1 Important information — Please read first!

Your LH100 hand held	controller	is a component of the
Digital plus by Lenz ® system	and was	subjected to intense testing

before shipping. Lenz Elektronik GmbH guarantees problem free operation when you follow these directions:

Depending on which command station (and which software version) you operate your LH100 on, certain functions are not or are only partially available. This manual contains all the possible LH100 capabilities present when used with an LZ100 V3. If you are using a different command control system, the LH100 capabilities may be reduced by the capabilities provided by that system. For details check out the system manual of the system you desire to use your LH100 on.

The LH100 must only be used with systems that have been branded to support XpressNet or the older X-Bus protocols. A branded system will display the XpressNet logo. Any other use than the one described in this operation manual is not allowed and will lead to voiding of the warranty.

Even when other devices (including ones from other manufacturers) have the same connectors, you may not operate the LH100 with these devices unless they display the XpressNet logo. Other systems may use the same connectors but have different internal wiring that can harm the LH100.

Do not expose the LH100 to moisture or extended direct sunlight.

) If you have problems,

please first check this operation manual to see if you may have missed a direction for use. The table of contents and especially the section “Troubleshooting” will help you here.

3 First steps

In this section you will find out how:

-to connect your LH100 to a LZ100 or a SET02 command station.

-to operate your first train

The following sections below will then explain all the functions of LH100 in detail.

3.1Connections and starting operation

The LH100 can be connected to any XpressNet system including the following components of the Digital plus by Lenz® system:

LZ100; SET02; SET03; Compact

It may also be used with other XpressNet systems including the Atlas Commander and the Roco Lokmaus 2 system.

)As with all XpressNet devices, you can disconnect your

LH100 during operation and reconnect it later when you wish. To make the maximum use of this advantage of XpressNet, install several connector plates LA152/LA153 or install 5 pin din plugs around your layout. You will then always be able to use the LH100 right at the desired place of action.

3.1.1 Connecting to command station LZ100

Insert the 5-pin DIN-connector

-in the 5-pin DIN-jack on the back of your LZ100

or, if you have already installed XpressNet (XBUS) wiring on your layout

-to a connector plate LA150, LA152, or 5 pin DIN plug

3.1.2Connecting to SET02 or Atlas Commander

Insert the 5-pin DIN-connector into a LA152/153 connection plate that is connected to SET02 or Atlas Commander, or to any other XpressNet 5 pin DIN plug.

3.1.3Setting the XpressNet - Address

All input devices connected to XpressNet (XBUS) must have their own unique device address for the information exchange to function correctly. You must therefore make sure that each connected device has its own unique address. Up to 31 devices can be connected to XpressNet, ie. you can program each device

LH100 Dispatcher’s Throttle

8

to addresses 1 through 31. Each hand held controller LH100 has its factory default address set to address 01. If you already have an LH100 at this address or operate another XpressNet device on this address, you must set your new LH100 to another address.

Information on setting the XpressNet address can be found in the section Settings (Öp.61).

3.2Operating Your first Train

For this example we will assume that you are using a locomotive with the address 3.

3.2.1Selecting the locomotive address:

To operate a locomotive you must first enter the address of the locomotive into the LH100:

Press

On the display you see

Explanation

First clear the display, and begin entering the address

The number keyed in is displayed. If you keyed in the wrong number, you can clear the last entered digit with ‘CL’. You do not need to enter leading 0s of an address

You end the data entry with ‘Enter’. The direction of travel and the status of the functions for this particular locomotive will now be displayed. In this example the direction of travel is forward (arrow on left points up), the functions 0 (light symbol), F1, F3 and F8 are activated.

3.2.2Controlling the locomotive's speed:

The speed of travel of the locomotive is controlled with any one of the four following operation keys.

If you press any one of these keys and keep it pressed, the speed steps will automatically be increased (or decreased) until the maximum upper speed limit (or speed step 0) is reached.

