Information: Motorola I and Motorola II format
The digital driving data is differently encoded and transmitted in the
(old) Motorola I format and the (new) Motorola II format. The
locomotive decoder is designed to evaluate data in Motorola II format.
This limits its use in Motorola I format.
Since data of the auxiliary functions F3 and F4 sent in Motorola I Format
cannot be evaluated by the locomotive decoder, it is not possible to
switch these functions on or off when using Motorola I format.
Unlike the Motorola II format, no absolute direction data is sent in
Motorola I format, but a single driving signal reverses the direction of
travel. This has the following consequences:
1. If the change direction command is not recognized by the
locomotive, it continues in the original direction.
2. If the decoder is switched off for some time and the direction data is
not saved, the locomotive continues in its favourite direction when it is
switched on again.

LD-G-3 / LD-W-3 English
Page 27
Operation overview
The decoder is designed for operation in Motorola I or II format and can
be adjusted to one of 255 adresses. It evaluates the digital data sent by
the central unit to its address and transmitts it to the locomotive.
Function speed level and direction of motion
The speed level set at the central unit and the change-direction
command are transmitted to the locomotive by the decoder. At a
direction change command, the current direction of travel is saved.
Velocity characteristics
By adjusting the starting and the maximum velocity an individual
velocity characteristic can be programmed via the central unit. The
adjustments set the actual motor voltage of the locomotive. The motor
voltage has an immediate effect on the driving speed of the locomotive
at a chosen speed level during the operation.
The operating voltage of the locomotive motor at speed level 1 is set by
adjusting the starting velocity. Normally the motor voltage is adjusted
so that the locomotive just starts to run at speed level 1.
The operating voltage of the locomotive motor at speed level 14 is set
by adjusting the maximum velocity. The adjustment should be such that
the locomotive reaches the desired maximum speed at speed level 14.
The operating voltages of the locomotive motor at speed levels 2 to 13
are linearly interpolated.
Acceleration and brake delay
14 different steps are available for the acceleration and brake delay.
The acceleration and brake delay can be switched off via the auxiliary
function F3.
Function lighting
The lighting can be switched on and off according to the direction of
travel from the central unit via the function "function".

English LD-G-3 / LD-W-3
Page 28
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. 50 % compared to the standard velocity.
Restrictions in Motorola I format
The auxiliary functions F3 and F4 are not available in Motorola I format.

§a soldering iron stand with tip-cleaning sponge
§a small side cutter and wire stripper
§an electronic soldering iron (max. 30 Watt) with a fine tip
§tin solder (0,5 mm. diameter)
§wire (diameter: >0,05 mm²)
Safe and correct soldering
Caution:
Incorrect soldering can cause fires (through excessive heat). Avoid this
danger by reading the chapter Safety instructions again and
following the directions given.
If you have had training in soldering you can skip this chapter.
§When soldering electronic circuits never use soldering-water or
soldering grease. They contain acids that can corrode components
and copper tracks.
§Only use tin solder SN 60 Pb (i.e. 60 % tin, 40 % lead) with rosin-
based flux.
§Solder fast: long soldering can destroy components and copper
tracks, and damages through plated holes.
§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.
§Apply the soldering tip to the soldering spot in such a way that the part
and the soldering spot 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
tin solder finds its way, then remove the soldering iron.
§To make a good soldering joint you must 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.
§Do not move the component for about 5 seconds after soldering. A
glossy and perfect soldering spot should remain.

