14 CHAPTER 1 • INSTALLING THE SMARTSENSOR MATRIX Warning Use caution when installing any sensor on or around active roadways. Serious injury can result when installation is performed using methods that are not in accordance with authorized local safety policy and procedures. Always maintain an appropriate awareness of the traffic conditions and safety procedures as they relate to specific locations and installations.
CHAPTER 1 • INSTALLING THE SMARTSENSOR MATRIX ˽˽ Take into consideration the sensor’s field of view, which reaches 140 ft. (42.7 m) from the sensor. Place the sensor so that the field of view covers all the areas of interest. ˽˽ The mast arm is frequently a good place to mount the sensor. ˽˽ The mounting position should have a clear view of the detection area. Poles, mast arms, signal heads, or other objects should not block the view of the detection area.
16 CHAPTER 1 • INSTALLING THE SMARTSENSOR MATRIX One swivel joint is used to pan the sensor field of view left or right and the other swivel joint is used to tilt the sensor down towards the roadway. If you are not using the double swivelmount, make sure the pole straps are adjustable at this point in the installation process.

If more of a visual indicator is needed, then a square framing tool (e.g. rafter square) or other tool with a right angle can be held above the sensor.
18 CHAPTER 1 • INSTALLING THE SMARTSENSOR MATRIX 2 3 downstream of the stop bar. Tilt the sensor down so it is aimed at the center of the lanes of interest. If necessary, rotate the sensor so that the bottom edge of the sensor is parallel with the roadway. This is necessary where the intersection approach has a significant grade.
CHAPTER 1 • INSTALLING THE SMARTSENSOR MATRIX Figure 1.6 – Sensor 6-conductor Cable Connector To set up your network in an orderly fashion, it is recommended that labeling be used on the service end of each SmartSensor 6-conductor cable. A convenient way to label the cables is to mark the last seven digits of the serial number on each sensor and the direction of traffic monitored (see Figure 1.7). Figure 1.
20 CHAPTER 1 • INSTALLING THE SMARTSENSOR MATRIX Caution Be careful of Electrostatic Discharge (ESD) when handling the SmartSensor Matrix device before and during installation. ESD triggered by the sensor handler, particularly on the outer grounding lug before being properly grounded, may cause harmful effects to internal Matrix components.
Connecting Power and Surge Protection 2 In this chapter ˽˽ ˽˽ ˽˽ ˽˽ Mounting the Backplate Connecting AC Power Providing System Surge Protection Terminating SmartSensor 6-conductor Cables 2 After installation, each SmartSensor Matrix will need to be integrated into the main traffic cabinet for power and surge protection.
22 CHAPTER 2 • CONNECTING POWER AND SURGE PROTECTION Figure 2.1 – Intersection Preassembled Backplate Mounting the Backplate Use the following steps to mount the backplate in the traffic cabinet: 1 2 Locate the area planned for mounting the backplate. The backplate can usually be mounted on the side panel of a NEMA-style cabinet. Attach the backplate with the U-channel mounting screws.
CHAPTER 2 • CONNECTING POWER AND SURGE PROTECTION Warning Make sure power to AC mains is disconnected while wiring the AC input. If your installation does not require AC power, you will need to use surplus DC power inside the traffic cabinet. In this case, Wavetronix recommends you use the Click 221 (8 A DC surge protector) to protect the backplate and SmartSensor Matrix units from DC surges. See Appendix C for information regarding the Click 221. Figure 2.
24 CHAPTER 2 • CONNECTING POWER AND SURGE PROTECTION Caution An authorized electrical technician should install the preassembled backplate. Persons other than authorized and approved electrical technicians should NOT attempt to connect the backplate 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 the backplate to an active power supply.
CHAPTER 2 • CONNECTING POWER AND SURGE PROTECTION Follow the steps below to provide a low impedance protective earth connection: 1 2 Connect one end of a protective earth ground wire to the bottom of the PE terminal block.

