How to use this manual
Even if you have no specialist technical training, this manual gives step-
by-step instructions for safe and correct fitting of the module, 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 module 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. It evaluates the Motorola format data sent by the digital
central unit to its address and controls the locomotive´s motor and
additional functions.
The module 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 very
sensitive to static electricity. Do not touch components without first
discharging yourself. Touching a radiator or other grounded metal part
will discharge you.

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 module.
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.

Operation overview
The decoder is designed for operation in Motorola II format and can be
adjusted to one of 255 addresses. It evaluates the digital data sent by the
central unit to its address. It controls the locomotive’s motor and the
driving characteristics. In addition, it switches four function outputs,
which can for instance be used for the locomotive’s lighting.
In Motorola I format it is possible to operate the decoder, but the
programming of the parameters and the controlling of the functions is
restricted.
Automatic recognition of the analogue mode
The decoder can also be used in analogue model railway layouts run with
an A.C. speed control. When putting the locomotive 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 by programming the decoder
accordingly.
LD-G-14 English
Page 35
The decoder is not suitable for being operated in analogue model railway
layouts run with an D.C. speed control. The decoder evaluates the data
received in such layouts as "braking section", the locomotive therefore
does not run.
In analogue mode the decoder reacts to the analogue changing
direction signal. The lighting is always switched on according to the
direction of travel. Switching on or off the lighting and the additional
functions is not possible.
Driving of the motor
The locomotive decoder drives the motor with a PWM of 16 kHz. This
guarantees a soft and constant run of the motor, with which the
decoder can also be used with coreless (Faulhaber) motors.
Load control
The locomotive decoder has a load control. 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).
The decoder chooses automatically the optimal values of the load
control´s parameters for the connected motor. The range of values
from which the decoder chooses the optimal value can be altered by
programming the decoder accordingly.
Direction of motion
When changing the direction in digital operation the existing direction is
saved and so retained, even if the central unit does not send absolute
driving data (e.g. in Motorola I format).
In order to change the direction of travel in analogue operation a
voltage impulse is applied to the rails which is distinctly higher than the
normal driving voltage. Disturbances from the locomotive motor,
tolerances in the connected components or voltage drops in the rails
can release unintended changes of direction or hinder intended changes
of direction. The voltage needed for a change of direction can be
adjusted by programming the decoder accordingly.

Speed level
The decoder can drive 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 only allow 14 speed levels
only, it is only possible to select every second speed level.
Velocity characteristic
The decoder can be adjusted to the individual
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
velocity characteristic corresponding to the
opposite figure. This characteristic allows a
good fine tuning of the speed in the lower
speed range.
Shunting gear
The auxiliary function F4 allows you to switch into the shunting gear
mode. In the shunting gear mode the velocity of all speed levels is
reduced to ca. 25 % compared to the standard velocity.
Acceleration and brake delay
It is possible to program the acceleration and brake delay individually.
You can switch the acceleration and the brake delay on or off by
operating the function key F3. Even if the acceleration and the brake
delay are active you can actuate an emergency stop via the central unit
by reversing the direction of travel.
Function outputs
The decoder has four function outputs which can be switched on and
off via the function keys „function“ and / or the auxiliary function keys
F1 to F4. They are available to connect optional accessories (e.g.
lighting, smoke generator, sound module, electric coupling).
x = speed grade
y = motor voltage
LD-G-14 English
Page 37
The set states of the function outputs are saved. Even if the decoder is
without current for a longer time, the states are set when the decoder
is switched on again.
Assignment: You can assign the function keys to the function outputs
freely. It is possible to assign several function keys to one function output.
Each function output can be programmed in such a way that it can be
switched
§independent of the direction of travel with all function keys or
§dependent of the direction of travel with all function keys or
§dependent of the direction of travel with F0 („function“) and
independent of the direction of travel with F1 to F4.
Example of use: The lighting of a shunting locomotive is assigned both
to the function key „function“ as to the function key F4. In shunting
operation you switch the lighting via F4 and in standard operation
according to the direction on travel via „function“.
Dimming: All function outputs can be dimmed individually.
Example of use: The electric bulbs of older locomotives made for
analogue operation can be dimmed and thus must not be exchanged
after the mounting of the decoder.
Example of use: The front lighting is assigned to two different function
outputs. Via one function key you can switch the standard lighting, via
another the long distance lighting.
Flash lights: It is possible to program a flash light for all function
outputs. Two flashing phases are available out-of-phase by 180
degrees. Example of use: individual flash lights or alternating flash
lights.
CV programming
Setting the address, the driving characteristics (starting and maximum
velocity, acceleration and brake delay) and the velocity characteristic
and adjusting the decoder to the particular locomotive motor (motor
frequency, voltage for change of direction, load control parameters) as
well as the definition of the function outputs´characteristics is done by
