Safety Notes; Technical Data - L. G. B. 55029 Manual Del Usuario

These instructions describe the installation and
options for settings on the 55029 decoder, which can
be used for LGB locomotives as well as for 1 Gauge
locomotives.
Retrofitting a locomotive model with a new decoder
requires extensive knowledge about the technology
used in that model, the programming of electronics,
as well as skills in doing repairs. In case of doubt, you
should therefore always go to a specialist for such
conversion work. The individual doing the conversion
is solely responsible for damages to the individual com-
ponents installed or damages to other parts resulting
from incorrect selection of components, unprofessional
installation, or incorrect settings on the components.

Safety Notes

• WARNING! Sharp edges and points required for
operation.
• Not for children under the age of 15.
• Do wiring and assembly work only on a voltage-free
or grounded work mat. Failure to do this can lead
to dangerous static charge from your body and to
damage to the components.
• Operate the decoder only with the authorized
voltage (see technical data).
There is a danger of burning yourself when working
with a soldering station.

Functions
• Automatic system recognition.
• Acceleration and braking delay can be set separa-
tely from each other.
• Alternative „constant braking length".
• Programming on Main (PoM), this programming
must be supported by the controller. To do this,
follow the operating instructions for your controller.
• Adjustable switching range.
• Braking / signal stopping section recognition in
digital operation.
• Especially fine motor control.
• Automatic setting for the motor control with a „Cali-
bration Run".
• Wide ranging function mapping. Independent com-
bination of functions.

• Functions can be controlled with up to two (2) reed
contacts (not included).
• The volume can be set extra for each sound.

The setting and digital functions can only be used in
digital operation. However, the same options are not
available in all protocols.
Installation
Interface
The decoder is designed for an mtc27 interface. On
locomotives with this interface, (see list on page 34)
the decoder can be plugged in directly. The adapter
board included with this decoder must be used with all
other locomotives.
Sound
The decoder comes from the factory with the sounds
set for a class Ge 4/4 II electric locomotive. These
sounds can be replaced by doing programming. The
60971 Programmer (Märklin) and the 55129 Program-
ming Adapter (LGB) are required to do this. When
doing this, make sure to follow the 60971 instructions,
in which the procedure is described.
The speaker included with the decoder can be used
the first time you run the locomotive with the decoder.
The speakers from comparable locomotives can also be
used to get better sound results (See list on page 34).
The decoder has inputs for a clock and for two (2)
sensors to activate sounds.
Installation
The decoder can warm up in operation due to the high
performance of the motors. The installation location for
the decoders should be selected so that the decoder is
well ventilated.
The locomotive must be checked for trouble-free
mechanical and electrical function before installing
the decoder. It may be that the locomotive must be
repaired before the conversion. We cannot cover the
warranty for damages caused by unprofessional work.
Note: The AUX outputs on the decoder are preset for
the use of light bulbs (18 volts).
1 Open the locomotive following the information in the
operating instructions. Determine the installation
spot for the decoder.
2 If may be necessary to remove the existing electro-
nics.
3 Connect the wires according to their assignments
(see page 23). Insulate the ends of the wires that
will not be used. Pay attention to the recommended
wire cross sections.
Do not do any soldering on the decoder itself.
4 Install the circuit board. Make sure you mount
the circuit board securely (example: double-sided
adhesive pad). There must not be any short circuits
caused by touching metallic or electrically conductive
