Intersection Equipment Installation Instructions
Determine the appropriate length of wire required
to connect the auxiliary harness to the wiring
points in the load bay of the traffic control
cabinet. See Table 5-4 to select the proper phase
green wires from the wiring harness.
Route the wires through the traffic control cabinet
to the load bay.
Remove cable ties from the wiring harness as
necessary. Cut the phase green wires to the
proper length, strip 1/4 inch of insulation from the
ends of the wires being used, and install spade
lugs on them. Insert each green sense wire, one
at a time, into the correct terminal in the load bay
and tighten the screw.
Locate and identify the AC neutral connection in
the traffic control cabinet.
Route the white wire from the auxiliary harness
through the traffic control cabinet to the AC
neutral connection. Strip 1/4 inch of insulation
from the end of the white wire, install a spade lug
on it, and connect the wire to the AC neutral
connection.
Verify that your wiring is correct, and the
connections are tight.
Verify that green sense wires are connected
correctly.
To do this, open ITS Explorer and select
Intersection Configuration, then Real-Time
Activity, then View Vehicles and Intersections
Heard. When the Real-Time Status window
opens, select the Tracking Status tab and compare
the Current Greens field to the active greens
indicated on the controller or conflict
monitor/MMU.
Reconnect any green sense wires that may be
incorrect.
