Feedback Bus: Terminals R,S - Lenz Digital Plus LZV200 Betriebsanleitung

38 Information LZV200
When the terminal E of the command station is connected to the
terminal E of the amplifier, the amplifier will communicate an overload
or a short-circuit to the LZV200. The LZV200 then switches off all
other amplifiers and communicates this to all connected input devices
via the XpressNet.
Read more about the use of additional amplifiers in the section 6
starting on page 42.
The terminal E of the LZV200 can also be used for the connection of a
"panic emergency shutdown push-button". Install one or several push-
buttons at the edge of your layout and connect them with the terminals
M and E.
If a crash is about to happen on the layout, simply press this
emergency shutdown push-button. The LZV200 changes over to
"emergency shutdown" and switches off the operation on the layout.
The manual controls will show a corresponding message. Now you
have time to solve the "precarious" situation. Afterwards, release the
emergency shutdown on the manual control and resume operation.

5.6 Feedback bus: terminals R,S

The feedback bus is connected to the terminals R and S. The LZV200
queries the status of point settings or track occupation detectors via
this cable which needs to be twisted. To this end, switch decoders
LS100 and / or feedback modules LR101 are connected to the
feedback bus.
Use twisted cables for this. Do not on any account lay out the
feedback bus in multiwire cables with or parallel to live cables, e.g. the
track connections J and K or the power lines U and V or supply mains.
This could lead to malfunctions in the operation of the feedback bus.
