2. 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.

Visibly damaged parts can cause unpredictable danger. Do not use damaged parts: recycle and replace them with new ones.

Page 8

Locomotive decoders of the series 30 plus English

Electrical hazards

 Touching powered, live components,  touching conducting components which are live due to malfunction,  short circuits and connecting the circuit to another voltage than

specified,

 impermissibly high humidity and condensation build up

can cause serious injury due to electrical shock. Take the following precautions to prevent this danger:

 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.  After condensation build up, allow a minimum of 2 hours for

dispersion.

 Use only original spare parts if you have to repair the kit or the

ready-built module.

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.

Page 9

English Locomotive decoders of the series 30 plus

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.

Dangerous environments

A working area that is too small or cramped is unsuitable and can cause accidents, fires and injury. Prevent this by working in a clean, dry room with enough freedom of movement.

Other dangers

Children can cause any of the accidents mentioned above because they are inattentive and not responsible enough. Children under the age of 14 should not be allowed to work with this kit or the ready-built module.

Caution:

Little children can swallow small components with sharp edges, with fatal results! Do not allow components to reach small children.

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.

Page 10

Locomotive decoders of the series 30 plus English

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.  When soldering electronic circuits never use soldering-water or

soldering grease. They contain acids that can corrode components and copper tracks.

 Solder quickly: holding the iron on the joints longer than necessary can

destroy components and can damage copper tracks or soldering eyes.

 Apply the soldering tip to the soldering spot in such a way that the

wire and the soldering eye are heated at the same time. Simultaneously add solder (not too much). As soon as the solder becomes liquid take it away. Hold the soldering tip at the spot for a few seconds so that the solder flows into the joint, then remove the soldering iron.

 The joint should be held still for about 5 seconds after soldering.  To make a good soldering joint you should 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.

 After soldering check (preferably with a magnifying glass) tracks for

accidental solder bridges and short circuits. This would cause faulty operation or, in the worst case, permanent 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

4.1. Modes of operation

Digital operation

The locomotive decoder is a multiple protocol decoder, that can operate with and automatically recognise both DCC or Motorola formats.

The number of addresses is dependant on the format being used:

 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). In the Motorola format the decoder can be driven in 14 or 27 speed levels. Driving all 27 speed levels can be done only with central units which support this mode (e.g. MasterControl). With central units which allow 14 speed levels only, it is only possible to select every second speed level.

Programming the decoders is done:

 in Motorola format by setting the registers,  in DCC format by setting the configuration variables (direct

programming, DCC conform) or by POM (programming on main = main track programming). Note: The configuration variables reserved for the SUSI interface ## 897 – 1024 cannot be programmed by POM.

Page 12

Locomotive decoders of the series 30 plus English

Analogue mode

The locomotive decoder can also be used in analogue model railway layouts run with a D.C. or 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.

Caution:

Old analogue driving transformers (e.g. models in a blue housing from Märklin**) are not suitable for use with digital decoders in analogue operation! These transformers have been designed for the older supply voltage of 220 V and, due to construction, generate very high excess voltage impulses when changing the driving direction. When using them with the modern supply voltage of 230 V too high excess voltage impulses can occur, damaging electronic parts on the decoder. For that reason only use driving transformers designed for a net voltage of 230 V.

Switching the function outputs on or off is not possible in analogue mode. They can be programmed so that they are either switched on or off in analogue mode. The effects set for the outputs are active in analogue mode as well.

Outputs to be switched with F0 are switched on or off in analogue mode according to the direction of travel. When operated in analogue d.c. layouts this applies only to lamps or accessories where the return conductor is connected to the decoder´s common return conductor for all function outputs.

The decoders´ load control is also active in analogue mode. The set maximum speed also limits in analogue mode the maximum speed of the locomotive.

Page 13

English Locomotive decoders of the series 30 plus

4.2. Driving of the motor

Pulse width modulation

The pulse width modulation (PWM) of the locomotive decoder can be set to a value between 60 Hz and 30 kHz. This enables you to adjust the decoder individually to the different motor types, including coreless motors.

Load control

The decoder 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).

It is possible to switch on and off the load control by varying a CVvariable of the decoder. The parameters of the load control may be altered, in order to adapt the decoder to the motor´s individual characteristics.

Parameters of the load control: The load control is determined by three parameters which have to be coordinated in order to achieve optimal driving characteristics. Each of the load control parameters is assigned to a configuration variable. The parameters are:

KP: The proportional component of the load control ensures the difference between the set and the present value being as small as possible. It cannot have the value "0" at any time. This component affects the basic speed. In case the set value is too small the locomotive runs too slowly. In case the set value is too high the locomotive stutters while moving.

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.

Page 14

Locomotive decoders of the series 30 plus English

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. If the set value is too high, the locomotive rocks while moving.

Velocity characteristic

The decoder can be adjusted to the driving characteristics of the motor and the characteristic speed of the locomotive type, by setting the starting, medium and maximum velocity. From these three settings the decoder generates a (where required turned) linear velocity characteristic.

