The following graphic shows the distance from the interfering devices (D
do
) according to the
operating distance (D
op
) of the couple ( TXA – RXA ).
Fig. 12
The following table shows, for convenience, the values of the minimum installation distances
relative to some operating distances:
Operating distance
(m)
Minimum installation distance
(m)
3 0,3
6 0,4
10 0,5
19 0,6
WARNING: the interfering device (TXB) must be positioned at the
same Ddo distance, calculated as shown above, even if closer to
TXA respect to RXA.
When several safety devices have to be installed in adjacent areas, the interference between
the emitter of one device and the receiver of the other must be avoided.