Contact Closure Communication 3 In this chapter ˽˽ ˽˽ ˽˽ ˽˽ ˽˽ Using the Click 112/114 DIP Switches Using the Click 104 Rotary Switch Attaching and Programming the Click 112/114 Attaching and Programming the Click 104 Channel Mapping 3 Each SmartSensor Matrix communicates with standard traffic cabinets using either the Click 104 DIN rail contact closure module or the Click 112/114 detector rack cards (see Figure 3.1).
32 CHAPTER 3 • CONTACT CLOSURE COMMUNICATION Note See the Click 100–400 Series User Guide for complete information on how to connect and configure the Click 104 DIN rail contact closure module and the Click 112/114 detector rack cards. Each SmartSensor Matrix could potentially use up to 16 channels using a combination of Click 104/112/114 contact closure modules. This means that a standard four-approach stop bar detection system can be accommodated by a 64-channel detector rack.
CHAPTER 3 • CONTACT CLOSURE COMMUNICATION Note An advantage of using the DIP switches for configuration is that if you ever need to replace a Click 112/114, you can simply set the DIP switches on the new card to match the pattern of the DIP switches on the card you are replacing, then slide the new one into the same slot in the detector rack. Click 114 Input Mapping DIP Switch Settings On a Click 114, channel group 1 comprises input channels 1–4.

This will assign sensor output channels 3 and 4 for output.
CHAPTER 3 • CONTACT CLOSURE COMMUNICATION As shown in the table below, the outputs are mapped sequentially—that is, they can only be mapped in numerically ordered groups of four (1–4, 5–8, etc.). If you set the switch to 3, for 9–12, then sensor channel 9 would be mapped to output 1, sensor channel 10 would be mapped to output 2, sensor channel 11 would be mapped to output 3, and sensor channel 12 would be mapped to output 4.
36 CHAPTER 3 • CONTACT CLOSURE COMMUNICATION 4 5 6 7 Connect a 6-ft. (1.8-m) patch cord from the Click 222 RS-485 B port to a bus 1 port on another rack card. If you are using Click 112 cards, use an 6-in. (15-cm) patch cord to share bus 1 between cards dedicated to the same sensor. Also, configure one card to use Matrix channels 1 and 2 and configure the other card to use Matrix channels 3 and 4.
CHAPTER 3 • CONTACT CLOSURE COMMUNICATION Detection Channel Menu Level 2 Menu Level 1 Mode Switch Figure 3.7 – Click 112/114 Menu Normally, a SmartSensor Matrix sensor will send 10 contact closure messages each second. If a rack card does not receive communications from a sensor within 10 seconds, the rack card will go into fail-safe mode and all of the contact closures will be activated and the corresponding detection channel LEDs on the faceplate will turn on.
38 CHAPTER 3 • CONTACT CLOSURE COMMUNICATION 3 If needed, daisy-chain multiple Click 104 devices together by utilizing both RJ-11 jacks on each device’s faceplate. Click 104 LEDs The front panel of the device features a push-button and three banks of LEDs for on-device configuration and monitoring.

9 Verification In this chapter ˽˽ Channel Indicators ˽˽ Verification Menu Bar 9 After the configuration is complete, you will need to verify that the sensor was configured correctly. To verify lane configuration and channel mapping, click on tab 3. This will bring up the Verification window (see Figure 9.1). Figure 9.1 – Verification View In the Verification window, vehicle detections will appear as light blue rectangles.
90 CHAPTER 9 • VERIFICATION Vehicle detections in a stopped queue are represented by a stationary light blue rectangle. Channel Indicators When detections enter a zone, they will cause the indicators for the channel mapped to that zone to turn red. To see the zones mapped to a particular channel, select that channel by clicking on its indicator (see Figure 9.2). Active zones for the selected channel will be red; inactive zones for the selected channel will be gray.
CHAPTER 9 • VERIFICATION Figure 9.3 – Delay and Extend Zone Settings When vehicles stop before and after a zone, the stopped vehicle queue is extended to fill the space between the two vehicles. This ensures that a queue of vehicles that extends in front and behind a zone will always activate the zone even if the vehicles are not directly over it (see Figure 9.4). Stopped Vehicle Stopped Vehicle Queue Extension Stopped Vehicle Figure 9.

