Use the following steps to correctly align SmartSensor Matrix.
1. Adjust the side-to-side angle so that the front-edge of the beam provides a
view downstream of the stop bar.
2. Tilt the sensor down so it is aimed at the center of the lanes of interest.
3. If necessary rotate the sensor back plate so that the bottom-edge of the
sensor is parallel with the roadway. This is necessary where the intersection
approach has a significant grade.
Applying Silicon Dielectric Compound
Use the following steps to correctly apply the silicon dielectric compound: Tear the
tab off of the tube of Silicon Dielectric Compound.
1. Squeeze about 25% of the silicon onto the pins of the receptacle-side of the
connector at the base of the SmartSensor Matrix (see Figure 1.5).
2. Be sure to wipe off any excess compound.

Connecting the SmartSensor Cable
The sensor connector is keyed to ensure proper connection (see Figure 1.6); simply
twist the plug end of the connector clockwise until you hear it click into place.
Use the following steps to connect the SmartSensor Matrix Cable:
1. Insert and turn the connector to attach it. Match up the key for a quick
connection.
2. Connect one end of a protective earth ground wire to the ground lug
terminal. A 12 AWG stranded wire is recommended for ground connections.
3. Connect the other end of a protective earth ground wire to an earth ground
connection point.
To avoid undue movement from the wind, strap the cable to the pole or run it
through a conduit, but leave a small amount of slack at the top of the cable to
reduce cable strain.