Key

Explanation

Key

Explanation

Each time you press this key, you decrease (or slow down) the speed of the locomotive by 1 step until the locomotive is stopped

Each time you press this key, you decrease (or slow down) the speed of the locomotive by 5 steps in 14 throttle notch mode, 8 steps in 27 or 28 throttle notch modes, or 16 steps in 128 throttle notch mode. The locomotive will slow down at its programmed deceleration rate

Each time you press this key, you increase (or speed up) the speed of the locomotive by 1 step until the maximum speed is reached.

Each time you press this key, you increase (or speed up) the speed of the locomotive by 5 steps in 14 throttle notch mode, 8 steps in 27 or 28 throttle notch modes, or 16 steps in 128 throttle notch mode. The locomotive will speed up at its programmed acceleration rate

Pressing any of these keys will also cause the display to automatically change from showing the locomotive address to showing the locomotives current speed.

Each time you change the locomotive's speed, the display will automatically change from showing the locomotive's address to showing the locomotive's speed and direction. If speed step 0 (locomotive standing still) is reached, the display will automatically change back from showing speed steps to showing the locomotive address.

You can also toggle back and forth between displaying the locomotive's speed and the locomotive's address using the 'Enter' key.

Press

On the display you see

Explanation

If the locomotive address is shown, you can use the ‘Enter’ key to change to showing the speed steps.

This does not change the speed or direction of the locomotive.

3.2.3Changing the locomotive's direction of travel:

To change the locomotives direction of travel, first set the speed to “0”. Then you can change the direction of travel:

Key

Display

Explanation

Each pressing of this key changes the direction of travel of the locomotive. The changed direction will be shown in the display.

When the arrow is up the locomotive goes forward. When the locomotive points down the locomotive will

operate in reverse.

The direction of travel is tied to each locomotive, for example: with a steam engine, forward means “smokestack forward”, regardless of in what direction you have placed this locomotive on the track.

If the locomotive has speed step 00, each pressing of the '<>' key will change the direction of travel.

The '<>' key also has another function: It affects an emergency stop for the specific locomotive contained in the display.

If the locomotive is operating at a speed step greater than 00, pressing the '<>' key once will cause the locomotive being controlled to immediately stop without any pre-programmed deceleration. Only by pressing the '<>' key a second time will change the direction of travel, which is shown in the display by an arrow in the upper right hand of the display that points up (forward) or down (backwards).

3.2.4Emergency stop/Emergency off:

With the key you cause an emergency stop for the entire layout. When this key is pressed, all locomotives will immediately stop. By pressing this key again, the emergency stop is released. This operation of this key can be configured using the set

command. (Öp. 23)

At this point you have very quickly learned how to operate a locomotive with the LH100 throttle.

There are many more advanced capabilities that the LH100 provides. These features are described in the following sections. It is not important that you know how to use all these advanced features. You can learn to use them at any time in the future when you have a need.

4 Overview of the functions of LH100

This section will provide you:

-a short overview of each of the functions of LH100.

Specific details for using each feature follows in subsequent subsections, which follow this section.

4.1Controlling locomotives

4.1.1Selecting locomotive addresses

There are 3 different ways to select a locomotive address. Up to 9999 addresses for digital locomotives are available to you. With address 0 you control a conventional locomotive in the digital operation. More about entering and selecting locomotive addresses can be found in the section "Entering a new locomotive

address on the LH100 keypad" starting on page (Öp.16 ).

4.1.2Changing speed and direction of travel

You change the speed and the direction of travel of the locomotive with specially shaped keys described in the section "Changing

locomotive speed and direction" starting on page (Öp.16 ).

4.1.3Emergency stop

With the emergency stop you bring one or all locomotives to an immediate stop described in the section "Emergency stop and

emergency off" starting on page (Öp.23 ).

4.1.4Turning locomotive functions on and off

You can access up to 13 functions in each locomotive decoder.

You can also determine if the function operates as a on/off or momentary function. How you control locomotive functions is described in the section "Activating locomotive functions" starting

on page (Öp.19 ).

4.1.5Setting the Throttle-notches for a particular locomotive

With the LH100 you can select 14, 27, 28 or 128 Throttle-notches for the currently selected locomotive address. (Depending on the software version of `the command station you are using). This information is stored in the command station for subsequent use.

