Banner AG4 Series Safety Laser Scanner
3.4.4 Mobile Side Guarding on AGVs (Vertical Protective Fields)
If the Additional Side Distance Z cannot be complied with or if additional safeguarding is otherwise required, additional
AG4 vertical Protective Fields can be used (see Application Guide p/n 147900).
The Protective Field must be configured so that the mobile vehicle can come to a complete stop before a collision can
occur. In the case of vertical Protective Fields on mobile vehicles, the Scanner is typically mounted facing down at a
slight tilt (such that the lower edge of the Protective Field extends a distance of Z as described above, if possible). To
determine the dimension to the edge of the side of the Protective Field use the Minimum Distance (D) formula described
above.
The Scanner should be configured with a resolution of at least 150 mm to detect the torso of an individual (i.e. ―Body
protection –danger zone guarding‖). The risk assessment should determine if a smaller resolution is necessary.
Table 7. Vertical Guarding Application
Configuration Description
Vertical Guarding – Body Detection
(Body protection –danger zone guarding)
Vertical Protective Field - stationary
Resolution = 150 mm,
Maximum Protective Field range: AG4-4E = 4 m (13.2'); AG4-6E = 6.25 m (20.6')
Start/Restart Interlock selectable (Manual or Auto reset)
Default = Start/Restart Interlock enabled (Manual)
Note: Reference contour (surface) monitoring function is manually configured.
If it is not possible to completely safeguard the vehicle (including trailers, protruding or overhanging loads, etc.), during
the full length of travel (including curves), then additional safeguarding (e.g., additional Scanners or bumper/edge
switches) must be used.
