2 Information SET-02

Important safety instructions

Do not leave your model railway system in operation when it
is not being supervised! If a short-circuit goes unnoticed, the
heat produced causes a risk of fire!

The LV200 is authorised for operation only with a UL or CE
approved transformer such as the Digital plus by Lenz ®, TR200,
the Aristo Craft ART-5460 10 amp transformer, or the LGB ­"Jumbo".

Care must be taken to not provide excessive voltage to the LV200
input. The LV200 is unlike any other power station produced. It
has very little loss and amplifies all the input voltage provided. If
you place a transformer greater than 16 volts AS or 23 volts
regulated DC you run the risk of providing a DCC track voltage in
excess of the 22 volts as specified in NMRA Standard S-9.1 which
could result in the damage of some decoders.

The heat produced by the power station in operation is normal.
You must provide sufficient air circulation around the power station
in order to prevent the internal protective system from reacting
prematurely, that is, during normal operation.

No radio interference suppression capacitor may be installed in the
track system. This capacitor is necessary only for the interference
suppression in conventional operation. If used with the
Digital plus by Lenz ® system, however, it would distort the data
format and interfere with the fault-free transmission of data.

A mixed digital operation using overhead lines and track is not
permitted. In such a mode of operation, if the locomotive is sitting
on the track in the wrong direction (which might be the case e.g.
after having driven through a terminal-loop), the installed locomotive
decoder can be destroyed by overvoltage! We recommend
operation using track pick-up, because the reliability of the
electrical contact (and therefore the transmission of digital signals
to the locomotive decoder) is substantially greater than it is when
operating with overhead lines.

2 Quick Start Users Guide

In this section you will learn about:

- the few steps that you need to know to operate your SET-02

- how to start your first test run

In the later sections below, the whole range of functions of the SET­02 will be explained in detail.

2.1 Connection and initial operation

1. Plug one side of the coil cable into the
socket of the LH200, and the other side
into the socket labelled I/O Port located
on the back of the LV200. This
connection must not be interrupted
during operation.

2. Connect terminals J and K of the LV200
power station to the tracks of your model
railway. You can pull off the green
terminal connector on the back of the
LV200. This will facilitate the installation
of cables. Make sure that no other
transformers or operating controllers are
connected to the tracks.

3. Connect terminals U and V of the LV200 to a model railway
transformer with a 13-16 VAC voltage. For initial operation
virtually any transformer with a current rating of greater than 13 VA
will work. To operate the maximum number of locomotives a
transformer with a minimum capacity of 10 Amps should be used.
See page 45 for more details on suitable transformers.

4. Put the locomotive which is equipped with the locomotive decoder
onto the track. (refer to the instructions that came with the
decoder for installation instructions)

5. Turn the rotary control-knob as far to the left
as possible and then flick the direction switch
into the horizontal / centre position (90° to
face of box). This is the stop position.

6. Plug the power cord of the transformer into a wall socket. The
display on the LH200 lights up and the red led on the LH200 turns
on solid red.

You can now start operating trains! (Yes, already!)

6 Information SET-02

2.2 Your first operation of a DCC train

Let us assume that the decoder which was delivered together with
SET-02 has been installed into your locomotive (either by you or by
someone else) and is now on your layout. This decoder is shipped
from the factory with address (number) 3. As shipped you can
immediately control locomotives with the addresses (numbers) 0 to

5. Address 0 is intended for a conventional locomotive, i.e. a

locomotive without an installed decoder.

A

Press the key "A" key repeatedly until 3 is shown in the display.

Flick the direction switch into the upward
position (forward is up)

Turn the rotary control-knob to the right.
The locomotive moves forward, and the
more you turn the knob to the right, the
faster the locomotive will move (Throttle
positions increase in size).

Turn the rotary control-knob back to the
left. The locomotive slows down, the
further you turn the knob to the left the
more it will slow down (Throttle positions
decrease in size).

Turn the knob as far to the left as possible: the locomotive stops.

