6INTRODUCTION o SMARTSENSOR USER GUIDE SmartSensor 105 PackageA typical sensor package contains the following items:10.525 GHz SmartSensor Radar Trac SensorSmartSensor mounting kitSmartSensor cableSmartSensor Manager softwareSmartSensor User GuideCautionCheck 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. Additional products may be purchased through your distributor. The following optional items are not included unless specically ordered (check packing list for actual inventory):Click! 172/174™ contact closure adapterClick! 200™ surge protectorClick! 201/202™ AC to DC converterClick! 210™ circuit breaker and switchClick! 230™ AC surge moduleSelecting a Mounting LocationConsider the following guidelines when selecting a mounting location:Lane Coverage – Sensor mounting locations should be selected so that all monitored lanes are within 10 to 200 ft. (3 to 61 m) and run parallel with each other. If more than eight lanes need to be simultaneously monitored, consider using multiple sensors or the SmartSensor HD, which can monitor up to 10 lanes simultaneously.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 units should be considered to achieve the sensor’s ±2° side-to-side angle requirement. 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 operating using dierent RF channels and are separated vertically by a few feet. The higher sensor would typically be used for the lanes further from

7INTRODUCTION o SMARTSENSOR USER GUIDEthe pole in order to minimize occlusion.Sensors on Opposing Poles – SmartSensor units facing each other on opposing poles should operate on dierent RF channels and be separated by a 40-ft. (12.2-m) lateral oset, 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. Avoid occlusion by trees, signs, and other roadside structures.Neighboring Structures and Parallel Walls – It is also preferred that sensor locations have a 30-ft. (9.1-m) lateral separation from overhead sign bridges, overpasses, tunnels, parallel walls and parallel-parked vehicles in order to avoid multiple reection paths from a single vehicle.Mounting Height – The mounting height should be based upon the oset from the lanes of interest. For each oset, the minimum, maximum and recommended range of heights is shown in Table 1.1, found in chapter 1. In general, the range of recommended heights is between 9 and 50 ft. (2.7 to 15.2 m).Mounting Oset – The minimum recommended oset from the edge of the rst lane of interest is 10 ft. (3 m).Arterial Locations – Sensor sites on arterials or other roadway segments with regulated stop lines should be selected at mid-block positions to increase accuracy by increasing line of sight to stop-and-go vehicles. Portable (left) and Permanent (right) Sensor Stations Figure I.1 – Freeway Locations – SmartSensor is often used at permanent ATR stations. The number of stations along a single roadway and the distance between stations should be selected to achieve adequate levels of statistical

8INTRODUCTION o SMARTSENSOR USER GUIDE 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. Cable runs as long as 600 ft. (182.9 m) using 24 VDC operation and RS-485 communications. For longer connections, alternate wired and wireless options should be considered.

16 CHAPTER 1 o INSTALLING THE SMARTSENSOR 105 Attaching the Mount Bracket to the PoleFigure 1.2 – NoteDepending on the site and type of trac, the sensor may tend to over- or undercount. If the sensor is overcounting, reduce the height of the sensor by three ft. (0.9 m) and recongure the sensor. If the sensor is undercounting, increase the height of the sensor by three ft. (0.9 m) and recongure. Normally, reducing the height of the sensor improves performance.Attaching the Sensor to the Mount BracketUse the following steps to securely fasten the sensor to the mount bracket (see Figure 1.3).Align the bolts on the back of the SmartSensor with the holes in the 1 mounting bracket. The large 25-pin connector on the SmartSensor should be pointing towards the ground.Place the lock washers onto the bolts after the bolts are in the mounting 2 bracket holes.Thread on the nuts and tighten.3

Be sure to wipe o any excess compound.Applying Silicon Dielectric CompoundFigure 1.5 – Connecting the SmartSensor CableAach the cable connector to the 25-pin connector at the base of the 1 SmartSensor as shown in Figure 1.6. The SmartSensor connector is keyed to ensure proper connection; simply twist the connector clockwise until you hear it click into place.Strap the cable to the pole or run it through a conduit to avoid undue 2 movement from wind and reduce cable strain.Attached CableFigure 1.6 –

2In this ChapterConnecting 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. Wavetronix Click! products allow you to quickly and easily connect power and surge protection to your sensor application. Please refer to the Click! quick-start guides for more comprehensive product instructions. Chapter 9 contains information on how Click! products make the sensor compatible with all standard control cabinets. A pinout diagram showing the sensor cable’s pinout and appropriate connection points can be found in Appendix A of this document.Connecting Lightning Surge ProtectionIt is strongly recommended that the sensor be connected to a surge protection device. The Wavetronix Click! 200 and equivalent devices are designed to prevent electrical surges conducted along underground cables from damaging the sensor and/or the cabinet. The service end of the sensor cable should be connected to the PROTECTED side of the Click! 200 in a cabinet mounted on the sensor pole. This will help protect the sensor when lightning strikes the ground in the vicinity of the cabinet (see Figure 2.1). Connecting Power and Surge Protection