When the speed level mode is set to 28 speed levels, it is possible to assign any motor voltage to all of the 28 speed levels as an alternative to the linear velocity characteristic. This allows the programming of a velocity characteristic which adjusts the individual driving characteristics of the motor. The set values are saved in the alternative velocity table.

Shunting gear

It is possible to switch into the shunting gear mode via a function key (in state of delivery F3), when so programmed. In the shunting gear mode, the velocity of all speed levels is reduced to approx. 50 % compared to the set velocity.

Acceleration and brake delay

It is possible to program the acceleration and brake delay individually via the central unit. When so programmed, it can be switched on and off with a function key (in state of delivery F4).

Page 15

English Locomotive decoders of the series 30 plus

4.3. Function outputs

The decoder has function outputs, which are available to connect optional accessories (e.g. lighting, smoke generator, sound module, electric coupling). The accessories´ number and type to be connected depends on the outputs´number and maximum current as well as on the maximum total current of the special decoder (see section 5 "Technical specifications").

Effects of the function outputs

It is possible to set the following effects for the function outputs (except AUX7) individually:

 Switching on and off depending on the direction of travel.  Flashing and double flashing. Both the frequency and the keying

ratio can be set. E.g. single and double flash lights or strobe lights.

 Kick function: It is possible to set the amplified function outputs so

that they get the full voltage first for up to 12,5 seconds and then are switched off. Example of use: For some types of electric couplings you need the full voltage for decoupling and the voltage then switched off to protect the couplings.

 Shunting light: You can program the outputs so that they are

switched on generally during shunting operation (to be switched with F3 or F4). The dependence on the direction of travel will be nullified for these outputs during shunting operation.

 Special function for speed level 0: It is possible to program one

function to switch off other functions or switch on special function outputs at speed level 0. Example of use: In some locomotive sheds it is customary that the tail lamps of parked locomotives have to be temporally set at the front and the back.

 Dimming: Example of use: The electric bulbs of older vehicles made

for analogue operation can be dimmed and thus must not be exchanged after the mounting of the decoder.

Page 16

Locomotive decoders of the series 30 plus English

 Dimming depending on the speed level: The voltage will be dimmed

depending on the speed level. This enables weak smoke generation during halts or a switched off or dimmed cab lighting while the train is moving.

 MARslight (= light intensity going up and down): Example of use:

american locomotives with this type of lighting.

Servo output (except LD-G-31 plus) The decoders LD-G-33 plus, LD-G-34 plus and LD-G-36 plus have an

output sending the signals to control a servo. The voltage supply for the servo cannot be provided by the decoder. For that reason an external voltage supply (e.g. servo PCB item-no. 70-05900) is required.

The servo is controlled by:

 setting the end positions via CVs and controlling by pushing the

function keys ("on" = end position 1 , "off" = end position 2) or

 input of a value for the folding square by POM, which allows to

approach to any folding square.

4.4. Sound functions

SUSI interface (except LD-G-31 plus) A SUSI module can be connected to the locomotive decoders LD-G-33

plus, LD-G-34 plus and LD-G-36 plus and read out, programmed and controlled via the decoder.

The decoder transmits the function status and the speed level set at the central unit, to the SUSI module. This affects the SUSI module´s outputs depending on the speed level (e.g. motor sound). The decoder allows the setting of the acceleration and braking delay so that the functions depending on the speed level correspond to the driving characteristics during accelerating and braking.

Page 17

English Locomotive decoders of the series 30 plus

Integrated sounds (except LD-G-36 plus) The locomotive decoders LD-G-31 plus, LD-G-33 plus and LD-G-34 plus

have three integrated sounds:

 locomotive whistle,  bell,  signal horn.

Driving sound (LD-G-36 plus only) You can trigger different sounds via the digital control unit´s function

keys (standing and driving sound, signal horn or locomotive whistle, decoupling or door closing sound, bell or second signal horn). The function keys can be assigned freely to the sounds.

Four sounds typical for a locomotive type are saved on an IC in the decoder. They are recordings of original sounds of the vehicle examples. Before delivery the module is programmed with sounds from a sound data base. Using a special programming device (Tams sound programmer, item no. 70-03200) allows to alter the decoder´s programming.

A clock generator (e.g. Hall sensor or reed contact in combination with a magnet) allows to control for example the correct synchronising of the steam discharge with wheel movement.

Possible settings The settings in state of delivery can be adjusted by changing the

configuration variables:

 volume;  steam discharge of steam locomotives;  length of the breaks between signal sounds;  release thresholds at change of motor load, for breaking sound and

for ventilator sound of electric locomotives;

 fading time (= period of time of fading in and down when switching

on and off);

Page 18

Locomotive decoders of the series 30 plus English

 sensitivity to load changes;  time of no-load running;  assignment of the sounds to the function keys.

4.5. Releasing the functions

The function outputs, the servo output, the integrated sounds and with the LD-G-36 plus the driving sounds can be released by:

 pushing the function keys and / or  automatically via the two switching inputs. The switching inputs are

released via external contacts, e.g. via reed contacts or Hall sensors in combination with permanent magnets in the rails.

Hint for locomotive decoder LD-G-33 plus: When there is connected a SUSI module, the switching inputs are not available.

