4 Align the sensor with the object. Select the position so that the red emitted light
beam hits the center of the object. You must ensure that the optical opening (front
screen) of the sensor is completely clear [see Graphic E/F]. We recommend mak‐
ing the adjustments using an object with a low remission.

5 Sensor which it is not possible to set: The sensor is set to factory settings 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.

Sensor with potentiometer:
The sensing range is adjusted with the potentiometer (type: 270°). Clockwise rota‐
tion: sensing range increased; counterclockwise rotation: sensing range reduced.
We recommend placing the switching state in the object, e.g., see graphic F. Once
the sensing range has been adjusted, the object is removed from the path of the
beam, which causes the background to be suppressed and the switching output to
change (see graphic C).
The optimum 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 object position and the set switching point. If no LEDs or only the red
LEDs light up, the object is positioned behind the set switching point and cannot be
detected. The first yellow LED lights up when the object is in the set switching
point. The green LEDs light up when the object is between the sensor and the set
switching point. The closer the object is to the switching point, 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.
