14 VEGASCAN 850
1) Sensor cables should be screened. Grounding of
the cable screens at both ends is recommended.
However make sure that no earth compensation
currents flow via the screens (see chapter "5.1
Connection, connection cable and screening“).
Earth compensation currents can be avoided by
potential equalisation lines or if the cable screen is
grounded at both ends - by connecting one end via
a capacitor (e.g. 0.1 µF; 250 V) to earth potential.
Configuration A
Up to 15 sensors via one two-wire cable on VEGASCAN 850
• Two-wire technology, 15 sensors with power supply and digital output signals via one two-
wire cable on VEGASCAN 850 possible. However, it is better to wire in groups of five as in
configuration B and C.
