3.3.4 Emitter/Receiver Orientation
The emitter and receiver must be mounted vertically, and
parallel to each other. Otherwise dangerous voids in the light
grid could allow objects or personnel to pass undetected through
the grid (see Figure 3-8). Be certain the light grid covers all
access to the guarded area not otherwise protected by hard
guarding or other supplemental guarding.
