Lenz GmbH LS110 Version 2.2 NMRA DCC Switch Machine Decoder

LS100/110 Version 2.2 Accessory Decoder

ls110.gif (10044 bytes) The accessory decoders LS100/LS110 are the links between the DIGITAL plus system and accessory devices (e.g. turnouts, signals, uncoupling ramps, etc.) on your model railroad.

Please select from the following

General Information

The accessory decoder receives the commands send by the central command station through the power module and, for example, controls the switch machines on your turnouts (or the other devices). The commands are initiated from your input devices, such as the Basic Hand Held LH100, the Tower Cab LW100, the Computer Interface LI100 or the command station converter module LC100 (in connection with an Arnold or Märklin Digital system).
The accessory decoder LS100/LS110 are equipped with 4 outputs, with 3 terminals (+,C,-) each. These outputs can be connected to 4 twin-coil switch machines (or twin-coil actuators for your signals).

What's new in the upgraded LS100/110?

A push button and an LED have been added to the LS100/110 to make programming easier. Direct CV mode is now supported in service mode and a selectable flashing rate has been added.

LED:

Whenever the LS100/110 has received information destined for it, the LED will light up for a certain amount of time. This allows you to very easily verify that your LS100/110 is receiving information, and thus is correctly connected. If you, for instance, have called up the turnout address on the hand held controller and press the + or - keys, and keep them pressed, then the LED will flicker or stay lit. If you release the key, then the LED will also go out again. If this is not the case, then you may have selected the wrong address on the LH100, or the connection from the LV101 to the LS100/110 is not correct.

The LED is also used as a display during programming with the push button.

Push button:

The push button allows you to reprogram the address of an installed LS100/110. You can also reset it to the factory settings. The LED here serves to indicate the programming process.

Selectable flashing rate:

In the previous version, the flashing rate was permanently preset to 2 Hz. Now you have a range of 4 to 0.5 Hz. available.

Specifications of LS100/LS110

Up to 4 function devices each with a twin output can be connected to each LS100/LS110. Power for these function devices can by supplied by the track power or through an external power supply. Each function device output can have its characteristics individually set (by programming). In this way you can program each output with a variable pulse duration, a variable flashing operation or to a constant operation,. This allows the direct connection of lightbulbs or LEDs without additional relays.

The LS100 also has a connection for the feedback bus of the DIGITAL plus system. If the feedback bus is connected, then the position of turnouts can be sent back to the system when using suitable turnout drives. It is then possible to display a turnout being thrown by either DCC or by hand.

Electrical specifications:

Supply voltage:
8 - 18V	AC or pulsing DC
8 - 25V	pure DC (battery, lab power supply).
Current load capacity:
individual output:	1.7A continuous, 3 A peak (max. 20 sec.)
whole decoder:	1.7A continuos, as the sum of all outputs. 3A peak (max. 20 sec.)

More about settings the outputs

Pulse output:

Pulse output means that the output is on (active) for at least as long as a switching command is sent to LS100/LS110. The switching command is for example sent to LS100/LS110 as long as you keep the ‘+’ or ‘-’ key pressed on LH100.

The time that the function device output remains active after releasing the key—the pulse duration—is determined by a programmed numeric value. If during the activation time of this

pulse duration a new switching command is received by the LS100/110, the output remains active for another pulse duration.

Constant output:

By pressing the ‘+’ key on the LH100, the function device output + is activated and remains active until the ‘-’ key is pressed at which time the - output is activated. Thus either the + or - terminal of an output is active, the output operates as a toggle switch:

For example, if you were to connect a red lightbulb of a signal to an output’s + terminal, and the green lightbulb to the - terminal, then when you press the ‘+’ key, the red lightbulb will be on (the signal shows ‘stop’). If you press the ‘-’ key, then the green lightbulb is on (the signal shows ‘go’). This avoids the need to use an additional relay on light signals.

Flashing:

In this mode an output’s + and - terminals are activated alternatively.

This mode of operation is suited for connecting the flashing lights at a train crossing or signal. The flashing rate is programmable; see the section "Programming the settings of an output" for more information.

General notes: Only one of the output pairs on an LS100/110 is active at any one time. For example if during pulse or constant operation the + terminal is active and the - output is activated, then the + terminal goes inactive, regardless of whether the pulse duration time is up or not. This applies in the corresponding manner when the - terminal is activated first and the + terminal is then activated.

Caution!

When programming the outputs, please note that depending on pulse duration, or with constant operation, several outputs may be active at the same time. With all the connected power users, you must then not exceed the maximum total current load capacity of 3A for the accessory decoder.

Programming the Address and the Output Modes

In the following examples the settings of output 1 of LS100/LS110 are programmed. Outputs 2, 3 and 4 are programmed in the same manner, only with the corresponding change of the storage location.

