a permanent magnet (e.g. item no. 70-04100, 70-04200 or 70-
04300) or
a motor modification set (e.g. item no. 70-40110, 70-40210 or 70-
40310).
In order to bridge short current interruptions you need:
an electrolytic capacitor with a capacity of 100 to 470 µF and a
proof voltage of minimum 35 V.
2. Safety instructions
Caution:
Integrated circuits (ICs) are inserted on the decoder. They are
sensitive to static electricity. Do not touch components without first
discharging yourself. Touching a radiator or other grounded metal part
will discharge you.
Mechanical hazards
Cut wires can have sharp ends and can cause serious injuries. Watch
out for sharp edges when you pick up the PCB.
Visibly damaged parts can cause unpredictable danger. Do not use
damaged parts: recycle and replace them with new ones.

LD-G-32.2 and LD-W-32.2 English
Electrical hazards
Touching powered, live components,
touching conducting components which are live due to malfunction,
short circuits and connecting the circuit to another voltage than
specified,
impermissibly high humidity and condensation build up
can cause serious injury due to electrical shock. Take the following
precautions to prevent this danger:
Never perform wiring on a powered module.
Assembling and mounting the kit should only be done in closed,
clean, dry rooms. Beware of humidity.
Only use low power for this module as described in this manual and
only use certified transformers.
Connect transformers and soldering irons only in approved mains
sockets installed by an authorised electrician.
Observe cable diameter requirements.
After condensation build up, allow a minimum of 2 hours for dispersion.
Use only original spare parts if you have to repair the kit or the
ready-built module.
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.

English LD-G-32.2 and LD-W-32.2
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 kit or the ready-built
module.
Caution:
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 must be
supervised by qualified personnel.
In industrial institutions, health and safety regulations applying to
electronic work must be adhered to.

3. Safe and correct soldering
Caution:
Incorrect soldering can cause dangers through fires and heat. Avoid
these dangers by reading and following the directions given in the
chapter Safety instructions.
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.
Only use electronic tin solder with flux.
When soldering electronic circuits never use soldering-water or
soldering grease. They contain acids that can corrode components
and copper tracks.
Solder quickly: holding the iron on the joints longer than necessary can
destroy components and can damage copper tracks or soldering eyes.
Apply the soldering tip to the soldering spot in such a way that the
wire and the soldering eye 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 solder flows into the joint, then remove the
soldering iron.
The joint should be held still for about 5 seconds after soldering.
To make a good soldering joint you should 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.
After soldering check (preferably with a magnifying glass) tracks for
accidental solder bridges and short circuits. This would cause faulty
operation or, in the worst case, permanent damage. You can remove
excess solder by putting a clean soldering tip on the spot. The solder
will become liquid again and flow from the soldering spot to the
soldering tip.

4. Operation overview
4.1. Modes of operation
Digital operation
The locomotive decoder is a multiple protocol decoder, that can operate
with and automatically recognise both DCC or Motorola formats.
The number of addresses is dependant on the format being used:
Motorola-Format: 255 addresses,
DCC-Format: 127 Basis-addresses or 10.239 extended addresses.
In the DCC format the decoder can be driven in all speed levels (14, 28
or 128). In the Motorola format the decoder can be driven in 14 or 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 allow 14 speed levels only, it is only possible to select every
second speed level.
Programming the decoders is done:
in Motorola format by setting the registers,
in DCC format by setting the configuration variables (direct
programming, DCC conform) or by POM (programming on main =
main track programming).

