5 Sensor with potentiometer:
The sensitivity is adjusted with the potentiometer (type: 270°). Clockwise rotation: operating
reserve increased; counterclockwise rotation: operating reserve reduced. Adjustment for
detecting transparent objects (> 20% damping): Place object between sensor and reflector.
Reduce the sensitivity until the LED indicator goes out. Once the object is removed, the LED
indicator must light up again. If the LED indicator does not light up again, check the applica‐
tion conditions.
The sensor is adjusted and ready for operation. Refer to Graphics C and G to check the func‐
tion. If the switching output fails to behave in accordance with Graphic C, check application
conditions. See section Fault diagnosis.
