7 2 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-of-way through the use of common traffic controller functions. The Opticom GPS system consists of the following matched components: Vehicle Equipment Components Radio/GPS unit containing a GPS receiver and a 2.4 GHz transceiver Radio/GPS antenna Vehicle Control unit Intersection Equipment Components 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) with a Radio/GPS antenna (Model 1050) Phase Selector (Model 764) Card Rack/Input File (Model 760) Auxiliary Interface Panel (Model 768) Operation Description The vehicle equipment is mounted on the priority vehicle. Its GPS receiver acquires 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, ID information 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 outputs. 7

8 Intersection Equipment Details 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 in the traffic cabinet, a card rack is required. 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. Figure 2-1 shows the intersection 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. Various communication ports are available to connect the phase selector to a PC or to remote communication equipment. 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 radio/gps cable connects the phase selector to the intersection radio/gps unit. 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. 8

10 3 Radio/GPS unit Installation This section describes the installation of the radio/gps unit. There are two models of the radio/gps unit. See section 3.2 for details on installing the Model 1012 Radio/GPS unit. 3.1 Model 1010 Radio/GPS unit mounting Location Considerations Read and understand the following precautionary paragraphs before starting the installation. 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 (762m). 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. 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 (76m). The radio/gps cable may be run through conduit or attached to a messenger wire. The cable should not be suspended unsupported. The Model 1010 radio/gps unit should be oriented such that the cable retainer is facing an area from which vehicles will NOT be approaching. See Figure 3-1. Do not paint the Model 1010 radio/gps unit cover. Metals or metal oxides in the paint may interfere with GPS reception and/or radio reception/transmission. Do not modify the radio/gps unit circuitry. There are no user-serviceable parts inside. 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. 10

12 Figures 3-2 through 3-4 show typical installations of the Opticom GPS System Intersection Model 1010 Radio/GPS Units. Figure 3-2 shows a Model 1010 radio/gps unit installed on a mast arm. The radio/gps unit should be mounted level and higher than the mast arm pole, if possible. Place the unit as far out over the intersection as possible and still provide good coverage down the cross streets. Figure 3-2. Mast Arm Installation Model

13 Figure 3-3 shows a radio/gps unit installed on a span wire pole. The radio/gps unit should be mounted level and extended about 3 feet (1m) away from the pole. Figure 3-3. Span Wire Pole Installation Model 1010 Figure 3-4 shows a Model 1010 radio/gps unit installed on a span wire. The radio/gps unit should be mounted level and higher than the upper span wire. Mount the unit so that it is as rigid and stable as possible. Figure 3-4. Span Wire Installation Model 1010 Note: This method should only be used if other methods are not available. 13

14 3.1.1 Model 1010 Radio/GPS Unit Installation 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 (76 m). Screw a nipple (or pipe) into the base of the radio/gps unit. Do not tighten the locknuts yet. 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 3-5. 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 3-5.

15 1. 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 3-6. Leave approximately 4 inches (10 cm) of cable inside the cover and tighten the compression nut to secure the cable. 2. Strip approximately 3 inches (8 cm) 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. 3. Strip 1/4 in (6 mm) of insulation from each wire. NOTE: It is very important to not strip too much insulation, as it may lead to short circuits, or too little insulation, as it may prevent the wire from making good contact. 4. 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 3-1 also shows the terminal block pin number, wire color, and function of each wire. 5. The terminal block may be removed to allow easier connections. 6. Replace the wiring cover and tighten the screws. 7. Orient the radio/gps unit so that the cable retainer is facing an area from which vehicles will NOT be approaching. 8. Tighten the locknuts on the nipple/pipe to secure the radio/gps unit so it will not move. 9. Finish routing and securing the cable. Use cable ties as required. Keep the cable lower than the entry point or use a drip loop. Figure 3-6. Model 1010 Radio/GPS Cable Installation 1. Intersection radio/gps unit 5. Rubber bushing pin terminal block 6.

