Distance from reflective surfaces
If there are reflective surfaces near the beams emitted from the safety light curtain (whether
from above, below, or from the side), passive reflections can cause an object within the pro-
tected field to remain undetected (see diagrams).
As a result, the safety light grid
must be installed at a minimum distance from reflective sur-
faces.
