OPERATING INSTRUCTIONS
Cause
Sensor is still ready for oper‐
ation, but the operating condi‐
tions are not ideal
Excessive background remis‐
sion
Sensitivity is set too low or dis‐
tance between the sensor and
the object is too long
Remission capability of the
object is insufficient

Measures
Check the operating condi‐
tions: Fully align the beam
of light (light spot) with the
object. / Clean the optical sur‐
faces . / Check sensing range
and adjust if necessary.
Check changes to the back‐
ground. Reduce the sensitivity
of the sensor or use sensors
with background suppression
Increase the sensing range,
take note of the distance
between the sensor and the
background
Increase the sensing range,
take note of the distance
between the sensor and the
background
