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. (This output is not available with the PNP output types of the Mini-G Series.)

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.

The orange LED (OP.L) is the operation indicator. In the L. (Light-) mode, the indicator is illuminated when a certain amount of light is detected. In the D. (Dark-) mode, the indicator is illuminated when a certain amount of light is not detected. Sensitivity adjustment (for Light- mode) (djustment for Light- mode) When any light-reflecting object is in the background () Place the object to be detected in a given position, turn up the sensitivity adjustment volume () gradually and find the point at which the operation indicator (red LED) is illuminated (Point ). () Remove the object, turn down the sensitivity adjustment volume gradually from MX. and find the point at which the operation indicator (red LED) goes out (Point ).
