Zones
A zone is a range of lenses in the transceivers that are blanked with specific
conditions. A maximum of eight zones can be specified. The zones must be used
in order and must not be skipped. The lenses must be used in order, but lenses can
be skipped. Each zone can be:
• Fixed blanking
• Floating blanking
• Reduced resolution blanking
The following rules apply to specifying zones:
• Zone definition begins with the lowest lens; the lens closest to the
connection plug-in.
• Zones cannot overlap.
• Each zone must be a contiguous set of lenses.
• Each zone can be either fixed, floating, or reduced resolution.
• A non-blanking area is allowed between zones or at either end of the
transceiver. This area is not considered a zone.
• Non-blanked areas can be assigned either 1) normal operation, 2) reduced
resolution one object or 3) reduced resolution two objects.
• Only one of the synchronization beams can be blocked (either at the top or
the bottom, but not both top and bottom).
Figure 121 on page 160
shows an example with a finger resolution light curtain.
Zone 1 applies fixed blanking (object always present and remains stationary)
between lens 1 and 2. Zone 2 applies floating blanking (object can move but must
always be present) between lens 3 and 14. Zone 3 applies reduced resolution
between lens 19 and 30. Lenses 31…32 are used for synchronization, and normal
operation (finger resolution) applies. The area from lens 15…18 is also normal
operation (finger resolution).
