e Wavetronix SmartSensor HD trac sensor utilizes the latest technology to collect and deliver trac statistics. e SmartSensor HD collects information through the use of a
24.125 GHz (K band) operating radio frequency and is capable of measuring trac vol­ume and classication, average speed, individual vehicle speed, lane occupancy and pres­ence. e SmartSensor HD uses what is classied as frequency modulated continuous wave (FMCW) radar; it detects and reports trac conditions simultaneously over as many as 22 lanes of trac.
Once SmartSensor HD is installed, the conguration process is quick and easy. Aer in­stallation, this unit will require little or no on-site maintenance and can be remotely re­congured for optimal performance. is user guide outlines the step-by-step process of installing and conguring the SmartSensor HD. Any questions about the information in this guide should be directed to Wavetronix or your distributor.

Selecting a Mounting Location
Consider the following guidelines when selecting a mounting location:
Lane Coverage – Sensor mounting locations should be selected so that all monitored
lanes are within 6 to 250 . (1.8 to 76.2 m) of the sensor and run parallel with each other. Multiple sensors should be considered if more than 10 lanes need to be simulta­neously monitored. If lanes do not need to be simultaneously monitored, up to 22 lanes can be congured for collection by a single sensor.
Parallel Lanes – When the sensor is used to collect both mainline and ramp data, the
pole position should be selected so that the on and o ramp lanes run parallel with the mainline. If lanes are not parallel, installation of multiple SmartSensor HD units should be considered.
Sensors on the Same Pole – When multiple sensors are mounted on the same pole,
they will not be subject to interference if they are congured to operate using dierent RF channels and are separated vertically by a few feet. e higher sensor would typi­cally be used for the lanes farther from the pole in order to minimize occlusion.
Sensors on Opposing Poles – SmartSensor HD units facing each other on opposing
poles should operate on dierent RF channels and be separated by a 70-. (21.3-m) lateral oset, if possible.
Line of Sight – e SmartSensor HD is designed to work accurately in the presence of
barriers, but in general if there is an alternate mounting location that would avoid any type of structural occlusion, this is preferred. Avoid occlusion by trees, signs, and other roadside structures.
Neighboring Structures and Parallel Walls – To eliminate the risk of performance
degradation, the sensor locations should have a 30-. (9.1-m) lateral separation from overhead signs, overpasses, tunnels, parallel walls, and parallel parked vehicles in order to avoid multiple reection paths from a single vehicle. is separation removes the objects from the antenna pattern of the sensor. In practice the sensor has been mounted much closer to reecting objects with minimal impact in sensor performance. For ex-
INTRODUCTION  SMARTSENSOR HD USER GUIDE 7
ample, sensors mounted on gantries have successfully met customer requirements when using a 3-foot extension arm to laterally separate the sensor from the structure. Please talk with a Wavetronix Technical Support representative about your specic situation.
Mounting Height – e mounting height should be based upon the oset from the
lanes of interest. For each oset, the minimum, maximum, and best heights are shown in Table 1.1, found in Chapter 1. In general, the range of recommended heights is be­tween 9 and 50 . (2.7 to 15.2 m).
Mounting Oset – e minimum recommended oset (distance from the sensor to
the edge of the rst lane of interest) is 6 . (1.8 m).
Arterial Locations – Sensor sites on arterials or other roadway segments with regulat-
ed stop lines should be selected at midblock positions to increase accuracy by avoiding positions at which vehicles are oen stopped in front of the sensor.
Freeway Locations – e SmartSensor HD is oen used at permanent ATR (auto-
matic trac recorder) stations. e number of stations along a single roadway and the distance between stations should be selected to achieve adequate levels of statistical condence. Permanent ATR stations, which are selected to cover interstate, principal arterial, and other national and state highways, are used to establish seasonal adjust­ment factors for count data from temporary collection sites (see Figure I.1).