Appendix In this chapter ˽˽ ˽˽ ˽˽ ˽˽ ˽˽ Appendix A –Cable Connector Definitions Appendix B –Cable Lengths Appendix C – Click 221 User Reference Guide Appendix D – Click 600 Installation Appendix E - Matrix Extended Range 11 Appendix A – Cable Connector Definitions The connector end of the SmartSensor 6-conductor cable mates to the 8-pin connector on the SmartSensor Matrix (see Figure A.1).
102 APPENDIX G A H B F C E D Figure A.1 – SmartSensor Matrix Connector The SmartSensor 6-conductor cable has seven wires. Table A.1 details the pinout of the cable connector and the corresponding wire in the cable. The sensor itself also contains internal wires that connect to the protective earth lug.
APPENDIX 3 4 Strip each of the seven SmartSensor cable wires back about 1/4 in. (0.6 cm). Insert the wires into the contacts and verify the wire is visible through the contact inspection hole. 5 Crimp the wires by following the crimping tool instructions. Daniels Manufacturing Company provides professional grade crimping tools and detailed instructions on crimping. Wavetronix recommends the DMF AF8 M22520/1-01 or equivalent tool for crimping.
104 APPENDIX Note Contact Wavetronix Technical Services if you have a need for a cabled connection over 500 ft. (152.4 m). Appendix C – Click 221 User Reference Guide The Click 221 is a DC 8 A surge protector (8 A is the maximum rating of a T-bus connector). The DC source voltage and PE (protective earth) should be wired into the screw terminals on the bottom side of the device. A 12 AWG protective earth wire is recommended. The device works with up to 8 A of continuous current at a maximum of 28 VDC.
APPENDIX (reverse polarity), the device is not powered or the surge protection circuitry is no longer operational. If the LED flickers on an then off when power is applied, this means that the device is conducting power, but the surge is no longer fully functional. When the surge is no longer fully functional, please contact Wavetronix Technical Services for assistance.
106 APPENDIX During normal operation, be sure that all appropriate switches are turned on. Caution An authorized electrical technician should install the preassembled backplate. Persons other than authorized and approved electrical technicians should NOT attempt to connect the backplate 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.
APPENDIX configure the sensor, and lets the sensor send its detection data back to the cabinet. Before you can plug in the cables, you’ll need to terminate each one into the terminal blocks included with your Click 600. The method for doing this is identical to the method used with the preassembled backplates, so for detailed instructions on how to terminate the cables, please see the Terminating SmartSensor 6-conductor Cables section in chapter 2 of this guide.
108 APPENDIX Note You don’t have to do anything special to tell the device to push data on any port; all data received on any port is automatically pushed on all other ports. The data bus portion of the faceplate also has the following features: next to each RJ-11 jack is a switch that turns power on and off to the associated sensor; under each jack is an LED that illuminates when the associated sensor has power.
APPENDIX 3 4 Insert the other end of each wire into a second 5-position connector. Plug one connector into the T-bus port on the Click 600; plug the other into the end of your T-bus. Lastly, there are four LEDs on the faceplate.
110 APPENDIX 26' 200 ft 15' 18' 140 ft 13' 11' 100 ft 8' Figure E.1 – Matrix Beam Footprints In an installation where the SmartSensor Matrix is installed in its preferred stop bar location, angular resolution will likely not be a problem. This is because as the vehicles approach the stop bar they will pass through the middle of the sensor’s view and be resolved.
APPENDIX 200 ft 140 100 ft ft Figure E.2 – Dual Approach Monitoring Signal-to-Noise Ratio and the Stop bar Effect The SmartSensor Matrix collects data beyond its advertised range. However, the signal-tonoise ratio, or the signal-to-clutter ratio, is not large enough at the far ranges to consistently detect a vehicle. This means that even though the sensor does detect some energy, the UI doesn’t show constrained trackers.
112 APPENDIX Example A semi truck is is situated in a left turn lane and its far edge is 30 feet from the sensor. If the sensor is mounted 20 feet above the roadway and a 13-foot tall semi is in the lane closest to the sensor, then a vehicle that is 5 feet tall would be fully occluded within a 34 foot area. Now, in that same situation, if the lane is placed so that the far edge of the semi is at 60 feet, then the occluded ground range is doubled to 68 feet.
APPENDIX 2 Perform a batch upgrade of sensors to a new version of firmware. As a simple example, a Microsoft Windows batch file can be used to sequentially upgrade all the sensors listed in the file. Note The auto upgrade command line feature will connect to one sensor at a time and upgrade if necessary. If connection is successful but upgrade is not necessary, then SSMA will automatically close the connection and shut down.
