Reduced Resolution allows objects of a certain maximum size to
interrupt the defined area without causing a Trip condition (i.e.,
the OSSDs turn OFF). Use Reduced Resolution only when
necessary. In Reduced Resolution applications, the separation
distance always increases due to the larger depth penetration
factor (Dpf). In either case see Section 3.1.1 to determine
separation distance.
With 2-beam Reduced Resolution enabled, any two
consecutive beams, (except for the sync beam), can be
blocked without causing a stop condition. Thus, multiple “holes”
are created in which 14 mm systems will “see” a 30 mm object
and ignore an 8.5 mm object. Similarily, 30 mm systems will
“see” a 60 mm object and ignore a 17 mm object. See Figure
4-1 for DIP-switch configuration. During operation, the Status
indicator flashes Green when Reduced Resolution is enabled.

One or multiple areas within an EZ-SCREEN sensor pair may
be blanked out. The minimum number of beams between two
blanked areas is one. Any beam other than the sync beam may
be blanked. All beams of a fixed blanked area must stay blocked
at all times (after the fixed blanking configuration mode has been
exited), in order for the OSSDs to stay ON.

completely filled by the blanked object or the separation distance
must be increased to account for the larger resolution (see Section
