Introduction/Safety instruction:
You have purchased the Light-Signal Decoder LS-DEC-SNCF for your
model railway as a kit or as finished module.
The LS-DEC is a high quality product that is supplied within the Digital-
Professional-Series of Littfinski DatenTechnik (LDT).
We wish you having a good time using this product.
The Light-Signal Decoder LS-DEC of the Digital-Professional-Series
can be easily operated on your digital model railway.
By using a connector plug bridge you can choose if you want to
connect the decoderto a Märklin-Motorola system or to a digital system
with DCC standard.
The finished module comes with 24 month warranty.
•Please read the following instructions carefully. Warranty will expire
due to damages caused by disregarding the operating instructions.
LDT will also not be liable for any consequential damages caused by
improper use or installation.
Connecting the decoder to your digital model railway
layout:
•Attention: Before starting the installation-work switch off the
layout voltage supply (switch-off the transformers or disconnect
the main supply).
The Light-Signal Decoder LS-DEC is suitable for the DCC data format
whenever no connector plug bridge is inserted in position J2.
The decoder is suitable for Märklin-Motorola data format, if you insert a
connector plug bridge on J2.
The decoder receives the digital information via the clamp KL2.
Connect the clamp with a rail or even better connect the
clamp to an own
digital main ring supply assuring the supply of digital information to be
free from any interference.
Please attend to the marking on clamp KL2. The colors 'red' and 'brown'
next to the clamp are usually used by Märklin-Motorola systems (e.g.
Märklin-Digital~ / Märklin Systems / Intellibox DiCoStation / ECoS /
EasyControl).
Lenz-Digital systems are using the letters 'J' and 'K'.
The decoder receives the power supply via the two poles clamp KL1.
The voltage shall be within a range of 14...18V~ (alternate voltage output
of a model rail road transformer).
If you do not want to supply voltage separately from a transformer to
the LS-DEC decoder you can connect the clamp KL1 to clamp KL2
with two wires. In this case the decoder will get the power supply
completely from the digital network.
Connecting the signals:
General:
Up to 4 signals can be connected to the Light-Signal Decoder LS-DEC.
Two signals per each 11poles clamp bar. The connection sequence of
the two clamps is identical. Thefollowing description refersmainly to one
clamp only. As you can see at the identical markings the description is
also valid for the second clamp.
Common connection:
All LED-signals of any manufacturer are designed in accordance to the
same principle. One wire of all light emitting diodes of a signal will be
generally connected to a common cable. Depending if all anodes or all
cathodes are connected together the signals will be called as common
anodes- respectively common cathodes-signal.
If you use signals with common anodes, you have to clamp this cable
to the connection marked '+'. In addition you shall not insert the
connection plug bridge in J1 in this case.If you use signals with
common cathodes you have to clamp this cable to the connection
marked '-'. In this case you shall insert the connection plug bridge in
J1.
The second connection of each light emitting diode is separated and
mostly color marked at the end and contains a series resistor.
Series resistors:
Light emitting diodes have always to be operated with a suitable
series resistor to prevent that they will be destroyed. For this prevention
all outputs contain already a series resistor of 330 Ohm integrated on
the printed circuit board of the Light-Signal Decoder LS-DEC. Is there
no further external resistor available the diode-current will be about 10
mA. This provides sufficient brightness.
For assigning the single cables of the light emitting diodes to the
correct clamp connection please attend to the below signal images.
The marks next to signal light diodes are not corresponding to the
actual light-color but to the marking of the connection at the Light-
Signal Decoder LS-DEC.
If you do not know the correct allocation of the single wires to the light
emitting diodes you can test the function by connecting the wires to
clamp RT1. This output is active because the decoder switches all
signals to red after switching on.

Further sample connections are available at the internet on our Web-
Site (www.ldt-infocenter.com) at the section “Sample Connections”.
Additionally you can find detailed information about the Light-Signal
Decoder LS-DEC-SNCF at our Web site within the section “Digital-
Compendium” at chapter 2.
Programming the decoder address:
•The jumper J3 has to be inserted for the programming of the
decoder addresses.
•Switch-on the power supply of your model rail way.
•Activate the programming key S1.
•At least two light emitting diodes on a signal connected to the left
clamp block (on this decoder side is the programming key S1) will
be automatically switched over every 1.5 seconds in a flashing
mode. This indicates that the decoder is in the programming mode.
