5 Function
The protected area (P) is generated between the transmitter and the receiver and
is defined by the protected area height (H) and the protected area width (range)
(I).
The protected area height is the height protected by the safety light grid. It
depends on the design (→ 12 Technical data).
The protected area width (range) is the maximum distance between transmitter
and receiver (→ 12 Technical data).
If the protected area is clear, the two outputs (OSSDs) of the receiver are active.
When one of the light beams is interrupted, the light grid switches off the outputs.
