1. Getting started
How to use this manual
This manual gives step-by-step instructions for safe and correct fitting
of the decoder, 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. If
you pass the decoder on to another person, please pass on the manual
with it.
Intended use
The locomotive decoder is designed for mounting in a model train with
DC motor (LD-G-33) resp. AC motor (LD-W-33). It evaluates the
Motorola or DCC format data sent by the digital central unit to its
address and controls the locomotive´s motor and additional functions.
The 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.
Any other use is inappropriate and invalidates any guarantees.
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.
Page 4
LD-G-33 / LD-W-33 English
Checking the package contents
Check the contents of the package for completeness after unpacking:
§ one decoder, with or without soldered connecting wires resp.
soldered NEM 652 interface connector, depending on the version,
§ one electrolytic capacitor 100 µF / 35 V,
§ one manual.
N.B. For technical reasons it is possible that the PCB is not completely
inserted. This is not a fault.
Required tools and materials
Make sure you have the following tools and materials ready for use:
§ an electronic soldering iron (max. 30 Watt) with a fine tip,
§ a soldering iron stand,
§ a tip-cleaning sponge,
§ a heat-resistant mat,
§ a small side cutter, a wire stripper and a pair of tweezers,
§ tin solder (0,5 mm. diameter),
§ wire (diameter: > 0,05 mm² for all connections).
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.
Electrical hazards
§ Touching powered, live components,
§ touching conducting components which are live due to malfunction,
§ short circuits,
Page 5
English LD-G-33 / LD-W-33
§ connecting the circuit to another voltage than specified,
§ impermissibly high humidity,
§ 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 decoder.
§ Mounting the decoder should only be done in closed, clean, dry
rooms. Beware of humidity.
§ Only use low power for this decoder 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 decoder.
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. 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.
Page 6
LD-G-33 / LD-W-33 English
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 decoder.
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, mounting
and operation must be supervised by qualified personnel.
In industrial institutions, health and safety regulations applying to
electronic work must be adhered to.
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.
Page 7
English LD-G-33 / LD-W-33
§ 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
Driving in digital operation
The locomotive decoder is a multiple protocol decoder, that can operate
with and automatically recognises 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 decoder is done in DCC format by setting the
configuration variables and in Motorola format through the registers.
Page 8
LD-G-33 / LD-W-33 English
Operation in analogue mode
The locomotive decoder LD-G-33 or LD-W-33 can also be used in
analogue model railway layouts. It can be run with an A.C. speed control
as well as with a D.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.
The load control of the LD-G-33 is is also active in analogue mode. The
set maximum speeds also limits in analogue mode the maximum speed
of the locomotive.
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.
Short circuit protection
As soon as the decoder´s maximum total current (1.500 mA) is
exceeded, the decoder automatically temporally switches off the motor
and the function. This operation will be repeated until the short circuit
has been eliminated.
Driving of the motor
Both decoder types LD-G-33 and LD-W-33 are designed to optimally
control their particular motor types.
The locomotive decoder LD-G-33 drives the (D.C.) motor with either a
PWM of 17 or 32 kHz. This guarantees a soft and constant run of the
motor, with which the decoder can also be used with coreless
(Faulhaber) motors.
The locomotive decoder LD-W-33 drives the (A.C.) motor with a PWM
of 480 Hz and thus is optimized to most motors of this type.
Page 9
English LD-G-33 / LD-W-33
Load control (only with the LD-G-33)
The locomotive decoder LD-G-33 for DC motors has a load control, the
decoder LD-W-33 for AC motors does not have this function. The load
control influences the motor voltage to keep the locomotive 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 CV-variable
of the deocder. The parameters of the load control may be altered as well,
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 vibrates 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. Is the set value is too high
the locomotive vibrates massively while moving.
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
vibrates. Is the set value is too high, the locomotive shakes 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
velocity and the maximum velocity. From the starting velocity and the
maximum velocity the decoder generates a linear velocity characteristic.
Page 10
LD-G-33 / LD-W-33 English
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,
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.
Emergency stop
At a change of direction an emergeny stop is carried out automatically.
Slider commutation
The LD-G-33 or the LD-W-33 has a function output to be programmed
so that it switches a relay for slider commutation.
Function outputs
The decoder has six function outputs with a maximum current of 500 mA
each, which are available to connect optional accessories (e.g. lighting,
smoke generator, sound module, electric coupling). The decoder´s
maximum total current (including motor current) is 1.500 mA.
In DCC format the function outputs can be switched via the function keys
F0 to F12. In Motorola format the function outputs can be switched via
the function keys F0 to F4. The functions F5 to F9 can be switched via the
function keys F1 to F4 and F0 by assigning them to a second address.
The functions F10 to F12 are not available in Motorola format.
You can assign the function keys to the function outputs freely. It is
possible to assign several function keys to one function output.
Page 11
English LD-G-33 / LD-W-33
SUSI interface
A SUSI module can be connected to the LD-G-33 or the LD-W-33 and
programmed via the decoder. It is not possible to read the SUSI
module´s data via the decoder.
The locomotive 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).
Effects of the function outputs
It is possible to set the following effects for all function outputs individually:
Dimming: The voltage applied to an output can be reduced by
programming the decoder accordingly. 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. In
addition, it is possible to dim the voltage 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.
Kick function: It is possible to set the function outputs so that they
get the full voltage first for up to 20 seconds and then are dimmed.
Example of use: For some types of electric couplings you need the full
voltage for decoupling and the voltage then reduced to protect the
couplings. In addition it is possible to program the outputs so that the
locomotive moves a short distance from the disengaged carriages
automaticalley after releasing the kick function.
Flashing. Both the frequency and the keying ratio can be set. Examples
of use: single and alternating flash lights or strobe lights.
Switching on and off depending on the direction of travel: Any
output can be programmed to be switched on and off depending on the
direction of travel.
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: With some layouts it is customary that the tail lamps
of parked locomotives have to be temporally set at the front and the back.

