Sensing range adjustment
The sensing range is adjusted relative to the background with the potentiometer.
Clockwise rotation: Sensing range increased; counterclockwise rotation: Sensing range
reduced. Turn the potentiometer clockwise until the yellow LED lights up. Afterwards,
only turn the potentiometer counterclockwise as far as is needed so that the yellow LED
no longer lights up. When an object is moved into the path of the beam, the yellow LED
must light up. If the yellow LED does not light up during object detection, repeat the
adjustment process, or reduce the distance between the sensor and background and
then repeat the adjustment process.
Please refer to the enclosed "IO-Link photoelectric sensors" operating instructions for
information about adjusting the IO-Link sensing range.
The sensor is adjusted and ready for operation.
