Distance From Reflective Surfaces - Pilz PSEN op4H-SL Series Operating Manual

PSEN op4H-SL Series
The transmitter of one safety light grid must not interfere with the receiver of another
}
safety light grid.
The transmitters and receivers of two different safety light grids must not be synchron-
}
ised.
Avoid strong electromagnetic interference when operating the safety light grid.
}
When operating the safety light grid, avoid the development of smoke, mist, or dust that
}
would reduce the grid's operating range.

Distance from reflective surfaces

If there are reflective surfaces near the beams emitted from the safety light grid (whether
from above, below, or from the side), passive reflections can cause an object within the pro-
tected field to remain undetected (see diagrams).
This means that there must be a certain minimum distance between the safety light grid
and reflective surfaces.
