tams elektronik LD-G-43 1. Getting started This manual will help you step by step to mount and commission the decoder safely and correctly. Before you connect the decoder and put it into operation, please read this manual completely, 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. Keep this manual safely so that you can solve problems in the future.
LD-G-43 tams elektronik Connection to an AC motor a load control adapter LRA (item no. 70-02105 or 70-02106) or a permanent magnet (e.g. no. 70-04100, 70-04200 or 70-04300) or a motor modification set (e.g. no.
tams elektronik LD-G-43 1.3. Intended use The locomotive decoder LD-G-43 is designed to be operated according to the instructions in this manual in model building, especially in digital model railroad layouts. Any other use is inappropriate and invalidates any guarantees. The locomotive decoder should not be mounted by children under the age of 14. Reading, understanding and following the instructions in this manual are mandatory for the user. 1.4.
LD-G-43 tams elektronik 2. Operation overview 2.1. Digital operation The locomotive decoder is a multiple protocol decoder, that can operate with and automatically recognise both DCC or Motorola formats. DCC Motorola II (MM II) according to NMRA and RCN-standard 127 basic addresses or 10.
tams elektronik LD-G-43 2.2. Analogue mode The locomotive decoder LD-G-43 can also be used in analogue model railway layouts run with an AC or DC speed control. The decoder automatically detects whether an AC or DC speed control is used to power the layout. ! Caution: ni k Old analogue driving transformers (e.g.
LD-G-43 tams elektronik Reaction to an overvoltage pulse In analogue AC systems, interference voltages from the system can be interpreted by the decoder as a changeover pulse for changing the direction of travel. The sensitivity with which the decoder reacts to an overvoltage pulse with a change of driving direction can be set in a CV. 2.3.
tams elektronik LD-G-43 2.4. Motor control Pulse width modulation The LD-G-43 is designed to optimally control DC motors. With a PWM of 25 kHz, it is also suitable for coreless motors. Load control The LD-G-43 has a load control. The load control influences the motor voltage to keep the locomotive with a set speed level at constant velocity, independent of additional loads (e.g. running up a gradient, coupled carriages).
LD-G-43 tams elektronik a: Linear characteristic from start and maximum voltage a: Linear characteristic from start and maximum voltage b: Linear characteristic from start, medium and maximum voltage c: Shunting gear = 50 % of the voltage defined in the standard characteristic curve d: alternative characteristic with individual assignment of voltage to the 28 speed levels ni Starting kick (from software version 1.
tams elektronik LD-G-43 Acceleration and brake delay A well adjusted acceleration and brake delay (acceleration and brake rate) achieves a prototypical, jerk-free acceleration and braking of the locomotive. For this purpose, in the CVs is set separately for starting and braking, how much time should pass before the decoder changes to the next higher or lower speed level. The decoder then changes the speed level successively until the set speed level is reached.
LD-G-43 tams elektronik 2.5. Automated processes The control software in the locomotive decoder enables the automation of processes and the combination of complex processes in one function. The processes can thus be activated with a function / a function key. 2.5.1.
tams elektronik LD-G-43 For technical reasons, the track voltage applied to the output of some boosters is not 100 % symmetrical. Some types of additional circuits that are connected to the track (e.g. track occupancy detectors) also influence the track voltage on a rail. To prevent the locomotive decoder from interpreting even a slightly unbalanced track voltage as an ABC braking section, the sensitivity can be reduced.
LD-G-43 tams elektronik 2.5.3. Automatic uncoupling ("uncoupling waltz") By programming the CV accordingly, the complete uncoupling process can be triggered with one function. After switching on the function, the locomotive first moves a little bit against the set direction of travel in order to relieve the coupling. Then the function output to which the coupling is connected is switched on for the set time.
tams elektronik LD-G-43 2.6. Outputs and interfaces Function outputs The decoder has eight function outputs (F0f, F0r, AUX1 to AUX6) with a maximum current of 300 mA each for the connection of additional accessories (e.g. lighting, smoke generator, electrical coupling). Note: The maximum total current of the decoder (including motor) is 1,500 mA. Function mapping according to RCN-227 Assigning the functions to the outputs follows RailCommunity standard RCN-227.
LD-G-43 tams elektronik Effects of the function outputs Successive dimming up and down: The voltage at the output is gradually increased when switched on or gradually reduced when switched off. Assignment separately for each output. Setting the time duration for dimming up and down together for all outputs to which the function is assigned. CV programming CV 55...62 CV 100 Application example: Simulation of old oil or incandescent lamps.
tams elektronik LD-G-43 Output for buffer circuit A special output is provided for the connection of a buffer circuit according to RCN-530 (e.g. UPS-mini). Alternatively, it can be used to connect another consumer with a maximum current of 100 mA. By default, the output is switched on after a short waiting time after switching on the decoder in order to load the buffer. The length of the waiting time varies randomly.
