English LD-G-32.2 and LD-W-32.2 1. Getting started How to use this manual ni k This manual gives step-by-step instructions for safe and correct fitting and connecting of the decoder, 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.
LD-G-32.2 and LD-W-32.2 English Checking the package contents ni k Please make sure that your package contains: one or five locomotive decoders, depending on the version with or without soldered connecting wires resp. with or without interface connector; a CD (containing the manual and further information). N.B. For technical reasons it is possible that the PCB is not completely inserted. This is not a fault. tro Available versions Connecting wires / Interface LD-G-32.2 LD-W-32.
English LD-G-32.2 and LD-W-32.2 In order to connect decoders without interface or soldered connecting wires you will need wire. Recommended cross sections: > 0,04 mm² for the connections to the function outputs; > 0,05 mm² for the connections to the motor and current collectors. If you want to connect a decoder LD-G-32.2 to an a.c. motor you need: k ni a load control adapter LRA (item no. 70-02105 or 70-02106) or a permanent magnet (e.g. item no.
LD-G-32.2 and LD-W-32.2 English Electrical hazards Fire risk tro el ek Never perform wiring on a powered module. Assembling and mounting the kit should only be done in closed, clean, dry rooms. Beware of humidity. 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.
English LD-G-32.2 and LD-W-32.2 Thermal danger A hot soldering iron or liquid solder accidentally touching your skin can cause skin burns. As a precaution: k use a heat-resistant mat during soldering, always put the hot soldering iron in the soldering iron stand, point the soldering iron tip carefully when soldering, and remove liquid solder with a thick wet rag or wet sponge from the soldering tip.
LD-G-32.2 and LD-W-32.2 English 3. Safe and correct soldering ni ta m s tro 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. When soldering electronic circuits never use soldering-water or soldering grease. They contain acids that can corrode components and copper tracks.
English LD-G-32.2 and LD-W-32.2 4. Operation overview 4.1. Modes of operation Digital operation k The locomotive decoder is a multiple protocol decoder, that can operate with and automatically recognise both DCC or Motorola formats. ni The number of addresses is dependant on the format being used: el ek tro Motorola-Format: 255 addresses, DCC-Format: 127 Basis-addresses or 10.239 extended addresses. In the DCC format the decoder can be driven in all speed levels (14, 28 or 128).
LD-G-32.2 and LD-W-32.2 English Analogue mode Caution: ni ! k The locomotive decoder can also be used in analogue model railway layouts run with a D.C. speed control, and with restrictions with an A.C. speed control. When putting the vehicle on the rails the decoder recognizes automatically if it is run in analogue or digital mode and sets the corresponding operation mode. The automatic recognition of the analogue mode can be switched off. el ek tro Old analogue driving transformers (e.g.

PWM Suitable for coreless (Faulhaber) motors LD-G-32.2 32 kHz (fixed) yes LD-W-32.2 480 or 60 Hz (to be set) ni k Decoder type tro no Load control el ek The LD-G-32.2 for DC motors has a load control, the LD-W-32.2 for AC motors do not have this function.
LD-G-32.2 and LD-W-32.2 English KI: The integral component of the load control ensures the remaining difference between the set and the present value is reduced to 0 and so for the correction of very small divergences. If the set value is too high the locomotive stutters massively while moving. Velocity characteristic ni k KD: The differential component of the load control ensures that the control is not converted too quickly. Is the set value to low then the locomotive stutters.
English LD-G-32.2 and LD-W-32.2 Emergency stop It is possible to carry out an emergeny stop at a change of direction automatically, when so programmed. 4.3. Function outputs tro ni k The decoder has function outputs, which are available to connect optional accessories (e.g. lighting, smoke generator, sound module, electric coupling).
LD-G-32.2 and LD-W-32.2 English 4.4. Releasing the functions The function outputs can be released by pushing the function keys. The mapping of the outputs to the function keys and the switching inputs is arbritary. It is possible to assign several function keys and switching inputs to one output.

English LD-G-32.2 and LD-W-32.2 4.6. Feedback with RailCom** k RailCom is a log for bi-directional communication in digital model railway layouts controlled in DCC-format. It allows e.g. the feedback of the address and the CV values from the decoder to the digital central unit or to special receivers (so-called detectors). The decoders must be designed to send the RailCom messages. tro ni When so programmed, the locomotive decoders LD-G-32.2 and LD-W32.

LD-G-32.2 and LD-W-32.2 English 6.3. Using decoders with interface connectors Many recent locomotives with d.c. motor are equipped ex works with an interface socket. Using a decoder with a suitable connector saves separating the connections and soldering works at the locomotive.
English LD-G-32.2 and LD-W-32.2 6.5. Mounting decoders without interface k Locate the position for the decoder after opening the locomotive housing. Disconnect the motor from the rail current collectors or the change-over switch from the motor and rails if you have a locomotive with electronic change-over switch. The change-over switch is no longer necessary, you can remove it.
English k LD-G-32.2 and LD-W-32.2 tro Connecting accessories to the outputs ni Fig. 2: Connection of an a.c. motor and the power supply el ek Disconnect any existing diodes in the leads to the lamps, otherwise the lamps might not light. Connect the lamps and the accessories to the function outputs of the decoder. If the lamp or the accessory is already connected with one side to vehicle ground, the connection is complete.
English LD-G-32.2 and LD-W-32.2 6.6. Connecting LEDs to the function outputs The decoder´s function outputs switch respective to the decoder ground. For that reason you must connect the cathodes (-) of the LEDs to the function outputs and the anodes (+) to the decoder´s common return conductor for all function outputs.
LD-G-32.2 and LD-W-32.2 English connection first add the forward voltages of all LEDs. The forward voltages depend on the lighting colour and should be given in the technical specifications. In case there is no manufacturer information available, you can take as a basis 4 V for white and blue LEDs and 2 V for yellow, orange, red and green LEDs. k The remaining voltage has to be "eliminated" by a resistor.
English LD-G-32.2 and LD-W-32.2 6.7. Connecting inductive loads 6.8. Connecting accessories via a relay k When connecting inductive loads (e.g. TELEX couplings, relays or other accessories with coils), you should switch a free-wheeling diode (e.g. 1N400x) in parallel, in order to avoid damage at the output. Check to connect the anode of the diode to the function output.
LD-G-32.2 and LD-W-32.2 English 6.9. Connecting a buffer capacitor In sections with bad contact to the rails the power supply of the decoder can be interrupted. Possible consequences are e.g. flickering lighting. In these and similar cases you can find a remedy by connecting a buffer capacitor. tro 6.10. Fixing the decoder ni k The electrolytic capacitor should have a capacity of minimum 100 µF and a proof voltage of minimum 35 V.
English LD-G-32.2 and LD-W-32.2 7. Programming Programming with DCC central units tro ni k You can program the configuration variables (CV) of the decoder from the digital central unit, you can use main track programming as well. See the chapter in the manual of your central unit where the byte wise programming of configuration variables (CVs) (Direct programming) and main track programming (POM) are explained.
