Multi-Digital
Reverse-Loop Module
from the Digital-Professional-Series !
KSM-SG-F LDT-Part-No.: 700502
>> finished module <<
Suitable for the digital operation of all digital
formats
The polar reversal at the reverse-loop will be
performed without short-circuit via two sensor rails.
With reason to an external power supply possibility
is a simple control of the reverse-loop with track
occupancy module (e.g. RM-GB-8(-N) and RS-8)
possible. The sensor rails will be controlled as well.
This product is not a toy! Not suitable for children under 14 years of age! The kit
contains small parts, which should be kept away from children under 3! Improper
use will imply danger or injuring due to sharp edges and tips! Please store this
instruction carefully.

Introduction/Safety instruction:
You have purchased the reverse-loop module KSM-SG for
your model railway layout.
The KSM-SG module is a high quality product that is supplied
within the Digital-Professional-Series of Littfinski
DatenTechnik (LDT).
We are wishing you having a good time using this product.
• 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
damages caused by improper use or installation.
The KSM-SG comes as finished module and as finished
module in a case with 24 month warranty.
Connecting the reverse-loop module 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 reverse-loop module receives the power supply via the
clamp KL5. The voltage of 16...18V~ of a model railway
transformer (ac output) is acceptable.
Operation mode:
The reversal polarity of the reverse-loop will be performed
without short circuit due to 2 sensor-tracks which are
located at the entrance and at the exit of the reverse-loop.
Both rails of the sensor tracks (A1/B1 and A2/B2) and the
reverse loop (AK/BK) will be completely isolated and
connected to the respective marked clamps at the reverse-
loop module KSM-SG.
The sample connection 1 at the rear side of this instruction
shows the complete wiring.
The optimal length of the sensor rails will be 5 to 20 cm. The
reverse-loop rail gets the supply via the clamps AK and BK.
The reverse-loop rail has to have at minimum the length of
the longest train of the layout.
The reverse-loop KSM-SG can switch up to 8 Ampere digital
current.
The input A and B of the reverse-loop module KSM-SG will
receive the digital current from the command station or from a
booster from the ring-conductor “driving”. It is important that the
reverse-loop will be complete inside one booster area and
not between two rail sections which get the supply from two
different boosters.
Because the KSM-SG itself requires no digital current and
receives the energy from a model railway transformer is a
simple wiring for the control of the reverse-loop in
combination with track occupancy sensors possible.
The sample connections 2 at the rear side of this instruction
shows the reverse-loop control via the feedback module RM-
GB-8(-N) with integrated track occupancy report.
The reverse-loop module KSM-SG inputs A and B receive
digital current from one of the 8 outputs of the RM-GB-8(-N).
On this process will be every current consumer within the
reverse-loop recognized and produces an occupancy report.
The sensor tracks will be controlled as well.
Further information related to the control of reverse-loops
can be found at the Internet on our Web-Site (www.ldt-
infocenter.com) within the section “Downloads”. Please
download the file “Reversing loop monitoring” onto your PC.
At the section “Sample Connections” on our Web-Site are
additionally samples for the reversal polarity with the reverse-
loop module KSM-SG for further track layouts available.
Accessories:
For safe installation of the reverse-loop modules below your
model layout we offer an installation set under the order code
MON-SET and for the assembled kits a sturdy exact matching
case (order code: LDT-01).
