What is the function of LW130:
The basic purpose of LW130 is to display feedback information.
For Example, this can be the position of turnouts, or the display of
occupied track blocks.

2LT100 Digital Circuit Breaker
Prerequisites for displaying feedback information
With LW130 you can display feedback information that comes
from feedback capable accessory decoders LS100 or feedback
encoder LR100.
If you want to make the position of a turnout (or signal) visible on
your control panel, then the drive of that turnout (or signal) must
be connected to a LS100. The respective feedback inputs and
also the feedback bus (R,S) must be connected as well.
The positions of a device connected to the non-feedback capable
LS110 can not be displayed.
Occupancy status can be made visible when you use track
occupancy detector LB100 in connection with feedback encoder
LR100.
Installation
LW130 has 5 holes for mounting using the enclosed screws. Use
the plastic tubes as spacers. Be careful not to damage or bend
any components on the module when tightening it down. If you
use screws other than those included, please make sure not to
exceed the maximum diameter of 3 mm (1/8”). The screw heads
must also not touch traces or components on the circuit board.
Connecting to LW100
The terminal row labeled “GZIO” is to be connected with the
corresponding terminals on LW100. The “GZIO” terminals are
present twice on LW130. It does not matter which one you use for
connecting to LW100. The other terminal set can then have
additional LW130 or LW120 modules connected to it. The order of
connection is hereby arbitrary.
Connecting the supply power
LW130 needs a separate power supply of 10-16V AC or DC such
as the TR16. This power supply is connected to terminals UV.
Operation with too high voltage will damage LW130! Damage
from operation with too high voltage is not covered by the
warranty!
You can connect LW100, LW120 and LW130 together to the
same transformer, as long as the capacity of that transformer is
large enough. The supplying transformer must be able to deliver
the sum total of all the connected devices.

Maximum current of the outputs
A maximum current of 50mA may flow at each output of LW130.
Ensure that the sum of the current draw of all lights connected to
one output is not greater than 50mA.
In an overload from too high current draw, LW130 will be
damaged! Damages from overloads are not covered by the
warranty!
Light bulbs generally have a current draw of 50mA, so that only
one light bulb may be connected per output.
Therefore if you want to use several lights per output (for instance
to display track occupancy), then preferably use LEDs with as
small of a current draw as possible.
Calculating the current draw of LW130
The current draw of LW130 is determined by the number and
type of connected lights. You can use light bulbs or LEDs, and, if
you like, in any combination. Simply add up the current draw of all
the individual lights. You then get the total current need for the
displays. To that is added the no-load current draw of LW130.
That is TBD mA.
The total current draw determined in this manner must be
available from the transformer that supplies your LW130.
Example:
Your LW130 has 6 light bulbs each drawing 50mA and 22 LEDs
drawing 5mA each connected to it. All together that makes for a
current draw of 410mA. Thus the transformer used to supply
power must be able to provide (at least) this current. If you also
want to supply additional LW130s with the same transformer,
then simply add together the current draws for each LW130 to get
the total current the transformer must deliver.

Organization of the feedback information
The DIGITAL plus system at the moment manages 1024
feedback information positions (FP).
For turnout feedback from one turnout, 2 feedback positions are
needed; for a track occupancy, one feedback position:
Turnout with address
uses feedback positions
11 and 2
23 and 4
35 and 6
47 and 8
An accessory decoder LS100/110 that is programmed for
addresses 1 to 4, thus occupies feedback positions 1 to 8. This is
independent of whether it is a feedback capable accessory
decoder or not!!
The feedback encoder with address 1 also occupies feedback
positions 1 to 8. Therefore never use feedback encoder address 1
at the same time as turnout addresses 1 to 4! For more on this,
please also refer to the table in the manual for LR100.
Only the lower half of the feedback positions are shared by
accessory decoders and feedback encoders. Feedback positions
from 513 and up are used exclusively by feedback encoders
LR100.
Setting the group address
A LW130 can display information for 32 sequential feedback
positions. For the LW130 to know which group it is to show, it
needs its own group address. This group address must be set on
the DIP-switch. To set this, switches 1 to 5 are used.
Set the address using table 1. A “1” in the column “Switch
number”, means that the switch is “ON”, a “0” means that the
switch is “OFF”.
Column FP shows you the range of displayed feedback positions,
column “FA” corresponding feedback encoder addresses, column
“TA” corresponding turnout addresses. Switches 6 to 8 on the
DIP-switch are reserved for future use, and must all be set in
position “OFF”!

