In case of 2-color type, fasten it at the locationwhere the indicator light color changesfrom red to green.Position wherelight turns ONStep 3) Slide the auto switch in the direction of the arrow until the indicator lightilluminates.Step 4) Slide the auto switch a further distance in the direction of the arrow until theindictor light goes out.Position tobe secured0.3 to 0.5 mmStep 5) Move the auto switch in the opposite direction and fasten it at a position 0.3 to0.5 mm beyond the position where the indicator light illuminates. In the case of 2-colorindicator type, fasten it at the location when the indicator light color changes from redto green.Position where light turns ONPosition to be secured0.3 to 0.5 mm486Note 1) It is recommended that gripping of a workpiece be performed close to the center of the finger stroke.Note 2) When holding a workpiece close at the end of open/close stroke of fingers, detecting performance of the combinations listed in the abovetable may be limited, depending on the hysteresis of an auto switch, etc.
