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 p. 14):
•
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 p. 15).
• 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.
2.3.5 Applications with Master and Remote Scanners
In applications where you need to monitor several zones that are not visible from just one point, use more than one scanner.
However, there may be just one safety function, for example dangerous movement that must be stopped when something is
detected inside the area.
The SX Laser Scanner can effectively solve this situation. Up to four scanners can be easily connected to each other through
an Ethernet-based safe communications bus, working as a single system (cascading the scanners).
Only the Master Unit receives power, has inputs and outputs onboard, and must be connected to a PC to configure the entire
system.
The Remote Units (cascaded units) are connected to the Master with a single cable that also provides them with power. The
synchronization of up to four (4) scanners is an integrated function. There is no need for extra external control units.
2.4 Operating Features
The Banner SX Series 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
• Cascading up to four scanners in one chain
• Interfacing encoder inputs in AGV applications for assistance in selecting Zone Sets
For more information, see Configuration Instructions on p. 67.