Flick the direction-switch switch
downwards through the centre position.
This will change the direction of motion
of the locomotive from forwards to
backwards.

You can now move the locomotive in the opposite direction by using the rotary
control-knob as described above.

If you flick the direction-switch
switch to the centre position while
the locomotive is in operation,
the locomotive will stop with the

amount
of delay in braking which is set in the locomotive decoder. If you then flick the
switch in a different direction –without altering the position of the rotary control­knob-, the locomotive will speed up again, also with the amount of delay that is set
in the decoder.

M

In order to switch on the light function of the locomotive decoder, press
the key "0M". Press the key once and you will turn on the light, press it
again and you will turn it off. With LH200 you can control up to 9
functions in locomotive decoders.

You have just learned the most important things that you need to
know for the general operation of your digital controlled model
railway. In the next section you will learn about further functions that
your SET-02 has to offer.

3 SET-02 Capabilities Overview

In this section you will learn :

- the range of functions of SET-02

- the possibilities which this range of SET-02 functions opens up

to you in controlling your model railway

The use of the SET-02 functions is explained in detail at the end of
this section.

In SET-02 the LH200 Knob based Engineer's Throttle works
as both an input device and command station at the same
time. It produces the track format, which is amplified by the
power station (LV200) and sent to the tracks. This is why the
LH200 has to be connected to LV200 at all times during
operation.

3.1 Range of possible addresses for your locomotives

With SET-02 you may control any 4 digit locomotive address. This
means that a locomotive address can have any value from 1 to

9999.
Address 0 is special. With address 0 you control a non-decoder

equipped conventional locomotive on your DCC layout. Using a
conventional locomotive (a locomotive without decoder) and a digital
locomotive (with the decoder included with this SET) you are
immediately in the position to starting digital operation with two
locomotives!

You will find more information about selecting the locomotive you
wish to control from the LH200 in the section which starts on
page 14.

8 Information SET-02

3.2 Locomotive functions that can be controlled

You can address up to 9 functions in locomotive decoders (termed
F0-F8). You will learn how to switch these functions on and off in the
section "Switching locomotive-decoder functions on and off " which
starts on page 18.

3.3 Throttle Notch choices

Within DCC operations there is a concept of speed steps. Speed
steps refer to the number of throttle notches a locomotive decoder
can apply to the motor. SET-02 supports the choice of 14, 28 and
128 throttle positions. The default for all locomotives on the system
is 28 throttle positions. For information on how to select the various
modes and how to adapt them to your locomotive decoder, please
see the section "Matching the LH200s Throttle Notches to the
Decoders Speed Steps" which starts on page 19.

3.4 Multi unit (MU) consisting

Using Multi Unit control (in Europe called Multi Traction), you can
simultaneously control multiple locomotives via a common address,
the multi unit address (MU-address). You will feel as if you are
only controlling a single locomotive, but all locomotives in the MU
react simultaneously. Locomotives can be set up head to head or
head to tail and they still work properly together in this mode.

SET-02 remembers a lot of information about multi units even
between operating sessions. With SET-02 you can configure a
maximum of 24 locomotives in 12 multiple multi unit consists.

You will find detailed information on the assembly and controlling of
an MU in the section "Multiple Unit (MU) Consisting" which starts
on page 28.

3.5 Configuring decoder features

Decoders can be configured by the user to customize the behaviour
of a particular locomotive. The address of a locomotive decoder is an
example of a decoder feature that the user must set for each
decoder used. The variable starting voltage, acceleration rate and
braking rate are among the optional features of a locomotive
decoder, that can be customized. Decoder features can be altered
through a process called programming. SET-02 has made
programming as transparent to the user as possible. Two different
modes are supported.

Information SET-02 9

DIGITAL plus

Programming on the programming track
A programming track is an section of track that is completely

electrically isolated from the remainder of your layout. One decoder
at a time can be placed on this isolated track for setting the various
decoder configurations. For advanced decoders, only the locomotive
address needs to be set using this programming mode. You will find
information on this procedure in the section "Programming on the
programming track" which starts on page 35.

