Information LV103
No radio interference suppression capacitor may be
installed in the track system. This capacitor is necessary
only for the interference suppression in conventional
operation. If used with the Digital plus system, however, it
would distort the data format and interfere with the fault-
free transmission of data.
Important:
A mixed digital operation using overhead and track lines is not
permitted. In this type of operational mode, the installed locomotive
decoder can be destroyed by overvoltage if the locomotive is sitting on
the track in the wrong direction (which might be the case e.g. after
having driven through a terminal-loop)! We recommend operation
using track pick-up, because the reliability of contact (and therefore
the transmission of digital signals to the locomotive decoder) is
substantially greater than it is when operating
with overhead lines.
It is absolutely necessary that the electric circuits of all amplifiers are
of the same polarity. Thus, terminal J of one and terminal J of the next
amplifier must be connected to the same side of the track in question.
Otherwise short-circuits will occur when driving over sectioning points.
If you have several supply areas on your model railway layout, you will
have to set the track voltage (output voltage) for the amplifiers in use
to the same value (see Section 6).
6.4 Connection to the command station: terminals
C,D,E
The amplifier LV103 receives the data format from the command
station via the terminals C and D (LZ100, LZV100, LZV200). The
terminals are connected to the terminals of the other amplifiers, which
have the same name. We recommend the use of a twisted cable.
If terminal E of the amplifier is connected to terminal E of the
command station, the amplifier will communicate an overload or a
short-circuit to the command station. The command station then
switches off all other amplifiers and communicates this to all
connected input devices via the XpressNet.
Terminal E is also used for transmission from the built-in global
Railcom detector to the LZV200.
