ADB’s Airfield Lighting Control System (ALCS) family ranges from Style 1 to
Style 7, enabling selection and specific adaptation of Airfield Ground Lighting
(AGL) control features for all sizes and levels of complexity of airfield ground
lighting systems.
Application of ALCS Style 2 and 3
Airfield Lighting Control Systems from ADB enable the air traffic controller
to operate the entire lighting system via easy-to-use touch screen monitors.
Operational features, system status and fault messages are clearly visualized
in well structured masks on the controller HMI in the tower and maintenance
HMI in the substation. While the controller work station is focused on the
operational status of airfield ground lights, the maintenance station monitors
the actual status and error messages of the electrical components, constant
current regulators and system interfaces.
ALCS Style 2 and 3 are state of the art systems for easy and straight forward
control and monitoring of visual aids, tailored to the needs of airports with
one or two runways and maximum 32 (Style 2) or 56 (Style 3) airfield lighting
circuits (typical: approach, threshold until end of runway, PAPI, taxiways and
stopbars).
ALCS Style 2 is used for airports with one (1) airfield lighting substation, while
Style 3 is used for airports with two (2) substations to power the visual aids.
ALCS Style 2 and 3 feature a serial RS 485 Jbus communication interface
(2A, 3A) or a multiwire cable connection (2B, 3B) to constant current
regulators (CCR) and serve up to 10 digital I/O’s per substation.
Both versions of the system have a modular design in hardware and
software, allowing extensions by adding additional user interfaces in AGL
substations. This facilitates modifications for future airport growth and
upgrades.
