3 Install Your Scanner
A horizontal Safety Zone is considered to be 30° or less from a level floor or walking surface.
1. Determine the area to be safeguarded by the scanner.
2. Determine whether to install the SX with or without a Banner mounting option.
3. Determine the size and coverage of the Safety Zone and Warning Zone (if used) depending on: physical location of
the scanner installation, and the minimum safety distance or the stopping distance of the mobile vehicle.
See
Minimum Safety (Separation) Distance for Stationary Applications
on p. 38.
4. Determine the restart operating mode (manual or automatic reset). See
Automatic or Manual Start/Restart
5. If Manual restart is used, determine the location for the reset switch, see the reset switch location section of the
manual.
6. Determine if a Zone Set switchover is required and identify the conditions for use.
7. Configure the SX with the configuration software.
8. Record the SX configuration and the Safety/Warning Zone dimensioning. This document should identify and be
signed by the individual(s) responsible for the configuration and be included with the machine documentation.
9. For stationary applications, it is recommended to mark the perimeter of the Safety Zone(s) on the floor as an
awareness means for individuals in the area. For mobile applications, it is recommended that the diagram be readily
available for review.
10. If required, install means to protect the SX from physical damage, sources of optical interference (e.g. other
scanners), or prevent the SX from being used as a climbing aid. Ensure that these means do not impair the SX's field
of view.
3.1 Safety Zone (SZ) and Warning Zone (WZ) Considerations
•
Ensure the dimension (size) and coverage of the Safety Zone can detect an intrusion and allow the scanner's OSSDs
to stop the dangerous movement before personnel can access the hazard. (See
Distance for Stationary Applications
on p. 34 and
Minimum Distance D (Safety Zone Length) for Mobile Applications
on p. 40.)
•
Ensure that access to all hazards is not possible for all Zone Set switchover applications.
•
Ensure that safety distance and stopping distance calculations incorporate all factors that can effect response time,
including:
◦
The additive effect of all device response times, such as the scanner, UM-FA-… safety module, and all
machine control elements (FSDs and/or MPCEs).
◦
Add the appropriate response time values to account for any reasonably foreseeable machine stop time
degradation, such as due to brake pad wear.
•
Ensure that the Safety Zone adequately covers all access routes that may lead to the safeguarded hazard or
supplemental guarding may be required (see
on p. 27).
•
Ensure that the safeguarded hazard(s) cannot be accessed because of the effect of "shadowing" within the Safety
Zone by adding supplemental safeguarding, such as additional scanners.
•
Observe the lateral tolerance when dimensioning the Safety Zone (e.g. do not use needle or cone-shaped boundaries
to define the separation (safety) distance; cone-shaped boundaries rely on less accurate, angular resolution
measurements).
•
Consider and resolve any other application factors that might require an increase in the separation (safety) distance
or stopping distance. These factors should be identified via the risk assessment process.
•
Determine if the reference points (surface) monitoring function is required (especially in vertical applications). This
function prevents unintentional misalignment and deliberate manipulation of the SX (see
3.2 Mechanical Installation Considerations
Many factors influence the layout of the SX’s mechanical installation. For stationary applications, these include separation
(safety) distance, supplemental safeguarding (hard guarding), unmonitored areas (shadows or areas behind the SX),
adjacent SXs, and the height of the Safety Zone (in horizontal applications). In addition, mobile applications must take into
account the stopping performance and distance of the mobile vehicle the SX is controlling.
