GOLD Decoder feature set
The following contains a short introduction of the features of the GOLD decoder as well
as information on how to use them.
For more detailed information please refer to the "GOLD decoder" information which
can be downloaded from the Lenz Elektronik GmbH website: www.lenz.com.
Capacity and protection equipment
The motor output has a current-carrying capacity of up to 3 amps without any concern
for cooling! The short-term maximum current-carrying capacity is 5 amps. The decoder
is protected against overloading, short circuits and overheating. In case of a fault, a bit
is set in CV30 which will state the type of fault which has occurred. This bit can be
cleared via setting this CV to 0. Because of this protection the Gold decoder can work
with motors that have very high stall currents.
The total capacity of the decoder can be increased using a heatsink on the decoders
rectifier.

Important safety instructions
Digital plus locomotive decoders are designed to be used only with Lenz Digital plus or
other standard NMRA Digital Command Control system. For best performance we
recommend systems with an NMRA-conformance seal. If in doubt, ask the system
supplier.
Please note that the maximum current-carrying capacity of the outputs may not be
exceeded as this could damage the decoder! Under no circumstances may the parts
of the locomotive decoder be allowed to touch the metal components of the chassis or
the body of the locomotive as this could cause a short-circuit within the locomotive
decoder leading to damage.
Never wrap the locomotive decoder in insulating tape as this prevents the necessary
air circulation around the decoder. Instead, use insulating tape or something similar
around the metal components of the locomotive to avoid unintentional short-circuits
without depriving the decoder of air. Use double-sided adhesive-tape to affix the
decoder.
Locomotives equipped with Digital plus decoders must not be run using powered
overhead lines either on conventional DC control or DCC control systems as this could
subject the locomotive to double the voltage and damage the decoder.

Gold Maxi Locomotive decoder 3
The current-carrying capacities noted in the technical data above may not be
exceeded.
Before installing a Digital plus decoder, check the locomotive in normal DC operation
to ensure that it works correctly before modifying the locomotive.
Replace worn wheel contacts, motor brushes and blown bulbs. Only a locomotive that
is mechanically OK will function properly with a locomotive decoder.

Installing the GOLD decoder
Please note which motor connection is connected to the right rail pickups and which to
the left. If you do this, you will not have to try out which of the two motor outputs M1
and M2 of the decoder needs to be connected to which motor connection to set the
desired direction of travel. After removing the existing cables, the motor connections
must not be connected in any way to the chassis or the rail pickups of the locomotive.
Bear in mind that sometimes a connection like this is only made when the chassis is
put back! Please contact a service centre if you are in any doubt as to whether all
necessary preconditions for the installation are fulfilled!
First connect the decoder to the pickups of the locomotive:
•Input G1 to the right rail pickup
•Input G2 to the left rail pickup
Then connect the decoder to the motor connections:
•Motor output M1 to the motor output previously connected to the right rail pickup
•Motor output M2 to the motor output previously connected to the left rail pickup
Now, connect the function outputs as follows: N0te that the default function settings
can be changed using CVs 33-46. The following assume the default settings.
•Function output FA to the front lighting at the front in the direction of travel
•Function output FB to the front lighting at the back in the direction of travel

If a connection between the bulbs and chassis exists, the connection of the front
lighting is completed. If the bulbs are not electrically connected to the locomotive
chassis (we call this 'potential-free'), connect the other pole of the bulbs to the
connection U+ of the GOLD maxi (which of the U+ connections is irrelevant). If you do
this, the bulbs will shine somewhat brighter and the direction-dependent lighting will
also function in DC operation. The variant you choose depends on the design of the
locomotive.
When connecting LEDs, make sure that the connection U+ is the 'positive pole' (anode
side of the LED) and that the function output is the 'minus pole' (cathode side of the
LED). The voltage of the function output is 16 V. Do not forget the required voltage
multiplier.
Testing the installation
Place the locomotive on the programming track (without its housing) and read the
address. The decoder is programmed from the factory to the address 03. If you have
connected the decoder correctly thus far, you should now be able to read the address.
If you are not able to do so, it is possible that you have made a mistake when
connecting the cables. Do not subject the locomotive to full running track power
until you obtain the correct "03" address read-out. Check the cable connections
and change them as required. You should now be able to send your locomotive on ist
first test run on your layout.
Features of the GOLD maxi
The following contains a short survey of the features of the GOLD maxi as well as
information on how to set them.

