BARRIER TRANSFER MACHINE GUIDE WIRE DESCRIPTION:

The guide wire installed in the form of a loop will help guide the moveable barrier machine. This "loop" consists of a saw cut (about 2" in depth) in the center of each of the two center lanes. Number 14 wire is placed (along with a spare) in each cut.

This guide wire is run in approximately 1/4 mile increments and loops back on itself in the opposing . A frequency generator is attached to the ends of each loop forming a radiating antenna. The Barrier Transfer Machine (BTM) then senses the generated signal and uses it to center the machine, and hence place the barrier directly on the lane line.

The 1/4 mile loops are run the entire length of the facility. Ultimately, they will extend from SR-163 to approximately the Via Rancho Pkwy OC.

BARRIER TRANSFER MACHINE BARRIER SYSTEMS, INC. TECHNICAL BRIEF: INSTALLATION OF AUTOGUIDANCE WIRE AND RELATED EQUIPMENT

N-7 TB 951130-Rev. 2 Page 1 of 7

INSTALLATION OF AUTOGUIDANCE WIRE AND RELATED EQUIPMENT

1. INTRODUCTION This specification covers the installation of the guidance wire and related equipment to provide a radio guidance signal to the barrier transfer machine. The guidance wire system consists principally of one or more grooves in the roadway as shown on the plans which are cut to a depth between 1" to 3" as specified on the plans. A guidance wire and a backup guidance wire, both 14 AWG encased in a loose fitting, polyethylene tube are placed in these grooves. The wires are embedded in an approved sealant and are run from a signal generator box to the groove(s) in the roadway and then returned to the signal generator box in a more or less parallel path as shown on the plans, no closer than 3-feet from the nearest guidance wire in the roadbed. Power is provided to the signal generator boxes (120 volt AC 20 amp).

2. WIRE LOCATION The primary length of wire is located in one or more grooves in the roadway as shown in the plans. The maximum wire length from the signal generator to the road and back to the signal generator is 1/2 mile. Schematic representations are shown in Figures 1, 2 and 3. The grooves must be cut parallel within +/- 1/4" of the specified location and each other. At various locations on the plans, tapers of up to 1-foot in a hundred may be specified between each wire. Tolerance from the theoretical taper line must be held within +/-1/4" as well. At various locations it may be necessary to cut grooves more or less perpendicular to the guidance wires to go around obstacles, to provide for loops at bridge joints and/or to get to connection boxes located out of the roadway. These cuts must be perpendicular to the principal guidance wires within +/- 5 degrees to avoid erroneous guidance signals to the barrier transfer machine. Groove depth and width and typical corner details for the groves shall be as specified on the plans, representative examples are shown in Figure 4.

At each , the wires are to be looped under the joint with a minimum radius of 12", to allow for expansion and contraction. These shall be encased in a suitable flexible conduit. This is shown schematically in Figure 5. Details shall be as specified in the plans.

3. LOOP WIRE The guidance loop wire shall be 14 AWG per Attachment of TB 951127.

4. LOOP WIRE SEALANT The wire sealant used shall meet the requirements of TB 951128 or shall be an approved equal.

5. SIGNAL GENERATOR BOXES Signal generator boxes shall be provided with 120 volt AC power (20 amps) and shall have provisions for mounting a signal generator panel containing 4 signal generator boards. The size of the panels will be 13" by 21". These panels shall be mounted on 1- inch stand-offs from the surface of the signal generator box so as to assist cooling. In addition to all requirements specified in TB 951129, a top mounted green light (weatherproof and approved) clearly visible from a distance of 1/10 mile at night shall be provided to indicate that power is available to the box. The light shall be mounted so as to provide an unobstructed view from the roadway from all viewing heights between 30" to 120" above the roadway. Signal generator boxes shall be as per specification, TB 951129 and shall be pole or frame mounted as specified on the plans. Locations shall be as specified on the plans.

6. JUNCTION BOXES All splices shall be made in an approved junction box located out of the main area. Junction boxes shall be located as specified in the plans.

7. CONSTRUCTION METHODS Installation of the cable shall be in accordance with the plans and with the national electrical code. No splices shall be made in the loop which would increase the electrical resistance of the circuit. Splices shall be made only in pull boxes and shall be soldered using no-corrosive solder. Splices shall be insulated using thermosetting compound, heavy duty heat shrinkable tubing with sealant, or heavy duty heat shrinkable tape with sealant approved for outdoor use. A service loop shall be provided in each pull box.

After installation and prior to connection, all or part of the system may be tested at the engineer's option. Cable testing less than 50 megohms insulation resistance (from conductor to drain wire or conductor to conductor) at 500 volts shall be replaced.

8. MASTER SPECIFICATION For additional documentation of guidance system details, see TB 940721, “Barrier Transfer Machine Autoguidance System Wire and Loops.” This is a typical specification only. The applicable state engineer should review/approve all final documents before issue.