LD-G-33 / LD-W-33 English
Feedback with RailCom
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 control
unit or to special receivers (so-called detectors). The decoders must be
designed to send the RailCom messages.
The LD-G-33 / LD-W-33 sends (continuously) the (basic, extended or
consist) address to the detectors (so-called RailCom broadcast datagramm)
and transfers 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. That is the reason why it is not possible to use the RailComfunction in a pure Motorola environment, but only when at least one other
locomotive or function decoder on the layout is controlled in DCC format.

6. Mounting the locomotive decoder
Before mounting the decoder check if the maximum locomotive
motor´s current on-load is below the maximum permissible value of
1.000 mA. If it is above 1.000 mA the decoder is not suitable for
mounting in this locomotive. It would be damaged when put into
operation.
Connecting the motor
Open the locomotive housing. Locate the position for the decoder.
Disconnect the motor from the rail current collector 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 LD-G-33
Follow the connection diagram fig. 1. Solder the connections from the
rail current collectors at the points X1 and X2.
Next solder the connections to the motor at the points X3 and X4. In
case the locomotive´s direction of motion in analogue mode does not
match the direction of motion set at the speed control you have to
swap the connections to the points X3 and X4.
Connecting the LD-W-33
Follow the connection diagram fig. 2. Solder the connection to the slider
at point X1, and the connection to the housing to point X2. These two
connections can be exchanged without effecting functionality.
Page 14
LD-G-33 / LD-W-33 English
!
!
!
!
Next solder the connections of the field coil to the points X3 and X4 and
the connection of the motor sheild to the point RL. 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 points X3 and X4.
Connecting accessories to the outputs
Before connecting the lighting and other accessories to the outputs
check if the current is below the maximum permissible value of 500 mA
per output and the total current is below 1.500 mA (including motor
current). If lighting or other accessories with current larger than
500 mA are connected, or if the total current of the motor and the
accessories is higher than 1.500 mA the decoder will be damaged when
put into operation.
Disconnect any existing diodes in the leads to the lamps. Connect the
lamps and the accessories to the function outputs (AUX1 to AUX6) of
the decoder. The assignment of the function outputs to the function
keys will be made when programming 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 return conductor of the
decoder (point RL).
Caution:
If you connect the accessories to the return conductor for all functions
(point RL), the accessories must be insulated. The accessories should
not make contact with metal parts of the vehicle. Possible short circuit!
The decoder will be damaged in operation.
Caution:
The return conductor for all functions (point RL) must under no
circumstances be connected to vehicle ground. Possible short circuit!
The decoder will be damaged in operation.
Page 15
English LD-G-33 / LD-W-33
!
Tip: Before starting to program the locomotive decoder you should
connect the motor to the decoder. Otherwise there is no confirmation
signal from the (DCC-) central unit. Should you intend to program the
decoder with a Motorola central unit you should always connect the
lighting to the outputs AUX1 and AUX2. The locomotive indicates the
change-over to the programming mode and the taking-over of settings
by flashing of the lighting connected to these outputs.
Decoder factory settings
If you want to use the decoder factory settings, you have to connect
the lighting and the accessories as follows:
Front lighting: AUX1
Back lighting: AUX2
Accessory switched via F1: AUX3
Accessory switched via F2: AUX4
Accessory switched via F5: AUX5
Accessory switched via F6: AUX6
Connecting a SUSI module
The decoder has four soldering points for the connection of a SUSI
module. You will find the pin connection in fig. 4.
Connecting the LEDs
The function outputs of the decoder (AUX1 to AUX6) switch respective
to the decoder ground. For that reason you must connect the cathode
(-) of the LED to the function outputs.
Caution:
If you use light-emitting diodes (LEDs) you must always operate them
via a series resistor. LEDs are available in many different models. The
series resistor limits the current flow of the LED and will need to be
calculated for each model. Ask for the max. current rating when buying
your LEDs.
Page 16
LD-G-33 / LD-W-33 English
You can connect several LEDs in parallel to each output. In this case