For more detailed information please refer to the "Decoder operating manual"
which is available at your hobby shop or can be downloaded from the Lenz
Elektronik GmbH website: www.lenz-elektronik.de or www.lenz.com
Protection equipment
The decoder is protected against overloading, short circuits and overheating. In case
of a fault, the corresponding bit is set in CV30 which will state the type of fault which
has occured. This bit can be deleted via programming.
Motor control
The decoder has a high-frequency control (23kHz). To adapt it to the type of
locomotive used, you can choose between six different motor types in CV50. These
motor types include parameter sets which have been specially adapted to the
respective models. Moreover, it is possible to carry out fine-tuning via CV113 or CV114
when selecting motor types 4 or 5. Of course you can switch off both the high-
frequency drive as well as the control system itself. You can still use CV9 to adjust the
repeat rate. Note: The factory default is ideal for the vast majority of locomotives in
the market.
The minimum (CV2), maximum (CV5) and mid (CV6) speed can be set; the decoder
automatically adapts the characteristic speed line dynamically to ensure a steady,
smooth curve. Independently of this, it is also possible to program an individual
characteristic speed line.
The decoder still has a so-called EMF switch which makes it possible to adjust the
decoder to different motor types. Depending on the motor type used, it is possible that
a digitally controlled locomotive cannot reach an adequate maximum speed compared
to a locomotive in conventional operation. If this is the case, activate your EMF switch
by setting Bit 6 in CV 50. The locomotive will then reach a higher maximum speed
while the minimum speed is also slightly increased.
Speed Steps
The decoder can be operated in the 14/27 or the 28/128 speed step mode. This setting
is made in CV29.
Disabling of delay
Use function 4 (the factory default setting can be altered in CV60) to disable the
starting and braking delay as well as the constant braking distance during operation.
The delays are disabled as long as the function is active.
Constant braking distance
During the transition from the current speed step to speed step 0 (e.g. by rotating the
knob of the LH90 handheld to the left limit-stop), the locomotive/train covers a settable,

Gold Maxi Locomotive decoder 6
6
defined braking distance. This braking distance does not depend on the speed of the
locomotive/train.
Setting the constant braking distance:
The braking distance is defined by the value set in CV52. Since the motors and gear
ratios of locomotives vary, the braking distance differs from locomotive to locomotive
even if the same value is set in CV52.
1. Use a short test section to measure how long your locomotive’s braking distance
will be with a given value set in CV52. Start with the default value (100) in CV52.
2. Enable the constant braking distance function (this requires setting Bit 2 in CV50.
If this bit is not set, the decoder will use the speed-dependent braking delay).
3. Accelerate your locomotive until it has reached average speed.
4. At a chosen point in time, set the running notch to 0. This requires moving the
turning-knob of the manual controls LH30, LH90 or the compact to the left limit-
stop; if you are using the LH100, keep pressing the key until the running notch is
set to 0 or until the locomotive address is displayed (if using the LH100, do not
press key ! This results in a locomotive-specific emergency stop and the
delays in the locomotive decoder will not be enabled!).
5. Measure the covered braking distance.
6. Increase or decrease the value in CV52, e.g. in steps of 10, and carry out another
measurement. You will thus create a table which will show the braking distances in
relation to the values set in CV52.
Important braking distance advice:
The constant braking distance is only effective if the running notch is altered to 0. If the
running notch is decreased from e.g. 28 to 10, the speed-dependent delay from CV4
becomes effective.
While the shunting speed is switched off (default setting F3), the constant braking
distance is disabled and the delay from CV4 becomes effective.
The constant braking distance is also disabled if the delays set in the decoder are
disabled by means of the corresponding function.
The two latter features can also be used sensibly if you wish to interrupt a current
braking process prematurely.
The constant braking distance does not work if the layout is operated in analogue DC
mode.
Shunting speed
The shunting speed halves the speed. This facilitates particularly sensitive control of
the shunting process. Use function 3 (From the factory setting, can be altered in CV59)
to enable and disable the shunting speed. If the shunting speed is enabled, the

