2.3 Installation

In-pavement fixtures must be installed according to the plans and specifications; the

applicable regulatory guidance; and the manufacturer’s instruction manual. For FAA

applications, installation guidance is provided in AC 150/5340-30 (current edition).

Following are a number of items to be aware of:

2.3.1 Mechanical

Requirements

1. Correct dimensional placement of the lights is of prime importance. To achieve this,

careful attention to detail is required. Survey instruments may be used to accurately

position all fixtures for their precise location, elevation, and azimuth. The tolerances

required in FAA AC 150/5340-30, and the plans, must not be exceeded. The light beam

must be aligned as described in FAA AC 150/5340-30 with a horizontal tolerance of ±1

degree. The light fixture must be level, and the top outside edge of the fixture must be

between +0 inch and -1/16 inch (1.5875 mm) with respect to the surrounding pavement.

See FAA AC 150/5340-30, Chapter 11, Fixture Mounting Bases, for additional guidance

on installing Light Bases. Incorrect installation may cause the light output to appear to be

too dim or too bright. Incorrect installation may also increase the risk for fixture

mechanical failures.

2. Insure all base can mounting surfaces are free of dust, dirt or debris.

3. Per FAA AC 150/5340-30, Chapter 10, and FAA Engineering Brief No 83, the fixture must

be mounted using properly installed anti-vibration lock washers under the mounting bolts.

An anti-vibration lock washer is composed of a pair of unique washers with radial teeth

that grip and seat the mating surfaces. The rise of the cams between the face of washers

is greater than the pitch of the bolt. This creates tension that positively locks the bolt. Use

extreme care when placing the two halves of the lock washer together. The cams (or

steps) of each half of the lock washer must face each other.

4. Per FAA AC 150/5340-30, Chapter 10, and FAA Engineering Brief No 83, it is extremely

important that other types of washers, such as split washers, must not

be used. Failure to

use properly installed anti-vibration lock washers will cause mounting bolts to become

loose. Loose bolts increase the risk for fixture mechanical failures. Loose bolts can also

increase fixture slippage which increases the shear load on the bolts. This can cause

individual bolt failure, resulting in increased load on the remaining bolts. Finally, this can

result in an increased risk that bolts come out or shear-off, causing the bolt and fixture to

become FOD on the Runway or Taxiway.

5. Consider the use of ceramic bolts, especially if stainless steel Light Bases are being used.

Guidance on the application of ceramic bolts is given in FAA Engineering Brief No 83.

6. The fixture hold down bolts must be torqued properly and must not be over torqued.

Recommended torque values are given in “Installation on L-868 Base” on page 16. If the

torque limit is exceeded (typically due to the use of impact wrenches), the bolt is

WARNING

Read installation instructions in their entirety before starting installation.

• Become familiar with the general safety instructions in this section of the

manual before installing, operating, maintaining or repairing this

equipment.

• Read and carefully follow the instructions throughout this manual for

performing specific tasks and working with specific equipment.

Failure to follow these warnings may result in serious injury or

equipment damage.

overstressed and is on its way to failure. After corrosion occurs, removal can cause the

head to snap off. The head can then become FOD.

2.3.2 Electrical

Requirements

1. One of the most common causes of water leakage within in-pavement fixtures is a

pinched cord-set. It is commonly caused by trapping the fixture wires when the fixture is

installed on the base can. Use caution when mounting the fixture on the base can to

prevent the incoming wires from becoming pinched.

2. If the wire conductor jacket is compromised, the entire cord-set must be replaced.

3. Never use electrical tape to repair the cord-set, since taping will not adequately seal the

wire conductor jacket adequately to prevent water leakage.

4. Never pick the fixture up using the electrical connection leads. Picking the fixture up by

the leads can cause a break in the wire conductor jacket. If the wire conductor jacket is

cut, water is drawn in during the On and Off periods due to thermal cycling of the fixture.

5. Insure that the primary isolation transformer connection splicing methods as shown in

FAA AC 150/5340-30 are followed. It is also recommended that heat shrink be used on

each primary isolation transformer connection to minimize the risk of overall series circuit

insulation resistance degradation.

6. Verify the correct current levels are coming into the fixture. Measure the fixture input

current on a sample of fixtures using a True RMS ammeter. If current is not correct at

each CCR step:

a. Verify the primary isolation transformer current is correct at all steps. If the primary

current is incorrect, the CCR may need to be calibrated or repaired.

b. Incorrect primary isolation transformer current may also be caused by low overall

series circuit insulation resistance. Meg the series circuit and repair if necessary.

7. Verify each isolation transformer wattage matches the wattage indicated in the “Electrical

Supply ” on page 7.

8. Verify each isolation transformer ratio is correct. For a 6.6A CCR, the isolation

transformer must have a ratio of 6.6A/6.6A. For a 20A CCR, the isolation transformer

must have a ratio of 20A/6.6A.

2.3.3 Installing the Fixture This section provides installation instructions for the L852C-D and ICAO ITCF fixtures.

NOTE: Also see the following:

— “Installing a New Optical Unit” on page 28.

NOTE: Light Detail:

2.3.3.1 Overview of Sequence

of Work

1. Electrical contractor locates new light bases and interconnecting conduit trench, and

excavates for light base bottom section by saw cutting or core drilling. Electrical contractor

prepares subgrade and stone subbase, sets bottom section with rebar, rigid steel conduit

stubs and drain, and pours high early strength concrete-encasement excavation.

Electrical contractor shall record can locations and elevations of mud plate after concrete-

encasement.

Electrical contractor excavates conduit trench, installs rigid steel and fittings, backfills

conduit trench with high early strength concrete.

2. General contractor prepares and installs concrete pavement. Electrical contractor makes

a pilot core to find mud plate center point indent before final core-drilling.

3. Electrical contractor core-drills concrete pavement. Electrical contractor installs top

section, y-flange ring, space and lighting fixture, and pours epoxy joint sealer. Provide

space for adjustment with spacers, maximum number of spacers shall be 3.

4. Se specific details as shown in FAA AC 150/5340-30 (current edition).

1. Light bases shall be installed with care to assure vertical & azimuth alignment of

fixture.

2. Provide 2'-3' cable slack within light base to allow transformer servicing.

3. Bolts and washers used during installation of base, cable and transformers shall
