THE PROGRAM
This LGB model is part of the com-
prehensive LGB program of more
than 600 quality G-scale trains, track
sections and accessories. To learn
more about the many other products
in the LGB program, see the big LGB
catalog or visit www.lgb.com
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: Power to motor, lights
and couplers (factory
pre-set)
Hint: For sensitive slow speed
switching, you can engage the loco's
half-speed mode by pressing func-
tion button 8 (see Multi-Train System).
Attention: Do not connect this model
to other loco models with different
starting characteristics. This can
damage the internal gearing.
Operating the couplers
With the Multi-Train System, the
couplers can be operated remotely
(see Multi-Train System). Press the
F2 button to lower or raise the front
coupler, F3 for the rear coupler. The
couplers cannot be operated with
analog operation.
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 control the loco’s
functions remotely. Press the light-
ing button (“9” with remotes) to turn
the loco lights on or off. Press the
function buttons to control the fol-
lowing functions:
2: Front coupler hook down/up
(right roof light illuminated:
coupler lowered)
3: Rear coupler hook down/up (left
roof light illuminated: coupler
lowered)
8: Half-speed mode on/off
With a Loco Remote or Universal
Remote, press the numbered loco
function buttons. For example, to
lower the front coupler hook, press
button “2” on the Loco Remote or
Universal Remote.
When using the MTS components
marked with a “p,” this loco can receive
"parallel" function commands, which
eliminate the pause that occurs when
a "serial" command is received.
Parallel: Command is send directly.
Serial: Command is send as a string
of "1" commands, for example, 3 = 1
+ 1 + 1).
Most MTS components can be
upgraded to parallel function com-
mands (Exceptions: first generation
55000 MTS Central Station, 55010
Train Mouse). For more information,
contact your authorized retailer or go
to www.lgb.com.
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 with the 55015 Universal
Remote.
Lighting
This model features directional light-
ing. The model has a "flat" multi-pur-
pose socket, with a removable cover,
on the rear of the cab (Fig. 3). This
socket can be used to provide track
power to LGB cars with lighting or
sound electronics.
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.
