Introduction/Safety instruction:
You have purchased the 4-fold switch decoder SA-DEC-4for
your model railway supplied within the assortment of
Littfinski DatenTechnik (LDT).
We are wishing you having a good time using this product.
The SA-DEC-4-DC is suitable for the DCC Data format, used
for instance at the systems of Lenz-Digital Plus, Arnold-,
Märklin-Digital=, Intellibox, TWIN-CENTER, Roco-Digital,
EasyControl, ECoS, KeyCom-DC, Digitrax, DiCoStation and
Zimo.
The decoder SA-DEC-4-DC can not only switch turnouts via the
turnout addresses but also responds to loc-addresses.
Therefore is it possible to switch consumers with the keys F1 to
F4 of the Lokmaus 2® or 3®.
The decoder SA-DEC-4-DC is multi digital and can be
installed to the Intellibox and on the TWIN-CENTER without
any problems.
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 be not liable for any consequential.
Connecting the decoder to your digital
model railway layout:
•Attention: Before starting the installation switch off the
drive voltage by pushing the stop button or disconnect
the main supply.
The decoder receives the digital information via the clamp
KL2. Connect the clamp directly to the command station or to a
booster assuring supply of digital information free from any
interference.
The DCC-Digital-Systems uses different color codes
respectively indications for the two digital cables. Those
markings are indicated next to the clamp KL2.These markings
have not necessarily to be maintained correct as the decoder
converts the signal automatically to be correct.
The decoder receives the power supply via clamp KL1.
Voltage in the range of 14 to 18V~ is acceptable (alternate
current output of a model railway transformer).
If you do not want to supply power to the decoder SA-DEC-4
separately from an external transformer you can connect the
clamp KL1 to KL2 with two wires. In this case the decoder will
get the power supply complete from the digital system.
Now connect the consumers (e.g. illumination, motors or
turnout-and signal coils with end-switch) to the outputs 1 to 4.
The clamp marked 'COM' is the common connection for the
respective switch-over contact.
Programming the decoder address:
For programming the decoder address you can connect a
consumer to the output 1. As it is possible to hear the switching
of the bistable relay the connection of a consumer is not
mandatory.
•Switch on the power supply of your model rail way.
•Adjust the speed of all connected speed controller to zero.
•Press the programming key S1.
•The relay connected to output 1 will now automatically
switch-over every 1,5 seconds. This indicates that the
decoder is in the programming mode.
•Switch now one turnout of a group of four assigned to the
decoder via the keyboard of the control unit or via a remote
control unit. For programming the decoder address you can
also release a turnout switch signal via a PC-software.
Remarks: The decoder addresses for magnet accessories
are combined in groups of four. The address 1 to 4 build
the first group. The address 5 to 8 build the second group
etc. Each SA-DEC-4-DC decoder can be assigned to any of
these groups. Which of the 4 turnouts of a group will be
activated for the addressing does not matter.

•If the decoder has recognized the assignment correctly the
relay will move a little faster. Afterwards the movement
slows down to the initial 1,5 seconds interval again.
•Leave the programming mode by depressing the
programming key S1 again. The decoder address is now
permanently stored but can be changed at any time by
repeating the programming as described above.

•If you press the first key of the programmed group of keys or
you send a switch signal for this address from a PC the
addressed bistable relay should now switch the connected
consumer on or off.
Switching consumers via loc-
addresses (e.g. Lokmaus 2® or R3®):
The decoder SA-DEC-4-DC makes it possible to switch
consumer via loc-addresses. For example switching with the
functional keys F1 to F4 of the Lokmaus 2® or R3®.
The function key F1 will switch the consumer at the output 1
and the key F2 will switch the consumer at the output 2 etc.
Each stroke on a function key will switch-over the
respective relay. Therefore can the connected consumers to
be switched on and off.
For programming the decoder address you can connect a
consumer to the output 1. As it is possible to hear the switching
of the bistable relay the connection of a consumer is not
mandatory.
•Switch the power supply of your model rail way on.
•Adjust the speed of all connected speed controller to zero.
•Press the programming key S1.
•The relay at the output 1 shall move now automatically
every 1,5 seconds. This indicates that the decoder is in the
programming mode.
•Adjust now on one of the Lokmauses the required address
and turn the speed adjusting dial off from the center
position. If the decoder has recognized the assignment
correctly the connected turnout drive will move now a little
faster. The decoder SA-DEC-4-DC will accept loc-
addresses between 1 and 99.
•Adjust the speed now to zero again. The relay of the output
1 will move now a little slower.
•Press the programming key S1 again for leaving the
programming mode.
•With each stroke of the functional key F1 you can switch
the connected consumer at the output 1 on or off. If there
are consumers connected to the output 2 to 4 of the
decoder SA-DEC-4-DC you can shift the respective
registered turnouts with the programmed loc-addresses with
each stroke of the function keys F2 to F4.
Please attend to the following:
•All 4outputs can switch consumers with up to 4 Ampere
each.
Decoder application:
Besides the switching of illumination and motors there is an
excellent application for the decoder SA-DEC-4of digital
switching of jammed turnouts with end switches.

As an advantage large current consuming drives will not
unnecessary overload the expensive digital power supply.
Feed the SA-DEC-4via the clamp KL1 witch AC from the
model railway transformer. Further connect one cable of the
transformer with clamp 'L' on the turnout drive.
Connect the second cable of the transformer with the clamp
marked with 'COM' on the respective decoder output.
Now, connect the two remaining clamps of the decoder output
with the outputs 1and 2of the turnout drive.
Further application examples can be found in the Internet on
our Web-Site (www.ldt-infocenter.com) at the section
downloads/sample connections.
Trouble shooting:
What to do if something is not working as described above?
Here some possible functional errors and possible solutions:
1. During programming of the decoder addresses the relay
on output moves within 1,5 seconds, but does not confirm the
programming with faster movement by pressing any key.
•Interfered digital information at KL2 respectively lost of
voltage at the tracks! Connect the decoder directly with
cables to the digital control unit or to the booster instead to
the tracks.
•Eventually the clamps have been tightened to strong and
therefore the clamps got loose at the soldering to the pc
board. Check the soldering connection of the clamps at
the lower side of the pc-board and re-solder them if
required.
2. The turnout connected to output 1 will move always at a
faster sequence after activating the programming key S1.
•Start programming the switch decoder SA-DEC-4-DC
immediately after switching-on the command station
before any loc is traveling on the track.
•Perform a RESET of the command station. All stored data
will be preserved but the address-repeating-memory will
be deleted. For Intellibox and TWIN-CENTER please
switch-on the unit and press the keys GO and STOP
simultaneous until the report “reset” can be red at the
display.
