Typical Installation
PROBE INSTALLATION IN A ROADWAY
Please read INSTALLATION GUIDLINES prior to installation.
DO NOT INSTALL IN HOT ASPHALT
When the detector is set to maximum sensitivity (full clock-wise on the sensitivity adjustment)
detection distance is approximately 12ft at a speed of 5mph. At higher speeds, 10-15mph, detection
distance can exceed 12ft.
1.
The probe should be positioned in the center of the roadway, perpendicular to the direction of
traffic. Place the probe in plastic conduit to prevent damage to probe and cable. Probe should
be located at approximately 2” depth in concrete or asphalt. The probe may be located prior to
paving, or a cut may be made in the pavement for installation. No rebar should be above the
probe.
2.
Once the probe is installed, connect the probe to the CS101 and power, output contact and
earth ground to the intended equipment. Both the probe shield and PIN 6 of the CS101 must
be connected to the earth ground (reference EARTH GROUND CONNECTION in the
INSTALLATION GUIDELINES section).
3.
Apply power and allow 5 minutes warm-up for system stabilization.
4.
Set sensitivity to minimum and output delay to maximum (approximately 6 seconds).
5.
Drive the vehicle over the probe at a typical speed and each side of the roadway.
6.
Repeat this step while gradually increase the sensitivity until the system detects the vehicle. A
higher sensitivity setting than required to detect the vehicle makes the system more vulnerable
to triggering from unintended sources such as movement of other objects in the sensitive area
or other electrical disturbances.