Performing a visual check
Damaged materials can cause injury. Parts damaged during transit can
also be dangerous.Check the module for damage, missing parts or poor
soldering. If you find damage, return the module for exchange.
Mounting the locomotive decoder
Open the locomotive housing. Locate the position for the decoder.
Disconnect the motor from the rail current collector respectively 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
suppression devices are one unit. If even one part is removed, it can
cause extreme interference!
Connecting the LD-G-3
Follow the connections diagrams (fig. 1)! Solder the connection to the
slider at point X2, and the connection to the housing to point X3. These
two connections can be exchanged without effecting functionality.
Solder the connections to the motor at the points X10 and X11.
Connecting the LD-W-3
Follow the connections diagrams (fig. 2)! Solder the connection to the
slider at point X2 and the connection to the housing to point X3. These
two connections can be exchanged without effecting functionality.
Solder the connections to the motor at the points X6, X10 and X11.
Connecting the lighting
Follow the connections diagrams (fig. 1, 2 and 3)!
Disconnect any existing diodes in the leads to the lamps. Connect the
lamps for forward motion to X5 and the lamps for reverse to point X4.

LD-G-3 / LD-W-3 English

!
If the lamps are already connected with one side to locomotive ground,
the connection is complete. If not, connect the second side of the
lamps to the return conductor (point X1 resp. X6).
Caution:
The return conductor for all functions (point X1 resp. X6) must under
no circumstances be connected to locomotive ground. Possible short
circuit! The locomotive decoder will be damaged in operation.
Tip: If the second side of the lamps is connected to locomotive ground
the lamps often flicker in operation. You can avoid the flickering of the
lamps if you connect the second side to the return conductor (point X1
resp. X6) instead of locomotive ground.
Caution:
If you connect the lamps to the return conductor for all functions (point
point X1 resp. X6), the lamps must be insulated. The lamps must not
make contact with metal parts of the locomotive. Possible short circuit!
The locomotive decoder will be damaged in operation.
Connecting the LEDs
The function outputs of the locomotive decoder switch against decoder
ground. For that reason you must connect the cathode (-) of the LED to
the output of the relevant function.
Caution:
If you use light-emitting diodes (LEDs) you must always operate them
via a series resistor.
LEDs are available in many different models. There are LEDs with 2-5
mA, but also LEDs with 15-30 mA power consumption. 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.

Fixing the locomotive decoder
After completing all connections fix the locomotive decoder with double-
sided adhesive tape, for example.
Using an NEM 652 interface connector
Some locomotives already have an NEM 652 interface connector
mounted. Using a convenient connecting plug you save disconnecting
the connections and you do not need to solder at the locomotive.
The list shows how to connect the contacts of the interface connector
to the connecting points of the locomotive decoder.

Programming the locomotive decoder
You can make the following adjustments from the central unit without
intervention at the locomotive:
1. Locomotive address
2. Startingvelocity
3. Maximum velocity
4. Acceleration and brake delay
The order of this list corresponds to the sequence of the single menu
points in the programming mode.

LD-G-3 / LD-W-3 English
Page 33

Online-programming
In the programming mode, the starting velocity, the maximum velocity
as well as the acceleration and brake delay are tested and directly
saved. For that reason you need an isolated oval section of track for
programming. As soon as you finish a menu point, i.e. before you
switch the function "function" to "off", you should always set the speed
control knob to "0". Otherwise the locomotive starts to run at the
beginning of the following menu point.
Entering the present address is not necessary to access the
programming mode of the decoder. The decoder which is on the
programming track is programmed after the switching-over into the
programming mode. To avoid unintended programming of a decoder,
no other locomotives with this decoder type should be on a track
connected to the programming track.
Accessing the programming mode
Put the locomotive on to the track and reset the central unit. Set the
function "function" of the central unit to "off". Enter the address "78" at
the central unit.
Caution:
It does not matter if you have already saved a new address. You
always have to enter the address "78" to access the programming
mode.
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 front lamp of the locomotive flashes (after ca. 2
seconds) you are in the programming mode and can release the
direction switch.
Notice: Some types of central units do not allow you to access to the
programming mode when the Motorola II format is set (e.g. Intellibox*
from Uhlenbrock). These central units must be set to Motorola I format
to program the locomotive decoder.