Cable Lengths – Ensure that you have sucient homerun and sensor cabling. Cables
can be as long as 600 . (182.9 m) if they’re using 24 VDC operation and RS-485 com­munications; for longer connections, alternate wired and wireless options should be considered.
Signaling Delay – Aer a vehicle passes in front of the sensor there will be a slight
delay before the data for that vehicle is sent from the sensor. In a time-sensitive ap­plication—for instance, to supply a dynamic message sign with per vehicle warning messages—it will be necessary to ensure the sensor is suciently far upstream from the sign that the system has time to collect the data, process it, and send it to the sign by the time the vehicles reach the problem area. For specics about signaling delay, see Appendix E.

14 CHAPTER 1 INSTALLING THE SMARTSENSOR HD
Attaching the Mount Bracket to the Pole
Before attaching the mount bracket to the pole, rst make sure that your cables are long enough to reach the sensor and to stretch across the distance from the sensor to the cabinet.
Follow the steps below to correctly attach the mount to the pole (see Figure 1.2):
1 Insert the stainless steel straps through the slots in the mount bracket. 2 Position the mount bracket on the pole so that the head of the mount is pointing to-
wards the middle of the lanes of interest.
3 Tighten the strap screws.
Note
The sensor will need to be adjusted later, to fine-tune the alignment, so be sure to keep the straps adjustable.
Figure 1.2 – Attaching the Mount Bracket to the Pole
Attaching the Sensor to the Mount Bracket
Use the following steps to securely fasten the sensor to the mount bracket:
1 Align the bolts on the sensor’s backplate with the holes in the mount bracket. e con-
nector at the bottom of the unit should be pointing towards the ground.
2 Place the lock washers onto the bolts aer the bolts are in the mount bracket holes. 3 read on the nuts and tighten (see Figure 1.3).
CHAPTER 1  INSTALLING THE SMARTSENSOR HD 15
Note
Do not over-tighten the fasteners.
Figure 1.3 – Attaching the Sensor to the Mount Bracket
Aligning the Sensor to the Roadway
Use the following steps to correctly mount and align the SmartSensor HD:
1 Tilt the sensor down so that the front is aimed at the center of the detection area (see
Figure 1.4).
Figure 1.4 – Up-and-down Positioning
2 Adjust the side-to-side angle so that it is as close to perpendicular to the ow of trac
as possible (see Figure 1.5).
16 CHAPTER 1  INSTALLING THE SMARTSENSOR HD
Note
The side-to-side alignment will eventually be fine-tuned for better accuracy using SmartSensor Manager HD (SSMHD). That step will be addressed in Chapter 6, after SSMHD has been installed.
Side-to-side alignment should
be perpendicular
Figure 1.5 – Side-to-side Positioning
Applying Silicon Dielectric Compound
Use the following steps to correctly apply the silicon dielectric compound:
1 Tear the tab o of the tube of silicon dielectric compound. 2 Squeeze about 25% of the silicon into the connector at the base of the SmartSensor HD
(see Figure 1.6). Be sure to wipe o any excess compound.
Figure 1.6 – Applying Silicon Dielectric Compound
CHAPTER 1  INSTALLING THE SMARTSENSOR HD 17
Connecting the Cable
e sensor connector is keyed to ensure proper connection; once you have plugged the cable connector into the sensor connector, simply twist the cable connector clockwise until you hear it click into place. 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 (see Figure 1.7).
Note
If you run the cable through the pole, do not drill through the sensor mount, as the sensor and sensor mount may need to be adjusted in the future.
Figure 1.7 – Sensor Connector
e service end of the cable has a +DC and GND for a power supply of 12 to 24 VDC. Two communication ports (either RS-232 or RS-485) are available to connect the SmartSensor HD to a modem or other communication device. Typically, one RS-485 and one RS-232 port are available.