Programming while your locomotive is on your layout
For advanced decoders that support this feature, you can program

all the optional features of a locomotive decoder (except its address)
while the locomotive is on your DCC layout. For example, move your
locomotive to the front of a heavy freight-train and then adjust the
acceleration and breaking rate to suit the train! You will find more
detailed information in the section "Programming on the main –
POM" which starts on page 21.

3.6 Power Station capabilities

The power station, LV200, which is part of SET-02 can provide a
maximum current output of 10 amps. Depending on the demand for
current of the locomotives in operation, this is sufficient for 8 –12
large scale locomotives. If the capacity of a single LV200 power
station is not sufficient, you can add additional power stations. You
will find information on such expansion in the section "More power
through more power stations", which starts on page 42.

3.7 Expanding your system

You can connect up to 5 additional devices, such as additional
handhelds, to your SET-02. Which of the devices you decide to
choose from the Digital plus family is entirely up to you.

Examples:

Additional LH200s may be added for a more engineers.
Additional LH100 keypad based dispatchers throttles may be
added for operating locomotives or for switching turnouts or
signals.
A tower cab LW100 may be added to switch not only individual
turnout but entire turnout systems.
The computer interface, LI100, may be added to control your
model railway from your PC.

More detailed information on this can be found in the section
"Adding an X-Bus to allow additional input Devices" which starts on
page 40.

10 Information SET-02

3.8 Controlling turnouts

Although the possibilities opened through SET-02 features are many
and varied, SET-02 does have some limits. The LH200 contained in
SET-02 is not able to control turnouts or switch magnetic articles on
and off. This capability was omitted to keep the LH200 easy for a
train operator. Should you desire to be able to control turnouts or
other similar devices this can be achieved easily by connecting an
LH100 or a similar X-Bus device which contains these capabilities.
More detailed information on this can be found in the section
"Special information on operating X-Bus devices " which starts on
page 41.

3.9 Expanding beyond SET-02

SET-02 is part of our overall DIGITAL plus family. Should you ever
need more capabilities, (such as the ability to use more handhelds
or layout feedback) you can upgrade a SET-02 to our full
professional series by installing an LZ100 command station. When
the LZ100 is installed it becomes the command station and the
LH200, used as a command station in SET-02, becomes an
additional handheld for use anywhere on the installed X-Bus.

Gathering feedback about the switching of turnouts or the
occupation of track sections is possible only when SET-02 is
upgraded with the command station LZ100 . You will find more
information on this in the section Expanding beyond the capabilities
of SET-02 using an LZ100 Command Station" which starts on page

43.

4 Overview of the LH200 Operational Controls

In this section you will learn about:

- the information that is displayed in the LH200 LED display

- how to use the LH200 knob based Engineer's Throttle

- how to use the direction switch

- what the LH200 keys are used for

4.1 The LED display

LH200 has a luminescent, 4-digit LED-display. Each digit is able to
display the numbers 0 to 9.

In this operating manual the display is presented as follows:

Information SET-02 11

DIGITAL plus

In normal operation the address of the locomotive
which you are presently controlling is constantly
shown.

Points below left, in the centre and below right are
helpful for adjusting the rotary control-knob and the
direction switch when you take control of a different
locomotive. Diverging positions of rotary control-knob
and direction switch are indicated by flashing lights.
You will find more detailed information in later
sections.

4.2 The rotary control-knob

The black line on the rotary control-knob shows the actual speed.
Turn it to the right and you increase the throttle position (locomotive

speeds up), turn it to the left and you decrease the throttle position
(locomotive slows down).

Since the rotary control-knob has a stop-limit to the right and to the
left, you will know when you have reached the maximum speed or
come to a complete stand-still without having to look at your
handheld.

4.3 The direction switch

The direction switch has 3 positions:

Switch up: locomotive
moves forward

Switch to center:
locomotive stops. Turning
the rotary control-knob
knob does not influence
the locomotive's speed.