LD-G-32.2 and LD-W-32.2 English
Analogue mode
The locomotive decoder can also be used in analogue model railway
layouts run with a D.C. speed control, and with restrictions with an A.C.
speed control. When putting the vehicle 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.
Caution:
Old analogue driving transformers (e.g. models in a blue housing
from Märklin**) are not suitable for use with digital decoders in
analogue operation! These transformers have been designed for the
older supply voltage of 220 V and, due to construction, generate very
high excess voltage impulses when changing the driving direction.
When using them with the modern supply voltage of 230 V too high
excess voltage impulses can occur, damaging electronic parts on the
decoder. For that reason only use driving transformers designed for a
net voltage of 230 V.
Switching the function outputs on or off is not possible in analogue
mode. They can be programmed so that they are either switched on or
off in analogue mode. The effects set for the outputs are active in
analogue mode as well.
Outputs to be switched with F0 are switched on or off in analogue mode
according to the direction of travel. When operated in analogue d.c.
layouts this applies only to lamps or accessories where the return
conductor is connected to the decoder´s common return conductor for all
function outputs.
The decoders´ load control is not active in analogue mode.

4.2. Driving of the motor
Pulse width modulation
The different decoder types are designed to optimally control their
particular fitting motor types.

PWM Suitable for coreless
(Faulhaber) motors
LD-G-32.2
32 kHz (fixed) yes
LD-W-32.2 480 or 60 Hz (to be set) no
Load control
The LD-G-32.2 for DC motors has a load control, the LD-W-32.2 for AC
motors do not have this function.
The load control influences the motor voltage to keep the locomotive
with a set speed level at constant velocity, independent of additional
loads (e.g. running up a gradient, coupled carriages).
It is possible to switch on and off the load control by varying a CVvariable of the decoder. The parameters of the load control may be
altered, in order to adapt the decoder to the motor´s individual
characteristics.
Parameters of the load control: The load control is determined by
three parameters which have to be coordinated in order to achieve
optimal driving characteristics. Each of the load control parameters is
assigned to a configuration variable. The parameters are:
KP: The proportional component of the load control ensures the
difference between the set and the present value being as small as
possible. It cannot have the value "0" at any time. This component
affects the basic speed. In case the set value is too small the
locomotive runs too slowly. In case the set value is too high the
locomotive stutters while moving.
Page 12
tams elektronik
LD-G-32.2 and LD-W-32.2 English
KI: The integral component of the load control ensures the remaining
difference between the set and the present value is reduced to 0 and so
for the correction of very small divergences. If the set value is too high
the locomotive stutters massively while moving.
KD: The differential component of the load control ensures that the
control is not converted too quickly. Is the set value to low then the
locomotive stutters. If the set value is too high, the locomotive rocks
while moving.
Velocity characteristic
The decoder can be adjusted to the driving characteristics of the motor
and the characteristic speed of the locomotive type, by setting the
starting and maximum velocity. From these two settings the decoder
generates a linear velocity characteristic.
When the speed level mode is set to 28 speed levels, it is possible to
assign any motor voltage to all of the 28 speed levels as an alternative
to the linear velocity characteristic. This allows the programming of a
velocity characteristic which adjusts the individual driving characteristics
of the motor. The set values are saved in the alternative velocity table.
Shunting gear
It is possible to switch into the shunting gear mode via a function key
(in state of delivery F3), when so programmed. In the shunting gear
mode, the velocity of all speed levels is reduced to approx. 50 %
compared to the set velocity.
Acceleration and brake delay
It is possible to program the acceleration and brake delay individually
via the central unit. When so programmed, it can be switched on and
off with a function key (in state of delivery F4).
Page 13
tams elektronik
English LD-G-32.2 and LD-W-32.2
Emergency stop
It is possible to carry out an emergeny stop at a change of direction
automatically, when so programmed.
4.3. Function outputs
The decoder has function outputs, which are available to connect
optional accessories (e.g. lighting, smoke generator, sound module,
electric coupling). The accessories´ number and type to be connected
depends on the outputs´number and maximum current as well as on
the maximum total current of the special decoder (see section 5
"Technical specifications").
Effects of the function outputs
It is possible to set the following effects for the function outputs
individually:
Switching on and off depending on the direction of travel.
Flashing and double flashing. Both the frequency and the keying
ratio can be set. E.g. single and double flash lights or strobe lights.
Dimming: Example of use: The electric bulbs of older vehicles made
for analogue operation can be dimmed and thus must not be
exchanged after the mounting of the decoder.
Shunting light: You can program the outputs so that they are switched on
generally during shunting operation (to be switched with F3 or F4). The
dependence on the direction of travel will be nullified for these outputs
during shunting operation.
Page 14
tams elektronik
LD-G-32.2 and LD-W-32.2 English
4.4. Releasing the functions
The function outputs can be released by pushing the function keys. The
mapping of the outputs to the function keys and the switching inputs is
arbritary. It is possible to assign several function keys and switching
inputs to one output.
Outputs DCC format MM format
AUX1 to AUX3 F0 to F12 F0 to F4 or
F5 to F9
(= F0 to F4 of a second
decoder address)
4.5. Automated processes
The control software in the locomotive decoder allows you to automate
procedures and to reduce complex processes to one keystroke.
Dimming depending on the velocity
You can automatically switch functions depending on the velocity when
reaching a speed level defined in a CV. You assign an individual voltage
to the function outputs for the ranges of speed levels underneath and
above the defined speed level. This allows for example to switch on and
off the high beam light, to control the cab light or to influence the
intensity of the steam output.
Shunting function
You can assign the shunting gear and the shunting light to the same funtion
key. That way you switch on the shunting light automatically when
switching into the shunting gear (and thus reducing the velocity).