Once the sensor is installed, it will need to be wired for power and surge protection. Wa­vetronix Click products allow you to quickly and easily include power and surge protection in your sensor application. Please refer to the Click quick-reference guides for more com­prehensive product instructions.
ere are several ways your sensor might be set up:
 A two-part installation, with components in two areas: rst, a pole by the road holds
your sensor plus a pole-mount box with a surge protector inside. Second, a main trac cabinet holds power and communications devices. e cabinet and pole are connected via a homerun cable that runs underground.
Note
This chapter assumes the box and cabinet are connected by an underground cable run, but in certain circumstances they might not be.
20 CHAPTER 2  CONNECTING POWER AND SURGE
 A single-part installation, with all components on the same pole. is pole holds your
sensor. Power and communications devices (most likely wireless) are in a pole-mount box or there is a trac cabinet at the base of the pole; either way there is no under­ground cable run. Power comes from the pole itself or from a battery and/or solar panels at the pole.
How you set up the devices in this chapter will vary depending on which of these installa­tions you are using.
Connecting Lightning Surge Protection
e sensor should be connected to at least one surge protection device. e Click 200 and equivalent devices are designed to prevent electrical surges along cables from damaging the sensor and/or the cabinet. It is also a convenient spot to terminate the cable coming from your sensor, as it has terminals for all the wires.
Note
If you choose not to use surge protection in your installation, please contact Wa­vetronix Technical Services for assistance.
If you are using the one-part installation option—no underground cable run—put a Click 200 in the pole-mount box/trac cabinet (whichever is being employed) as a termination point for the cable from the sensor, and as a way to protect the box/cabinet. When there is no un­derground cable run, it is safest practice, as well as Wavetronix standard procedure, to connect the cable from the sensor in the UNPROTECTED side of the Click 200.
1 Install a Click 200 in the pole-mount cabinet/trac cabinet by snapping it onto the
DIN rail. Your power and communications devices will most likely also be on this DIN rail; make sure the Click 200 is connected to them via wires or the shared communica­tion bus (connecting power will be covered later in this chapter; for how to connect to communications devices, see the Click 100–400 Series User Guide).
2 Wire the cable from the sensor to the UNPROTECTED side of the Click 200.

Smart
Sensor
Figure 2.1 – Using a Single Click 200
Note
The dierent cables available and how to wire them into the Click 200 will be covered later in this section.
If you are using the two-part installation option, you’ll have an underground cable run as part of your installation, connecting the power and comms devices in the main trac cabi­net to the pole-mount box and sensor. When there is an underground cable run, it is safest practice, as well as Wavetronix standard procedure, to use two Click 200s, one on each end of the cable: one in the main trac cabinet and the other in the pole-mount cabinet. Both ends of the cable should be connected to the UNPROTECTED side of their Click 200s. is is important because the underground cable run will be susceptible to surges caused by lightning striking the ground near it.
If this run is shorter than 600 . (182.9 m), you can use a Wavetronix cable; see Appendix D for more on cable lengths.
1 Install one Click 200 device in a pole-mount cabinet on the same pole as the sensor
being protected. Install it by snapping it onto the DIN rail.
2 Connect the cable from the sensor to the PROTECTED side of this Click 200. is
cable should be kept as short as possible.
3 Install another Click 200 in the main trac cabinet. You will likely have power and com-
munications devices in this cabinet; make sure the Click 200 is connected to them via wires or the shared communication bus (connecting power will be covered later in this chapter; for how to connect to communication devices, see the Click 100–400 Series User Guide).
4 Connect the pole-mount box and the main trac cabinet by running a cable from the
UNPROTECTED side of the Click 200 in the pole-mount box to the UNPROTECTED side of the Click 200 in the main trac cabinet.