How you select the different Throttle-notches and match it to your locomotive decoder is shown in section "Showing and changing

throttle-notches" starting on page (Öp. 21 ).

LH100 Dispatcher’s Throttle

12

4.2The function menu of LH100

The LH100 function menu provides you access to all other functions of the LH100.

The different menu items can be reached in 2 different ways when you are in the locomotive control mode:

Option 1:

Press	and scroll through	until you reach the desired
	the menus with	menu

Option 2 (Quick access):

Press	and then the number of the desired function. The
	corresponding numbers can be found in the detailed
	description of each function.

Following is a brief description of each of the individual LH100 menu items.

4.2.1Setting locomotive decoder functions to on/off or momentary function

Each individual function between F1 and F12 can be configured on a per locomotive basis to either be on/off or momentary. In on/off operation the function is turned on with one keystroke and turned off with the next keystroke. In momentary operation the function is only turned on for as long as you keep the corresponding key pressed. When you release the key again, the corresponding function turns off again.

The procedure for setting this is described in "Configuring locomotive decoder functions" starting on page (Öp.25 ).

4.2.2Double header

Double heading allows you to easily assign two locomotives to a double header and then operate it as a single locomotive from either locomotive address. The procedure for setting this is

described in "Double herder" starting on page (Öp.27 ).

12

SET-01 Information

13

4.2.3Multi-Unit Consist (MU)

The LH100 implements smart consisting. Smart consisting allows you to set up a number of locomotives that can be operated as a single unit. As many as 256 locomotives can be controlled at the same time using a common consist address, which we call the locomotive's multi-unit consist address (MU-address). To you it is as if you only controlled one single locomotive, but all the locomotives in the MU react at the same time.

With the LH100 you can (depending on the software version of the command station you are using) control, assemble and disassemble multi-unit consists.

Detailed information is found in "Multi-unit consists (MU)" starting on page (Öp.32 ).

4.2.4Throwing turnouts and setting signals

Using your LH100 you can throw turnouts, set signals or activate relays. To allow control via the LH100, these devices must be connected to accessory decoders LS100/110/120 of Digital plus by Lenz ® system or other compatible modules. The procedure is controlling these devices using the LH100 is described in "Throwing turnouts and setting signals" starting on

page (Öp.38 ).

4.2.5Display feedback information

The LH100 can also be used to display the status of the inputs generated by feedback encoders LR100/101. These feedback encoders can be used for example to display occupancy of selected locations of your layout.

You find the directions for displaying feedback information in "Displaying feedback" starting on page (Öp.41 ).

LH100 Dispatcher’s Throttle

14

4.2.6Configuring decoder settings: Programming

Each decoder has settings that can be set to customize the decoder to an individual locomotive, for example the locomotive's address, acceleration and deceleration delays are configurable settings on a locomotive decoder. These settings can be changed by a technique we refer to as programming. The LH100 provides two programming methods. Which method you can use depends on your command station and its software version, as well as the locomotive decoders you use.

4.2.7Operations mode programming

Using operations mode programming or "Programming on the main', you can configure the settings of your locomotive decoder while the locomotive is being operated anywhere on the layout. For example, couple your locomotive in front of a heavy freight train and now adjust the acceleration delay to fit the train! Operations mode Programming is descried in "Programming on

the Maim (POM)" starting on page (Öp.46 ).

4.2.8Programming on the programming track

Using a separate programming track you can both configure and read back each of the individual locomotive decoder's settings. Information on programming using a programming track can be found in "Programming on the programming track" on page

(Öp.50 ).

4.2.9System settings

The LH100 allows you to configure several system settings. For example, you can program how the emergency stop button works, check and change the LH100 XpressNet address, read out the software version of your command station, and more. Detailed descriptions can be found in "Configuring the LH100 handheld

using the SYS menu" starting on page (Öp.61 ).

5The LH100 LCD Display

In this section you will learn about the LH100 two-row LCD display.

Depending on which mode of operation you are using, the display will look different. The display for the locomotive address always uses 4 digits. Zeros are added in front of the address if needed.

Here are examples of the most important displays:

A single locomotive with address 0003 is being controlled.

A locomotive with address 1234 is in a multi-unit consist.