4.6. Feedback with RailCom**
RailCom is a log for bi-directional communication in digital model
railway layouts controlled in DCC-format. It allows e.g. the feedback of
the address and the CV values from the decoder to the digital central
unit or to special receivers (so-called detectors). The decoders must be
designed to send the RailCom messages.
When so programmed, the locomotive decoders LD-G-32.2 and LD-W-
32.2 send (continuously) the (basic, extended or consist) address to the
detectors (so-called RailCom broadcast datagramm) and transfer a CV
message after a DCC CV read-out command.
Sending RailCom messages is only possible in layouts with a DCC signal
on the rails. It is not possible to use the RailCom-function in a pure
Motorola environment.

6. Connections
Note the following comment in order to protect the
decoder from (maybe irreparable) damage!
Avoid all conducting connections between the decoder and
accessories connected to the decoder´s common return conductor for
all function outputs on the one hand and metal parts of the vehicle or
the rails on the other hand. Connections result for example from badly
isolated connecting wires (as well at the stripped ends of connecting
wires not in use) or insufficient fixing and isolating the decoder or the
accessory, for example. Risk of short circuit! In this case the overload
protection of the decoder is not able to protect the decoder from
damage.
Before connecting the motor, lighting or other accessories check if
their current is below the maximum permissible values and the total
current is below the safe load. Should the permissible current be
exceeded, this can result in damage to the decoder.
You should under no circumstances connect the decoder´s common
return conductor for all function outputs to vehicle ground. Risk of
short circuit!
Old analogue driving transformers (e.g. models in a blue housing from
Märklin**) are not suitable for use with digital decoders in analogue
operation! These transformers have been designed for the older
supply voltage of 220 V and, due to construction, generate very high
excess voltage impulses when changing the driving direction. When
using them with the modern supply voltage of 230 V too high excess
voltage impulses can occur, damaging electronic parts on the
decoder. For that reason only use driving transformers designed for a
net voltage of 230 V.

