If a fault occurs during the 30 -day test period correct the problem and restart the test. Once the 30 -day period has expired with no recordable system faults and meets the approval of the Representative the system will be considered for final acceptance. Connect the conflict monitor or malfunction management unit to function as specified in Section 952.2(c). When the controller assembly becomes operational, and during initial turn-on, demonstrate that the conflict monitor or malfunction management unit will cause transfer of the signals to flashing operation upon sensing all possible conflicting signal indications. Conduct the demonstration, as directed, in the presence of the Representative. The 30 -day system test must not begin until the conflict moni tor or malfunction management unit is functioning properly. Before or during the initial turn-on, connect output from shutdown relay to the output and power input of the signal load switches. Connect relay to controller assembly to provide flashing operation with the traffic signal controller unit installed or removed. Provide activation of the shutdown relay from any of the following sources:

• Removal of controller voltage, when indicated

• Police panel switch

• Output from conflict monitor or Malfunction Management Unit

• Provide cabinet documentation and labeling as follows:

For signal controller, fiber optic cable, sensor devices, ITS, communications, connected vehicle, and any additional components provide interconnection diagram showing cable and port connections. Label all components and cables using the ANSI/TIA-606-B standard as a guideline and the following:

• Label each component with an identifier that corresponds to the interconnection diagram.

• Label cables at both ends. Provide information on each cable end to indicate the near and far end connections.

• The cable end with the label is considered the near end; the opposite cable end is considered the far end.

• Label all detector lead -ins as per the PennDOT Automated Traffic Signal Performance Measures

• Label text:

ͦ Indicate the near end component identifier and port connection on the first line. ͦ Indicate the far end component identifier and port connection on the second line. ͦ Indicate the system or network title on the third line. ͦ Abbreviations are acceptable if they are consistent between the interconnection diagram and the component identifier.

• Submit for approval any adjustments or modifications to labeling convention.

• Install the IP-addressable power strip in the rear rack. Plug the following auxiliary devices into the IP-addressable outlets and other components as directed:

ͦ Communications equipment (e.g. Ethernet switch, cell modem, router/firewall, etc.) ͦ Detection equipment (e.g. video, radar)

ͦ Adaptive system processor

• Install test button panel in the front rack.

• Operate SDLC Port 1 on Serial Bus #2 as needed.

• Provide and program a spring-loaded door switch in the upper right corner of the cabinet opening for use as a “door open” alarm. If the controller cabinet is connected to an RTMC or central system, the “door open” alarm must place a notification to the RTMC or central system.

• Provide a spare SIU and a spare high-density switch pack.

• Tether USB drive to a shelf or other permanent piece of the cabinet.

Record the existing timing of each controller. Make two copies placing one in the controller cabinet while retaining the other. The record consists of a copy of the timing and phasing diagram and includes the date, the change made, the name of the person authorizing the change, and the name of the person making the change. Before making a timing change, check the existing timing settings and verify that they are as indicated on the most recent record. Notify the Representative if unauthorized timing changes have been made. Provide a copy of each change of record.

controller cabinet using a waterproof sealant. Install the time clock base unit (if needed) in the controller cabinet and c onnect to input/output terminals to the controller according to the manufacturer’s recommendations. Connect to the equipment safety ground. Program the controller as needed to receive the GPS signal and reset the controller clock a minimum of once per day. Field test for indicated operation.

is wired for the maximum phase capability of the controller unit.

coded controller terminals as directed by the Representative. Crimp-type connectors are not to be used for traffic control cable or interconnection cable. All wiring and cable connections are to be neat and with all such cables tie-wrapped. Spare conductors of signal cable and interconnection cable are to be neatly wrapped in the cabinet and of the same length as the active conductors. Connect all communication cable conductors to the terminal block. Mount on the inside of the lower left cabinet wall a communication cable terminal block. The terminal block is to have a sufficient number of connections to splice two 12-pair communication cables together. If applicable, mount on this panel an RS-232 interface for connecting a portable PC to the 2070 Microcomputer. The RS-232 interface is to consist of a shielded cable with a DB9 connector at one end, and a 2070 C2 type connector at the other. Plug the DB9 connector into the C2 port of the 2070 controller.

internal diameter conduit as specified in Section 954. Run a continuous conduit segment from the base of the pole, through the bottom entry hub of the junction box, and into entry hub in the bottom of the Controller Cabinet. Place conduit to maintain the minimum bend radius of fiber optic cable. The conduit from the cabinet to the closest junction box or manhole is incidental to this item. The cabinet is to have the means to hold service loops, each 20 feet in length, of each of the jacketed fiber optic cables entering and leaving the cabinet. Secure each service loop to the bottom of the lowest rack in the cabinet in such a way as to ensure the minimum bend radius of the cable(s ) and prevent interference of any kind. However, the service loops are to be easily removed and reattached during fiber maintenance. Carefully route the fiber optic cable(s) to the patch panel for termination. The cabinet is to have a patch panel as necessary, mounted on an easily removable aluminum panel, to house all internal fiber splices; mount the aluminum panel in an appropriate location inside the cabinet. Secure the fiber optic cable(s) to the panel before entering the patch panel. Terminate all field fibers in the

cabinet as specified in Section 953.3(i) . If applicable, mount on this panel an RS -232 interface for connecting a portable computer to the 2070 microcomputer. The RS-232 interface is to consist of a shielded cable with DB9 connect at one end, and a 2070 C2 type connector at the other. Mount the DB9 connector on the panel for easy access, and the C2 type connector plugged into the C2 port of the 2070 controller.
