Supply the power to the sensor and adjust the optical axis and the sensitivity as follow ; Adjustment Optical axis adjustment Optimal position Sensing target MIN. MAX. Mount this unit at center position where the stability indicator turns ON as moving the unit toward right or left, up or down. A-24 1. When sensing the object, set the sensitivity adjustment VR in stable Light ON area(orange: Light On, green: Dark On) as shown ` Operation mode'. 2. The sensitivity should be adjusted depending on a sensing target or mounting place. 3. Set the target at a position to be detected by the beam, then turn the adjustment VR until position where the operation indicator turns ON from min. position of the adjustment VR. 4. Take the target out of the sensing area, then turn the adjustment VR until position where the the operation indicator turns ON. If the indicator dose not turn ON, max. position is . 5. Set the adjustment VR at the center of two switching position , . The sensing distance indicated on specification chart is for 200x200mm of non-glossy white paper. Be sure that it can be different by size, surface and gloss of target.