6.3. Using decoders with interface connectors
Many recent locomotives with d.c. motor are equipped ex works with an
interface socket. Using a decoder with a suitable connector saves
separating the connections and soldering works at the locomotive.
Possible versions:
Description Number of poles MOROP standard
6 pole 6 NEM 651
8 pole 8 NEM 652
The interface enables you to connect the decoder to the motor, the rail
current collectors, the lighting and – provided the special connector is
designed for it – additional accessories.
When mounting decoders with 6-pole interface connectors according to
NEM 651 or 8-pole interface connectors according to NEM 652, take
care to put the markings on the connector and on the socket on top of
each other.
6.4. Use in locomotives with a.c. motor
The LD-G-32.2 has been designed to control direct current (d.c.)
motors, for that reason it cannot be connected directly to alternating
current (a.c.) motors. You can control a.c. motors with the LD-G-32.2
and benefit of the load control when
mounting a load control adapter between a.c. motor and decoder or
replacing the field coil of the a.c. motor by a permanent magnet.
Page 21
tams elektronik
!
English LD-G-32.2 and LD-W-32.2
6.5. Mounting decoders without interface
Locate the position for the decoder after opening the locomotive
housing. Disconnect the motor from the rail current collectors or 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 decoder to the motor
Connect the decoder to the rail current collectors and to the motor.
Should the locomotive´s direction of motion in analogue mode not
match the direction of motion set at the speed control you have to
swap the connections to the rail current collectors / the slider.

Connecting accessories to the outputs
Disconnect any existing diodes in the leads to the lamps, otherwise the
lamps might not light. Connect the lamps and the accessories to the
function outputs of the decoder. If the lamp or the accessory is already
connected with one side to vehicle ground, the connection is complete.
If not, connect the second side of the lamp or the accessory to the
decoder´s common return conductor for all function outputs.
You find the factory (default) settings in the lists with the connector pin
assignments. You can assign the outputs to the function keys
voluntarily by setting the configuration variables.

English LD-G-32.2 and LD-W-32.2
6.6. Connecting LEDs to the function outputs
The decoder´s function outputs switch respective to the decoder
ground. For that reason you must connect the cathodes (-) of the LEDs
to the function outputs and the anodes (+) to the decoder´s common
return conductor for all function outputs.
Caution:
If you use light-emitting diodes (LEDs) you must always operate them via
a series resistor, otherwise they will be damaged when put into operation
or their duration of life will be reduced considerably!
When doing without a series resistor, other components undertake the
series resistor´s function (e.g. rails, wheels, current connectors), possibly
leading to a modification of the data signal and thus to disturbances in
digital operation.
Always determine the necessary series resistor´s value for the peak
value of the available operating voltage. With regulated boosters this
corresponds to the specified boosters´ output (= track) voltage. With
not regulated boosters or analogue driving transformers the peak
value is approx. 1,4 fold the nominal voltage specified on the
transformer.
Serial connection of LEDs
When you want to connect several LEDs to one output you can switch them
in series via a common series resistor. The current consumption is max. 20
mA for all LEDs, depending on the series resistor´s value. The maximum
number of LEDs to be connected in series results from
Peak value of the operating voltage
- sum of the forward voltages of all LEDs
> 0
The advantage of this solution is the low current consumption.
In order to determine the necessary series resistor for a serial LED´s
Page 24
tams elektronik
LD-G-32.2 and LD-W-32.2 English
connection first add the forward voltages of all LEDs. The forward
voltages depend on the lighting colour and should be given in the
technical specifications. In case there is no manufacturer information
available, you can take as a basis 4 V for white and blue LEDs and 2 V
for yellow, orange, red and green LEDs.
The remaining voltage has to be "eliminated" by a resistor. The formula
for the calculation of the resistor is:
required RV [Ohm] = ( UB [V] – ∑ UF [V] ) / (IF [mA] x 0.001)
UB = operating voltage (peak value) | ∑ UF = sum of the forward voltages of all LEDs
IF = current with max. luminosity
Parallel connection of LEDs
Alternatively, you can connect several LEDs in parallel, each via a series
resistor of its own. The current consumption is max. 20 mA for all LEDs,
depending on the series resistor´s value. The maximum number of LEDs to
be connected in parallel results from
maximum current at the output
- sum of the current consumption of all LEDs
> 0
Advantageous with this solution is that the LEDs already lighten when
their forward voltage has been reached (2 to 4 V, depending on the
fluorescent colour), which makes this solution suitable for analogue
mode. Disadvantageous is the high current consumption.
The formula for the calculation of the resistor is:
required RV [Ohm] = ( UB [V] – UF [V] / (IF [mA] x 0.001)
UB = operating voltage (peak value) | UF = forward voltage of the LED
IF = current with max. luminosity
In order to save current, you can limit the LEDs´current consumption to
10 mA, which normally does not cause a visible loss of luminance.

