Ground the sensor
5
Attach the SmartSensor 6-conductor cable
1
Tear the tab off the silicon dielectric compound and squeeze about 25% of it into the connector at the
base of the sensor. Wipe off any excess compound.
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, but leave
a small amount of slack at the top of the cable to reduce strain.
The SmartSensor Rail provides its own surge protection, so there is
no need for a pole-mount box on the sensor side of the cable. Instead,
the cable should run straight to the main traffic cabinet; landing the
cable in the cabinet will be covered later in this document.
It is necessary, however, to ground the sensor:
1
Connect a grounding wire to the grounding lug on the bottom of
the sensor.
2
Connect the other end of the grounding wire to the earth ground for the pole that the sensor is mount-
ed on. Do not attempt to run the grounding wire back to the main traffic cabinet.
7
Attach the sensor cable junction box
The Sensor Cable Junction Box provides connection between the sensor’s pigtail cable and the homerun
cable to the cabinet. Using the junction box means that you will not need to pull the cable all the way from
the sensor to the cabinet.
Note.
The sensor cable junction box is optional and may not be needed with every sensor installation.
Follow the steps below to install the junction box to the SmartSensor Rail detection system:
1
Connect the cable coming from the sensor to one side of
the junction box by pushing the cable through one of the
cable grips.
2
Once the cable is through the cable grip, connect the
cable wires to the terminal blocks inside the junction
box.
3
Push the cable from the cabinet through the other cable
grip.
4
Connect the same colored wires to the terminal block
directly accross from the sensor cable wires.
Note.
Make sure that the same colored wires are directly across from each other.
