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

This European Standard 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. This European Standard • 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, • does not cover communication protocols and application procedures, • does not treat system aspects that influence the AGL operation. NOTE These units may be used forming part of either a SMGCS or A-SMGCS to guide and/or control the surface movement of aircraft by means of visual aids.

Elektrische Anlagen für Beleuchtung und Befeuerung von Flugplätzen - Technische Anforderungen für Steuer- und Überwachungssysteme von Flugplatzbefeuerungsanlagen - Geräte für selektives Schalten und Überwachen individueller Feuer

Diese Europäische Norm soll allgemeine Mindestgrundanforderungen für Einheiten festlegen, die unabhängig von der für das Schalten und/oder Überwachen von einzelnen oder einer Gruppe von Lampen in Reihenstromkreisen von Luftfahrtbodenfeuern eingesetzten Technik sind. Diese Europäische Norm • gilt für die Einheiten, die elektrisch direkt mit der Primär- oder Sekundärseite eines Luftfahrtbodenfeuer-Reihenstromkreises verbunden sind und die dazu benötigt werden, das selektive Schalten und/oder Überwachen von Lampen zu übernehmen, • beinhaltet keine Übertragungsprotokolle und keine Anwendungsverfahren, • behandelt keine Gesichtspunkte des Systems, die den Betrieb der Luftfahrtbodenfeuer beeinflussen. ANMERKUNG Diese Einheiten dürfen als Teil einer SMGCS oder einer A-SMGCS eingesetzt werden, um die Bewegung von Flugzeugen auf der Piste mit Sichthilfe zu leiten und/oder zu überwachen.

La présente Norme Européenne est destinée à fournir un cadre minimum d’exigences générales, indépendantes des technologies utilisées, aux modules utilisés pour la commutation et/ou la surveillance des lampes individuelles ou des groupes de lampes dans les circuits de balisage AGL (Aeronautical Ground Lighting). Cette Norme Européenne • s’applique aux modules directement reliées électriquement au primaire ou au secondaire d’un circuit série AGL et qui sont nécessaires à la commutation sélective et/ou à la surveillance des lampes, • n’englobe pas les protocoles de communication et les procédures d’application, • ne traite pas des aspects systèmes qui influent sur le fonctionnement du balisage AGL. NOTE Ces modules peuvent être utilisés dans le cadre d’un système SMGCS ou A-SMGCS pour guider et/ou surveiller la circulation de surface des aéronefs par le moyen des aides visuelles.

Introduction
Aeronautical Ground Lighting (AGL) at an aerodrome provides the pilots of aircraft and drivers of
vehicles moving on the aerodrome surface, with guidance information. Selective switching and
individual lamp monitoring is one way of controlling the AGL to achieve this.
1 Scope
This European Standard 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.
This European Standard
• 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,
• does not cover communication protocols and application procedures,
• does not treat system aspects that influence the AGL operation.
NOTE These units may be used forming part of either a SMGCS or A-SMGCS to guide and/or control the surface
movement of aircraft by means of visual aids.

can be expected, the unit shall be designed as intended for underground use. See 4.3.
4.7 Reliability
The MTBF of the unit shall be published in the manufacturer’s technical data.
