Connecting the track sections
The busy status can only be reported trouble free, if one conductor is isolated at both ends of
each section to be monitored:

3-rail systems: centre conductor or both rails

2-rail systems (analogue): "-" rail

2-rail systems (digital): one of the two rails
Please note that, due to the principle, in analogue 2-rail systems (DC systems) only vehicles
are detected that enter the track section in the direction marked as "direction of travel" in the
connection diagram.

Monitoring of switched-off track sections
Track sections that are to be switched off during operation (e.g. in a staging yard) can also be
monitored with the GBM-8.2. For this purpose, a resistor with a value < 1.5 kW must be
installed in the supply line to the track section concerned in such a way that it bridges the
switch in the switched-off state.
