Sensor with potentiometer:
The sensitivity (sensing range) is adjusted with the potentiometer (type: 5-turn).
Clockwise rotation: sensitivity (sensing range) increased; counterclockwise rotation:
sensitivity (sensing range) reduced. We recommend placing the switching state in
the object, e. g., see graphic F. Once the sensitivity has been adjusted, the object is
removed from the path of the beam. The switching output changes (see graphic C).
The sensor is adjusted and ready for operation. Refer to graphics C and G to check
the function. If the switching output fails to behave in accordance with graphic C,
check application conditions. See section Fault diagnosis.
