3, check the application conditions.
Sensing range adjustment
WLA12Lx-xxxxxx3xAxx with teach-in button:
The sensitivity and operating reserve are optimized by pressing the teach-in button until
the yellow LED flashes (approx. 1-3 seconds). Lead an object into the path of the beam.
The yellow LED goes out, meaning the object is detected and the setting is correct.
