What can LW120 do:
Use as a turnout throwing module:
A pair of keys or a single key in connection with a group key
directly throws a turnout, sets a signal, activates an uncoupler or
other device.
What can LW120 do in the future:
Use as train path module:
Pressing a single key calls up a switching chain on the tower cab.
This option is of special interest for setting multi-display signals.
Use as start-goal module:
Two keys are pressed after each other; the first key is the “start”
key, the second is the “goal” key. This key combination then calls
up the associated switching chain in the tower cab. In this setup,
any key can be both start and goal key. The logic always
evaluates the key pressed first as the “start” one and the following
key as the “goal” one.
Installation
LW120 has 4 holes for installation using the included screws. Use
the plastic tubes as spacers. Make sure that you do not damage or
bend any components when attaching the module. If you use
screws different from the ones included, please ensure that the
maximum diameter of 3mm (1/8”) is not exceeded. Similarly, the
screw heads must not touch traces or components on the circuit
board.

You want to throw turnouts 33 to 48 from the key module, you
program the DIP-switch as follows:
1234Turnout from-to
0100 33-48
Input 1 of the key module (in the picture to the
right next to the two “PLUS” terminals)
activates turnout address 33, input 2 address
34 and so on to input 16 that activates turnout
address 48.
Connecting keys
There are two different possibilities here, differing in operation and
the number of keys needed.
Version 1:
You use one pair of keys for each magnetic device. You press one
key for “diverge” (“stop”), the other for “straight” (“Go”).
Refer to the wiring example in the picture below for this version.
The example shows wiring of connections 1 and 4 of LW120. 2
keys each (in boxes) serve the setting of a magnetic device.
Example:
The key-module is programmed for turnout addresses 33 to 48.
Now when you press the left key T/S 1, this activates the “+”
terminal of output 1 of the LS100/110 programmed for turnout
addresses 33 to 36.

If on the other hand you press the right key, then this activates the
“-” terminal of output 1 of the LS100/110 programmed for turnout
addresses 33 to 36.
The terminals labeled “PLUS” and “MINUS” are designed as
double terminals, in case you need to connect several wires.
Please note that you must not connect the “PLUS” and “MINUS”
terminals of one key module with the same terminals of another
key module!
Version 2:
You first choose “Diverge” (“Stop”) or “Straight” (“Go”) with a group
key. Keeping this key pressed, you then also press a single key at
the turnout (signal). This version uses fewer keys total.
This wiring setup is shown in illustration 2. The two keys circled
are group keys, the boxed keys identify the turnout.

Example:
The key module is programmed for turnout addresses 33 to 48.
If you now press the “PLUS” group key and in addition key T/S1,
then the “+” terminal of output 1 of the LS100/110 that is
programmed for turnout addresses 33 to 36 is activated.
If you press the “MINUS” group key and in addition key T/S1, then
the “-” terminal of output 1 of the LS100/110 that is programmed
for turnout addresses 33 to 36 is activated.
The terminals labeled “PLUS” and “MINUS” are designed as
double terminals, in case you need to connect several wires.
Please note that you must not connect the “PLUS” and “MINUS”
terminals of one key module with the same terminals of another
key module! If you need several key modules in your graphic
display control panel, then you will need separate group keys for
each module!

Elements for display control panels
If you want to use ready made elements for building your graphic
display control panel, you must take note of this:
The keys for throwing turnouts and setting signals must be
electrically insulated from the displays (lightbulbs or LED's)!
Among the systems familiar to us this is the case with elements
from these manufacturers:
S.E.S. Schmidt in Berlin.
ROCO GBS Standard
HEKI: here only elements 9023D and 9024D.
