7.2 Horizontal adjustment of the detection angle

If there is an obstacle in the way of the

detection beams, they can be horizontally

offset by 3°.

when both the upper and lower beams are

broken at the same time, the detection angle

of both must be horizontally adjusted. Set the

sensitivity setting to H in this case (see

Adjustment of the sensitivity).