First connect the accessory decoder to the programming output of the command station, as described above, and change into programming mode with the hand held controller.

Select register 3. In this position the settings of output 1 are stored (see Table 1).

Example 1: Setting pulse operation with shortest pulse duration.

As you see from tables 2 and 3 above, you must enter the number 1 on hand held controller LH100 as the value to be programmed. Then start the programming with the ‘Enter" key.

Example 2: Setting to constant on:

Enter 32 as the value to be programmed on hand held controller LH100 (see Table 2). Start the programming sequence with the ‘Enter’ key.

By entering other values from table 3, you can choose to define the other settings.

The Connectors of the Accessory Decoder LS110

The terminals marked with the symbol supply the decoder internal negative potential. These terminals are needed for programming and to connect to external track contacts.

Figure 1:The terminals of the LS110.

The Power Station LV100 is connected to the terminals J and K. The cable connected to these points supplies the commands to the decoder. The cable should be a twisted pair.

The terminals with the AC symbol('~') are for connecting a 16 Volts AC power supply. This supply powers the accessory decoder and the accessories themselves. Since the accessories are powered from the external supply, they do not use the 'expensive' digital power. If necessary, it is possible to use the digital power instead.

The three pole terminals labeled 'Ausgang 1' to 'Ausgang 4' (German for 'Output 1' to 'Output 4') are connected to the accessories.

Connecting the LS100/LS110 to a power station and/or separate power supply line

Before you connect your LS100/LS110 to your NMRA DCC system or the power supply line, you must turn off your DCC system and disconnect the power supply (unplug the transformer from wall outlet). There are two options for connecting your LS100/LS110: The first option uses the power supplied by your

DCC system and does not use a separate power supply line to power the LS100/110. The second option uses an external power supply to power the LS100/110. Illustrations 1 and 2 show the connection using the LS110. The LS100 is connected in the same way, using the same terminals.

Connecting with an separate power supply:

As shown in figure 2 (left), connect the terminals J and K on the LS110 decoder to the corresponding terminals on the Power Station LV100. Connect the '~' terminals to a 16V AC power supply.

Figure 2: Connecting the LS110 to the LV100 and a separate power supply Figure 3: Connecting the LS110 to the LV100

Connecting without a separate power supply:

Figure 3 (right) shows this variant for connecting the LS110. The '~' terminals are wired in parallel to the terminals J and K on the LV100. The current for switching the accessories is taken from the digital supply, thus reducing the total power available

Connecting the Accessories

Connecting twin-coil switch machines:

The common terminal (2) of both coils is wired to the terminal 'C'. The wire from coil number 1 (1) is connected to the '+' terminal; the wire from the coil 2 (3) is connected to the '-' terminal. Depending on the wiring of the switch machine, this will result in a specific route upon activation of the '+' contact, for example 'diverging'. In order to adjust the route to your preference, you may exchange the wires leading to the '+' and '-' terminals.

The following table gives the color codes for some (European) manufactures of twin-coil switch machines with respect to the numbering in figure 4.

Cable No.:	1	2	3
ROCO	red	black	green
Arnold	blue	gray	violet
Fleischmann	beige	black	brown
Trix	yellow	black	green
Märklin	blue	yellow	blue

Connecting Signals with Bulbs or LED's:

If you are using light signals with bulbs or LED's, you can program the outputs of the LS110 for continuous mode. The bulbs or the LED's (with a current limiting resistor) can be connected directly to the output of the LS110. Using an external AC power supply ensures that the digital power station is not overloaded.
Information on the programming of the different modes of the LS110 is given in the chapter "Programming the LS110" on page 11.
Connecting a signal with bulbs or LED's to the LS110 is shown in figure 4, upper and lower left hand corner, respectively.

Important:

When connecting LED's, please be advised that the terminal 'C' is on positive potential. Therefore, the cathode of the LED's has to be connected to the '+' and '-' contacts.
In order to operate LED's of the outputs of the LS110, a current limiting resistor has to be used. Please check for this resistor in your brand of signals.
In case there is no current limiting resistor included with your signal, a resistor of 1.5 kOhm should be used with a 16V AC power supply. If the diodes are not bright enough, decrease the value of the resistor (1 kOhm), if the diodes are too bright, increase the value of the resistor. In figure 4, the resistor is labeled 'R'.

Connecting a slow-motion turnout motor:

The adapter LA010 is necessary to connect a slow-motion turnout motor to the LS110, as shown in figure 4, lower right hand side. This adapter changes the polarity at the motor terminals for the correct sense of rotation.
The use of this adapter precludes complicated circuitry with relays to power the slow-motion turnout motors.
For use with a slow-motion turnout motor, the output should be programmed to momentary action and the pulse duration should be set so that the motor is rotating until it reaches the end position.
Information about the programming is given in the following section.
