Introduction In the Introduction SmartSensor Package Selecting a Mounting Location The Wavetronix SmartSensor 105 utilizes patented Digital Wave Radar™ technology to detect lane occupancy, traffic volume and average speed in up to eight lanes of traffic simultaneously. Classified as Frequency Modulated Continuous Wave (FMCW) radar, SmartSensor collects data using a 10.525 GHz (X-band) operating radio frequency. The installation and configuration process is quick and easy.
INTRODUCTION o SMARTSENSOR USER GUIDE SmartSensor 105 Package A typical sensor package contains the following items: 10.525 GHz SmartSensor Radar Traffic Sensor SmartSensor mounting kit SmartSensor cable SmartSensor Manager software SmartSensor User Guide Caution Check the packing slip for actual contents. If any of these items are missing, note the serial number located on the back of the sensor and contact your distributor.
INTRODUCTION o SMARTSENSOR USER GUIDE the pole in order to minimize occlusion. Sensors on Opposing Poles – SmartSensor units facing each other on opposing poles should operate on different RF channels and be separated by a 40-ft. (12.2-m) lateral offset, if possible. Line of Sight – The SmartSensor 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.
INTRODUCTION o SMARTSENSOR USER GUIDE confidence. 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 sufficient homerun and sensor cabling. Cable runs as long as 600 ft. (182.9 m) using 24 VDC operation and RS-485 communications.

16 CHAPTER 1 o INSTALLING THE SMARTSENSOR 105 Figure 1.2 – Attaching the Mount Bracket to the Pole Note Depending on the site and type of traffic, the sensor may tend to overor undercount. If the sensor is overcounting, reduce the height of the sensor by three ft. (0.9 m) and reconfigure the sensor. If the sensor is undercounting, increase the height of the sensor by three ft. (0.9 m) and reconfigure. Normally, reducing the height of the sensor improves performance.
CHAPTER 1 o INSTALLING THE SMARTSENSOR 105 Figure 1.3 – Attaching the Sensor to the Mounting Bracket Aligning the Sensor to the Roadway Follow the steps below to correctly align the SmartSensor (see Figure 1.4): Figure 1.4 – Aiming the SmartSensor 1 2 3 Aim the front of the sensor at the center of the detection area. You may also refer to Figure 1.1 as an illustration of where to aim the sensor. Adjust the side-to-side angle to within approximately ±2° of perpendicular to the flow of traffic.
18 CHAPTER 1 o INSTALLING THE SMARTSENSOR 105 Applying Silicon Dielectric Compound Use the following steps to correctly apply the silicon dielectric compound: 1 2 Tear the tab off the tube of silicon dielectric compound. Squeeze about 25% of the silicon into the connector at the base of the SmartSensor as shown in Figure 1.5. Be sure to wipe off any excess compound. Figure 1.
Connecting Power and Surge Protection 2 In this Chapter Connecting Lightning Surge Protection Connecting AC Power Conversion Connecting DC Power Wiring Communication Once the sensor is installed, it will need to be wired for power and surge protection. This chapter will explain how to connect lightning surge protection, AC power conversion, DC power and basic communication.
20 CHAPTER 2 o CONNECTING POWER AND SURGE PROTECTION Smart Sensor Underground Cable Figure 2.1 – Protecting the Sensor Note If you choose not to use surge protection in your installation, please contact Wavetronix Technical Services for assistance. In many installations, the pole-mount cabinet is also connected to a main traffic cabinet via an underground homerun cable. To protect the traffic cabinet, a second surge device is strongly recommended.
CHAPTER 2 o CONNECTING POWER AND SURGE PROTECTION Main Traffic Cabinet Smart Sensor Pole Mount Traffic Cabinet Both ends of the homerun cable connect to the UNPROTECTED side of the surge modules. 120 VAC Figure 2.2 – Typical Cable Run The Click! 200 contains three terminal connectors on both the top and the bottom of the module (see Figure 2.3). The terminal connectors are removable and are red-keyed, allowing the connector to plug into only one specific jack.
22 CHAPTER 2 o CONNECTING POWER AND SURGE PROTECTION Figure 2.3 – Surge Protected Terminal Connections (Top) Figure 2.3 above shows the PROTECTED side of the Click! 200. The UNPROTECTED side of the Click! 200 contains the same screw terminal connections, but are reversed from left to right. Note See Appendix B for a description of how to wire the Click! 200 using the old SmartSensor cable as well as for a cable connector pin out diagram.
CHAPTER 2 o CONNECTING POWER AND SURGE PROTECTION Figure 2.4 – Earth Ground Connections Connecting AC Power Conversion Since the sensor operates on 10-30 VDC, it is necessary to provide AC power conversion when reliable DC power is not already available. Wavetronix recommends using the following three Click! components: Click! 201/202 AC to DC converter Click! 230 AC surge module Click! 210 circuit breaker and switch Warning Make sure power to AC mains is disconnected while wiring the AC input.
24 CHAPTER 2 o CONNECTING POWER AND SURGE PROTECTION Caution 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 traffic 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.
CHAPTER 2 o CONNECTING POWER AND SURGE PROTECTION 4 5 6 Connect the ground wire from the AC terminal block or cord to the terminal marked 3 on the Click! 230. Connect the outgoing and protected line wire to the terminal marked 2 on the Click! 230. Connect the outgoing and protected neutral wire to the terminal marked 6 on the Click! 230. The terminal blocks 3 and 4 are directly bonded via the metal mounting foot of the base element to the DIN rail.
26 CHAPTER 2 o CONNECTING POWER AND SURGE PROTECTION 2 Connect a -DC conductor (usually a black wire) to either of the - screw terminals on the bottom of the Click! 201/202. Figure 2.7 – Wiring DC Power Out of the Click! 201/202 Note Do not use the screw terminal marked DCOK; it provides only 20 mA and should be used only for monitoring the power supply.
CHAPTER 2 o CONNECTING POWER AND SURGE PROTECTION If the DC power comes from a Click! 201/202 in the pole-mount cabinet that is surge protected using a Click! 230, you can also connect power to the T-bus using a 5-position screw terminal. To wire DC power directly into a 5-position screw terminal (see Figure 2.8): 1 2 Connect +DC (24 VDC) to the top screw terminal. Connect –DC to the second screw terminal. +24V DC -DC +485 -485 GND (red wire) (black wire) Green Gray Figure 2.
28 CHAPTER 2 o CONNECTING POWER AND SURGE PROTECTION Figure 2.9 – Wiring DC Power into the Click! 200 Wiring Communication After wiring the sensor cable into the PROTECTED side of the Click! 200 in the pole mount cabinet, two isolated serial connections are available. The sensor’s native RS-232 port is available via the DB-9 connector on the faceplate.
CHAPTER 2 o CONNECTING POWER AND SURGE PROTECTION should not be connected until each card has been independently programmed (see Figure 2.10). Figure 2.10 – Connecting Contact Closure Modules Note Wait to connect contact closure communications until after the sensor is programmed using the configuration software. See Chapter 9 for more information on contact closure communications.