English LD-G-3 / LD-W-3
Page 34
1. Programming the locomotive address
After accessing the programming mode enter the present or the new
locomotive address. It is not necessary to enter the old address if you
intend to enter a new locomotive address. Confirm the input by
switching on the function "function". The locomotive confirms the input
by flashing the front lamp once. Set the speed control knob to "0". To
access the following menu point, switch off the function "function".
2. Programming the starting velocity
Turn the speed control knob. As soon as the locomotive is running with
the starting velocity you want switch on the function "function". The
locomotive confirms the input by flashing the front lamp twice. Set the
speed control knob to "0". To access the following menu point, switch
off the function "function".
3. Programming the maximum velocity
Turn the speed control knob. As soon as the locomotive is running with
the maximum wanted velocity, switch on the the function "function".
The locomotive confirms the input by flashing the front lamp three
times. Set the speed control knob to "0". To access the following menu
point, switch off the function "function".
4. Programming the acceleration and brake delay
Operate the speed control knob. Now the locomotive accelerates and
brakes alternately. By setting a low speed level you obtain a fast
acceleration and brake delay, by setting a high speed level you obtain a
slow acceleration and brake delay. While accelerating the front lamp of
the locomtive is off, when braking it is on. Set the acceleration and
brake delay required and switch on the function "function". The
locomotive confirms the input by flashing the front lamp four times. Set
the speed level to "0" while the lamp flashes, otherwise the locomotive
will run with this speed level when the standard operation starts.
With that the programming is finished, the decoder automatically
switches to standard operation.

LD-G-3 / LD-W-3 English
Page 35
Skipping single menu points
If you want to skip single menu points set the speed control knob to
"0", and switch the function "function" on and off once. The decoder
retains the driving characteristics that have already been saved. The
decoder confirms the finishing of a menu point by flashing the front
lamp of the locomotive. Depending on which menu point you finish, it
flashes two, three or four times.
Reset
If you want to restore the data set in state of delivery you press the
analogue driving transformer direction switch and hold it there until the
light of the locomotive, after four flashes and a short break, starts to
flash quickly. Please note that a reset is performed on all locomotives
with this decoder type on the programming track.
If it is only the problem that a locomotive does not react on a certain
address or you have forgotten the address, you do not need to perform
a reset. As you do not have to enter the old address for programming
you can just programm the address as described in the section
"Programming the locomotive address".
Operation
Acceleration and brake delay
In Motorola II format the acceleration and brake delay is switched
alternately on or off by switching on the function F3. The change of the
setting takes effect immediately. If the acceleration and brake delay is
switched off during braking the locomotive immediately runs with the
speed level set at the central unit.
In Motorola I format the acceleration and brake delay is always active.
An emergency stop during acceleration and brake delay can be
performed from the central unit by changing the direction of travel.

English LD-G-3 / LD-W-3
Page 36
!
Switching the shunting gear
The shunting gear can be switched on and off via the auxiliary function
F4. In the shunting gear mode the velocity of all speed levels is reduced
to ca. 50 % compared to the standard velocity. The change of the
setting takes effect immediately.
In Motorola I format the shunting gear cannot be activated.
Improvement of the driving characteristics
Locomotives with especially high current consumption or track sections
with bad contacts (e.g. some types of points) may give an
unsatisfactory performance after the mounting of the locomotive
decoder. You can improve the locomotive performance by soldering a
capacitor 100 µF / >35 V to the points X1 and X7 (see fig. 1 and 2).
Analogue mode
In analogue mode the decoder can be run like a change-over switch. This
means the decoder reacts with a change of direction on the shift impulse
of the speed control knob, as usual. In analogue mode the lighting is
always switched on. It is switched depending on the direction of travel.
You access the analogue mode by pressing the direction switch of the
analogue driving transformer until the light of the locomotive starts flashing.
To get back into the digital mode, press the direction switch of the analogue
driving transformer again until the light of the locomotive starts to flash. Do
not hold the direction switch on too long, otherwise you perform a reset.