16 3.1.2 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. If any of the following conditions are present, the model 1012 is not recommended: Cabinet located under bridge, in another structure etc. Downtown areas Trees over the cabinet significantly obstructing the view of the sky Buildings close to the cabinet significantly obstructing the view of the sky View of approaches obstructed by buildings, signs etc. Nearby bridges blocking view of approach WAAS satellite/s not in view High speed roads that need maximum range Intersections with long ped clear, min greens etc. Pole mounted cabinets Where white colored dome on cabinet is not desired If pole mounted Model 1010 significantly improves performance Vandalism concerns 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. 16

17 Model 1050 Antenna mounting NOTES: 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. 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 (14 mm to 19 mm) 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 or 24 mm wrench. 5. Note: Do not over tighten the nut or the antenna may be damaged. 5 ft/lbs (73n/m) is the recommended torque. 6. Apply a sealant such as silicone RTV (not provided) around the antenna to provide a good seal with the antenna s built-in gasket. Figure 3-7. Mounting Model 1050 Radio/GPS Antenna on Cabinet Roof 1.

18 Radio mounting The Model 1012 radio may be placed on a shelf in the cabinet or it may be mounted using the included self-tapping screws Radio/GPS Unit Cable Terminations Figure 3-8. Mounting Model 1012 Radio/GPS Unit 1. Route the cables from the radio/gps antenna through the cabinet to the radio/gps unit location. Coil up any excess cable. NOTE: When coiling excess cable do not create any sharp bends in the cable or the cable may be damaged. 2. Connect the cable labeled GPS to the GPS connector on the radio/gps unit. Connect the other cable to the Radio connector. Tighten the connectors using a 5/16 inch wrench (an 8 mm wrench may also be used). 3. Plug the 15 pin connector of the radio/gps cable (black cable) into the P1 connector of the radio/gps unit and tighten the screws. 4. Route the cable to the location where the phase selector will be installed. 5. Skip to Section for details on connecting the radio/gps cable. NOTES: The connectors are keyed and cannot be connected to the wrong connector. To avoid damage to the equipment always connect the GPS and Radio connectors before connecting the radio/gps cable. Plug the cable into the phase selector last. The radio/gps unit is not watertight; therefore it must be mounted inside the cabinet compartment. Never operate the equipment with the antenna cables disconnected or the equipment may be damaged. 18

20 4 Powering the Phase Selector The phase selector operates on either 120VAC 60Hz or 24 VDC. The phase selector then powers the rest of the Opticom intersection equipment. Powering the phase selector requires one of the following inputs: Pin A B L M N Input DC- DC+ (24 VDC) AC Ground AC Neutral (AC-) AC Hot (AC+) Table 4-1 Phase Selector Power Input If the phase selector detects both 24 VDC and 120 VAC, it will use 120 VAC See figure 5-20 for locations of pins A, B, L, M, N Current Draw: When powered by 120VAC 60Hz, the Model 764 phase selector current draw is 80 ma o Add 100 ma for the radio/gps unit o Add 15 ma for each 711 detector o Add 30 ma for each 721or 722 detector o Add 15 ma for the 768 AIP When powered by 24 VDC, the Model 764 phase selector current draw is 110 ma o Add 500 ma for the radio/gps unit o Add 15 ma for each 711 detector o Add 30 ma for each 721or 722 detector o Add 40 ma for the 768 AIP 4.1 Powering on 120 VAC 60 Hz Plug the phase selector into a card rack or slot that will provide 120 VAC on pins M and N. Voltage range is VAC 57-63Hz. 4.2 Powering on 24VDC Plug the phase selector into a card rack or slot that will provide 24 VDC on pins A and B. Voltage range is VDC. It is also possible to power the phase selector on 24 VDC by providing power through the front DC connector. This connector is only used to provide power if neither 120 VAC nor 24 VDC is available on the card edge connector. The label on the removable 24 VDC connector shows the proper polarity. This connector is an input only it does not provide a 24VDC output. 20

21 5 Phase Selector Installation in Controller Cabinets with Existing Card Racks CA/NY Type 170 (33X) controller cabinets and some NEMA cabinets have input files that will accept one or two phase selectors. Power input and preemption output wiring is factory installed in the cabinet for the phase selector. Power is provided for the phase selector at 120 VAC. Some cabinets may provide both 120 VAC and 24 VDC. In this case the phase selector will use 120 VAC. 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. In 170/33X cabinets, two input file slots are dedicated for use by 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. 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. Additional outputs are available on the model 768 auxiliary interface panel. See section 9-5 for details on the additional outputs if needed. Install the phase selector into slot J13 of the lower input file, making sure it is fully seated. See Figure

