1.2 Track occupancy detection at a two-conductor system with two isolated rails!
Isolated track sections get the supply complete via one output of the track occupancy detector.
This is very convenient for modular layouts with detachable single components.
This makes it possible to control a total of 8 track sections.

1.3 Connect the track occupancy detector to the RS-feedback bus.
The inputs R and S of the 4-poles clamp have to be connected to the equal marked clamps at the
central unit LZ100.
Several feedback modules (RS-8, LR101, LS110 etc.) can be simply connected in parallel.

Track occupancy report and disconnectable track section with track occupancy detector RS-8 and SA-DEC-4
The isolated sections 1 and 2 are getting the supply of digital voltage via the feedback module with
integrated track occupancy report RS-8. As soon as there is a current consumer within a monitored
section this will be reported via the RS feedback bus to the central unit LZ100.
The section 2 can be additionally switched current-free via an output of the switch decoder SADEC-4. If there will be illuminated trains parked they will not consume expensive digital current.
The resistor of 1,5 k-Ohm has to be assembled in any case to assure that the track occupancy
monitor is able to supply an occupancy report even at a current-free status in case a current
consumer will be within the monitored section. The value of the resistor assures that the trainillumination will not be switched on during switched off status.

The RS-8 is divided into two 4-fold track occupancy monitors. The booster 1 controls and supplies current via the
RS-8 to the left track and the booster 2 to the right track.
The 8-fold track occupancy detector RS-8 is divided into two 4-fold track occupancy monitors
from version 2.0.
This makes it possible to control tracks from two different booster circuits. At the above draft the
input IN1 of the RS-8 gets the supply from booster 1 and the input IN2 from booster 2.
The monitored tracks 1 to 4 (at the draft track 1 has been indicated) receives the digital current
therefore from booster 1 and the tracks 5 to 8 (at the draft track 5 has been indicated) from booster
2.
The partitioning of the RS-8 into two 4-fold track occupancy monitors has got an additional
advantage for the control of reverse loops. For further information regarding this issue please load
the file "kehrschleife_21_engl.zip" from our web-site (www.ldt-infocenter.com) onto your
computer.
