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 swivel-mount, make sure the pole straps are adjustable at this point in the installation process.
Edge of first lane of interest CHAPTER 1 • INSTALLING THE SMARTSENSOR MATRIX 45° 45° Pan sensor towards stop bar Stop Bar Figure 1.3 – Corner Radar Field of View Position To visualize the extent of the sensor field of view, the 90° field of view is imprinted on the top and bottom of the sensor case. 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 1 2 3 Adjust the side-to-side angle so that the front edge of the field of view provides a view 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.
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. A 10 AWG stranded wire is recommended for protective earth ground connections and is also the largest that will fit in the terminal block. Connect the other end of the protective earth ground wire to a protective earth screw terminal within the main traffic cabinet.

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. The first bank of LEDs, labeled Channel, displays the state of the contact closure outputs (see Figure 3.8). 1 Channel 2 3 Menu 4 PWR OK TD RD Figure 3.

CHAPTER 8 • ZONES & CHANNELS Figure 8.10 – Zone/Channel Map Window Each channel column contains channel number and channel type (N=normal, C=count, P=pulse). Click on the individual zones in the zone column to highlight the zones in the edit area. Editing Channels The Edit Channel button will allow you to choose the channel type, map/un-map zones to a selected channel, and change delay/extend settings (see Figure 8.11).
88 CHAPTER 8 • ZONES & CHANNELS Figure 8.12 – Output Settings (Normal, Counting, Pulse) ˽˽ Detector Input – The Detector Input number provides a way for you to map inputs to the intersection phase in the controller. By default, the Detector Input will be set to “00;” if the input is left at “00,” then it is unassigned. This setting is for reference purposes only and does not actually change the sensor.
CHAPTER 8 • ZONES & CHANNELS The dashes in the table mean that those particular settings are disabled due to the selected channel type. Double click on any channel row to change the output settings for that channel. Measuring Zones The SSMM software contains a feature that allows you to see how large a zone is as well as a number of other distance measurements.

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.
92 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.
94 CHAPTER 9 • VERIFICATION undo your last edit, edit thresholds and pause/play traffic (see Figure 9.6). Click the button at the right side of the menu bar to see a window with menu descriptions. Figure 9.6 – Verification View Menu Bar The Verification menu bar contains the following options: ˽˽ To Main Menu – Returns you to the main menu. ˽˽ Save Config – Saves the zones and channel mapping to the sensor.
10 Tools In this chapter ˽˽ ˽˽ ˽˽ ˽˽ Backup/Restore Rack Cards Tools Tracker Logging Sensor Self Tests 10 The Tools screen allows you to back up or restore your sensor configuration, log vehicle detections, and perform several other functions (see Figure 10.1). When connected to a sensor, all the options will be active except for the Rack Card Tools option. When a sensor connection is not active, the Rack Card Tools option will be available but the other options will not. Figure 10.
96 CHAPTER 10 • TOOLS Backup/Restore To back up or restore the sensor settings that you have changed, click the Backup/Restore button on the Tools screen (see Figure 10.2). Figure 10.2 – Backup/Restore To create a backup, click on the magnifying glass icon in the Back-up File section. Choose a destination, type in a filename for your new backup and click OK, then click the Back-up Sensor Setup button. Note The backup will appear as an .mxc file.
CHAPTER 10 • TOOLS Rack Cards Tools Access tools for working with rack cards and other contact closure devices by clicking the Rack Card Tools button on the Tools screen when a sensor connection is NOT active (see Figure 10.3). Figure 10.3 – Rack Card Tools The Rack Card Tools screen allows you to verify that you have the correct channel mapping into the traffic controller, without being connected to a sensor.
98 CHAPTER 10 • TOOLS Figure 10.4 – Rack Card Tool Serial Settings 2 3 After you have entered the correct settings, close the Serial Settings window and click the Search button. Once a list of devices appears, click on the desired row. You can identify a device by its ID, Device, Description or Location fields. If you would like to communicate to all the devices, select All Rack Cards in the device column.
CHAPTER 10 • TOOLS Channel Outputs Switch The Channel Outputs toggle switch and 1–16 checkboxes are used to help assist in testing of the rack card outputs. If the Channel Outputs switch is ON, all the selected channel outputs on the Click 112/114 rack card or Click 104 contact closure device will be active. The LEDs that indicate an active output channel will light up accordingly. An output will only be active when the corresponding box is checked.
100 CHAPTER 10 • TOOLS This tool records vehicle detections as shown on the Verification page. Recorded vehicle detections can be used later for playback using a virtual connection. Click on the open folder icon to select a log file. The Select Tracker Log File screen allows you to specify the name of an existing log file or to create a new file (see Figure 10.6). Figure 10.6 – Select Detection Log File Screen Click the ON/OFF toggle switch icon to the ON position to begin logging vehicle detections.
CHAPTER 10 • TOOLS Sensor Self Tests The Sensor Self Tests screen allows you to check the sensor to verify it is working properly (see Figure 10.8). To run the sensor self test, click the Run Sensor Self Tests button. Figure 10.8 – Sensor Diagnostics The test results will appear as either “Success” or “Failed” (see Figure 10.9).
