for vertical (single actuator car) sensors. See
Figure 26.
8. Secure the wires with the wire tie mounts and
nylon wire ties. Trim the wire ties with the wire
cutters.
9. 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.
10. Bundle multiple wires together every 12 inches
(30 cm).
The installation is now complete.
Wiring (Horizontal)
1. Use the wire marker labels to number the
sensor connector wire ends according to
Figure 29.
Two Horizontal Sash Panels.
Four Horizontal Sash Panels.
Figure 29. Sash Wire Numbering.
NOTE: For combination sash fume hoods,
route the wiring so that when the
vertical sash is moved up and down
the cables will not interfere with the
sash movement. Use the wire ties
and wire tie mounts to hold the wires.
Figure 30. Sash Sensor on Combination Fume Hood.
Figure 31. Wire terminations for sash 2 and 4
(for Figure 30)
2. For outside-mounted UniTrak sensors
(horizontal fume hoods), drill a 3/8-inch (9.5 mm)
hole through the front airfoil or the fume hood
frame approximately 2 inches (51 mm) from the
end of the UniTrak. Remove metal filings with
the portable vacuum cleaner.
CAUTION:
Before drilling, ensure that metal filings will
not fall on laboratory equipment such as
beakers and heating elements. Remove
metal filings with the portable vacuum
cleaner after drilling.
3. Snap a plastic bushing into each hole and route
the sensor connectors on the ends of the
UniTrak through the hole (Figure 32). For inside-
mounted UniTrak sensors, route the wiring
through existing openings.
Figure 32. Bushing Placement for Outside Mounted
UniTrak Wiring.
4. Plug the connectors in to the UniTrak sensor.
5. Route the wires to the controller. Use wire ties
and wire tie mounts to hold wires in place.
Bundle multiple wires together every 12 inches
(30 cm).
