Align the sensor to roadway
1
Pan and tilt the mount so that the mount head points to
the target location in the center of the lanes of interest.
2
Attach the sensor to the mount making sure the sensor
can still roll with respect to the mount head.
3
Attach the Advance viewfinder by centering the arched
notch over the top-middle of the sensor and inserting it
into position.
4
From behind the sensor, tilt the sensor until the target
location lines up between the target crossbars.
5
Pan the sensor until the target location is centered be-
tween the notches in the target crossbar. When you have
the correct view angle, the bottom center notch should
also line up with the bottom part of the long, narrow
alignment bar.
6
Roll the sensor until the long, narrow bar is parallel with the center of the lanes of interest on the road-
way. Vehicle paths should be parallel to the long, narrow bar.
7
To verify your alignment within the upstream detection area, move your head down so you can see the
top crossbar and the archway, then make sure the archways overlap and the top tabs line up with the top
crossbar. Vehicle paths should still be parallel to the long, narrow bar.
8
Tighten down the pan and tilt bolts, then tighten down the four bolts on the backplate.
3
Attach the sensor and mount bracket to the pole
1
Insert the stainless steel straps through the slots in the mount bracket, then position the mount on the
pole so the mount head points toward the lanes of interest at a 45° angle. Tighten the strap screws.
2
Align the bolts on the sensor’s backplate with the holes in the mount bracket. The eight-pin connector
receptacle on the bottom of the sensor should be pointing towards the ground.
3
Place the lock washers onto the bolts after the bolts are in the mount bracket holes. Thread on the nuts
and tighten.
5
Attach the 6-conductor cable and ground the sensor
1
Squeeze 25% of the silicon dielectric compound into the connector at the base of the sensor; wipe off excess.
2
Insert the cable into the connector and twist clockwise until you
hear it click into place.
3
To avoid undue movement from wind, strap the cable to the pole
or run it through a conduit with enough slack to reduce strain.
4
Connect a grounding wire to the grounding lug on the bottom of
the sensor.
5
Connect the other end of the grounding wire to the earth ground
for the pole that the sensor is mounted on.
6
Route the service end of the cable back to the main traffic cabinet.
