Banner AG4 Series Safety Laser Scanner3.3 Mechanical Installation ConsiderationsMany factors influence the layout of the Scanner’s mechanical installation. For stationary applications, these includeseparation (safety) distance, supplemental safeguarding (hard guarding), unmonitored areas (shadows or areas behindthe Scanner), adjacent Scanners, and the height of the Protective Field (in horizontal applications). In addition, mobileapplications must take into account the stopping performance and distance of the mobile vehicle which the Scanner iscontrolling.3.3.1 Unmonitored AreasWARNING . . . UNMONITORED AREASThe area behind the Scanner and near it, on either side (shown in the following figure) is not monitored. Unmonitored areas can create an accessroute to the hazard or a blind zone where a person cannot be detected. Make sure that this unmonitored area is minimized, so that no one canaccess this area undetected (by recessing the Scanner into the machine, using supplemental safeguarding, or using mechanical barriers toprevent access). Failure to do so could result in serious bodily injury or death.Behind and To the Sides of the ScannerThe area behind and on either side the Scanner is not monitored (see Figure 3-1, #3). It must not be possible to walk inunmonitored areas or otherwise access them. This can be accomplished by recessing the Scanner into the machine,using supplemental safeguarding, or using mechanical barriers to prevent access. If there is a possibility that theScanner could be used as a climbing aid or standing surface, use a physical cover set at an angle over the Scanner (seeFigure 3-2, #3).Special attention to these areas must be addressed in vertical Protective Field applications so that the resolution at theedges of the Protective Field does not increase. If an increased resolution cannot be prevented, then the worst-caseresolution must be used to determine the Dpf (U.S. formula) or the C factor (European formula) in the safety distancecalculation (see Sections 3.3.4 and 3.3.5).1 Scanner2 PF3 Unmonitored areaFigure 3-1. Protective Field – Unmonitored AreasWARNING . . . POSITION COMPONENTS CAREFULLYThe Scanner must be positioned such that the hazard cannot be accessed by reaching over, under, around or through the sensing field. Additionalguarding may be required; see Safety distance, Section 3.3.4-5, Pass-Through Hazards, Section 3.3.6, and Supplemental Safeguarding, Section3.3.8.Buy: www.ValinOnline.com | Phone 844-385-3099 | Email: CustomerService@valin.com |
