point.
English LD-G-3 / LD-W-3 1. Programming the locomotive address After accessing the programming mode enter the present or the new locomotive address. It is not necessary to enter the old address if you intend to enter a new locomotive address. Confirm the input by switching on the function "function". The locomotive confirms the input by flashing the front lamp once. Set the speed control knob to "0". To access the following menu point, switch off the function "function". 2.
LD-G-3 / LD-W-3 English Skipping single menu points If you want to skip single menu points set the speed control knob to "0", and switch the function "function" on and off once. The decoder retains the driving characteristics that have already been saved. The decoder confirms the finishing of a menu point by flashing the front lamp of the locomotive. Depending on which menu point you finish, it flashes two, three or four times.
English LD-G-3 / LD-W-3 Switching the shunting gear The shunting gear can be switched on and off via the auxiliary function F4. In the shunting gear mode the velocity of all speed levels is reduced to ca. 50 % compared to the standard velocity. The change of the setting takes effect immediately. In Motorola I format the shunting gear cannot be activated. Improvement of the driving characteristics Locomotives with especially high current consumption or track sections with bad contacts (e.g.
LD-G-3 / LD-W-3 English § The locomotive lighting does not correspond to its direction of travel. Possible cause: The forward and backward light connections have been exchanged. à Check the connections. Possible cause: The connections of the motor to the points X10 and X11 have been exchanged. à Exchange the connections. § A lamp flickers (this is not a defect). Possible cause: The lamp is connected with one side to locomotive ground.