6.7. Connecting inductive loads
When connecting inductive loads (e.g. TELEX couplings, relays or other
accessories with coils), you should switch a free-wheeling diode (e.g.
1N400x) in parallel, in order to avoid damage at the output. Check to
connect the anode of the diode to the function output.
6.8. Connecting accessories via a relay
When you want to switch an accessory / accessories via the decoder,
which connection would lead to exceeding the maximum current at the
output or of the decoder, you can switch the accessories via a relay
(e.g. 1xUm 1A 12V, item-no. 84-61010) and connect them directly to
the vehicle´s current collector.
The current consumed by the relay depends on its type. The relay named in
the example needs approx. 100 mA.
As described in the section "Connecting inductive loads" you should
switch a free-wheeling diode (e.g. 1N400x) in parallel to the relay.

6.9. Connecting a buffer capacitor
In sections with bad contact to the rails the power supply of the
decoder can be interrupted. Possible consequences are e.g. flickering
lighting. In these and similar cases you can find a remedy by
connecting a buffer capacitor.
The electrolytic capacitor should have a capacity of minimum 100 µF
and a proof voltage of minimum 35 V. Observe the correct polarity
when connecting the capacitor!
6.10. Fixing the decoder
After having finished all connections you should fix the decoder, to
avoid short circuits by contact to metal parts of the vehicle, for
example. You can use double sided adhesive tape for it or a decoder
holder (item no. 70-01810 or 70-01820), for example.

7. Programming
Programming with DCC central units
You can program the configuration variables (CV) of the decoder from
the digital central unit, you can use main track programming as well.
See the chapter in the manual of your central unit where the byte wise
programming of configuration variables (CVs) (Direct programming)
and main track programming (POM) are explained. With central units
that allow only register-programming it is only possible to program the
variables CV 1, CV 2, CV 3, CV 4 and CV 29 (= register 1 to 5).
Programming with Motorola central units
In Motorola format the settings are saved in registers.
Please note: If you use a central unit for both DCC and Motorola format
it is recommended to program the decoder in the DCC format. After
having finished programming the decoder it is possible to control it in
Motorola format as well.
Please note: You should connect a lamp or a LED to at least AUX1 or
AUX2 before starting to program the decoder with a Motorola central
unit, as the decoder shows the status of the programming by flashing
the lighting connected to these outputs. The flashing frequency shows,
which input the decoder expects:
Slow flashing Fast flashing
Number of the register to be
programmed
Value of the register to be
programmed
Put the vehicle on a track oval or a track section connected to the
central unit’s track output (not to the connection for the programming
track). Make sure no other vehicle than the one you intend to program
is set on the track as the decoder inside this vehicle might be
programmed as well.

3. Set all functions to "off".
4. Push button "stop"
à switch off the track voltage.
5. Operate the direction switch
and hold it in that position.
Push the button "go" at once.
6. As soon as the lighting
flashes, release the
direction switch.
1. Enter the number of the
register as a Motorola-address.
If necessary: with a leading "0".
2. Operate the direction switch.
à Lighting flashes faster.
3. Enter the value you want to
set into the register
(as Motorola-address).
4. Operate the direction switch.
à Lighting flashes more slowly.
Repeat steps 1 – 4
for all registers.
Push button "stop".
à Programming mode à End of programming mode.
Programming with Motorola central units with restricted input
options
Some central units do not allow but input values up to 80 or 99. With
the auxillary register 62 values above 80 can be entered.
Programming with the Central Station and the Mobile Station
With the Central Station I or the Mobile Station of Märklin** you can
program the registers. Select the article no. 29750 from the locomotive
database and program the decoder as described for this article in the
Central Station´s or Mobile Station´s manual.
Page 29
tams elektronik
English LD-G-32.2 and LD-W-32.2
Programming with the CV-Navi
Instead of programming the configuration variables or registers of the
decoder using the digital central unit, you can use the free software CVNavi. You will find the free download under:
www.tams-online.de
A central unit RedBox or Master Control is required for using the software.
8. Configuration variables and registers
The following lists shows all configuration variables (for the DCC
format) and registers (for the Motorola format), that can be set for the
locomotive decoders.
In the lists you will find in the column "CV-no." the numbers of the
configuration variables for programming in DCC format and in the
column "Rg.-no." the numbers of the registers for programming in
Motorola format. The defaults are those values set in the state of
delivery and after a reset.
Please note: With variables destined to set several parameters, the
input value has to be calculated by adding the numerical values
assigned to the desired parameters.

