LED/fault pattern
Cause
Measures
Yellow LED flashes
Sensor is still ready for oper‐
ation, but the operating condi‐
tions are not ideal
Check the operating condi‐
tions: Fully align the beam
of light (light spot) with the
reflector. / Clean the optical
surfaces (sensor and reflec‐
tor)./ If the potentiometer is
set to the max. sensing range:
Reduce the distance between
the sensor and the reflector,
and check the reflector type /
Reflector is not suitable for
the application in question
(we recommend only using
SICK reflectors) / Check sens‐
ing range and adjust if neces‐
sary. / Distance between the
sensor and the reflector is too
long
Signal interruptions when
object is detected
Depolarizing property of the
object surface (e.g., tape),
reflection
Reduce sensitivity or change
the position of the sensor
