Wiring (Vertical)
Outside sash UniTrak mount:
1. Plug the sensor connector into the connector on
the end of the UniTrak strip.
2. Route the sensor and attached wiring so that
when the vertical sash is moved up and down
the wires will not interfere with the sash
movement.
Inside sash UniTrak mount:
1. Remove the access panel on the inside wall of
the fume hood.
2. Drill a 3/8-inch hole through the inside wall of the
fume hood.

3. Route the sensor wires between the fume hood
and the bottom of the airfoil, and to the
controller.
4. At the FHC, wire the sensors as per the
application. The black wire is common and the
red wire is the signal. The white wire is not used
for vertical (single actuator car) sensors. See
Figure 26. Secure the wires with the wire tie
mounts and nylon wire ties. Trim the wire ties
with the wire cutters.
5. If there are multiple sashes, use the wire marker
labels to number the end of the sensor wires.
See Figure 27 for proper sash numbering.
Figure 27. Sash Wire Numbering.
6. Bundle multiple wires together every 12 inches
(30 cm).
3. Insert the white plastic bushing in the 3/8-inch
hole.
4. Route the sensor wires through the hole, and fill
the bushing with the silicon in the white tube.
See Figure 28.
