or reflection-related measurement errors
For retro-reflectors in the background less than 1 m from the protective field boundary,
the supplement Z
R
is 200 mm.
Supplement Z

due t
o lack of ground clearance
This supplement is necessary, because, generally, a person is detected above the foot
and the braking process cannot take account of the length of the foot in front of the
point of detection. A person’s foot could be injured if a vehicle has no ground clearance.

Protective field length
The lump supplement for ground clearance under 120 mm is 150 mm. This supple‐
ment ma
y be reduced further in individual cases. The actual supplement required
based on the ground clearance of the vehicle can be read from the following graph:
