4.3.8.2 Protective field width
The protective field must be wide enough to cover the width of the loaded vehicle with
supplements f
or measurement error and the lack of ground clearance. When calculat‐
ing the protective field width, the impact of turning must be considered separately.
Supplement Z
R
for reflection-based measurement errors
All devices: If there is a retroreflector in the vicinity of the protective device (distance
of the retroreflector from protective field ≤ 6 m), you must take the supplement Z
R
=
350 mm into account.
