Reduced Resolution increases the minimum diameter of an
object that the light screen can reliably detect anywhere within
its defined area. Reduced Resolution is generally used to allow
one or more objects (usually workpiece materials) to move
through the defined area, at any point, without tripping the
OSSD safety outputs.
Selecting two-beam Reduced Resolution will reduce the overall
minimum object sensitivity, which allows multiple objects to
move through the defined area (see Section 3.4.2). The effect
is that every two consecutive beams (except for the sync beam)
can be blocked, but not cause the OSSDs to turn OFF. This is
also called “Multiple-Point Floating Blanking.”

Resolution directly affects the minimum allowable distance
between the defined area of a light screen and the nearest
hazard point (separation distance, see Section 3.1.1). The
green status indicator on the receiver flashes when Reduced
Resolution is enabled. The ignored object size and resultant
Reduced Resolution are listed in Section 3.4.2.
Status indicators on both the emitter and receiver are clearly
visible on each sensor’s front panel.

1.4.7 Status Indicators
Bi-color red/green Status indicator – shows whether power is
applied, and whether the emitter is in RUN mode, TEST mode,
or Lockout condition.
1-Digit Diagnostic Display – indicates specific error or
configuration conditions.
Bi-color red/green Zone indicators – show status of a group of
beams:
- aligned and clear (green ON), or
- blocked and/or misaligned (red ON), or
- fixed blanked area (flashing green).
Yellow Reset indicator – shows System status:
- RUN mode (ON) or
- waiting for a reset (flashing).
Bi-color red/green Status indicator – shows System status:
- Reduced Resolution enabled (flashing green),
- outputs are ON or OFF (green ON or red ON), or
- the System is in Lockout condition (flashing red).
3-Digit Diagnostic Display – indicates specific error,
configuration conditions, or total number of blocked beams.