Gold Maxi Locomotive decoder 7
constant braking distance is disabled. The shunting speed is enabled as long as the
function is active.
ABC = simple signal stop and slow approach
You can carry out a particularly simple signal stop using the ABC braking module.
Depending on the signal position, this module creates an asymmetric track voltage in
the braking section in front of the signal. The decoder reacts to this. Combined with the
constant braking distance, precise on-the-spot stopping in front of red signals is not a
problem. Of course, passage in the opposite direction is also possible. The signal
indication "slow approach/caution" does not pose a problem; the respective speed can
be set in CV53.
You can operate all functions during the signal stop or slow approach – you can even
reverse away again from the red signal! These special ABC modules can be used to
assemble a very simple block section. Activate the ABC module by setting Bit 2 (1) in
CV51.
The ABC feature is not active whenever the shunting speed is switched on or the delay
is disabled.
Push-pull train control
A push-pull train control can be set if the ABC braking module is used. There are two
different options: push-pull operation with and without intermediate stops. The latter
also takes slow-approach sections into account.
The push-pull train control is activated in CV51, Bit 4 (3) and Bit 5 (4). The stopping
time at the end of the track is set in CV54 (1 to 255 sec).
Allocating function outputs to the functions of the digital system (mapping)
You can define which digital function is used to switch function outputs FA to FH on or
off. Outputs FA to FC can be mapped to function F0 (direction-dependent) or functions
F1 to F8. Outputs FD and FE can be mapped to function F0 (direction-dependent) or
functions F1 to F12. Outputs FF to FH can be mapped to functions F4 to F12.
This is allocated in CVs 33 to 46.
Lighting effect at function outputs
The lighting effect for the function outputs A and B is set in CV60 and for the function
outputs C and D in CV62. If you wish to switch the effects with a function of the digital
system, you can make the allocations to functions F1 to F8 in CV61 (for function
outputs A and B) and CV64 (for function outputs C and D). The effects available are
shown in the table of the supported CVs further below.

RailCom
The GOLD maxi is equipped with the RailCom function. In addition to the locomotive
address, other data (e.g. speed, CV content) can be transmitted from the locomotive
via the track back to the system. The information sent is received by a RailCom
detector and then displayed. Which data the decoder is to send is set in CV28. Set Bit
4 in CV29 to enable the transmission function.
The S.U.S.I. interface
The sound and function interface concept for locomotive decoders was devised in
2002 in cooperation with the company DIETZ. The purpose of the interface is to
facilitate the particularly easy connection of sound and other function modules to
locomotive decoders.
The S.U.S.I. module receives information about the running notch, the status of the
functions etc. via the interface and reacts accordingly, for example the sound of a bell
is played or the locomotive sound changes.
The quality of these sound effects depends solely on the S.U.S.I. module and not on
the locomotive decoder!
Connecting a S.U.S.I. module
You may connect all sound and/or function modules to the S.U.S.I. interface that
correspond to the interface's specification. There is a socket for the connection of a
sound or function module – use it to plug in a suitable S.U.S.I (Abb.3, p 6).
Setting (programming) the S.U.S.I. module
Like locomotive decoders, there are also various ways of setting S.U.S.I. modules.
These settings are also saved in configuration variables (CVs). If you wish to change
these CVs, proceed as if you wanted to change the CVs of the locomotive decoder.
The S.U.S.I. module is programmed "through the decoder" as it were. Based on the
number of the CV, the locomotive decoder will know whether the S.U.S.I. module is to
be addressed and will transmit the programming commands via the S.U.S.I. module.
Please refer to the operating manual of your module to learn about the settings
possible for your S.U.S.I. module.
The settings of the S.U.S.I. module can be carried out both through "Programming in
operational mode (PoM)" or "Programming on the programming track". When using
Digital plus by Lenz ®systems, you can change CVs 1 to 999 with PoM, while
"Programming on the programming track" is currently used for CVs 1 to 256. CVs 897
to 1024 have been defined for the S.U.S.I. module. A special programming method
has been built into this decoder so that these CVs can be reached.
In this programming method, CV126 functions as an indicator and CV127 as a
transport device for the value.