Hint for locomotive decoders LD-G-34 plus and LD-G-36 plus: The sounds of a connected SUSI module can be triggered by the function keys as well as by the switching inputs that are assigned to these function keys. .

Mapping of the outputs to 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.

Output DCC format MM format F0f / F0r F0 to F12 F0 to F4 or

F5 to F9

(= F0 to F4 of a second decoder address)

AUX1 to AUX6

(LD-G-31 plus: AUX1 to AUX2)

F0 to F28

AUX7 (versions with connections

according to PluX only, except LD-G-31 plus)

F13 to F28

All function outputs can be switched inverted, i.e. when set to position "on" the assigned function output will be switched off, when set to position "off" switched on.

Page 19

English Locomotive decoders of the series 30 plus

4.6. Automated processes

The control software in the locomotive decoder allows you to automate procedures and to reduce complex processes to one keystroke.

Automatic commuting operation

It is possible to install an automatic commuting operation between two terminal stations, via the switching inputs. You can assign a function key to the automatic commuting operation, in order to switch it on or off during operation.

Sequence: As soon as the switching input has been released (e.g. by a magnet in the track in combination with a Hall sensor or a reed contact), the locomotive breaks with the set brake delay. After the set stop time the locomotive starts with the set acceleration delay. Depending on the settings, the direction of motion is altered internally and the locomotive runs back into the opposite direction or goes on in the same direction.

When so programmed, closing one of the switching inputs on the main track between the terminal stations will be ignored by the commuting automatic and can be used to trigger any function during commuting operation. Please note, that always all active functions assigned to the switching input are released as soon as the switching input is closed. The second switching input can be used to release additional stops on the commuting line.

Possible settings for CV programming:

 length of the stop time (0 to max. 160 seconds), either commonly

for both directions or separately for advancing and reversing;

 whether a change of direction has to be performed after a stop;  switching off the commuting automatic with function key F5 to F12;  number of switching impulses between two terminal stations to be

igrnored (and not releasing the braking for terminal station).

Page 20

Locomotive decoders of the series 30 plus English

Dimming depending on the velocity

You can automatically switch functions depending on the velocity when reaching a speed level defined in a CV. You assign an individual voltage to the function outputs for the ranges of speed levels underneath and above the defined speed level. This allows for example to switch on and off the high beam light, to control the cab light or to influence the intensity of the steam output.

Shunting function

You can assign the shunting gear and the shunting light to the same funtion key. That way you switch on the shunting light automatically when switching into the shunting gear (and thus reducing the velocity).

Special function for speed level 0

By programming the special function for speed level 0 you can switch on or off several function outputs and functions at the same time, you otherwise had to switch singularly. This allows e.g. to switch off several lights at once when parking a locomotive in the depot (e.g. front and back lights, cab light and undercarriage light).

Automatic coupling and decoupling

With an appropriate CV-programming you can release coupling and decoupling operations automatically with one function key. In order to use the automatic coupling function you have to assign one function key to each of the directions "forward" and "backward". In order to couple the locomotive drives with the velocity set in a CV against the carriage to be coupled. As soon as the assigned switching input has been connected to earth (e.g. via a current transmitting coupling), the locomotive stops. After having coupled, the primary driving direction is set again.

For decoupling the locomotive first runs a small distance against the set driving direction, in order to relieve the coupling. The function output connected to the coupling is switched on. In order to prevent the

Page 21

English Locomotive decoders of the series 30 plus

coupling from damage, the current is switched off automatically after the set time. The driving direction is changed over to the set direction of motion and the locomotive drives away a small distance from the decoupled carriage.

4.7. Feedback with RailCom and RailCom plus

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.

When so programmed, the locomotive decoders of the series 30 plus send (continuously) the (basic, extended or consist) address to the detectors (socalled RailCom broadcast datagramm) and transfer a CV message after a DCC CV read-out command.

Sending RailCom messages is only possible in layouts with a DCC signal on the rails. It is not possible to use the RailCom-function in a pure Motorola environment.

RailComPlus enables the decoder to log in automatically at the digital control unit. In doing so the locomotive address and name as well as the functional mode and range are transmitted. The precondition for using RailComPlus is using a control unit providing this type of feedback.

Page 22

Locomotive decoders of the series 30 plus English

4.8. Overload protection (except LD-G-31 plus)

The locomotive decoders LD-G-33 plus, LD-G-34 plus and LD-G-36 plus have an overload protection, which prevents them from overheating when exceeding the maximum motor or total current.

As soon as the maximum motor or total current is exceeded, the decoder automatically temporarily switches off. This operation will be repeated until the overload has been eliminated.

When exceeding the maximum current at the output only (but not the total current of the decoder) the decoder´s overload protection is without effect, the concerned output will be damaged.

Attention:

When a short circuit occurs that bypasses components on the decoder either to each other or to track voltage, the overload protection is not effective. Examples:

 contact between the decoder and the rails or metal parts of the

vehicle;

 contact between not-isolated decoder connecting wires and the rails

or metal parts of the vehicle;

 contact between accessories connected to the common return

conductor of the decoder and the rails or metal parts of the vehicle.

