7 Troubleshooting
Table 7: Fault diagnosis
Display, error situation Cause Measure
Green LED does not light up No voltage or voltage below
the limit values Check the power supply,
check all electrical connections
(cables and plug connections)
Green LED does not light up Voltage interruptions Ensure there is a stable power
supply without interruptions
Green LED does not light up Sensor is faulty If the power supply is OK,
replace the sensor
Yellow LED flashes (only
briefly) Teach-in mode Check the teach-in mode
Yellow LED flashes quickly
(only briefly) Teach-in button lock active Deactivate the button lock
Yellow LED lights up, no object
in the path of the beam Distance between the sensor
and the background is too
short Reduce the sensing range, see
teach-in
Object is in the path of the
beam, yellow LED does not
light up Distance between the sensor
and the object is too long or
sensing range is set too short Increase the sensing range,
see teach-in
