When two consecutive detections have occurred with the intensity of light detected exceeding the operation level but not reaching % of the level (range allowing stable operation), the stability signal is output when the control output is deactivated.

Indicators Light-/Dark- selector switch The operation indicator (red LED) and stability indicator (green LED) show the levels of light intensity as described in the figure below. fter aligning the optical axis and adjusting the sensitivity, use a detection object to block and unblock the light beam several times to make sure that the sensitivity level is in a range that allows stable activation and deactivation. Setting the sensitivity in a range allowing stable operation achieves higher reliability against changes in the operating environment generated after the sensitivity is set. ST.