Attention:

Malfunctions of the locomotive motor (e.g. the so-called "sparking of the brushes") can cause extreme interference current, possibly damaging components on the decoder. The decoder´s overload protection is without effect with this extremely high current.

4.9. POM-update (except LD-G-36 plus)

POM-update is a procedure allowing to update the decoder´s firmware (= specific decoder software) without dismounting the decoder or using a specific device. POM-update is based upon programming on main (POM) for the DCC format.

Preconditions for using the procedure are:

 Locomotive decoder LD-G-31 plus from version 2.4,

locomotive decoder LD-G-33 plus from version 2.5 or locomotive decoder LD-G-34 plus from version 2.5.

 Digital central unit with PC interface providing the DCC format and

POM. Hint: As nearly every manufacturer of central units uses his own procedure for programming on main, the POM-update can be performed with the following central units only (status 01/2015):

MasterControl (Tams Elektronik) Intellibox 1 (Uhlenbrock**) CS2 (Maerklin**)

The current list of central units allowing to perform the POM-update is available on our homepage.

 PC. The system software must support Java.  Software "POM-Updater.exe": You will find it on the CD included in

delivery. It is also available on our homepage for free download.

You can download the current firmware version of the decoder free of charge from our homepage. If you want to get information on new firmware versions please subsribe to our newsletter on our hompage.

6. Connections

Note the following comment in order to protect the decoder from (maybe irreparable) damage!

Avoid all conducting connections between the decoder and accessories connected to the decoder´s common return conductor for all function outputs on the one hand and metal parts of the vehicle or the rails on the other hand. Connections result for example from badly isolated connecting wires (as well at the stripped ends of connecting wires not in use) or insufficient fixing and isolating the decoder or the accessory, for example. Risk of short circuit! In this case the overload protection of the decoder is not able to protect the decoder from damage.

Before connecting the motor, lighting or other accessories check if the current is below the maximum permissible values and the total current is below the safe load. Should the permissible current be exceeded, this can result in damage to the decoder. Exceeding the motor current or the permissible total current of decoders with overload protection, will lead to switching off the decoder.

You should under no circumstances connect the decoder´s common return conductor for all function outputs to vehicle ground. Risk of short circuit!

6.7. Using decoders with interface connectors

Many recent locomotives with d.c. motor are equipped ex works with an interface socket or an interface plug. Using a decoder with a suitable connector saves separating the connections and soldering works at the locomotive. Possible versions:

Description Number of poles MOROP standard 8 pole 8 NEM 652

PluX12,-16,-22

(Fig.: PluX12)

11, 15 oder 21 NEM 658

21MTC 21 NEM 660

(2 boosted outputs)

21 pole (similar to 21MTC)

21-pole 21 ---

(4 boosted outputs)

The interface enables you to connect the decoder to the motor, the rail current collectors, the lighting and – provided the special connector is designed for it – additional accessories.

When mounting decoders with 6-pole interface connectors according to NEM 651 or 8-pole interface connectors according to NEM 652, take care to put the markings on the connector and on the socket on top of each other. The PluX-connectors according to NEM 658 and 21MTC

-connectors according to NEM 660 can be mounted in one direction only.

You can use a decoder with PluX12 interface connector in a locomotive with PluX16 or PluX22 interface as well. All functions provided by the decoder are available then.

Page 42

Locomotive decoders of the series 30 plus English

Hint:

There are locomotives available that have interfaces physically going up to the 21MTC interface, but not having 2 boosted outputs (corresponding to NEM 660) but 4 boosted outputs. Only locomotives made corresponding to NEM 660 are allowed to be labelled with the 21MTC logo. Please check on the package and in the manual of your locomotive whether the interface corresponds to NEM 660 or not and use the suitable decoder version.

6.8. Use in locomotives with a.c. motor

The locomotive decoders of the series 30 plus have been designed to control direct current (d.c.) motors, for that reason they cannot be connected directly to alternating current (a.c.) motors. You can control a.c. motors with the locomotive decoders of the series 30 plus and benefit of the load control when

 mounting a load control adapter between a.c. motor and decoder or  replacing the field coil of the a.c. motor by a permanent magnet.

Page 43

English Locomotive decoders of the series 30 plus

6.9. INFO: Earth connections and voltage outputs

Most locomotive decoders of the series 30 plus have several earth connections (-) as well as voltage outputs (+). In the connection lists the connections for the return conductors of the accessories, for the servos, reed contacts and Hall sensors and the buffer capacitors are specified as they are most practicable for usual assignment. You can choose another assignment of the earth connections (-) and the voltage outputs if necessary.

Possible assignments to earth connections (-)

Hint: You need an external supply voltage for the servos!

Page 44

Locomotive decoders of the series 30 plus English

6.10. Mounting decoders without interface

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.

Caution:

The interference suppression devices mounted to the motor or the connecting wire must not be removed! Motor and interference suppression devices are one unit. If even one part is removed, it can cause extreme interference!

Connecting the decoder to the motor

Connect the decoder to the rail current collectors and to the motor. Should the locomotive´s direction of motion in analogue mode not match the direction of motion set at the speed control you have to swap the connections to the rail current collectors / the slider.

