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 specifically 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 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 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 off 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 configured to operating using different RF channels and are separated vertically by a few feet. The higher sensor would typically be used for the lanes further from 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. 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 reflection paths from a single vehicle. Mounting Height – The mounting height should be based upon the offset from the lanes of interest. For each offset, 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 Offset – The minimum recommended offset from the edge of the first 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. Figure I.1 – Portable (left) and Permanent (right) Sensor Stations 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 8 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. For longer connections, alternate wired and wireless options should be considered.

Follow the steps below to correctly attach the mount to the pole (see Figure 1.2): Look up the recommended mounting height from Table 1.1. Insert the stainless steel straps through the slots in the mount bracket. Position the mount on the pole so that the head of the mount is pointing towards the middle of the lanes of interest. Tighten the strap screws. 15 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. Attaching the Sensor to the Mount Bracket Use 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 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 bracket holes. Thread on the nuts and tighten. 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 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. Tighten mounting bracket bolts. 17 18 CHAPTER 1 o INSTALLING THE SMARTSENSOR 105 Applying Silicon Dielectric Compound Use the following steps to correctly apply the silicon dielectric compound: 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 1.5 – Applying Silicon Dielectric Compound Connecting the SmartSensor Cable Attach the cable connector to the 25-pin connector at the base of the 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 movement from wind and reduce cable strain. Figure 1.6 – Attached Cable Connecting Power and Surge Protection 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. Wavetronix Click! products allow you to quickly and easily connect power and surge protection to your sensor application. Please refer to the Click! quickstart 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 Protection It 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). 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. 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 sensor being protected. Install another Click! 200 in the main traffic cabinet. Connect the SmartSensor cable from the sensor to the PROTECTED side of 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! 200 on the pole to the UNPROTECTED side of the Click! 200 in the main traffic cabinet. 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. This both simplifies 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. 21 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. 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-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 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 (see Figure 2.4). 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. 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 off. Depending on your configuration, these Click! modules may be mounted in the pole-mount cabinet or the main traffic cabinet. When mounted in the main traffic 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. 23 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. Wiring a Circuit Breaker and Switch The 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 button. To add a Click! 210 circuit breaker and switch (see Figure 2.5): Mount the Click! 210 onto the DIN rail. Connect power in to either side of the module. Connect power out to the other side. Figure 2.5 – AC Surge Protection Wiring AC Surge Protection To include AC surge protection in your installation (see Figure 2.3): Mount the Click! 230 onto the DIN rail. Connect the line conductor (hot) from the Click! 210 to terminal 5 on the IN side of the Click! 230. Connect the neutral wire from the AC terminal block or cord to the terminal marked 1 on the Click! 230. CHAPTER 2 o CONNECTING POWER AND SURGE PROTECTION 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. There is no need for any additional grounding between terminals 3 and 4 and the DIN rail. Wiring AC Power Into the Click! 201/202 Follow 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. Connect the line (hot) wire from the Click! 230 into the L screw terminal on 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 top of the Click! 201/202. The neutral wire is usually white. Figure 2.6 – Wiring AC Power into the Click! 201/202 Note The 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! 201/202 Connect a +DC conductor (usually a red wire) to the + screw terminal on the bottom of the Click! 201/202 (see Figure 2.7). 25 26 CHAPTER 2 o CONNECTING POWER AND SURGE PROTECTION 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. The screw terminal connectors on the top and bottom of the module are removable to simplify wiring and are red-keyed, allowing the connector to plug into only one correct jack. Connecting DC Power To power the sensor, 10-30 VDC needs to be connected to the Click! 200 in the polemount cabinet. Additionally, if there is a main traffic cabinet connected by a homerun cable, you will need to connect DC power to the Click! 200 in that cabinet. In the Pole-Mount Cabinet Whether 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. Connect -DC (usually a black wire) to the GND screw terminal next to the +DC terminal. 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): 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 2.8 – Connecting Power Directly to the T-bus Note Green 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 Traffic Cabinet If 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. Note The 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. Connect -DC (usually a black wire) to the GND screw terminal next to the +DC terminal. 27 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. 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 bottom RJ-11 connector on the faceplate T-bus backplane Note The 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 find out which options are best suited for your application. Contact Closure Connections While 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 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.
