Installation
!WARNING
Install the sensor system so that it is not affected by reflective surfaces. Fail-
ure to do so may hinder detection, resulting in serious injury.
10-1 Reflective Surface Interference
A reflective surface adjacent to the detection zone can deflect the optical
beam and may cause an obstruction in the zone not to be detected. The
reflective surface may be part of the machine, mechanical guard or work-
piece. Therefore, a minimum distance (d) must exist between the reflective
object and the center line of the detection zone. The Test procedure (Appen-
dix B) must be used to test for this condition.
In this picture, the interruption is clearly detected. The reflective object is out-
side of the beam angle
The following pictures show the scenario if the reflective surface is too close
to the beam angle.
In this case, the interruption is not detected because the reflective object is
inside the beam angle.
