3 Prohibited area 3: non functional
Example: 10 sensors (MF) VarioGard 3200 CAT have the bus load 25 (10x2.5). If the total length of all NYM cable sections is shorter than
650 meters, the system is always functional. If you distribute the bus loads approximately evenly, the total length may measure 1000 meters.
The spacing would on average be (1000 m / 10 MF) = 100 meters.
