This means the sensitivity can be adjusted on only a single photoelectric sensor, and then the adjusters on the other photoelectric sensors can be set to the same scale position. There is no need to adjust the sensitivity of each photoelectric sensor individually. Steps Step 1 Step 2 Step 3 Function Determine Position A Determine Position B Adjust to optimum setting Sensing condition Photoelectric sensor Photoelectric sensor Photoelectric sensor Target Target Target Sensitivity adjuster Min Indicators OFF OFF ON STABILITY (green) Max Min Max LIGHT (red) Place target at the desired sensing distance. Set sensitivity adjuster to the minimum scale position and gradually increase sensitivity by turning the sensitivity adjuster clockwise until the Light Incident indicator (red LED) turns ON. Position A designates the point at which the LED has turned ON. OFF STABILITY (green) Max OFF ON LIGHT (red) Remove the target. Starting from the maximum scale position, gradually decrease sensitivity by turning the sensitivity adjuster counterclockwise until the Light Incident indicator (red LED) is OFF. Position B designates the point at which the LED has turned OFF. 10 Min STABILITY (green) LIGHT (red) Set the sensitivity indicator to the position between Positions A and B (in some cases, Positions A and B are opposite of the above example). The photoelectric sensor will then work normally if the stability indicator (green) is lit with and without the target. If it is not lit, stable operation cannot be expected, in which case a different detection method should be applied. E3SB E3SB NOTE: DIMENSIONS SHOWN ARE IN MILLIMETERS.
