Single-Point Light SET
• Useful for clear object detection and other applications with small variations in contrast.
• Sets a switchpoint at 8 (clear), 16 (medium) or 32 (dark) percent below the signal from the
retroreflector.
• Switchpoint position is selectable using the “+” and “-” buttons. Select 8, 16, or 32
percent (Switchpoint Selection).
• Sensor must be aimed at the reflector during the SET process. All conditions darker than
the switchpoint condition result in ON output (Dark Operate). Output ON and OFF conditions
can be reversed by changing Light/Dark Operate in SETUP mode (factory setting: Dark
Operate).