23 5.1 Potential for Electrical Shock A potential exists for a low-current electrical shock (less than 4.5 ma) caused by leakage current in the power supply section of the phase selectors. You may experience this low-current shock when you touch the front of the phase selector, when you insert the phase selector into its slot in the input file, or when you remove the phase selector from its slot. You can minimize this shock potential by making sure that pin L of the card edge connector in the 170 type controller input file is grounded properly to earth ground. If pin L is not connected to earth ground, your risk of exposure to this shock potential increases. Use the following procedure to verify that pin L is connected properly to earth ground. WARNING This procedure may expose you to AC voltage and the risk of electric shock or electrocution. Turn off the AC mains and use accepted and recognized safety precautions to avoid exposure to the risk of electric shock or electrocution. Electric shock may cause severe injury or death. 1. Turn off AC power to the input file. CAUTION This procedure must be performed in an Electro-Static Discharge (ESD) free environment. Failure to perform this procedure in the proper environment may damage the equipment. 2. Remove the phase selector from the input file slot and place it in a static-free bag. Do this for all phase selectors in your system. 3. Locate pin L on the 44-pin edge connector of each phase selector slot and verify continuity to earth ground. See Figure 5-1. a) Set an ohmmeter to its lowest resistance scale. b) Measure the resistance between pin L and earth ground. If the resistance is less than 5 ohms, pin L is grounded properly. 4. If the resistance is greater than 5 ohms, inspect the input file wiring and repair and/or replace as necessary to correct the problem. Then retest the resistance. 23

24 6 Phase Selector Installation in NEMA Cabinets using 760 or 1040 Card Rack If you will be using the phase selector in GPS only mode a Model 760 or 1040 card rack may be used. If you are using the phase selector in IR or IR/GPS simultaneous mode a Model 760 card rack should be used. Model 1040 card racks have no connection points for IR detectors. NEMA controllers usually require a card rack. The phase selector plugs directly into the card rack which then sits on a shelf in the traffic controller cabinet. The card slot in the Card Rack is intended to be used with a single phase selector. The edge connector is wired to connector J1 on the card rack front panel, which is connected (through the 9-pin harness) to the traffic controller. The card rack harness is connected to 120 VAC to power the phase selector. The preempt outputs are then wired to the appropriate preemption input terminal in the controller cabinet. See the cabinet drawing to determine the proper location. The phase selector supplies four outputs to the traffic controller. Additional outputs are available on the model 768 auxiliary interface panel. See section 9-5 for details on the additional outputs if needed. 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. 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. WARNING This procedure may expose you to AC voltage and the risk of electric shock or electrocution. Turn off the AC mains and use accepted and recognized safety precautions to avoid exposure to the risk of electric shock or electrocution. Electric shock may cause severe injury or death. 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. 24

25 1. Place the card rack at the desired location in the controller cabinet. 2. Install the phase selector into the card rack making sure it is fully seated. See Figure Route the 9-pin harness wires to their terminals. 4. Strip 1/4-inch (6 mm) of insulation from each wire to be used. 5. Install a spade lug on each wire and connect it to the appropriate terminal. See Figure 5-18 and Table Locate the controller terminals for AC+, AC, chassis ground, and connect these wires. 7. Power input range: 89 to 135 VAC, 60 Hz. 8. Connect the AC wires after the circuit breaker and surge suppression devices. 9. Connect the logic ground wire to a logic ground/logic common terminal. 10. Connect the priority output wires to the appropriate preempt inputs. 11. Connect plug P1 of the 9-pin harness to connector J1 on the card rack front panel.

27 6.1 Model 1045B Card Rack The Model 1045B card rack may be used in GPS only operation. The Model 1045B contains a universal power supply that provides 24 VDC to power the phase selector. The 9-pin harness for the model 1045 card rack is identical to the 9-pin harness for the model 760 card rack. See the previous section for installation details. Model 1045B power input: VAC Hz NOTE: Model 1045A power input: VAC, Hz Model 1045 in IR Operation If you will be operating in IR only mode or simultaneous IR/GPS mode it is recommended that a model 760 card rack be used. There is no terminal strip on a model 1045 card rack for connecting IR detectors. However IR detectors may be connected using an auxiliary interface panel. See the detector installation manual for details. 27

28 7 Model 755 Four Channel Adapter Card and Other Model Card Racks If you are using your Model 764 phase selector in an existing model 360 or 560 system chassis or a NEMA type card rack that is wired for two, two-channel phase selector, you will need to use a model 755 fourchannel adapter card. The Model 360 and 560 system chassis have slots for two, two-channel phase selectors. The channel 1 and 2 IR detector inputs and preemption outputs are wired to one of these slots, and the channel 3 and 4 IR detector inputs and preemption outputs are wired to the other slot. The Model 755 four-channel adapter card is needed to connect the channel 1 and 2 detector inputs and preemption outputs to the four channel phase selector. 1.

