1.0 Safety
It is not safe to work on a constant current power system when the power is on. Make sure
the power is off before installing a runway light fixture. A lock out, tag out, procedure
should be used. An additional safety measure is to test that the circuit is off by using a
clamp-on ammeter. By using a clamp-on ammeter, clamped over the primary cable of the
isolation transformer, the installer can confirm that the circuit being worked on is off by
verifying that no current is flowing thru the primary cable.
2.0 Description
The High Intensity LED Runway Lights are elevated bi-directional and uni-directional runway
lights. The High Intensity LED Runway Light operate on a 2.8 - 6.6 Amp series runway
circuit.
FAA, certified to Advisory Circular 150/5345-46 (Current Edition): This product line meets
the requirements for L862 and L862E

3.0 Installation
3.1 FAA References and Siting Requirements
The requirements for siting of high intensity runway edge lights are explained in FAA
advisory circular 150/5340-30J.
The L862E fixtures, bidirectional red/green and red/red, and unidirectional red or green will
come with red and/or green lens retainers to provide daytime recognition.
3.2 Installation
3.2.1 Tools Required for Installation.

3.2.2 Installation Precautions.
It is not safe to work on a constant current power system when the power is on. Make
sure the power is off before installing a light fixture. A Lock Out Tag Out procedure is
strongly recommended. An additional safety measure is to test circuit by using a clamp on
current meter. By clamping over the primary cable in the fixture can, the installer has
performed an additional safety check by checking the circuit they are working on is off. At
the vault make sure the Constant Current Regulator powering the circuit is off and has been
tagged out. At the fixture, place a clamp-on ammeter over the primary cable and verify
that the current measures zero amps.
3.2.3 Proper Transformer.
It is recommended to use the specified transformer to power the L861SE (L). A smaller
transformer will not allow the fixture to work properly. An oversized transformer can be
used but will not work as efficiently. A 30/45-Watt isolation transformer is specified for all
fixtures referenced in this manual.
3.2.4 Pre-Assembly of Fixture.
Apply an anti-seize compound to the frangible coupling threads. Install frangible
coupling to the baseplate. Fasten the column to the fixture. Pass the L-823 plug thru the
frangible coupling and baseplate. Fasten the bottom of the column to the frangible
coupling.

9
3.2.5 Final Assembly.
Connect the secondary of the isolation transformer to the fixture. Apply anti-seize
compound to the 3 screws that will secure the secondary plug. Secure the secondary plug
to the baseplate with the 3 screws and plug retainer. Place the baseplate gasket in position.
Position the baseplate over the can so that the arrows on the fixture point towards the
runway centerline. Secure the baseplate to the can.
3.3 Aim Fixture
The arrows on the fixture cap should be pointed towards the runway centerline. The
shorter cross on top of the cap is used to sight the fixture for alignment with the row of
edge lights, the longer member of the cross can be used to align with the threshold lights.
Figure 4: Fixture Aiming.

10
3.4 Level Fixture
Place a level on top of the cap and level the fixture. If a torpedo level is used, level in both
directions of the cross. A bull’s eye level can be used at the cross intersection.

Figure 6: Leveling, Side View.

3.5 Torque Bolts
Once the fixture has been aimed and leveled, torque the ¼-20 fasteners to 64 inch-pounds
(5.3 foot-pounds). Recheck the level of the fixture.

4.0 Operation
The ESEL LED product line is designed to work on a constant current electrical supply that
delivers current from 2.8 amps to 6.6 amps. The fixture measures the input current and
automatically adjusts the light intensity. The fixture contains an input power board, a
controller, and light engine(s). The fixture senses which color will be emitted by the light
engine and adjusts its power accordingly. Change of light engine to a different color
requires no user adjustments.
Inspect that the fixture is properly installed and connected to the correct isolation
transformer. Turn on the fixture and the LEDS come on. Step the current level and the light
intensity will adjust to the correct intensity. When stepping current, allow a few seconds
for the intensity to readjust.
4.1 Plug and Know LED Circuit
The ESEL light engines use a 6-pin connector. 2 of the 6 pins provide power to the LEDs.
The remaining 4 pins are used to identify the light engine. When a light engine is connected
to the fixture, the fixture knows which light engine has been connected. This allows the
circuit to properly drive each light engine to its correct intensity.
4.2 Multiple Light Devices
The green light engine is made up of multiple LEDS. FAA requires the light engine to shut
off if 25% of the LEDs fail. The circuit is constantly looking at the LEDs. When 25% or more
fail, the circuit will power down within 2 minutes and a minute later it will shut the green
light engine off. If the fixture is off, do not touch the fixture. There is still power going to
the fixture. If a fixture appears to be off, cycle the power off and on. Observe the light
engines. Replace the light engine that does not have all the LEDs working. The red light
engine uses a single LED and does not adhere to the Multiple Light Devices rule. If the red
is off, the LED has failed, the fixture has failed or the red light engine has become
disconnected

13
5.0 Maintenance
5.1 Daily Maintenance
Check that all lights are working. Check that all lights have similar light output. Check that
the lenses are clean.
5.2 Monthly Maintenance
Check that all fixtures are aimed properly. Check that all fixtures are level on 2 axes. Check
that the fixture is secure, and all fasteners are tight. Check that all LEDs are illuminated.
Clean the lenses.

14
6.0 Trouble Shooting
6.1 Tech Support
Outside of aiming, leveling, and cleaning, the ESEL fixture should require very little
maintenance. The end user has the option to use this manual to perform advanced
maintenance, to call tech support at Airport Lighting Company at [phone] or to

6.3 Removing Electronic Parts.
When the light is out the cause can be in a few areas. The way to isolate the problem is to
start with a known good fixture. Test each part from the inoperable fixture in the known
good fixture, one at a time, until the problem is isolated. Then replace the defective part.