Switch down: locomotive
moves backwards

12 Information SET-02

4.4 The keys

Only a few well arranged keys are necessary for the controlling of
your locomotives:

The allocation is shown on the LH200: with
key 4 you choose the first digit on the right,
with key 3 the second digit from the right up
to key 1 which will then choose the fourth
digit from the right.

To use function numbers 5-8 first press the
"Shift" and then the number.

Emergency stop. This key has a variety of uses and effects. For
example, switching off the voltage on the track, stopping all
locomotives, stopping the locomotive indicated, or entering programming
track mode. This will be described below.

5 Emergency Stop

If you want to immediately stop

operation press the key.

The voltage on the track will be switched off, and all locomotives
stop immediately. During an emergency stop, the LED of the power
station LV200 flashes, and in the LH200 display flashes.

To resume operation, press the key again.
If you are within a menu when the key is pressed, the menu will

close down. If you desire, you can alter the function of this key.

6.1 Entering numeric values within a menu

To enter numeric values within a menu, always follow the same
procedure: Choose the relevant digit with the appropriate key and
alter the value by turning the knob. This procedure is described in
more detail in the following section.

7 Selecting the Locomotive you wish to Control

In this section you will learn about:

- how to scroll through the stack to select a new locomotive

address

- how to enter a new locomotive address into the LH200

Before controlling a locomotive, its address must first be selected.
There are two ways of selecting a locomotive address other than the
one that is currently displayed. Either you scroll through the stack
until the desired address is displayed or, if the address is not yet
present in the stack, enter a different address in the stack replacing
the one that is currently displayed.

7.1 Scrolling through the stack

The stack facilitates quick access to up to 6 locomotive addresses.
Each entry in the stack can contain any locomotive address
between 0 and 9999. This will ensure you have fast and reliable
access to the locomotives, which are most important for the current
operating session at the touch of a few buttons. When shipped, the
locomotive addresses 0 through 5 are the default values in the
stack.

A

When pressed this key switches over to the next
locomotive address in the stack, and the address is shown
in the display. Having reached the top of the list, the
following key stroke will again display the digit address at
the bottom of the list.

7.2 Entering a new locomotive address into the LH200 stack

From the factory the locomotive addresses 0 through 5 are stored in
the stack. If you want to enter a different address in one of the 6
entries of the stack lists, scroll through the stack until an address is
displayed that you want to overwrite. In DCC there is a concept of a
short (2 digit) address and a long(4digit) address. The LH200
makes this transparent to the user. Simply enter the address you
desire and the LH200 does all the work for you.

Information SET-02 15

DIGITAL plus

Example 1: entering a 2-digit digit address

In the following example the current address "03" in the stack is
changed to "46". The locomotive with the address 3 will remain
running on the layout with the LH200 knob position that was present
before the menu option was selected. In the following the user
action is on the left and the display results are on the right.

First you select the address menu:

+

0

M

Go to the menu "Enter a new
digit address into the stack"

Now confirm the address menu selection with the "A" key:

A

Now the entire right digit of the address
(the ones digit) flashes on the display.

Alter the value of this digit by turning the
rotary control-knob to the right (value
increases) or to the left (value decreases).
In this example the value is altered to 6.

3

7

Now select the 10s digit. The value 6 is
now valid as the ones digit and the 10s
digit begins to flash.

Turn the rotary control-knob until the
desired value is shown and conclude the
input with key "A" key.

A

The new selected locomotive can now be
controlled by the LH200. You can now
adjust the positioning of the rotary control­knob and the direction switch as described
above.

Example 2: entering a 4-digit address

In this example the address 46 in the stack is replaced by the
address 1234.

First we enter the address menu:

+

0

M

Go to menu " Enter a new
locomotive address into the
stack"

Now confirm the address menu selection with the "A" key:

16 Information SET-02

A

The furthest right digit of the address
display now flashes.

Alter the value of this digit by turning the
rotary control-knob to the right (value
increases) or to the left (value
decreases). In this example the value is
altered to 4.

3

7

Now select the next digit you desire to
alter. The value 4 is now valid as the ones
digit and the 10s begins to flash.

