12 Intersection Equipment Installation Instructions 9 3 Description This section provides a general description of the Opticom GPS system and a detailed description of the intersection equipment. Opticom GPS System The Opticom GPS system assists authorized priority vehicles through signalized intersections by providing temporary right-ofway through the use of common traffic controller functions. The Opticom GPS system consists of the following matched components: Vehicle Equipment Radio/GPS unit containing a GPS receiver and a 2.4 GHz transceiver Radio/GPS antenna Vehicle Control unit Intersection Equipment A traffic pole mounted Radio/GPS unit containing a GPS receiver with antenna and a 2.4 GHz transceiver with antenna (Model 1010) Or a Traffic Cabinet mounted Radio/GPS unit containing a GPS receiver and a 2.4 GHz transceiver (Model 1012) Radio/GPS antenna (Model 1050) Phase Selector (Model 1000) Card Rack/Input File (Model 1040) The vehicle equipment is mounted on the priority vehicle. Its GPS receiver acquirers position information from the constellation of GPS satellites. This information is used to compute the location, speed, and heading of the vehicle. This information, along with a priority request and the state of the vehicles turn signal, is broadcast using the 2.4 GHz transceiver. The intersection equipment receives the radio transmission from the vehicle equipment. The intersection equipment then compares the information being received from the vehicle to the parameters stored in the intersection equipment s memory. If the vehicle is heading toward the intersection in a predefined approach corridor, is requesting preemption and has met all other programmed parameters, the corresponding phase selector output is activated. This output is connected to the traffic controller preemption input. When activated, the controller cycles to grant a green light to the requesting vehicle or holds the green allowing the vehicle to pass through the intersection. The card rack/input file provides the power and logic wiring for the phase selector, which plugs directly into a slot in the unit. The auxiliary interface panel provides additional connection for monitoring green phases and also provides additional priority control outputs. The auxiliary harness can be used to provide additional connection for monitoring green phases when the auxiliary interface panel is not required. Auxiliary Interface Panel (Model 1030) Green Sense Harness (Model 1035)

13 10 Intersection Equipment Installation Instructions 3.1 Intersection Equipment The Opticom GPS System intersection equipment has two styles of Radio/GPS units available. The first is the Model 1010, which is a compact, weather-resistant, Radio/GPS unit containing a GPS receiver with antenna and a 2.4 GHz transceiver with antenna. This model is typically mounted on a traffic pole near the traffic cabinet. The second is the Model 1012 Radio/GPS unit, which contains a GPS receiver, a 2.4 GHz transceiver and a separate Radio/GPS antenna. This model is mounted in the traffic cabinet with the antenna mounted on the roof of the cabinet. Both models of the Radio/GPS unit are connected to a phase selector via an 11-conductor radio/gps cable. The phase selector can be installed directly into an input file of a traffic controller equipped with priority phase selection software. The phase selector can also be installed directly into virtually any other traffic controller equipped with priority phase selection inputs and related software. When input file space is not available, a card rack is required. The phase selector is powered by +24 VDC. A power supply in the card rack or an external power supply provides the +24 VDC. This manual describes the installation of the radio/gps unit, a card rack (when required), and installation of a phase selector into either a card rack or a Type 170 input file. Figure 3-1 shows the phase selector installation components including the phase selector, card rack, input file, auxiliary interface panel, and the wiring harnesses and cables. The 9-pin harness connects the card rack to the traffic controller. The communication cable connects the phase selector to a PC. Additional communication connections are available on the auxiliary interface panel. The auxiliary interface panel cable connects the phase selector to the auxiliary interface panel. The auxiliary harness connects green sense inputs to the phase selector. The radio/gps cable connects the phase selector to the intersection radio/gps unit. A customer-supplied 24 VDC power cable connects the phase selector to an external power supply, which is required when the phase selector is plugged directly into an input file of a traffic controller cabinet that does not have 24 VDC on the edge connector. NOTE: Illustrations and connections to the traffic controller may not be exactly as shown or described in this manual. Refer to the controller wiring diagram for correct terminal connections. The phase selector processes the signal from the radio/gps unit and activates outputs which are connected to the preemption inputs on the traffic controller. There are four channel outputs accessible on the rear connector of the phase selector and up to 12 additional channel outputs accessible on the front of the phase selector. Each channel output delivers a constant output for high priority activation, and a pulsed output for low priority activation. A high priority signal received on a channel will override any low priority activation. In certain modes of operation, outputs may be activated that are dependent on the state of the requesting vehicle s turn signal. Another mode provides separate outputs for high priority and low priority. The use of an auxiliary interface panel is required to access these additional modes and outputs.

