BS EN 50490:2008 Electrical installations for lighting and beaconing of aerodromes. Technical requirements for aeronautical ground lighting control and monitoring systems. Units for selective switching and monitoring of individual lamps
BS EN 50490 is intended to give general minimum frame requirements for units that are independent of the technology used for switching and/or monitoring of individual or group of lamps in an AGL series circuit.
BS EN 50490 applies to the units that are directly electrically connected to the primary or secondary side of an AGL series circuit and are needed to provide the selective switching and/or monitoring of lamps. It does not cover communication protocols and application procedures. It does no cover system aspects that influence the AGL operation.
