WLA26x-xxxxxx3xAxx with teach-in button:
There must not be any objects located between the WLA26 and the reflector. The sensi‐
tivity is reduced by pressing the teach-in button (approx. 1-3 seconds). This primarily
suppresses false switching to extremely depolarizing objects. The sensing range is also
reduced, and therefore the operating reserve as well. Lead an object into the path of
the beam. The yellow display LED goes out, meaning the object is detected and the
setting is correct.