Fig. 1: Connection of the motor and the power supply

Page 45

English Locomotive decoders of the series 30 plus

Connecting accessories to the outputs

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. If not, connect the second side of the lamp or the accessory to the decoder´s common return conductor for all function outputs.

You find the factory (default) settings in the lists with the connector pin assignments. You can assign the outputs to the function keys voluntarily by setting the configuration variables.

Fig. 2: Examples for the connection of accessories and LEDs to the function outputs

F0f and F0r: Light forward / backward motion

AUX1: parallel connection of LEDs

AUX3: serial connection of LEDs

AUX4: combined parallel and serial connection of LEDs

Attention: The examples of connection are suitable to only a limited extent for the decoders with 21MTC and 21 pole interface. With the decoders with 21MTC interface AUX3 to AUX6 and with the decoders with 21 pole interface AUX5 and AUX6 have a capacity of only 10 mA!

Page 46

Locomotive decoders of the series 30 plus English

6.11. 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.

Caution:

If you use light-emitting diodes (LEDs) you must always operate them via a series resistor, otherwise they will be damaged when put into operation or their duration of life will be reduced considerably!

When doing without a series resistor, other components undertake the series resistor´s function (e.g. rails, wheels, current connectors), possibly leading to a modification of the data signal and thus to disturbances in digital operation.

Always determine the necessary series resistor´s value for the peak value of the available operating voltage. With regulated boosters this corresponds to the specified boosters´ output (= track) voltage. With not regulated boosters or analogue driving transformers the peak value is approx. 1,4 fold the nominal voltage specified on the transformer.

Serial connection of LEDs

When you want to connect several LEDs to one output you can switch them in series via a common series resistor. The current consumption is max. 20 mA for all LEDs, depending on the series resistor´s value. The maximum number of LEDs to be connected in series results from

Peak value of the operating voltage

- sum of the forward voltages of all LEDs > 0

The advantage of this solution is the low current consumption. In order to determine the necessary series resistor for a serial LED´s

Page 47

English Locomotive decoders of the series 30 plus

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.

The remaining voltage has to be "eliminated" by a resistor. The formula for the calculation of the resistor is:

required RV [Ohm] = ( UB [V] – ∑ UF [V] ) / (IF [mA] x 0.001)

UB = operating voltage (peak value) | ∑ UF = sum of the forward voltages of all LEDs IF = current with max. luminosity

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. The maximum number of LEDs to be connected in parallel results from

maximum current at the output

- sum of the current consumption of all LEDs > 0

Advantageous with this solution is that the LEDs already lighten when their forward voltage has been reached (2 to 4 V, depending on the fluorescent colour), which makes this solution suitable for analogue mode. Disadvantageous is the high current consumption.

The formula for the calculation of the resistor is:

required RV [Ohm] = ( UB [V] – UF [V] / (IF [mA] x 0.001)

UB = operating voltage (peak value) | UF = forward voltage of the LED IF = current with max. luminosity

In order to save current, you can limit the LEDs´current consumption to 10 mA, which normally does not cause a visible loss of luminance.

Page 48

Locomotive decoders of the series 30 plus English

6.12. 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 avoid damage at the output. Check to connect the anode of the diode to the function output.

6.13. Connecting accessories via a relay

When you want to switch an accessory / accessories via the decoder, which connection would lead to exceeding the maximum current at the output or of the decoder, you can switch the accessories via a relay (e.g. 1xUm 1A 12V, item-no. 84-61010) and connect them directly to the vehicle´s current collector.

The current consumed by the relay depends on its type. The relay named in the example needs approx. 100 mA.

As described in the section "Connecting inductive loads" you should switch a free-wheeling diode (e.g. 1N400x) in parallel to the relay.

Fig. 3: Connection of an accessory via a relay

Page 49

English Locomotive decoders of the series 30 plus

6.14. Connecting a loudspeaker

Use a loudspeaker with an impedance of at least 4 Ohm. When connecting a loudspeaker with a lower impedance, the output for the loudspeaker will be damaged. As a rule the playback quality increases with the loudspeaker´s size. For that reason you should choose a loudspeaker as large as possible.

In addition, the correct mounting of the loudspeaker is decisive for the sound reproduction. The loudspeaker membrane should emit directly to the outside, the other side into the inside of the vehicle which should be as airtight as possible. The larger the volume in the inside, the better is the reproduction quality. Suitable for the mounting are e.g. the bottom of the vehicle or the back of the driver´s cab.

Clearing disturbances of the sound reproduction

As a matter of principle the sound playback can be distorted or disturbed by a high whistling noise. In this case you should solder a suppression choke (> 470 µH / 90 mA) into one of the supply wires of the loudspeaker (except with the LD-G-36 plus).

Disturbing noises can occur with a bad current draw (e.g due to dirty rails or at points) and with RailCom switched on. You can remedy these disturbances by mounting a buffer capacitor.

6.15. 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 or disturbing noises from the loudspeaker. In these and similar cases you can find a remedy by connecting a buffer capacitor.