Turn the rotary control-knob until the
desired value is shown.

2

6

If a 4-digit number locomotive is desired,
pressing either the "1" or "2" key extends
the display 2 more digits. If the "2" key is
pressed, the third digit from the right
flashes.

Turn the rotary control-knob until the
desired value for the second digit from the
left is shown, here 2.

1

5

Pressing the "1" key causes the left hand
digit to flash indicating that this is the digit
you desire to change.

Again the value is altered, in this example
it is altered to 1. End with "A" key to
complete the final take over of the
address.

A

Now adjust the position of the rotary
control-knob and the direction switch as
described above.

Until you press the check key (the "A  " key), which indicates that
your selection is complete, you can switch back and fourth between
the individual digits as often as you like by pressing keys 1 through
4 until the desired address is correctly displayed on the LH200
display.

Advice:
All 4 digits of the display do not have to be altered. If certain digits

already have the correct value, you can leave them as they are and
go to the next digit.

Information SET-02 17

DIGITAL plus

Example:

8 Operating a Locomotive with your LH200

In this section you will learn about:

- how the rotary control-knob and the direction switch are used to

match the speed of an operating locomotive

- how to control the locomotives functions

Once you have selected desired locomotive address and this
address is in the LH200 display, it is possible to control the
locomotive.

If the direction switch is correct, you can immediately take
over the displayed locomotive address by moving the rotary
control-knob. If the direction switch is in the wrong position
you must first move the direction switch to the correct
position. You will know that this is the case when one of the
dots in the centre stops flashing.

Dot is not flashing:

direction switch is in correct position.

Take over the locomotive by turning the

rotary control-knob.

Dot is flashing:

direction switch is in wrong position. In

order to take locomotive over, simply

change the direction-switch.

Such actions might result in a change the speed of the locomotive.
It is better to adjust the position of the rotary control-knob in the
manner described in the following section.

8.1 Adjusting the rotary control-knob position to the speed

of the selected locomotive

After you have selected the desired address, and in order to adjust
the rotary control-knob to the current speed, move the direction
switch to the centre position. This is only necessary if a difference
between the LH200 knob speed and the current locomotive speed
are different. The display will indicate in which direction you need to
move the rotary control-knob to correct for this difference:

Now place the direction switch in the correct position, up (forwards)
or down (backwards). If the upper dot appears in the middle of the
display, then you must move the switch up (the forwards position). If
the lower dot appears in the middle of the display you must move
the switch down switch it down (the backwards position backwards).

8.2 Switching the locomotive decoder functions on and off

The LH200 can control up to 9 locomotive decoder functions. To
control these functions the locomotive must first be wired so that the
desired function works. Activating a function which is not supported
by the locomotive decoder will have no effect.

The functions 0 through 4 can be switched on and off by pressing
the function key once.

Of course these functions can only be used, if the decoder installed
in the locomotive has the corresponding function outputs and if
these outputs are connected to a locomotive function (lighting,
smoke generator, coupling and so on).

9 Matching the LH200's Throttle Notches to the

Decoder's Speed Steps

In this section you will learn:

- what throttle notches and speed steps are

- which throttle notch modes you can select

- how you can use the LH200 to match the number of throttle

notches to a specific locomotive address

The range from a stop to the maximum speed of a locomotive is
divided into throttle notches. In the prototype locomotive there is
only a need for a very limited number of throttle notches. For our
models we often want much smoother operation than offered in the
prototype. The more precisely the speed can be controlled, (that is
the more steps up or down in speed that the whole range can be
divided into) the greater the number of throttle notches that are
needed. The LH200 rotary control knob has 256 different throttle
positions to provide the maximum smoothness in operation.

DCC decoders support a variety of speed step modes. The most
common are 14, 28, and 128. Speed step modes reflect the
number of throttle notches that the decoder will support. SET-02
supports all three of these speed step modes. Since different
commands are sent to the decoder in all three modes it is
necessary to match the number of LH200 throttle notches to the
