L. SWITCH Dark- mode D. L. SWITCH - mode: LIGHT (L) Dark- mode: DARK (D) The operation indicator (red LED) and stability indicator (green LED) show the levels of light intensity as described in the figure below. After aligning the optical 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. Stable light reception range Stable light blocking range STB (green) - mode OP.L (red) Dark- mode Operation level x. Operation level Operation level x 0.8 The red LED (OP.L) is the operation indicator. In the L. (-) 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. The stability output can be used to check for reduction of the light intensity level along with any change in the operating environment or operation over time or to perform initial check of the operation. When two consecutive detections have occurred with the intensity of light detected exceeding the operation level but not reaching 0 % of the level (range allowing stable operation), the stability signal is output when the control output is deactivated. - mode Dark- mode Received light intensity 0% 00% Operation level Sensitivity adjustment (for diffuse-reflective type) (Adjustment for - 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 (SENS.) gradually and find the point at which the operation indicator (red LED) is illuminated (Point A). ()Remove the object, turn down the sensitivity adjustment volume gradually from MAX. and find the point at which the operation indicator (red LED) goes out (Point B).