every LED must have a series resistor of its own. If you connect several
LEDs to one output in series, only one series resistor is needed.
Connecting a smoothing capacitor
In track sections with bad contacts the power supply may be
interrupted shortly. You can solder a capacitor between the points
"Elko-" and "Elko-" to counteract this effect (see fig. 4).
Fixing the locomotive decoder
After completing all connections fix the locomotive decoder with doublesided adhesive tape, for example.
Using a NEM 652 interface connector
Some locomotives with DC motors 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 below shows how to connect the contacts of the interface
connector to the connecting points of the locomotive decoder.

7. Programming the locomotive decoder
In DCC format it is possible to program register or configuration
variables (CVs), main track programming can be used as well. In
Motorola format the settings are saved in registers.
Programming with DCC central units
You can programm the configuration variables (CV) of the decoder from
the digital central unit. See the chapter in the manual of your central
unit where the byte wise programming of configuration variables (CVs)
is explained. With central units that allow only register-programming it
is only possible to program the variables CV#1, CV#2, CV#3, CV#4 and
CV#29 (= register 1 to 5).
Programming with the Central Station and the Mobile Station
With the Central Station or the Mobile Station of Märklin** you can
program the registers, but the value to be set is limited to 80. 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.
Programming with Motorola central units
Put the locomotive on a track oval or a track section connected to the
central unit’s track output. 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.
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.
Reset the central unit (by simultaneously pushing the buttons "stop"
and "go" for some time) or quickly switch the central unit off and on. First
enter the current address or the address "80" (e.g. if you do not know the
Page 18
LD-G-33 / LD-W-33 English
current address). Manufacturers setting is "3". Set all functions (function,
f1 to f4) to "off".
Push the "stop" button at the central unit. Next, operate the direction
switch and hold it in that position while briefly pushing the "go" button.
As soon as the lamps connected to the outputs AUX1 or AUX2 flash
(after approx. 2 seconds) the decoder is in the programming mode and
you an release the direction switch.
Starting the programming mode
Switch on the central unit or
perform a reset at the central unit.
Set the current address or address 80.
Set all functions to "off".
Push button „stop“
à Switch off the track voltage.
Operate the direction switch and hold it in
that position. Briefly push the button „go“.
As soon as the lighting flashes,
release the direction switch.
Start register-programming
(lighting flashes)
Page 19
English LD-G-33 / LD-W-33
After having started the programming mode (and when the
locomotive´s lighting flashes) you can program the decoder´s registers
as follows:
1. Choose the register you want to programm by setting the register´s
number with the Motorola locomotive address at your central unit.
Please note that with some central units a leading "0" has to be
entered.
2. Operate the direction switch. The lighting flashes faster.
3. Set the desired value of the register by setting the register´s value
as Motorola locomotive address at your central unit.
4. Operate the direction switch again. The lighting starts flashing
again.
Repeat the steps 1 to 4 for all registers you want to program. In order
to choose a register for programming or to enter a value for a register
you have to confirm the entered number like selecting a Motorola
locomotive address. The lighting shows which kind of entry the decoder
expects:
§ lighting flashes à entry of a CV´s number
§ lighting flashes faster à entry of a CV´s value
In order to stop the programming mode push "stop".
8. Configuration variables and registers
of the LD-G-33 and the LD-W-33
The following list shows all configuration variables (for the DCC format)
and registers (for the Motorola format), that can be set for the LD-G-33
and the LD-W-33.
In the list you will find in the column "CV-no." the numbers of the
configuration values for programming in DCC format and in the column
"Reg.-no." the numbers of the registers for programming in Motorola
format. The defaults are those values set in the state of delivery and after
a reset.
Page 20
LD-G-33 / LD-W-33 English
* For some configuration variables, the input values have to be calculated
by adding the numerical values assigned to the desired parameters.

