Installation on L-868B Base

Type L-852A-D Dualite Bidirectional Taxiway Light Fixtures

Installation

(contd.)

Installation on Siemens Airfield Solutions Shallow Base

4.Turn on the power. Operate the light assembly for a minimum of five minutes. Turn off the power and allow the light assembly to cool.

5.Position the light assembly over the L-868B base and set onto the base. Align the light to the runway centerline. Make sure all spaces, shims, and gaskets are in place before installing light fixture on the base.

Remove the eyebolts and lifting rod.

6.Turn on the power to check that the lamp will illuminate. Operate for a minimum of five minutes.

CAUTION: The light assembly will be hot after this test. Allow time for assembly to cool before proceeding.

7.Apply one drop of Loctite AV to each of the six light assembly mounting bolts. Install the six bolts and lockwashers. Torque the bolts to 185 ±5 inch-pounds (20.902 ±0.565 Nt-M). Torque across the corners. Refer to Retorquing Mounting Bolts in the Maintenance section.

To install the L-852A-D dualite light fixture on a Siemens Airfield Solutions shallow base, perform the following procedure:

1.Splice the light assembly leads to AWG 16 wires with suitable pre- insulated connectors, crimped with the proper tool.

2.Train the leads and AWG 16 wires carefully so they run along the bottom of the sawed wireways.

NOTE: Small wads of plastic insulating tape may be used to wedge the leads and cables in the bottom of the wireways if necessary. Refer to Table 4 for the appropriate isolation transformer required for installation between the fixture and the series lighting circuit.

3.Make sure the O-ring is seated in the O-ring groove before bolting the fixture to the shallow base.

4.Lightly sand blast and clean with solvent all external surfaces that will be bonded into the runway, except for the wire entrance seal. This is done to make sure an adequate bond between the shallow base and sealer exists.

CAUTION: Do not handle the light fixture by the leads. This can break the waterproof seal and cause electrical leakage.

L-852A-D specifications

The Siemens L-852A-D is an advanced lighting system designed primarily for airport applications, providing a robust solution for runway edge lighting. This innovative product is engineered to enhance safety and operational efficiency in various weather conditions, catering to the unique demands of modern air traffic management.

One of the most notable features of the L-852A-D is its LED technology. The use of light-emitting diodes significantly increases energy efficiency compared to traditional incandescent lights. LEDs are known for their long lifespan, often exceeding 50,000 hours, which translates to reduced maintenance costs and less frequent replacements. This is particularly beneficial in airport environments where minimizing downtime is crucial.

The L-852A-D is designed to provide exceptional visibility with its high-intensity output, crucial for both day and night operations. The system's optical design ensures uniform light distribution, which enhances pilot awareness and improves navigation during takeoff and landing. Additionally, the device is engineered to comply with international aviation standards, ensuring reliability and safety in all conditions.

Another key characteristic of the L-852A-D is its durability. The system is constructed to withstand harsh environmental conditions, including extreme temperatures, high winds, and moisture. Its housing is built from corrosion-resistant materials, ensuring longevity even in challenging climates. The product is also designed to be highly resilient to impacts, which is essential in high-traffic airport settings.

The L-852A-D incorporates sophisticated control technologies that enable adaptive lighting capabilities. This feature allows for automatic adjustments based on external conditions, such as visibility levels, significantly enhancing operational efficiency. Furthermore, it can be integrated with central control systems, allowing for seamless management and monitoring from a single point.

Safety is paramount in airport operations, and the L-852A-D includes features that enhance user and operational safety. Its low profile reduces the risk of physical hazards, while the integrated fail-safe mechanisms ensure continued operation in the event of a power failure.

In summary, the Siemens L-852A-D runway edge lighting system combines advanced LED technology, durability, and intelligent control features to provide an efficient and reliable solution for airport environments. Its main attributes include energy efficiency, long lifespan, compliance with regulatory standards, and robust construction, making it an ideal choice for enhancing safety and operational efficiency in aviation lighting.