CHAPTER 2 o CONNECTING POWER AND SURGE PROTECTION 20SmartSensorUnderground CableProtecting the SensorFigure 2.1 – NoteIf 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 trac cabinet via an underground homerun cable. To protect the trac cabinet, a second surge device is strongly recommended. Follow the steps below to include surge protection using Click! 200 devices (see Figure 2.2):Install one Click! 200 device in a pole-mount box on the same pole as the 1 sensor being protected.Install another Click! 200 in the main trac cabinet. 2 Connect the SmartSensor cable from the sensor to the PROTECTED side of 3 the Click! 200 in the pole-mount cabinet. The SmartSensor cable should be kept as short as possible.Connect a SmartSensor cable from the UNPROTECTED side of the Click! 4 200 on the pole to the UNPROTECTED side of the Click! 200 in the main trac cabinet.

CHAPTER 2 o CONNECTING POWER AND SURGE PROTECTION 21SmartSensor120 VACMain Traffic CabinetPoleMountTrafficCabinetBoth ends of the homeruncable connect to theUNPROTECTED side ofthe surge modules.Typical Cable RunFigure 2.2 – The Click! 200 contains three terminal connectors on both the top and the boom of the module (see Figure 2.3). The terminal connectors are removable and are red-keyed, allowing the connector to plug into only one specic jack. This both simplies the wiring process and reduces the possibility of wiring errors.The back four terminals consist of one +DC power, -DC and two surge ground connections; the middle four terminals are for RS-485 communication and consist of a +485 connection, a -485 connection, an RS-232 ground connection and a surge ground connection; the front four terminals are for RS-232 communication and consist of TD, RD, CTS and RTS.

CHAPTER 2 o CONNECTING POWER AND SURGE PROTECTION 22Surge Protected Terminal Connections (Top)Figure 2.3 – 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.NoteSee 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.Wiring to Earth GroundALL 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 aached to a 7-ft. (2.1-m) grounding rod. Follow the steps below to correctly wire to earth ground:Connect the grounding wire from either the DIN rail or a GND screw 1 terminal on the UNPROTECTED side of the Click! 200 to the lug bolt on the inside of the pole-mount box. Connect another grounding wire from the exterior lug bolt to earth ground 2 (see Figure 2.4).

CHAPTER 2 o CONNECTING POWER AND SURGE PROTECTION 23Earth Ground ConnectionsFigure 2.4 – Connecting AC Power ConversionSince 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WarningMake sure power to AC mains is disconnected while wiring the AC input.A Click! 201 provides 1 amp of power and is capable of powering a single sensor, while a Click! 202 provides 2 amps and can power two sensors. The 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.Depending on your conguration, these Click! modules may be mounted in the pole-mount cabinet or the main trac cabinet. When mounted in the main trac cabinet, a homerun cable is used to conduct DC power and communication signals to the pole-mount cabinet. For connections shorter than 600 ft. (182.9 m), use the SmartSensor cable as your homerun cable. This will simplify the wiring process and ensure reliable connections.

CHAPTER 2 o CONNECTING POWER AND SURGE PROTECTION 24CautionAn authorized electrical technician should perform installation and operation of this unit. Persons other than authorized and approved electrical technicians should NOT aempt 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 a Circuit Breaker and SwitchThe Click! 210 is a compact circuit breaker DIN rail device designed to interrupt an electric current under overload conditions. The breaker is trip-free and can be easily reset after a current interruption by pushing the reset buon. To add a Click! 210 circuit breaker and switch (see Figure 2.5):Mount the Click! 210 onto the DIN rail.1 Connect power in to either side of the module.2 Connect power out to the other side.3 AC Surge ProtectionFigure 2.5 – Wiring AC Surge ProtectionTo include AC surge protection in your installation (see Figure 2.3):Mount the Click! 230 onto the DIN rail.1 Connect the line conductor (hot) from the Click! 210 to terminal 5 on the IN 2 side of the Click! 230. Connect the neutral wire from the AC terminal block or cord to the 3 terminal marked 1 on the Click! 230.