Wiring the Click 200
ere are two cables that may be used with your sensor, the 8-conductor cable and the 9-conductor cable. Which one you use is based largely on the connector on your SmartSen­sor HD—that is, the connector where the cable will be plugged into the sensor.
ere are two dierent connectors that may be found on a SmartSensor HD:
 e 10-pin connector is used with the SmartSensor HD. It currently only comes in-
stalled on the 8-conductor cable.
 e 26-pin connector is used with SmartSensor HD Legacy and retrotted HDs. It can
be installed on the 8-conductor cable or the old 9-conductor cable.
Note
There may be compatibility issues if you use a 8-conductor/26-pin connector cable with a SmartSensor HD that was manufactured in or before 2008. Contact Wavetro­nix Technical Services for details and assistance.
e wiring for these two cables is almost identical; the dierences are pointed out on the following page.
Note
If you have an underground cable run that stretches more than 600 ft (182.9 m), you will likely need to use a dierent cable; in that case the colors won't match the figure below.
CHAPTER 2  CONNECTING POWER AND SURGE 23
e Click 200 contains three terminal connectors on both the top and the bottom of the module (see Figure 2.3). e terminal connectors are removable and are red-keyed, al­lowing each connector to plug into only one specic jack. is both simplies the wiring process and reduces the possibility of wiring errors.

Wiring to Earth Ground
All Click 200 devices should be mounted on a DIN rail that is connected to earth ground either through an earth-grounded chassis or a 16 AWG or larger grounding wire attached to a 7-. (2.1-m) grounding rod. Follow the steps below to correctly wire to earth ground:

1 Connect the grounding wire from either the DIN rail or a GND screw terminal on the UN-
PROTECTED side of the Click 200 to the lug bolt on the inside of the pole-mount cabinet.
2 Connect another grounding wire from the exterior lug bolt to earth ground (see Figure 2.4).

Installing the Power Plant
Provide power to your installation using the Click power plant. is set of modules includes the following:
 Click 201/202 AC to DC converter  Click 210 circuit breaker and switch  Click 230 AC surge module
A Click 201 provides 1 A of power and is capable of powering a single sensor, while a Click 202 provides 2 A and can power two sensors. (ere is also a Click 204 which provides 4 A of power, but that will usually not be necessary in an installation such as the one outlined below.) e Click 230 helps limit current surges on the power lines; the Click 210 interrupts power during overload conditions and provides a convenient way to turn power on and o.
e power plant will either be in a pole-mount box or in a main trac cabinet. If it’s in a trac cabinet, the power will be sent to the pole via an underground cable run. How to in­stall the power plant and then wire to a Click 200 will be covered in the rest of this section.
It should be noted that if you have ordered a Wavetronix preassembled cabinet, all of this wiring and installation will already be done.

Note
An authorized electrical technician should perform installation and operation of this unit. Persons other than authorized and approved electrical technicians should NOT attempt to connect this unit to a power supply and/or trac control cabinet, as there is a serious risk of electrical shock through unsafe handling of the power source. Ex­treme caution should be used when connecting this unit to an active power supply.
Wiring in AC
e rst step is to get AC power into the enclosure. (Sometimes the power source is actually DC; to see Wavetronix’s selection of DC power modules, see the Click 100–400 Series User Guide.) If you’re using a main trac cabinet, wire from its power source; if you’re using a pole-mount box, the power lines or cable can be brought in through the conduit on the bottom-le.
Note
Make sure power to AC mains is disconnected while wiring AC input.
Wiring the Click 210
e rst device in the power plant, as seen in Figure 2.5, is the Click 210. is is a compact circuit breaker DIN rail device designed to interrupt an electric current under overload conditions. e breaker is trip-free and can be easily reset aer a current interruption by pushing the reset button.

To add a Click 210 circuit breaker and switch (see the le side of Figure 2.5):
1 Mount the Click 210 onto the DIN rail. 2 Connect the line conductor (usually black) from the AC terminal block or cord in to
either side of the module.
3 Wire out of the other side.
Note
For ease in troubleshooting, it is recommended that you follow the wire color scheme outlined in this chapter.
Wiring the Click 230
e next device in the power plant is the Click 230, which is the AC surge protector (see Figure 2.5). To install:
1 Mount the Click 230 onto the DIN rail next to the Click 210. 2 Connect the line conductor (black) from the Click 210 to terminal 5 on the IN side of
the Click 230.
