Figure 41: Maximum allowable displacement for a range of fume hood widths
1.
The area protected by the light beams should cover the open area under the sash, typically
500 mm (20") from its base.
The light curtain transmitter and receiver can be positioned above the bottom of the sash in
the fume hood if they are free from obstructions.
Where possible, make sure the light path is aligned flush to the bottom of the sash base.
Note: There is a 123 mm (4.84") gap from the top of the light curtain transmitter to the first
LED down and a 22 mm (0.87") gap from the bottom of the transmitter to the first
LED up.