Table 1: Setting the group address and division of address ranges
Example 1:
You want to show the position of turnouts 33 to 48 with the
display module. To do that, set the DIP-switch as follows:
12345FP FA TA
0100065-96 9-12 33-48
Outputs 1 and 2 now display the position of turnout 33. Output 1
becomes active when the “+” terminal of the corresponding output
on the accessory decoder was activated. Output 2 becomes
active when the “-” terminal of the corresponding output on the
accessory decoder was activated.

6LT100 Digital Circuit Breaker
Outputs 3 and 4 now show the position of turnout 34, and so on
to turnout 48, whose position is displayed by outputs 31 and 32.
Example 2:
You want to display track occupancy status with your LW130. The
occupancy detectors have been connected to a feedback encoder
LR100 for this purpose and it has address 65.
The correct setting of the DIP-switch according to table 1 is:
1 2345FP FA
0 0001513-544 65-68
You get the following displays:
LW130 output used to
show the status Input on LR100 at address
11 / 65
22 / 65
33 / 65
44 / 65
55 / 65
66 / 65
77 / 65
88 / 65
You can use the same LW130 both for displaying turnout
positions and for displaying information from feedback encoders,
as long as you split up the addresses of accessory decoders and
feedback encoders correctly.
For this the following example:
Setting on LW130:
1 2 3 4 5 FP FA TA
0 1 0 0 0 65-96 9-12 33-48
From column FA you see that feedback positions 65 to 96 can be
displayed by this LW130. As an example, the following division is
possible:
On outputs 1 to 16 the positions of turnouts that are connected to
2 LS100 with turnout addresses 33 to 36 (first LS100) and 37 to
40 (second LS100) are displayed and on outputs 17 to 32 you
see

LT100 Digital Circuit Breaker 7
DIGITAL plus
the status of occupancy detectors that are connected to a
feedback encoder with addresses 11 and 12: Output 17 shows
the status at input 1 of address 11, output 32 the status at input 8
of address 12 of the LR100.
Connecting displays
After the complicated previous chapter now follows the wiring of
displays.
Here there are two different options, depending on whether light
bulbs or LED's are used. You may connect both light bulbs and
LED's to the same LW130.
Version 1, light bulbs:
This is the simplest form of connecting displays. Just connect one
lead of the light bulb with the desired output, and the other lead
with the “++++” terminals. These 4 terminals are all wired in
parallel.
Please note that the maximum current draw allowed is 50mA.
The voltage of the light bulbs used must be the same as the
voltage used to supply the LW130.
Version 2, LED:
Here you need a current limiting resistor for each LED in addition
to the LED, and you must know where the cathode and where the
anode of the LED are to be connected.
The common connection for all lights is the “++++” terminal. It is
“positive polarity”. Outputs 1 to 32 are “negative polarity”.

8LT100 Digital Circuit Breaker
From this follows that a LED must be connected with its cathode
to the output (1 to 32) and with its anode to the “++++” terminal. It
makes no difference if you install the necessary current limiting
resistor on the cathode or anode side; just remember that each
LED needs its own resistor.
The following table is a guide for determining the value of the
resistor. The values listed apply when using a voltage supply of
16V. LED current Resistor
3 mA 5.6 kOhm
5 mA 3.3 kOhm
10 mA 1.5 kOhm
Components for display control panels
If you use ready-made components to build your display control
oanel, you must make note of this:
The lights in the components (lightbulbs or LEDs) must not
exceed the allowed maximum current of 50mA per output!
If the components have LEDs installed in them, you need to
ensure that the required resistors are present as well. If they are
not, you must connect them in addition.
Ready-made components often have 2 LEDs connected together.
In this case these LEDs must be joined at their anodes, and each
LED needs to have its own resistor, or it must be possible to add
one afterwards!
