OPERATION
Operating Modes
This model has a three-way power
control switch in the cab (Fig. 1, 2):
Position 0: All power off
Position 1: Power to motor and lights
Position 2: Same as Position 1 (fac-
tory pre-set)
Attention: Do not connect this model
to other loco models with different
starting characteristics. This can
damage the internal gearing.
Multi-Train System
The model is equipped with a facto-
ry-installed onboard decoder for the
LGB Multi-Train System. It can be
used without modifications on ana-
log or digital layouts. For operation
with the Multi-Train System, the
model is programmed to loco
address 03. For information on pro-
gramming the loco address, see the
instructions for various MTS compo-
nents.
When operating with the Multi-Train
System, you can remotely control the
loco's functions. Press the lighting
button ("9" with remotes) to turn the
loco lights on or off.
When operating with the Multi-Train
System, the loco features a "Back-
EMF" function. This keeps the motor
speed constant (and under normal
conditions the loco speed), even
when the load of the loco changes,
for example, in curves or on grades.
This feature does not work at top
speed, because additional voltage
must be available to overcome any
added load.
If desired, numerous functions of the
onboard decoder, such as accelera-
tion, braking, direction of travel and
many others, can be programmed
using a PC and the 55045 MTS PC
Decoder Programming Module (see
Instructions for advanced users).
These functions also can be pro-
grammed from the 55015 Universal
Remote.
Lighting
The lights of this model illuminate
when the model moves forward. The
model has a "flat" multi-purpose
socket, with a removable cover, on
the rear wall (Fig. 3). This socket can
be used to provide track power to
LGB cars with lighting or sound elec-
tronics.
To remove the cover of the socket,
pull it straight out. If the cover is
tight, gently use a small straight
screwdriver to pry it out. (Do not pull
out the rectangular outer housing.)
Power Supply
Attention! For safety and reliability,
operate this model with LGB power
supplies (transformers, power packs
and controls) only. The use of non-
LGB power supplies will void your
warranty.
Use this model with LGB power sup-
plies with an output of at least 1
amp. For more information on LGB
power supplies for indoor, outdoor
and multi-train operation, see the
LGB catalog.
Attention! After extended operation,
this model may leave carbon dust or
other debris around the track. This
dust and debris can stain carpet and
other materials. Consider this when
setting up your layout. Ernst Paul
Lehmann Patentwerk and LGB of
America are not liable for any dam-
ages.