CHAPTER 2 o CONNECTING POWER AND SURGE PROTECTION 25Connect the ground wire from the AC terminal block or cord to the 4 terminal marked 3 on the Click! 230.Connect the outgoing and protected line wire to the terminal marked 2 on 5 the Click! 230.Connect the outgoing and protected neutral wire to the terminal marked 6 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. There is no need for any additional grounding between terminals 3 and 4 and the DIN rail.Wiring AC Power Into the Click! 201/202Follow the steps below to properly wire an AC to DC power conversion module (see Figure 2.6):Mount the Click! 201/202 onto the DIN rail.1 Connect the line (hot) wire from the Click! 230 into the L screw terminal on 2 the top of the Click! 201/202. The line wire is usually black.Connect the neutral wire from the Click! 230 to the N screw terminal to the 3 top of the Click! 201/202. The neutral wire is usually white.Wiring AC Power into the Click! 201/202Figure 2.6 – NoteThe NC screw terminal is not connected internally. Connecting a wire to a no connect (NC) terminal simply gives it a convenient termination point.Wiring DC Power Out of the Click! 201/202Connect a +DC conductor (usually a red wire) to the + screw terminal on 1 the boom of the Click! 201/202 (see Figure 2.7).

CHAPTER 2 o CONNECTING POWER AND SURGE PROTECTION 26Connect a -DC conductor (usually a black wire) to either of the - screw 2 terminals on the boom of the Click! 201/202.Wiring DC Power Out of the Click! 201/202Figure 2.7 – NoteDo not use the screw terminal marked DCOK; it provides only 20 mA and should be used only for monitoring the power supply.The screw terminal connectors on the top and boom of the module are removable to simplify wiring and are red-keyed, allowing the connector to plug into only one correct jack.Connecting DC PowerTo power the sensor, 10-30 VDC needs to be connected to the Click! 200 in the pole- mount cabinet. Additionally, if there is a main trac cabinet connected by a homerun cable, you will need to connect DC power to the Click! 200 in that cabinet.In the Pole-Mount CabinetWhether DC voltage comes from a homerun cable or from a Click! 201/202 within the pole-mount cabinet, you can always wire the DC wires to the last screw terminal on the UNPROTECTED side of the Click! 200 module. This will protect your sensor from surges. To wire DC power into the Click! 200: Connect +DC (usually a red wire) to the +DC screw terminal. 1 Connect -DC (usually a black wire) to the GND screw terminal next to the 2 +DC terminal.

CHAPTER 2 o CONNECTING POWER AND SURGE PROTECTION 27If 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): Connect +DC (24 VDC) to the top screw terminal. 1 Connect –DC to the second screw terminal.2 Green Gray+24V DC-DC +485-485GND(black wire)(red wire)Connecting Power Directly to the T-busFigure 2.8 – NoteGreen T-bus connectors provide power and communication connectivity on the DIN rail backplane; gray T-bus connectors only provide power connectivity and are used to distribute power without connecting communication.In the Main Trafc CabinetIf DC voltage is sent across a homerun connection, AC power conversion is provided in the main cabinet. In the main cabinet, the DC wires out of the Click! 201/202 should be wired to the PROTECTED side and the homerun cable should be connected to the UNPROTECTED side of the Click! 200. NoteThe purpose of the Click! 200 in the main cabinet is not to protect the sensor, but the electrical equipment inside of the main cabinet.The last screw terminal block on the PROTECTED side of the Click! 200 module contains a +DC, -DC and two surge ground connections (see Figure 2.9). Connect +DC (usually a red wire) to the +DC screw terminal. 1 Connect -DC (usually a black wire) to the GND screw terminal next to the 2 +DC terminal.

CHAPTER 2 o CONNECTING POWER AND SURGE PROTECTION 28Wiring DC Power into the Click! 200Figure 2.9 – Wiring CommunicationAfter 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. In addition, the sensor’s native RS-485 connection is available in the pole mount cabinet via the following three ports on the Click! 200:Screw terminals on the boomRJ-11 connector on the faceplateT-bus backplane NoteThe Click! 200 does not convert RS-232 communication to RS-485. It simply provides surge protection for these two independent connections.One common way to connect communications back to a main cabinet is to use a SmartSensor cable as your homerun cable. See Appendix C for information about maximum cable lengths for wired communication. Wavetronix Click! products facilitate a wide variety of additional wired and wireless communication options. Contact a Wavetronix-authorized technical representative to nd out which options are best suited for your application. Contact Closure ConnectionsWhile any of the RS-485 ports on the Click! 200 can be connected to contact closure modules, it is often easiest to connect from the RJ-11 port. In some cases, several contact closure cards can be daisy-chained together. However, the chain

CHAPTER 2 o CONNECTING POWER AND SURGE PROTECTION 29should not be connected until each card has been independently programmed (see Figure 2.10). Connecting Contact Closure ModulesFigure 2.10 – NoteWait to connect contact closure communications until after the sensor is programmed using the conguration software. See Chapter 9 for more information on contact closure communications.
