DISASSEMBLY AND DISPOSAL
Cause
The sensing range distance is
too large
Distance between the sensor
and the object is too long or
sensing range is set too short
Test input (Test) is not con‐
nected properly

Measures
Reduce the sensing range
Increase the sensing range
Check connection of the test
input. When using female cable
connectors with LED indicators,
make sure the test input is
assigned correspondingly.
