Figure 9. Mobile area guarding with side vertical guarding
In addition to the typical considerations for mobile area guarding (see
Mobile Area Guarding on Transfer Carts/Trolleys and
Automated Guided Vehicles (AGVs)
on page 13):
• Select 70 mm resolution for torso detection.
• Set the leading edge of the vertical Safety Zone no shorter (smaller) than the corresponding horizontal Safety Zone
(assuming that the response times and safety distances are equal).
• Position the vertical Safety Zones at a slight angle so that the lower Safety Zone edges protrude over the vehicle
width by the amount of the additional distances Z

when required (see
Vertical Guarding with
Reference Point Monitoring
on page 14).
• The
configuration of reference points, as with other vertical guarding applications, is not required, because the
approach of the individual is detected by the edge of the Safety Zone and not the plane. As with the horizontal
Safety Zones, the vertical Safety Zone must be checked (verified) on a periodic basis.
•
Minimize crushing/trapping hazards by using supplemental safeguarding, such as by preventing access (e.g.,
fencing) or by causing the individual to be detected by the leading edge of the horizontal Safety Zone.
2.4 Operating Features
The Banner SX5 Safety Laser Scanner models described in this instruction manual feature several functions. Configuring
some of these functions must be accomplished by a
Qualified Person to ensure that personnel who are exposed to
potentially dangerous situations are adequately protected. Features include:
• Selecting automatic or manual start/restart
• Configuring the response time
•
Setting the Warning and Safety Zones
• Defining a Warning output
• Configuring
a muting evolution
For more information, see
Configuration Instructions
on page 53.
2.5 Reference Points (Surface) Monitoring
The reference points (surface) monitoring function prevents unintentional misalignment and deliberate manipulation of the
SX5.
If the configuration contains reference points, the SX5 monitors both the Safety Zone (for intrusions) and the reference
points (for position). If the distance between the scanner and the reference surface (point) changes from the configuration
(greater than the assigned tolerance), the SX5 detects the change and switches the OSSDs to OFF.
The design of the installation and the risk assessment must identify the need and use of the reference points (surface)
monitoring function. In horizontal applications, this function ensures that the safeguarded area does not change due to the
SX5 moving or changing position because of an impact, vibration, or poor maintenance practices. In a vertical application,
the position of the Safety Zone has a critical effect on the separation (safety) distance. If there is an angular movement of
the SX5 that causes the Safety Zone to be positioned closer to the hazard, an individual could access the hazard before the
machine can stop.
