The sensor must be disposed of according to the applicable country-specific regulati‐
ons. Efforts should be made during the disposal process to recycle the constituent ma‐
terials (particularly precious metals).

Check the operating conditi‐
ons: Fully align the beam of
light (light spot) with the ob‐
ject. / Clean the optical surfa‐
ces . / Readjust the sensitivity
(potentiometer) / Check sen‐
sing range and adjust if ne‐
cessary; see graphic F. /