The electrolytic capacitor should have a capacity of minimum 100 µF (LD-G-31 plus) or 220 µF and a proof voltage of minimum 25 V. When used in analogue a.c. layouts, a voltage of minimum 35 V is required. Observe the correct polarity when connecting the capacitor!

Page 50

Fig. 4: Connection of a buffer capacitor to improve the voltage supply and of a suppression choke at the loudspeaker

6.16. Connecting a servo (not with LD-G-31)

Connect the signal input of the servo to servo output and the earth connection of the servo to an earth connection of the decoder. The voltage supply for the servo should not be taken from the decoder, as the decoder cannot supply the current needed to control the servo. For that reason you need an external voltage supply for the servo (e.g. servo PCB item no. 70-05900).

6.17. Connecting the switching inputs

Depending on the decoder type and layout you can connect components to be used to trigger the switching inputs (e.g. reedcontacts or Hall sensors) either directy to the soldering points or via the SUSI interface. With the decoder versions equipped with a SUSI plug (LD-G-33 plus and LD-G-36 plus in the PluX version), you need a SUSI socket with wire for the connection of the switching inputs (e.g. item no. 70-01111).

*5 With the LD-G-33 plus you can either use the switching inputs or connect a SUSI module. With the LD-G-36 plus you can simultaneously use the switching inputs and connect a SUSI module, the SUSI module has to be connected to the appropriate connections of the PluX interface in this case.

The switching inputs switch respective to the decoder ground and thus can be connected to all (external) circuits allowing to make contact to

Page 52

earth. It is possible to connect reed contacts or Hall sensors, for example, which make contact to earth when getting into the magnetic field of a permanent magnet.

You can switch the switching inputs respective to the decoder mass as an alternative. In this case you have to solder a resistor (3,3 kOhm) into the connection between switching input and earth of the rails.

Connect the reed contacts to the switching inputs and an earth connection of the decoder. Reed contacts are not polarized, you can assign the two contacts voluntarily.

When connecting Hall sensors check for the correct polarity. Connect the earth connection of the Hall sensor to an earth connection of the decoder, the connection for the voltage supply to a voltage output of the decoder and the output to one of the switching inputs.

When exchanging the earth connection for the connection of the

voltage supply, the Hall sensor can be damaged!

6.18. Connecting a SUSI module (except LD-G-31 plus)

The SUSI interface is a standardized interface for the connection of accessory modules to a vehicle decoder. Controlling the SUSI module has to be carried out by the vehicle decoder. In order to make the necessary settings for the SUSI module you have to program the decoder.

The decoder (except LD-G-36 plus with 21MTC- or 21-pole interface) has a soldered SUSI-plug, fit to insert the socket of the SUSI module. With the LD-G-36 plus with MTC- or 21-pole interface you can solder a SUSI module on the soldering pads provided for that purpose.

There are connections according to SUSI integrated in the 21MTC-and the PluX22 interface, as well. Only the decoder versions without PluXplug or MTC-socket are suitable for connecting an external SUSI module to these connecting points.

Please note, that with the locomotive decoder LD-G-33 plus you can either connect a SUSI module or use the switching inputs. With the decoders LD-G-34 plus and LD-G-36 plus you can both connect a SUSI module and use the switching inputs.

6.19. Connecting a clock generator to the LD-G-36 plus

You can control for example the correct synchronisation of the steam discharge with the wheel movements. For that purpose connect a reed contact or a Hall sensor as a clock generator and fix two or more mini magnets to the wheels. When connecting a Hall sensor observe the right polarity.

6.20. Fixing the decoder

After having finished all connections you should fix the decoder, to avoid short circuits by contact to metal parts of the vehicle, for example. You can use double sided adhesive tape for it, for example.

7. Programming

Programming with DCC central units

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. With central units that allow only register-programming it is not possible to program the decoder.

Programming with Motorola central units

In Motorola format the settings are saved in registers. 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.

Please note: You should connect a lamp or a LED to at least F0f or F0r before starting to program the decoder with a Motorola central unit, as the decoder shows the status of the programming by flashing the lighting connected to these outputs. The flashing frequency shows, which input the decoder expects:

Slow flashing Fast flashing

Number of the register to be programmed

Value of the register to be programmed

Put the vehicle on a track oval or a track section connected to the central unit’s track output (not to the connection for the programming track). Make sure no other vehicle than the one you intend to program is set on the track as the decoder inside this vehicle might be programmed as well.

1. Switch on the central unit or perform a reset at the central

unit (pushing "stop" and "go"

simultaneously).

2. Set the current decoder

address (default value: 3) or

the address "80".

3 Set all functions to "off".

4. Push button "stop"

à switch off the track voltage.

5. Operate the direction switch

and hold it in that position.

Push the button "go" at once.

6. As soon as the lighting flashes, release the

direction switch.

1. Enter the number of the

If necessary: with a leading "0".

2. Operate the direction switch. à Lighting flashes faster.

3 Enter the value you want to

set into the register

(as Motorola-address).

4. Operate the direction switch.

à Lighting flashes more slowly.

Repeat steps 1 – 4

for all registers.