•Press now one key of the fourfold address-group to be assigned
to the left clamp block of the decoder. For programming the decoder
address you can as well release a turnout switch signal via your
model railway software.
•Remarks: The decoder addresses for magnet accessories also to
be used for switching the signal-aspects are combined into groups
of four. The address 1 to 4 will be the first group. The address 5 to 8
will be the second group etc. Each clamp block of a LS-DEC decoder
can be assigned to any of these groups. It does not matter which of
the eight possible keys used for programming will be activated. The
decoder stores always the complete group of keys.
If the Light-Signal Decoder LS-DEC shall control on this clamp bar
two 2 to 4 aspect signals or one up to 16 aspect signal this has
to be adjusted together with the decoder address. If you activate
within the programming mode one key of the desired group of four
keys designated for switching a turnout straight or a signal to green
the decoder will be set for the controlling of two 2- to 4-aspect
signals.
If you activate a key for switching a turnout round or a signal to red
you have selected the option to switch one up to 16-aspect signal.
For both programming modes (left and right clamp bar) you can
individual select if two 2- to 4-aspect signals or one up to 16-
aspect signal shall be digital controlled.
•If the decoder has recognized the assignment correctly the
connected light emitting diode will flash a little faster. Afterwards
the flashing slows down to the initial 1.5 seconds again.
In case the decoder will not recognize the address it could be that the
two digital information connections (clamp 2) are wrong connected.
For testing this, switch off thepower supply, exchange the connection
on KL2 and start addressing again.
•Press now the programming key S1 again. At least two light
emitting diodes connected to the right clamp block will flash now.
Repeat the programming of this fourfold-address block as
described above.
•Now press the programming key S1 a third time for leaving the
programming mode. All signals will be automatically switched to
STOP.
Signal switching:
The opposite sample connections show how the fourfold address-
group can be set by use of 8 keys of the push button panel for setting
the turnouts or signals. Between each pair of keys are e.g. the addresses
1 to 4. The two keys red and green for each address are assigned to
the turnout position round or straight respectively the corresponding
signal aspect which is indicated above or below the key. The actual
address section is related to which fourfold address-group has been
selected during the programming.
If you use a remote control LH100 of Company Lenz Elektronik then
red will be the minus key and green the plus key.
1. Two 2- to 4-aspect signals on each clamp bar:
If you have adjusted the Light-Signal Decoder LS-DEC-SNCF for
switching two 2- to 4-aspect signals by programming one clamp bar
as shown at the picture under 1. on the first page of this instruction you
can e.g. switch the first signal to drive (Voie libre VL) with address 1
and key green.
Please activate the key green of the address 3 and the second signal
will be switched to drive (Voie libre VL).
The first signal will be always switched via the address 1 and 2. The
second signal of the clamp bar will be switched via the address 3 and
4of the programmed four fold address group.
2. One up to 16-aspect signal on each clamp bar:
If you have adjusted the LS-DEC-SNCF by programming the address
of one clamp bar for switching one up to 16-aspect signal the picture
left under 2 will indicate the status.
Via the two first addresses of the clamp bar of this programmed four
fold address group is it possible to switch four signal aspects.
As a total of 16 signal aspects can be controlled the selection of one of
four signal aspect groups has to be performed via the addresses 3
and 4. The occupancy of keys below the signal shows the relation. After
switching–on the signal indicates stop (Carré C). If now e.g. the aspect
Ralentissement 30 R shall be indicated is it required at first to activate
the address 4, key red for the third signal aspect group and then the
address 1key red.
Only the thick framed keys of the table will be required for switching the
signal.
Accessory:
For the assembly of the LS-DEC below your layout base plate we offer
an assembly set under the order code MON-SET. For the assembled kits
and the finished modules we offer a suitable case under the order code
LDT-01.
Attention:
The Light-Signal Decoder LS-DEC switches the signal aspects not just
on and off but is dimming the light emitting diodes realistic up and down.
Even between the signal aspects a short off-phase is provided. Further
digital commands received during this switch-over-time of about 0.4
seconds will not be taken up from the decoder. Please take care that the
switching-commands are not in a too fast sequence. The impression is
absolutely realistic if the switching is considerable slow.
If the jumper J3 will be removed after programming of the decoder
addresses the memory storage of the Light-Signal Decoder LS-DEC
will be protected against any alteration. Made in Europe by
