Safety zone selected so that
cutting behind is not possible
If the undetected presence in front of the AGV cannot be prevented by the design of the safety zone, the
following applies:
•
The AGV must be in restart interlock mode (manual restart)
•
The width of the no-detection accessible zone which is directly in front of the AGV must be smaller than 35
mm (1.38 in) (for a safety distance up to 3 m (9.84 ft). For higher safety distances, the gap must be zero.
IMPROPER RESTART MODE CONFIGURATION
To avoid a dangerous restart of the AGV after exiting of the safety zone, the system control must be configured
in the restart interlock mode setting (manual restart) using a restart hold time of at least 2s (see start menu in
software manual).
Failure to comply with these instructions could result in death or serious injury.
IMPROPER PERSONNEL PROTECTION
Install the safety equipment to prevent personnel to travel with the AGV. Use additional safety equipment if
necessary.
Failure to comply with these instructions could result in death or serious injury.
