Distance from walls
The availability may be impaired if the protective field stretches as far as a wall or a
different object. So, a space between the protective field and the object is required. A
distance of the TZ value is recommended to ensure availability. (TZ = tolerance zone of
the safe multibeam scanner,

Mobile hazardous area protection
In mobile hazardous area protection, the safe multibeam scanner is mounted with
a horizontal scan plane, e.g., on an automated guided vehicle. The safe multibeam
scanner protects the hazardous area created by the vehicle’s movement.
The safe multibeam scanner detects a person’s legs. The protective field is parallel to
the direction of approach.
