English Locomotive decoders 30s series
1. Getting started
This manual applies to all locomotive decoders of the 30s series, so for:
§ locomotive decoder LD-G-30, LD-G-31, LD-G-32, LD-G-33 and
LD-G-34 and
§ locomotive decoder LD-W-32 and LD-W-33.
Provided there are no other details given for particular sections, the
information given applies to all decoders.
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 decoders of the 30er series are designed for mounting
in model locomotives with DC motor (LD-G-decoders) resp. AC motor
(LD-W-decoders). They evaluate the Motorola or DCC format data sent
by the digital central unit to their addresses and control the
locomotive´s motors and additional functions.
The decoders 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.

Locomotive decoders 30s series English
! 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.
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 or PluX interface connector, depending on the
version,
§ 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, if
you have purchased a decoder without soldered interface connector:
§ 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),
In order to connect decoders without soldered connecting wires or
connectors you will need wire. Recommended cross sections:
§ > 0,05 mm² for connections to the function outputs
§ > 0,05 mm² for connections to the motor (except for the LD-G-34)
§ > 0,14 mm² for connections to the motor of the locomotive
decoder LD-G-34

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,
§ 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.
Page 6
Locomotive decoders 30s series English
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.
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.
§ 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 decoders of the 30´s series are multiple protocol
decoders, 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 decoders can be driven in all speed levels (14,
28 or 128).
In the Motorola format the decoders 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 DCC format by setting the
configuration variables and in Motorola format through the registers.
Operation in analogue mode
The locomotive decoders of the 30´s series can also be used in analogue
model railway layouts. They 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.
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
Page 9
English Locomotive decoders 30s series
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.
For LD-G-33 and LD-G-34 only: 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.
LD-G-30, LD-G-33, LD-G-34: Overload Protection
As soon as the maximum total current of the LD-G-30, LD-G-33 or LDG-34 is exceeded, the decoder automatically temporally switches off the
motor and the function outputs, in order to protect the decoder from
overheating.This operation will be repeated until the overload has been
eliminated. With the LD-G-30 and the LD-G-33 the sensivity of the
overload protection can be altered by programming a configuration
variable.
Caution:
!
When a short circuit caused by contact between decoder and housing
occurs the current as a rule is so high, that the overload protection
cannot protect the decoder from being damaged.

Locomotive decoders 30s series English
Driving of the motor
The differernt decoder types are designed to optimally control their
particular fitting motor types.
Decodertyp PWM Suitable for coreless
(Faulhaber) motors
LD-G-30 32 kHz (fixed) yes
LD-G-31 17 or 32 kHz (to be set) yes
LD-G-32 32 kHz (fixed) yes
LD-G-33 17 or 32 kHz (to be set) yes
LD-G-34 17 or 32 kHz (to be set) yes
LD-W-32 480 or 60 Hz (to be set) no
LD-W-33 480 Hz (fixed) no
LD-G-decoders: Load control
The LD-G-locomotive decoders for DC motors have a load control, the
decoder LD-W-locomotive decoders for AC motors do 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.
Page 11
English Locomotive decoders 30s series
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 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. If the set value is too high, the locomotive shakes while moving.
Velocity characteristic
The decoders 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.
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. When so programmed, it can be switched on and off
with the function key F3.
Emergency stop
It is possible to carry out an emergeny stop at a change of direction
automatically, when so programmed.

Locomotive decoders 30s series English
LD-G-33, LD-G-34 and LD-W-33: Slider commutation
The decoders LD-G-33, LD-G-34 and LD-W-33 have a function output to
be programmed so that it switches a relay for slider commutation. Due
to the principle of the slider commutation it does not work in sections
switched currentless (braking sections).
Function outputs
The decoders have two, four or six function outputs depending on the
type, 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").
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.
LD-G-31: Connections for a signal hooter
It is possible to connect a loudspeaker to the LD-G-31 (not included in
the package). Via two function keys two signal hooters with different
frequencies can be generated. You can assign the function keys freely.
LD-G-33, LD-G-34 and LD-W-33: SUSI interface
A SUSI module can be connected to the LD-G-33, LD-G-34 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).
Page 13
English Locomotive decoders 30s series
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.
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.
LD-G-31, LD-G-33, LD-G-34 and LD-W-33 only: 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 automatically
after releasing the kick function.
LD-G-31, LD-G-33, LD-G-34 and LD-W-33 only: 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.

Locomotive decoders 30s series 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.
When so programmed, the locomotive decoders of the 30´s series 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. 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.
