5 Sensor which it is not possible to set: The sensor is set to factory settings and rea‐
dy for operation.
Refer to graphics C and G to check the function. If the switching output fails to be‐
have in accordance with graphic C, check application conditions. See section Fault
diagnosis.

Sensor with potentiometer:
The sensitivity (sensing range) is adjusted with the potentiometer (type: 270°).
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 optimum alignment and setting can be achieved and checked using the signal
strength light bar on the back of the sensor. The LEDs on the signal strength light
bar light up in relation to the signal strength of the sensor's received light. If no
LEDs or only the red LEDs light up, the sensor is either receiving no signal at all or
is receiving insufficient signal to switch the output. As soon as the minimum swit‐
ching threshold is attained, the first yellow LED lights up, and the output switches.
The green LEDs display the operating reserve. The better the operating reserve (re‐
ceived light), the more green LEDs will light up (see graphic F).
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.
