Installation of the L861(L) Medium Intensity Elevated Edge Light

 

Mounting the Fixture

• The ALC-861L Elevated LED fixtures mount to a 1½” – 12 NF base plate or can be specially ordered to mount on a 2” NPS baseplate.
• The fixture ships from Airport Lighting Company ready to be plugged into an appropriate L830 Style isolation transformer with a 6.6amp output.
• Snake the cord through the column and frangible coupling, then plug the fixture into the isolation transformer secondary.
• Thread the frangible coupling onto the baseplate.
• Secure the column to the frangible coupling.

Bi-Directional Fixture Alignment

• The ALC-861L bi-directional fixtures are assembled so that the 2 clasps that hold through the glass lens are on the dividing line of the bi-directional colors.
• Line the ALC-861L up so that a line thru the clasps is perpendicular to the runway and the colors are in the correct orientation.

Leveling the Fixture

• Place a torpedo level along the bottom edge of the light fixture base.
• Using the (3) ¼”-20 hex screws in the base of the fixture adjust the screws until the light fixture is level and tighten to 30 in-lbs.

Final Preparation and Verification

• Wipe the lens clean.
• Power the constant current regulator and check that the LEDs come on.
• Run through all the steps of the regulator and make sure that the light intensity increases as the current is increased.
• The fixture is ready to provide years of quality service.

Wiring Without an Arctic Kit

• The ALC-861L fixture leaves the factory ready to be connected to a 6.6A output isolation transformer.
• The secondary of the isolation transformer plugs into the fixture power cord.
• The power cord connects to 2 tabs on the driver board with quick connect terminals.
• The driver board connects to the LED light engine with a 2-position inline connector.

Wiring With an Arctic Kit

• The ALC-861L fixture leaves the factory ready to be connected to a 6.6A output isolation transformer.
• The secondary of the isolation transformer plugs into the fixture power cord.
• The power cord connects to the driver board and arctic kit in series.
• The remaining arctic kit power lead plugs into the remaining tab on the driver board.
• The driver board connects to the LED light engine with a 2-position inline connector.
• The driver board connects to the arctic kit control circuit with a 3-position inline connector.