There are two models of approaching. See Figure 5-1. the Radio/GPS unit. See section for details on installing the Model 1012 Radio/GPS unit. Do not paint the Model 1010 radio/gps unit cover. Metals or metal oxides in the paint may 5.1 Model 1010 Radio/GPS unit mounting interfere with GPS reception and/or radio Location Considerations reception/transmission. Read and understand the following precautionary paragraphs before starting the installation. Do not modify the radio/gps unit circuitry. There are no user-serviceable parts inside. The Model 1010 radio/gps unit should be mounted in a location that has an unobstructed view of all approaches out to a distance of 2500 feet. Blockage of approaches by things such as bridges, buildings, walkways, and trees should be avoided. The Model 1010 radio/gps unit is usually mounted to the mast arm or span wire pole nearest the traffic controller cabinet. If an appropriate mounting location on a mast arm or span wire pole is not available, you can mount the unit to a span wire. Try to use a signal head or sign mount to minimize sway. The Model 1010 radio/gps unit should be mounted level and as high as possible. Do not mount the unit upside down. The Model 1010 radio/gps unit should have an unobstructed view of at least 50% of the sky. IMPORTANT NOTE Modifying the radio/gps unit may seriously damage the equipment and void the warranty. Do not attempt to modify the radio/gps circuitry in any way. Modifying the radio and/or antenna in any way may cause the radio to violate FCC/IC requirements. REMARQUE IMPORTANTE La modification du système radio/gps risque d endommager sérieusement le matériel et d annuler la garantie. Ne pas tenter de modifier les circuits du système radio/gps de quelque façon que ce soit. En modifiant le système radio et/ou l antenne de quelque façon que ce soit, la radio risque de ne plus répondre aux exigences de la FCC/IC. The mounting location should be such that the cable run from the radio/gps unit to the phase selector (located in the traffic controller cabinet) is no more than 250 feet. The radio/gps cable may be run through conduit or attached to a messenger wire. The cable should not be suspended unsupported.

20 Intersection Equipment Installation Instructions Model 1010 Radio/GPS Unit Installation This section describes how to install the Opticom GPS System Model 1010 Radio/GPS Unit. See section for details on installing the Model 1012 Radio/GPS unit. NOTE: The mounting location must provide a 3/4-inch NPT internal thread mount. Mounting brackets, nipples, pipe and lock nuts are not included. Choose the mounting location. This is usually the mast arm or span wire pole nearest the traffic controller cabinet. The cable run from the radio/gps unit to the phase selector (located in the traffic controller cabinet) should not exceed 250 feet. Screw a nipple (or pipe) into the base of the radio/gps unit. Use pipe thread tape to waterproof the joint. Loosen the two cover screws and remove the wiring cover. Route the radio/gps cable from the radio mounting location to the traffic controller cabinet. The cable can enter the radio/gps unit either through the cable retainer in the wiring cover or through the nipple/pipe at the base of the unit. See Figure 5-5. In either case, the wiring connections are the same. For purposes of discussion, these instructions assume the cable enters the radio/gps unit through the cable retainer. Figure 5-5.

21 18 Intersection Equipment Installation Instructions Screw the nipple/pipe at the base of the radio/gps unit into the threaded NPT mount. Use pipe thread tape to waterproof the joint. Do not tighten the locknuts yet. Disassemble the weather-tight cable retainer and route the cable through the compression nut, plastic washer, rubber bushing, and into the cover as shown in Figure 5-6. Leave approximately 4 inches of cable inside the cover and tighten the compression nut to secure the cable. Strip approximately 3 inches of the outer jacket from the end of the cable. Be careful not to cut the wires inside. Make sure the outer jacket is held in place by the rubber bushing. Strip 1/4 inch of insulation from each wire. NOTE: It is very important to not strip too much insulation, which may lead to short circuits; or too little insulation, which may prevent the wire from making good contact. Place each wire into the appropriate hole in the 11-pin terminal block and tighten the screw to secure the wire. The label on the terminal block shows the color of each wire. Table 5-1 also shows the terminal block pin number, wire color, and function of each wire. The terminal block may be removed to allow easier connections. Figure 5-6.

