Option C
Mount the SPS on the top of the fume hood.
STEP 1
Ensure the cable is free from obstruction along the entire length of sash movement.
STEP 2
The sensor cable may be attached directly to the counterweight. This configuration may be
desired when the sash connects to the counterweight with a belt and pulley system.
STEP 3
Run the sensor cable back to the CAVA mounted on the front of the fume hood and connect it
to a Universal Input (see Electrical Installation
Option D
Mount the SPS on the inside wall of the fume hood. This is the least preferable mounting
option, as the sensor is directly in the exhaust air stream.
STEP 1
Ensure that the sensor and cable do not interfere with the mechanical operation of the fume
hood sash.
STEP 2
Ensure the sensor is as close to the sash as possible so that the cable is completely parallel to
the sash in all positions.
STEP 3
Raise the sash to the fully open position (not just the working height). Screw the metal ring into
the sash. Ensure that the sensor is mounted higher than the fully open position of the sash.
STEP 4
Once mounted, raise and lower the sash several times to ensure that the cable is clear of all
obstructions and moves freely with the sash.
STEP 5
Run the sensor cable back to the CAVA mounted on the front of the fume hood and connect it
to a Universal Input (see Electrical Installation