Push button "stop".

à Programming mode à End of programming mode.

Programming with central units with restricted input options

Some central units do not allow but input values up to 80 or 99. Two auxiliary registers (CV#26 and #30) make it possible to enter higher values.

Programming with the Central Station and the Mobile Station

With the Central Station I or the Mobile Station of Märklin** you can program the registers. Select the article no. 29750 from the locomotive database and program the decoder as described for this article in the Central Station´s or Mobile Station´s manual.

Page 56

Locomotive decoders of the series 30 plus English

Programming with the CV-Navi

Instead of programming the configuration variables or registers of the decoder using the digital central unit, you can use the free software CVNavi. In order to use the software, you need a digital central unit supporting the p50x-protocol (e.g. Tams MasterControl or Intellibox of Uhlenbrock**).

You will find the free download presumably from beginning of 2014 under: www.tams-online.de

8. Configuration variables and registers

In the lists you will find in the column "No." the numbers of the configuration variables for programming in DCC format. The numbers of the registers for programming in Motorola format are identical to the CV numbers. The defaults are those values set in the state of delivery and after a reset.

Please note: With variables destined to set several parameters, the input value has to be calculated by adding the numerical values assigned to the desired parameters.

Tip: It is standard to switch over into analogue mode when applying a d.c. voltage at the rails. In case that the decoder is run in a layout with a braking route based on applying a d.c. voltage (e.g. Märklin**-braking route), the analogue recognition has to be disactivated (in CV#29) to ensure that the locomotive reacts as expected on the braking route.

The setting of the negative or positive d.c. voltage is related to the right rail, as seen in the locomotive´s direction of motion.

Example: CV#65 = 6 à The motor voltage while starting is equivalent to the voltage applied in operation at speed level 6 (of 255). It is reduced immediately to the actually set speed level with the braking rate defined in CV#4. Thus, when altering the value for CV#4 it may be necessary to alter CV#65, too.

Optimising the CV-settings

Above all, the driving characteristics can be influenced by setting the CV#2 (starting voltage), the CV#6 (medium velocity) and CV#5 (maximum voltage).

In addition, you can alter the parameters of the load control. To adjust the parameters for the load control (CV#50 to #52) the following procedure is recommended:

If the locomotive is shuttering: à Increase the value for CV#52 (KD) in 5-steps. If this does not lead to an improvement of the driving characteristics, set the value of CV#52 back to factory setting (default value). Then decrease the value for CV#50 (KP) in 5-steps and for CV#51 (KI) in 2-steps.

If the locomotive does not have enough power and e.g. gets very slow on the way uphill: à Increase the value for CV#51 (KI) in 2-steps, until the locomotive starts to shutter. Then increase the value for CV#52 (KD) in 5-steps. If this does not lead to an improvement or the locomotive starts to shutter immediately after increasing CV#51, set the values for CV#51 and CV#52 back to factory setting (default value) and increase the value for CV#50 (KP) in 5-steps.

If the locomotive is rocking: à Decrease the value for CV#52 in 5steps.

If you are not content with the driving characteristics in slow approach, you can influence them by altering CV#166 and CV#165. Start with altering the value of CV#166 in 1-steps.

Tip: Setting the parameters of the load control is very difficult, a change can result in a considerable worsening of the driving characteristics. For that reason you should always alter the values in small steps only. When altering the parameters of the load control does not result in an improvement, you should reset the default values.

for AUX2 8 for AUX3 16 for AUX4 32 for AUX5 64 for AUX6 128

When setting the extended kick function for an output, the motor is supplied with power as long as the kick function is switched on.

Example of use: When switching an output via the extended kick function the locomotive runs automatically a little bit nearer to the carriage (in order to ease the burden from the coupling). Afterwards the electric coupling is released via the kick function and the locomotive moves away automatically from the uncoupled carriage.

9. Performing a POM-Update

Hint: The POM-Update is possible with decoders from version 2.4 (LD-G-31 plus) or version 2.5 (LD-G-33 plus and LD-G-34 plus). For updating decoders with a former firmware version you have to send them in. The version number is saved in CV #7.

Preparations

1. In order to perform the firmware update you do not have to dismount the decoder. Put the vehicle with the mounted decoder on the main track. Hint: You can perform a firmware update with several locomotive decoders of the same type at once, the current software version of the decoders is of no importance. The individual CV settings of the decoder will not be altered by updating.

2. Save the file with the newest firmware on your PC, e.g. LD-G-31_plus_V2_5_0_0.hex for version 2.5.0.0 You can download the newest firmware from our homepage

without charge. When getting (on the part of any third parties) a packed file (e.g. *.zip) you have to unpack it first.

3. Get ready the CD with the program "POM-Updater.exe" (included in the delivery) or download the program from our homepage.

4. Connect your central unit with the PC. At present (status: 01/2015) the POM-Update can be carried out with the MasterControl (Tams Elektronik), the Intellibox 1 (Uhlenbrock**) and the CS2 (Maerklin**) ). You find the current list of central units allowing to perform the POM-update on our homepage.

5. Before starting the update connect at least one lamp or LED to F0f as the update´s status is shown by lighting or flashing of the lighting connected to this output.

