Low-Contrast SET – Model QS30LLPC
• Sets a switchpoint at 35 percent below the signal from the retroreflector.
• Useful for small object detection and other applications with small variations in
contrast, such as yarn- or thread-break applications.
• 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).
Manual Adjust – Low-Contrast SET
During RUN mode, adjusts switchpoint up or down via “+” or “–” push buttons.
• Each push button “click” adjusts the switchpoint up by 5 percent of the signal from
the reflector or down by the same increments.
• The lighted bargraph LEDs move to reflect the increase or decrease in excess gain.
• LEDs #7 and 8 flash when maximum gain is achieved; LEDs #1 and 2 flash when
minimum gain is achieved.
If the target object does not cause the output to change state, press the “–” button to
decrease the gain, making the sensor more sensitive to small signal changes.
