Light Set
Use Light SET for low contrast applications. Use either the push button or
remote input wire procedure to configure the sensor.
Example Applications For Offset Percentages
8%
Recommended for very low contrast applications with stable environmental
conditions.
16%
Recommended for most clear object detection applications in typical machine
industrial environments.
32%
Recommended for high contrast detections such as brown or green bottles, or
opaque objects. This setting tolerates environmental challenges such as
vibrations and dust build-up.

Clear the light path to
the reflector.
Press and hold the push
button 2 to 4 seconds.
LIGHT SET Configuration Accepted
Green LED Indicator: Flashes 3 times.
Green and Amber LED Indicators: Acceptance flash - both LEDs flash 5 times
rapidly in unison.
The sensor returns to Run mode with the new settings.
LIGHT SET Configuration Not Accepted
If there is not enough return signal, the sensor will perform in DARK SET indicated
by the green and amber LED indicators flashing in unison 2 times followed by the
green and amber LED indicators flashing rapidly in unison 5 times.
Dark Set
Dark SET (maximum operating range) is the factory default setting and
provides maximum sensing range, ease of alignment, and reliable
detection of opaque objects. Dark Set provides a fixed threshold
whenever the sensor is taught an obstructed view.
NOTE: The sensor's light spot is made brighter for 60
seconds to assist in aligning the sensor to the reflector.
This is particularly useful for long range applications.