A multi-unit consist with address 33 is being controlled.

Examples for the display of speed steps:

Speed step 1 in "28 speed steps" mode

1	2	6	8
			Speed step 28 in "28 speed steps" mode
			Speed step 1 in "128 speed steps" mode
1	2	6	8
			Speed step 126 is the maximum speed
1	2	6	in "128 speed steps" mode
			8

LH100 Dispatcher’s Throttle

16

While the speed step is displayed, the locomotive address is hidden. The direction of travel and the functions continue to be displayed.

6 Controlling locomotives with the LH100

In this section you will learn about basic locomotive control using the LH 100. When you want to control a locomotive, you have to call it up first. There are three different ways you can call up a locomotive you want to control:

-Enter the number of the locomotive on the LH100 keypad

-Toggle between 2 locomotive addresses

-Seek out a locomotive from the command station stack.

All addresses from 0 to 9999 are valid. Address 0 is intended for conventional locomotives (ones without a digital decoder).

When you first start using the LH100, it displays locomotive address 0003.

6.1Changing locomotive speed and direction

How to control a locomotive’s speed and direction of travel was already described in the section "First Steps: Controlling locomotives". Please refer back to this section on how to control the speed and direction of your locomotive.

6.2Entering a new locomotive address on the LH100 keypad

In the following example a locomotive address "1234" is entered using the LH100 keypad.

Press

On the display you see

Explanation

Clear the display first.

Begin to enter the address by pressing the first digit of the locomotive's address on the keypad.

If you make an error, you can use

to erase the last entered digit.

16

SET-01 Information

17

You continue by pressing each number in the locomotive's address

After you have entered the complete locomotive address you confirm the entry by pressing the 'Enter' key.

The information about functions,

direction and speed step

associated with this address will now be displayed.

If the display flashes after you call up a locomotive address, then the locomotive is already being operated by another hand held controller/ If you desire you can still take over control of this locomotive. More about this in "Taking over control of a locomotive

from another hand held controller" starting on page (Öp.19 ).

6.3Quickly toggling between 2 locomotive addresses

The ‘Esc’ key on the LH100 keypad can be used to toggle between the two locomotive addresses.

Changing the	Toggle between	Changing the
content:	memory 1 and 2	content:
Memory 1 old address		Memory 2 old address

Enter new address	Enter new address
Memory 1 new address	Memory 2 new address

For example: You have just called up locomotive 24. The address for that locomotive is now in one of the two LH100 locomotive memories.

Now press the ‘Esc’ key, and the display will change to the address that is in the second memory. This is for instance address 22. If you now want to operate a locomotive with the address 78, then press ‘Cl’, enter the address 78 and confirm with the ‘Enter’

LH100 Dispatcher’s Throttle

18

key. From now on, you can use the ‘Esc’ key to toggle between address 24 and 78. If you press the ‘Cl’ key, then the locomotive address in the memory currently shown is erased; the locomotive address in the second memory is still available for use.

6.4Selecting an address from the command station stack

The command station stack is a database that contains all the locomotive addresses that have been used together with the locomotive's associated data (speed step, function status). With this function you can select an address to control from any of the addresses the database:

Press

On the display you see

Explanation

First clear the display

The first locomotive from the command station stack is displayed. The “A” in the lower row shows that you are in the selection from the locomotive stack.

Each pressing of the ‘-’ key pages through the locomotive stack in the command station. The two first examples show single locomotive addresses.

This is an example of a locomotive address that is part of a multi-unit consist.

Here is a multi-unit consist address displayed for selection.

Keep paging until you see the locomotive address you want displayed.

Using 'Enter' you can now select the address of the locomotive you want to control. Direction and function status are now displayed.

18

SET-01 Information

19

You can also clear a locomotive from the command station stack, if this option is set in the system settings. For more information see section "SET_5: Erasing locomotive addresses from the

command station stack" starting on page (Öp.66 ).