LD-G-43 tams elektronik 2.8. Feedback with RailCom RailCom transmitter The locomotive decoder LD-G-43 is a RailCom transmitter and fulfils the requirements of the RailCommunity standard RCN-217 "RailCom DCC feedback protocol" for mobile decoders (vehicle decoders). Sending RailCom messages is possible in layouts with a DCC signal on the rails only. It is not possible to use the RailCom-function in a pure Motorola environment.
tams elektronik LD-G-43 Transfer of decoder parameters in the DCC-A registration procedure The registration of the decoder with the central unit takes place automatically as soon as the vehicle is placed on the track. Some of the parameters can be adjusted individually with the help of the central unit. Adjustments Principle symbol and symbol e.g.: The decoder can be assigned a principle symbol and a symbol from the file stored in the central unit.
LD-G-43 tams elektronik 3. Connections 3.1. Safety instructions ! Caution: Integrated circuits (ICs) are inserted on the decoder. They are sensitive to static electricity. Do not touch components without first discharging yourself. Touching a radiator or other grounded metal part will discharge you. Mechanical hazards Cut wires can have sharp ends and can cause serious injuries. Watch out for sharp edges when you pick up the PCB. ni k Visibly damaged parts can cause unpredictable danger.
tams elektronik LD-G-43 Thermal danger A hot soldering iron or liquid solder accidentally touching your skin can cause skin burns. As a precaution: 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-43 tams elektronik After soldering, check (preferably with a magnifying glass) whether connections or tracks have been bridged with solder by mistake. This can lead to malfunction or destruction of components or, in the worst case, the complete circuit. You can re-liquefy excess solder with the clean hot soldering tip. The solder then flows from the board onto the soldering tip. 3.3.

tams elektronik LD-G-43 3.7. Use of the LD-G-43 in locomotives with AC motor The LD-G-43 has been designed to control direct current (DC) motors, for that reason it cannot be connected directly to alternating current (AC) motors. You can control AC motors with the LD-G-43 and benefit of the load control when mounting a load control adapter (e.g. item number 70-02105 or 70-02106) between AC motor and decoder or replacing the field coil of the AC motor by a permanent magnet (e.g.
LD-G-43 tams elektronik Connecting accessories to the outputs ! Caution: The maximum current of the accessory must not exceed the maximum current of the output to which you connect it. The output may otherwise be irreparably damaged! 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.
tams elektronik LD-G-43 3.9. 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 (RC). ! Caution: You must always operate LEDs via a series resistor! Otherwise LEDs will be destroyed when put into operation or have a significantly reduced duration of life.
LD-G-43 tams elektronik Parallel connection of LEDs Alternatively, you can connect several LEDs in parallel, each via a series resistor of its own. The current consumption is max. 20 mA for all LEDs, depending on the series resistor´s value.
tams elektronik LD-G-43 3.10. Connecting inductive loads 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 prevent damage at the output. Check to connect the anode of the diode to the function output.
LD-G-43 tams elektronik ni k Connection of reed contacts to the switching inputs Connection of Hall sensors tro Pay attention to the correct polarity when connecting Hall sensors.
tams elektronik LD-G-43 3.12. Connecting a backup capacitor or buffer circuit In sections with bad contact to the rails (e.g. when running over turnouts) or with a (e.g. construction-related) bad current consumption of the locomotive, the power supply of the decoder can be interrupted briefly. In analogue mode the effects are usually small, but in digital mode massive disturbances can be the result: e.g. flickering of the lights and stuttering of the motor up to automatic switching to analogue mode.
LD-G-43 tams elektronik 3.13. Connection of a SUSI module Background information: SUSI interface The SUSI interface is an interface for connecting extension modules (e.g. sound modules, function modules) to vehicle decoders. The characteristic values are defined in the RailCommunity standard RCN-600.
tams elektronik LD-G-43 4.2. Programming with Motorola central units In Motorola format the settings are saved in registers. The registers have the same numbers as the configuration variables (CVs) for the DCC format. Please note: If you use a central unit for both DCC and Motorola format it is recommended to program the decoder in the DCC format. After having finished programming the decoder it is possible to control it in Motorola format as well.
LD-G-43 tams elektronik 5. Configuration variables and registers The following lists shows all configuration variables (for the DCC format) and registers (for the Motorola format), that can be set for the locomotive decoder. Registers and configuration variables (CVs) have identical numbers, they are shown in the tables in the column "No.". The defaults are those values set in the state of delivery and after a reset.

LD-G-43 tams elektronik 5.4. Setting the motor control Optimisation of the driving characteristics By adjusting the load control and the motor characteristics curve the decoder is adapted to the individual characteristics of the locomotive motor. Please note: The installation of a decoder generally increases the effects of vehicle defects on driving characteristics. Locomotive motor, brushes and collector, gearbox, moving parts and current collectors must therefore be in perfect condition.
tams elektronik LD-G-43 Proceed as follows to set the load control parameters: If the locomotive is shuttering: Increase the value for CV 115 (KD) in steps of 2. If this does not lead to an improvement of the driving characteristics, set the value of CV 115 back to factory setting (default value). Then decrease the value for CV 113 (KP) in steps of 2 and for CV 114 (KI) in steps of 1. If the locomotive does not have enough power and e.g.
