Protective Field Width
The width of the protective field must cover the width of the vehicle and the
supplements for the measurement error and the lack of ground clearance.
Calculate the Protective Field Width S

See EN ISO 13855. Calculate the protective field width S

with the formula:

ATTENTION: Mount the SafeZone Mini device such that the scan plane is at a
maximum height of 200 mm (7.87 in.).
In this way, persons lying down are reliably detected. Tilting the protective
field so objects with a diameter of 200 mm (7.87 in.) are not detected, is not
allowed. We recommend aligning the scan plane horizontally at 70 mm
(2.76 in.).
TIP To produce the optimal scan plane, you can also mount the SafeZone Mini
device reversed.
