SICK WTB4F SingleLine - Disassembly and Disposal; Maintenance; Technical Specifications

LED/fault pattern Cause Measures
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
No object in beam path, no
output signal
Test input (Test) is not con‐
nected properly
Check connection of the test
input. When using female cable
connectors with LED indicators,
make sure the test input is
assigned correspondingly.