Optimising the CV-settings
Above all, the driving characteristics can be influenced by setting the CV
2 (starting voltage) and CV 5 (maximum voltage) and for the decoders
for d.c.motors (LD-G-32.2), in addition, by setting the CV 124
(optimizing the load control) and the CV 50 to 52 (parameters of the
load control).
Make the setting for the load controlled decoder LD-G-32.2 in the
following order, as far as required:
1. CV 124
2. CV 50 to 52
3. CV 2 and CV 5
To adjust the parameters for the load control (CV 50 to 52) the
following procedure is recommended:
If the locomotive is shuttering: à Increase the value for CV 52 (KD) in
5-steps. If this does not lead to an improvement of the driving
characteristics, set the value of CV 52 back to factory setting (default
value). Then decrease the value for CV 50 (KP) in 5-steps and for CV 51
(KI) in 2-steps.
If the locomotive does not have enough power and e.g. gets very slow
on the way uphill: à Increase the value for CV 51 (KI) in 2-steps, until
the locomotive starts to shutter. Then increase the value for CV 52 (KD)
in 5-steps. If this does not lead to an improvement or the locomotive
starts to shutter immediately after increasing CV 51, set the values for
CV 51 and CV 52 back to factory setting (default value) and increase
the value for CV 50 (KP) in 5-steps.
If the locomotive is rocking: à Decrease the value for CV 52 in 5steps.

9. Check list for troubleshooting
Parts are getting very hot and/or start to smoke.
Disconnect the system from the mains immediately!
Possible cause: one or more connections are soldered incorrectly.
à Check the connections.
Possible cause: Short circuit between the decoder or accessories
connected to the retrun conductor for all functions and metal parts
of the locomotive or the rails. à Check the connections. A short
circuit can result in irreparable damage.
Problems with the driving characteristics
After programming the decoder the locomotive does not run or runs
badly.
Possible cause: The set values for the CV are inconsistent.
à Perform a decoder reset and program the decoder anew.
In digital mode the locomotive suddenly runs very fast.
Possible cause: Interfering signals from the layout have switched the
decoder to analogue mode. à As the origin of the interfering signals´
often cannot be found, it is advisable to switch off the automatic
recognition of the analogue mode during digital operation.
The CV values cannot be read out by RailCom.
Possible cause: RailCom is switched off. à Alter the value of CV 29
(add "8" to the input value).
Problems in analogue mode
The locomotive does not run in analogue mode, the decoder does
not work.
Possible cause: The analogue mode is switched off. Alter the
value for CV 29.

Problems with switching of the functions
An accessory / a light does not react to switching commands.
Possible cause: The accessory is defective or incorrectly connected.
Check the accessory / the connections.
Possible cause: The output is defective (e.g. due to overload or short
circuit). Send in the decoder for check / repair (with costs).
The lighting goes on and off when the speed levels are turned up or
the lighting cannot be switched on or off.
Possible cause: The speed mode of the decoder and the digital control
unit do not correspond. Example: The central is set to the mode 28
speed levels, but the decoder to the mode 14 speed levels. Change
the speed mode at the central and / or at the decoder.