6.5Taking over control of a locomotive from another hand held controller

When desired you will take over control of a locomotive that is being operated by another engineer. To do this you call up the locomotive's address. The locomotive’s information is now shown flashing. If you don’t want to take over control of the locomotive, but want to find out the current operational data for the locomotive, then each pressing the ‘Enter’ key will update the operational data of the locomotive in your display. If for instance the speed step of the locomotive is changed on the first hand held controller, you can observe that on your hand held controller’s display.

You take over control for this locomotive from the other handheld to your hand held controller by pressing one of the following keys:

The display no longer flashes, and on the display the newest operation and function data is shown. Now the display on the other hand held controller flashes. Only the next operation command (pressing one of the keys shown above) will be sent to the locomotive, which prevents unintended sudden changes of the speed.

6.6Activating locomotive functions

All Digital plus by Lenz ® locomotive decoders have one or more additional functions. The functions are numbered, beginning with 0. Altogether the Digital plus by Lenz ® system can reach up to 13 functions in locomotive decoders.

Functions 0-8 can be activated directly while you are controlling a locomotive (that is the locomotive address or the speed step is displayed), using keys the ‘0’ to ‘8’:

LH100 Dispatcher’s Throttle

20

Press

On the display you see

Explanation

This function 0 is assigned to the headlights in most locomotive decoders and is shown by the lamp symbol in the lower row of the display.

The state of functions 1 to 8 is shown in the second row next to the “F”.

If the functions are set to on/off mode (factory default), then the first key stroke turns on the function.

The next keystroke turns the function off again.

If the function is set to momentary activation, then it is only turned on for as long as the key is pressed. The display shows accordingly.

To turn functions 9 to 12 on and off, you must first switch the display over to the high order function block using the '9' key:

The "F" in the lower row changes to a slowly flashing "8".

The '1' key now turns on function 9, the '2' key function 10 and so on. You must simply add the number 8 to the displayed function (flashing display) .

To return to functions 1 to 8, again press the ‘9’ key.

By pressing one of the keys that turn functions on or off, you are also asking the DCC command station to send the locomotive an instruction to activate or turn off that specific function.

6.7Showing and changing throttle-notches

In this section you learn:

-what throttle-notches are

-which throttle-notches are available to you

-how to select different throttle-notches for individual locomotive addresses.

The area from stopped to maximum speed of a locomotive is divided into a series of throttle-notches. The more notches present, the smaller the division between different locomotive speeds. With the LH100 you can set the displayed locomotive address to have 14, 27, 28 or 128 throttle-notches.

This is how you show/change the speed step modes:

Press

On the display you see

Explanation

Call up the locomotive address whose number of throttle-notches you want to see or change. Make sure that the locomotive is on speed 0; if needed press the '<>' key.

After pressing the ‘+’ key the current number of LH100 throttlenotches is shown. 28 throttlenotches is the default for version 3.0

By repeated pressing of the ‘+’ key you are now shown the possible throttle-notches that are available.

To assign a desired number of throttle-notches to this locomotive address, press ‘Enter’.

)If the locomotive's speed is not 0, then the currently set number of throttle notches is shown as long as you keep the ‘+’ key pressed, but the mode cannot be changed.

LH100 Dispatcher’s Throttle

)For locomotive addresses 100-9999, only 28 and 128- throttle-notches are available for use.

)The locomotive decoder's speed step mode (set via CV29) must match the LH100 number of throttle–positions (Öp.42 ).

The following correspondence between system and locomotive decoder must be created:

System	Locomotive
	decoder
14 or 27 throttle-positions:	14 speed steps
28 or 128 throttle-	28 speed steps
positions:

Setting the locomotive decoder to a particular speed step mode is done in CV29 of the decoder. For details, see the Digital plus by Lenz ® "Information for locomotive decoders".

You must make sure that the locomotive decoder also “understands” the programmed speed step mode. For Digital plus decoders the following correspondence applies:

DIGITAL plus locomotive	supported speed step
decoder types	modes
NMRAXF or XS-series	14, 27, 28, 128
conforming decoders
Other NMRAconforming	14, 27, 28
decoders
all other DIGITAL plus decoders	14, 27

If unsure, please check in the decoder's operation manual. NMRAconforming Digital plus by Lenz ® decoders can be recognized by the following symbols on the title page of the operation manuals:
