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.
Page 4
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.
Page 7
English Locomotive decoders 30s series
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.
Page 10
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.
Page 12
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.
Page 14
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.

6. Mounting the locomotive decoder
Caution:
!
Before mounting the decoder check if the maximum locomotive
motor´s current on-load is below the maximum permissible value. If it
is above the decoder is not suitable for mounting in this locomotive. It
would be damaged when put into operation or with decoders with
overload protection (LD-G-30, LD-G-33 and LD-G-34) switched off.
LD-G-decoders: Using decoders with interface connectors
Many recent locomotives with d.c. motor are equipped ex works with an
interface socket according to NEM 651, NEM 652 or NEM 658. The
interface enables you to connect the motor to the motor, the rail
current collectors, the lighting and – provided the special connector is
designed for it – additional accessories.
Using a decoder with a suitable connector saves separating the
connections and soldering works at the locomotive. When mounting
decoders with 6-pole interface connectors according to NEM 651 or 8pole 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
12-pole PluX-connectors according to NEM 658 can be mounted in one
direction only.
Mounting decoders without interface connector
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
Page 17
English Locomotive decoders 30s series
suppression devices are one unit. If even one part is removed, it can
cause extreme interference!
Connecting the decoder
Follow the connection diagram for the particular decoder.
Decoder for DC motors (LD-G-decoder): Connect the decoder to the
rail current collectors and to the motor.
Decoder for AC motors (LD-W-decoder): Connect the decoder to the
connections from the slider and the housing. These two connections
can be exchanged without effecting functionality. Next connect the
connections of the field coil and the connection of the motor shield to
the decoder.
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.
Connecting accessories to the outputs
Before connecting the lighting and other accessories to the outputs
check if the output´s current is below the maximum permissible value
and the total current is below the safe load (including motor current).
!
Caution:
Should the permissible output current is exceeded, this normally results
in permanent damage to the output. Exceeding the decoder´s total
current will lead to damage or, with decoders with overload protection
(LD-G-30, LD-G-33 and LD-G-34) to switching off the decoder.
Disconnect any existing diodes in the leads to the lamps. Connect the
lamps and the accessories to the function outputs of the decoder. The
assignment of the function outputs to the function keys will be made
when programming the decoder.
Page 18
Locomotive decoders 30s series English
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. The overload protection of
the decoders LD-G-30, LD-G-33 and LD-G-34 cannot protect them from
being so damaged.
!
!
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. The overload protection of
the decoders LD-G-30, LD-G-33 and LD-G-34 cannot protect them from
being so damaged.
Tip: Before starting to program the locomotive decoder you should
connect the motor to the decoder. Otherwise there is no confirmation
signal to 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, intended to connect the front and the back
lighting ex works. 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.
Page 19
English Locomotive decoders 30s series
Connecting the LEDs
The function outputs of the decoder 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.
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.
LD-G-31: Connecting a loudspeaker
Use a loudspeaker as large as possible with an impedance of at least
8 Ohm. Decisive for the sound reproduction is the correct mounting of
the loudspeaker. 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. If necessary, use a loudspeaker with a sound
cartridge. 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.
Connect the loudspeaker to the points X1 and X2 of the decoder.
LD-G-33, LD-G-34 und LD-W-33: Connecting a SUSI module
The decoder has four soldering points for the connection of a SUSI
module. You will find the pin connection in the connection diagram for
the particular decoder.
Page 20
Locomotive decoders 30s series English
Connecting a smoothing capacitor
In track sections with bad contacts the power supply may be
interrupted shortly. With those locomotive decoders with enough space
on the PCB (LD-G-32, LD-G-33, LD-G-34, LD-W-32, LD-W-33) you can
solder an additional capacitor to counteract this effect (see connection
diagram of the particular decoder).
Fixing the locomotive decoder
After completing all connections fix the locomotive decoder with doublesided adhesive tape, for example.

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. With the auxillary register #62 values above 80 can
be entered. 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 22
Locomotive decoders 30s series 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 can 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 23
English Locomotive decoders 30s series
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 like a 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".
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 CV-
Navi. You will find the free download under:
www.tams-online.de

8. Configuration variables and registers
The following list shows all configuration variables (for the DCC format)
and registers (for the Motorola format), that can be set for the
locomotive decoders of the 30s series.
In the list you will find in the column "CV-no." the numbers of the
configuration variables 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.
* For some configuration variables, the input values have to be calculated
by adding the numerical values assigned to the desired parameters.

Braking
performance
with d.c.
voltage
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.

applied to the output. The
value "1" corresponds to the
minimum, "15" to the max.
voltage. The values are only
valid for the outputs defined
in CV#116 and for the speed
level defined in CV#113.
It is possible to choose a value between 0 and 15 for any of the outputs. For the
outputs with an odd number the value is set directly, for the outputs with an
even number the input value has to be multiplied by 16.
Example:
For AUX5 value "14" and for AUX6 value "2"à input value: 46 (=14 + 2x16)

English Locomotive decoders 30s series
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 decoders for
d.c.motors (LD-G-versions), in addition, by setting the CV#124 (optimizing
the load control) and the CV#50 to #52 (parameters of the load control).
Make the setting for the load controlled decoders (LD-G-decoders) in the
following order, as far as required:
1. CV#124
2. CV#50 to #52
3. CV#2 and CV#5
To adjust the parameters for the load control (CV#50 to #52) the
following procedure is recommended:
If the locomotive is shaking: à Increase the value for CV#52 (KD) in 5steps. If this does not lead to an improvement of the driving
characterists, 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 shake. Then increase the value for CV#52
(KD) in 5-steps. If this does not lead to an improvement or the
locomotive starts to shake 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 shaking heavily: à Decrease the value for CV#52
in 5-steps.

9. 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 CV values cannot be read out by RailCom.
Possible cause: RailCom is switched off. à Alter the value of
CV#29.
Page 43
English Locomotive decoders 30s series
§ 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. à Change
the speed mode at the central and / or at the decoder.
§ LD-G-30, LD-G-33 and LD-G-34 only: 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.
If you cannot find the problem, please return the decoder for repair
(address on the cover page).