36 9.3.2 Confirmation Light Wiring with Electromechanical Relay Interface This section describes confirmation light using customer supplied relays. The following is recommended specifications for the electromechanical relay: Use a 24 VDC relay with a coil impedance of approximately 1000 ohms. The maximum amount of current that the phase selector output is designed for is 50 ma. The relay should have a diode across the coil, Use a 1N4004 or equivalent diode. The following relay manufactured by IDEC meets the above listed requirements: Relay: RH1B-UD-DC24V Socket: SH1B-05 This relay contains a diode, so the diode shown in Figure C-1 is not needed. This relay is available from Newark Electronics and other electronics supply houses. NOTE: For applications with frequent activations, it is recommended that a solid-state relay be used in place of an electro-mechanical relay. A load switch would be another option. Omron G3NA-205B-DC5-24 This relay is available from Digikey (p/n Z165-ND) and other electronics supply houses. WARNING This procedure may expose you to AC voltage and the risk of electric shock or electrocution. Turn off the AC mains and use accepted and recognized safety precautions to avoid exposure to the risk of electric shock or electrocution. Electric shock may cause severe injury or death. 1. Locate and identify the input connections in the traffic control cabinet for each electromechanical relay that switches power to the confirmation lights. 2. Place a diode (1N4004 or equivalent) across the input to each electromechanical relay to prevent damage to the Phase Selector. See Figure Determine the appropriate length of wire required to connect the auxiliary interface panel to the wiring points for the relays. 4. Wire gauges from 22 to 16 AWG may be used. 5. Strip 1/4-inch (6 mm) of insulation from both ends of the wire being used. 6. Insert one end of the wire into the desired terminal of the auxiliary interface panel and tighten the screw.

38 9.4 Connecting existing harnesses to the model 768 auxiliary interface panel If you are upgrading from a previous generation of Opticom equipment and the current installation has an auxiliary interface panel or auxiliary harness/green sense harness you may be able to plug the existing harness/cable into the model 768 auxiliary interface panel so that rewiring may not be necessary. Not all functions will be available; in some cases it will be necessary to move wires from the existing model auxiliary interface panel to the new 768 auxiliary interface panel. In those cases it is recommend that the existing auxiliary panel be removed and all wires moved over to the 768). Leave connector cover in place on J4 if not being used Existing GPS installation using model 1035 auxiliary harness You may plug the 44 pin connector from the model 1035 into the 44pin connector on the 768. No rewiring is needed to use current green sense connections. See Figure Existing GPS installation using model 1030 auxiliary interface panel You may plug the 44 pin connector from the model 1035 into the 44pin connector on the 768. However, this is only possible if you are only using the model 1030 for only green sense connections. See Figure 9-5. If you are using the model 1030 for additional functions such as additional outputs, time sync or COM, it is necessary to remove those connections from the 1030 and connect them to the 768. In this case, it is recommended that the 1030 panel be completely removed and all connections be moved to the Existing IR installation using a model 757 auxiliary harness You may plug the 44 pin connector from the model 757 into the 44pin connector on the 768. No rewiring is needed to use current green sense and auxiliary detector connections. See Figure Existing IR installation using a model 758 auxiliary interface panel You may plug the 44 pin connector from the model 758 into the 44pin connector on the 768. No rewiring is needed to use current green sense, auxiliary detector and confirmation light connections. See Figure 9-5. If you are using the model 758 for additional functions such as separate output for high and low priority output, it is necessary to remove those connections from the 758 and connect them to the 768. In this case it is recommended that the 1030 panel be completely removed and all connections be moved to the 768. If you are using the model 758 for additional functions such as manual control enable, the model 764 phase selector does not currently support this function. It is recommended that a model 752N/754N continue to be used in this intersection. 38
