Supply the power to the sensor and adjust the optical axis and the sensitivity as follow ; When using photoelectric sensors closely over two units, ● Adjustment it may result in malfunction due to mutual interference. 1. When sensing the object, set the sensitivity adjuster in When installing the product, tighten the screw with a stable Light ON area (orange: Light ON, green: Dark tightening torque of 0.5N.m. ON) as shown ‘ Operation mode’. ● Optical axis adjustment 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, Optimal then turn the sensitivity adjuster until position ⓐ where position Sensing the operation indicator turns ON from min. position of the target sensitivity adjuster ⓑ 4. Take the target out of the sensing area, then turn the MIN. MAX. sensitivity adjuster until position ⓑ where the operation indicator turns ON. If the indicator dose not turn ON, max. position is ⓑ.