without a leading "9".
Example: Programming the CV#902 of the SUSI module to the value "8":
By entering the value "9" for CV#7 of the decoder, the programming mode is
started. Next the CV of the SUSI module is chosen by entering a "2" or "02"
(leaving out the leading "9") and for the CV#902 the value "8" is set. The
decoder automatically goes back to the programming of it´s own CVs. In order
to programm another CV of the SUSI module, the operation has to be repeated
completely.

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
locomotive has to be prevented from changing over into analogue mode and it
has to be ensured that the locomotive reacts as expected on the braking route.
When braking with positive or negative d.c. voltage is set for the decoder, the
analogue recognition is switched off automatically.
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.

9. Operation
Optimising the CV-settings
Above all, the driving characteristics can be influenced by setting the CV#2
(starting voltage) and CV#5 (Maximum voltage) and for the LD-G-33, in
addition, the CV#50 to #52 (parameters of the load control).
As a rule, the following settings lead to good driving characteristics :
Motor CV#2 CV#5 CV#50 CV#51 CV#52
HLA 3 160 40 20 50
GFN old 8 200 10 8 150
PIKO 4 200 20 12 50
HAMO 4 150 10 11 40
ROCO new 2 220 30 25 80
Requirements for the operation with RailCom
For reading out the data via RailCom, special detectors and boosters
compatible with RailCom are required.
It is not possible to read out data via RailCom unless in the CV#29
(DCC format) or the register #07 (Motorola format) of the locomotive
decoder RailCom is switched on.
RailCom-Messages can only be transferred in model railway layouts with
a DCC signal on the rails. When the locomotive decoder is operated in
Motorola format, RailCom messages cannot be sent unless
simultaneuously at least one other locomotive or function decoder is
controlled in DCC-Format.

10. Check list for trouble shooting
§ 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. The decoder is connected to
locomotive or carriage ground. à Check the connections. A short
circuit can result in irreparable damage.
Possible cause: The connection of the motor is connected to locomotive
ground. à Disconnect the connection from locomotive ground.
§ 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.
§ An output cannot be switched on.
Possible cause: The values set in CV#53 to 58 for an output,
contradict one another. à Alter the values for CV#53 to 58.
§ The locomotive does not run in analogue mode.
Possible cause: The analogue mode is switched off. à Alter the value
for CV#29.
§ 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
Page 34
LD-G-33 / LD-W-33 English
speed levels, but the decoder to the mode 14 speed levels. à Change
the speed mode at the central and / or at the decoder.
§ The CV values cannot be read out.
Possible cause: RailCom is switched off. à Alter the value of
CV#29.
If you cannot find the problem, please return the decoder for repair
(address on the cover page).