Page 81

English Locomotive decoders of the series 30 plus

Changing into the update mode

Execute the programm POM-update.exe, follow the helpfile. Proceed as follows:

1. Make the settings for the update.

2. Enter the addresses of the locomotive decoders you want to update.

3. Change into the update mode.

The lighting connected to the outputs F0f of the decoders which are chosen for an update start to flash slowly. If flashing quickly, the decoder cannot be updated

 because the decoder type does not correspond to the hex-file or  because the decoder´s firmware already conforms to the version of

the hex-file.

The concerned vehicles can stay on the track, they do not affect updating the other decoders. As an alternative you can cut them from current shortly in order to stop them flashing quickly.

Performing the POM-Update

After having changed into the update mode you can start the update. The lighting connected to the outputs F0f of the decoders in update mode stop to flash and show permanent lighting.

The duration of the update depends on the central unit in use and the extent of the transferred data. The progress is shown in the screen mask. As soon as the update has been finished the lighting start to flash slowly. Cut the vehicles from current shortly. Now the vehicles are in standard operation again.

When a fault occurs during updating, the update is interrupted and the lighting starts to flash quickly. In this case restart the update after altering the settings if necessary (see helpfile of the programm for further information).

10. Check list for troubleshooting

 Parts are getting very hot and/or start to smoke.

Disconnect the system from the mains immediately!

Possible cause: one or more connections are soldered incorrectly. à Check the connections.

Possible cause: Short circuit between the decoder or accessories connected to the return conductor for all functions and metal parts of the locomotive or the rails. à Check the connections. A short circuit can result in irreparable damage.

Problems with the driving characteristics

 After programming the decoder the locomotive does not run or runs

badly. Possible cause: The set values for the CV are inconsistent.

à Perform a decoder reset and program the decoder anew.

 In digital mode the locomotive suddenly runs very fast.

Possible cause: Interfering signals from the layout have switched the decoder to analogue mode. à As the origin of the interfering signals´ often cannot be found, it is advisable to switch off the automatic recognition of the analogue mode during digital operation. As an alternative you can increase the value for CV#11.

 The CV values cannot be read out by RailCom.

Possible cause: RailCom is switched off. à Alter the value of CV#29 (add "8" to the input value).

 The decoder switches off in operation, switches on after a short time

and switches off again immediately. Possible cause: The overload protection was activated, as the current

consumption exceeds the decoder´s maximum total current. à Check the current consumption of the motor and the accessories. Possibly the decoder is not suitable for being mounted in this locomotive.

Page 83

English Locomotive decoders of the series 30 plus

Problems in analogue mode

 The locomotive does not run in analogue mode, the decoder does

not work. Possible cause: The analogue mode is switched off.  Alter the

value for CV#29.

 The decoder does not switch to analogue mode (or switches over

although it is still digitally controlled). Possible cause: The value in CV#11 is set too high or too low.

 Alter the value and check the settings in operation.

Problems with switching of the functions

 An accessory / a light does not react to switching commands.

Possible cause: The accessory is defective or incorrectly connected.  Check the accessory / the connections.

Possible cause: The output is defective (e.g. due to overload or short circuit).  Send in the decoder for check / repair (with costs).

 The lighting goes on and off when the speed levels are turned up or

the lighting cannot be switched on or off. Possible cause: The speed mode of the decoder and the digital control

unit do not correspond. Example: The central is set to the mode 28 speed levels, but the decoder to the mode 14 speed levels.  Change the speed mode at the central and / or at the decoder.

Problems with switching via switching inputs

 After passing a permanent magnet in the rails no function is

activated. Possible cause: The reed contact or the Hall sensor has been

mounted incorrectly.  Check the connections. Possible cause: The distance to the magnet is too large or the

magnet is too weak.  Alter the position of the magnet (if possible) or use a stronger one.

Page 84

Locomotive decoders of the series 30 plus English

Possible cause: The magnet has been mounted incorrectly polarized.  Alter the mounting direction.

Possible cause: The function has been assigned incorrectly to the switching input.  Check the settings in CV## 61 to 64 and 177 and

178.

Problems with the sound playback

 There is no sound to be heard after switching on.

Possible cause: The loadspeaker has been connected incorrectly.  Check the connections.

Possible cause (LD-G-36 plus only): The sound level has been set too low in CV#902.  Check the settings.

Possible cause: The decoder is incorrectly connected to the SUSI interface of the sound module.  Check the connections.

 The sound playback is bad, the loudspeaker hums, you can hear

disturbing noises.  Mount a buffer capacitor and a suppression choke.

Problems with switching the servo

 The servo does not move.

Possible cause: The left and the right stop are defined incorrectly.  Check the settings in CV##169 and 170.

Possible cause: The servo has been mounted incorrectly.  Check the connections.

Possible cause: The power supply is connected incorrectly  Check the connections.

Problems with the POM-Update

 While updating the decoder the lighting starts to flash, the update is

interrupted. Possible cause: The settints for the POM-Update are wrong.

à Check and alter the settings if necessary. The helpfile contains explanations.
