Wanco® X-Marker™ L-893(L) Runway Closure Marker (Model WTRC)

 The Wanco X-Marker L-893(L) is ETL-certified to meet FAA AC 150/5345-55, “Specification for L-893, Lighted Visual Aid To Indicate Temporary Runway Closure” and FAA EB67, “Light Sources Other Than Incandescent and Xenon....” Based on proven Wanco generator technology, the X-Marker L-893(L) features the lowest fuel consumption and longest run-time in the industry. Its flasher control system ensures the high-efficiency LED lights operate consistently at the FAA required flash rate. The X-Marker L-893(L) is deployable by a single person in less than five minutes. Operation In standard operating modes, the giant “×” shape signals approaching aircraft at a rate of 2.5 seconds on/2.5 seconds off with aviation white LEDs, per FAA requirements. The system’s “fail-on” circuit turns all lights on continuously in the event of a controller malfunction. Amber LED operation indicators are visible on the backs of all four arms. Two standard operating modes include full brightness for daytime operation and automatic dimming for day/night operation. High-power mode applies maximum continuous power to all lights, increasing their temperature for melting snow and ice accumulation on the light fixtures. The system operates on engine power from 0 to 140°F (–18 to 60°C). Coldweather options extend the low operating range down to –40°F (–40°C). Construction The X-Marker × shape consists of four arms of steel square tubing protected by aviation yellow powder coating for high visibility and durability. Each arm includes an aluminum enhanced-visibility panel. Each LED fixture housing is a robust, weatherproof, cast aluminum heat sink. Performance is unaffected by wind speeds in excess of FAA requirements. Power The battery-operated, generator-assisted system consumes just 0.18 gallons (0.681 liters) per hour, which provides up to a week of operation before refueling. Battery power provides up to 24 hours additional run time after fuel supply is exhausted. The system can operate on 120/240VAC shore power with the engine switched off, at temperatures from –40 to 140°F (–40 to 60°C).