23 20 Intersection Equipment Installation Instructions 5.3 Model 1012 Radio Installation This section describes how to install the Model 1012 version of the Opticom GPS radio. Important Note: The Model 1012 radio is designed to be installed directly inside of the traffic cabinet with the antenna mounted on the roof of the cabinet. This style radio should only be installed if it is determined from a site survey that the location will not overly degrade GPS reception and or radio transmission and reception. Since the antenna is mounted at the height of the top of the traffic cabinet rather than at the height of the traffic signals, the antenna s view of the sky (for GPS reception) may be less. Also by mounting the antenna lower, obstacles such as buildings, trees etc., will likely reduce radio range. If it is determined by survey of the intersection that these reductions will still allow the Opticom GPS system to operate satisfactorily, then the Model 1012 may be installed. If not, it is recommended that a Model 1010 radio be used. IMPORTANT NOTE Modifying the radio/gps unit may seriously damage the equipment and void the warranty. Do not attempt to modify the radio/gps circuitry in any way. Modifying the radio and/or antenna in any way may cause the radio to violate FCC/IC requirements. REMARQUE IMPORTANTE La modification du système radio/gps risque d endommager sérieusement le matériel et d annuler la garantie. Ne pas tenter de modifier les circuits du système radio/gps de quelque façon que ce soit. En modifiant le système radio et/ou l antenne de quelque façon que ce soit, la radio risque de ne plus répondre aux exigences de la FCC/IC Model 1050 Antenna mounting NOTE: 1. Do not paint the radio/gps antenna cover. Metals or metal oxides in the paint may interfere with GPS reception and/or radio reception and transmission. 2. Be sure to capture metal shavings when drilling a hole in the cabinet. Antenna mounting factors: The antenna must be mounted on the top of the cabinet so that the GPS antenna has a good view of the sky. To minimize possible vandalism, mount it in a location that is the least visible. 1. Remove the nut and washer from the Radio/GPS antenna. 2. Drill a 5/8 to 3/4 inch hole in the top of the cabinet. See Figure Route the cables through the hole and replace the lock washer and nut. 4. Tighten the nut with a 15/16 inch wrench (a 24 mm wrench may be used if a 15/16 inch wrench is not available). Note: Do not over tighten the nut or the antenna may be damaged. 5 ft/lbs is the recommended torque. 5. Apply silicone RTV (not provided) around the antenna to provide a good seal with the antenna s built-in gasket.

27 24 Intersection Equipment Installation Instructions 5.4 System Configurations This section describes two configurations for installing Opticom GPS System Phase Selectors: Type 170 controller installations and NEMA controller installations. Determine which configuration applies to your system, then go to the section number shown for the installation instructions. NOTE: Read through the section for your configuration and perform the applicable installation procedures, then go to Section 8 to check out the installation Type 170 Controller Installations CA/NY Type 170 controller cabinets (and some NEMA cabinets) have input files that will accept one phase selector. Logic wiring is factory installed in the cabinet for the phase selector. Power for the phase selector is provided by an external power supply Phase Selector Installation WARNING Improper or incomplete programming of the traffic controller may cause improper operation of the traffic signals, which may result in accidents and/or injuries. To avoid this problem, verify that the operation of the traffic controller is appropriate for your needs before, during, and after actuation of the priority control inputs. Improper operation of the traffic signals may result in unsafe driver action. See Section 5.4 for installation of phase selectors into Type 170 controllers NEMA Controller Installations NEMA controllers with priority control inputs usually require a card rack. Each phase selector plugs directly into the card rack. The card rack wiring harness provides inputs and outputs to the traffic controller system hardware. See Section 5.5 for installation of phase selectors into NEMA controllers. 5.5 Installation Type 170 Controllers These instructions include: Installing the phase selector. See Section Connecting the radio/gps cable to the phase selector. See Section Installing the auxiliary interface panel. See Section Wiring for green sense. See Sections and Two input file slots are dedicated for use by Opticom GPS System Phase Selectors. These slots are usually J12 and J13 in the lower input file. They are pre-wired and have a direct association with particular priority control inputs to the traffic controller. Both J12 and J13 supply two priority control inputs to the traffic controller. Refer to your cabinet drawings to verify the slots, which are usually referred to as EVA, EVB, EVC, or EVD. The outputs from the phase selector are connected to the preemption inputs of the traffic controller. Each phase selector output must be connected to a separate controller preemption input. Consult the manual for your controller to determine if the preemption inputs are handled with the same priority. For some traffic controllers, preemption inputs one and two are intended for railroad and draw bridge preemption and are given precedence over the rest of the preemption inputs. Cabling for remote communication. See Section

28 Intersection Equipment Installation Instructions 25 When programming your priority control routines, it is important to use values that will allow the traffic controller to respond to a priority control request as quickly and safely as possible. If the routines are not programmed to respond quickly enough, the requesting vehicle may not receive a green light in time to travel through the intersection safely. 1. Set the power switch on the front panel of the phase selector to OFF. 2. Install the phase selector into slot J13 of the lower input file, making sure it is fully seated. See Figure Figure Phase Selector Installation Using Slot J13 1. Upper input file 3. Phase selector 2. Lower input file