Gold Maxi Locomotive decoder 9
The function sequence is as follows: The target (number of the CV) is entered in the
indicator CV126, and the value that is to be transported to the target is entered in the
transport device CV127. If you only wish to read out the target CV, the transport device
CV127 is read out after the target is entered in CV126.
Since only values up to 255 can be entered in a CV, but the CVs for S.U.S.I. start at
897, the CV that functions as the indicator is preset to 800. All you have to do is enter
the difference between 800 and the desired target CV, for example number 97 for the
target CV897.
Example 1: You wish to enter the value 01 in CV897 of the S.U.S.I. module. Proceed
as follows:
1. Enter 897-800=97 in the indicator CV126.
2. Enter the desired value "01" in the transport device CV127. The decoder passes
the programming command "Enter value "01" in CV "897"" via the S.U.S.I. interface
to the connected module.
Example 2: You wish to read out the present value of CV902 of the S.U.S.I. module:
1. Enter 902-800=102 in the indicator CV126.
2. Read out the transport device CV127. The value of CV902 of the connected
module is displayed.

USP – Uninterruptable Signal Processing
In combination with the optional energy storage, the intelligent USP circuit ensures that
your locomotive can run even over dirty track sections or dead frogs. The energy
storage is not included with this decoder and is installed separately in the vehicle.
Three terminal screws are provided on the decoder for the connection of the energy
storage (e.g. Power 1) or a battery circuit.

Signal stop and push-pull control with an external reed contact
The GOLD Maxi has a connection for an external reed contact. The reed contact is
installed at the bottom of the locomotive. You can let your locomotive stop in front of a
signal or operate in push-pull operation with the help of a magnet installed in the track.
Please see Fig. 4, p. 7 for the connection of the reed contact.
Signal stop
To activate the signal stop via the external reed contact, set bit 7 in CV51.
Function sequence: If the locomotive drives over the magnet installed in the track (reed
contact is closed), the locomotive will brake with the delay set in CV4 or the braking
distance set in CV52 until it comes to a halt. When the locomotive is to accelerate
again, set the speed to speed step 0 and accelerate.
Emergency stop: If a locomotive drives over a second magnet while braking (contact is
closed again), it will stop immediately, i.e. without the set delay (or braking distance).
This feature can be used as a kind of 'INDUSI' by using an electronic magnet as
second magnet which is only active when the corresponding signal indicates 'stop'.
Push-pull (shuttle) train control
To activate the push-pull control via the external reed contact, set bits 7 and 8 in
CV51. In addition, set the desired stopping time in CV54. You need a track magnet to
activate the reed contact at each end of the push-pull section.
Function sequence: If the locomotive drives over the magnet installed in the track (reed
contact is closed), the locomotive will brake with the delay set in CV4 or the braking
distance set in CV52 until it comes to a halt. When the stopping time set in CV54 has
elapsed, the locomotive will accelerate into the opposite direction. Passage over the
first magnet (which triggered the braking procedure) is ignored. The locomotive will
continue until it reaches the magnet at the end of the push-pull section. There, the
locomotive will brake again, wait for the set stopping time to elapse, change ist
direction of travel, and continue in this direction – and the game starts all over again.
Programming the decoder
The locomotive address, acceleration and deceleration delay, and all other features of
the locomotive decoder can be changed as often as desired by reprogramming the
decoder. The features are "stored" permanently in special locations even when the
operational voltage is switched off. These locations are called "configuration variables"
or simply "CV". The values are configured electronically, which means that it is not
necessary to open the locomotive again after the decoder has been installed.
The Gold Maxi decoder supports all forms of NMRA defined service mode
programming. To program a Gold Maxi decoder you will need a system capable of

Gold Maxi Locomotive decoder 11
service mode programming (such as Set-90 or Set-100). Please note that not all
systems support the programming of all CVs.
You can also alter the content of CVs both through "Programming in operational mode
(PoM)" (except for CV1, CV17 and CV18) or "Programming on the programming
track".
For detailed instructions on how to program using the above-mentioned devices,
please refer to the operating manuals which accompany those devices.
The factory default for the decoders address is address 3 running in 28 speed step
mode. The decoder can be used with these basic configurations immediately after
purchase. All configurations can, of course, be changed at any later date.
Resetting the decoder
If you wish to reset all the decoder CVs to the factory default setting, enter value 33 or
a value of 8 in CV8. The CVs of a connected S.U.S.I. module are not reset!
