Compliance with standards ICAO Aerodrome Design Manual, part 5 IEC (CCR’s standard 61822) FAA (AC150/5345-5 - L847) Applications SCS series selectors are up-to-date circuits selectors designed to feed up to 6 airfield lighting loops from one constant current regulator. They are fitted with a simplified electronic enable to communicate with latest generation supervision systems, allowing a very fast and simple commissioning. Circuits can be alternate (only one circuit will be supplied at a time), or simultaneous (different circuit at the same time). Typical applications are : • Alternate...

GENERAL PRESENTATION SCS selector is a stand alone cabinet, fitted with four brackets for wall mounting purposes. A front door, with a key lock, grants internal access, in order ot ease installation and maintenance operations Power connection is provided inside the cabinet. Outside connectors are available for communication link with the remote control system. • Amount of ways : up to 6 • Dielectric strength : Depending on CCR rating, and according to standards IEC (2xUn + 2500 Vca) or FAA (5xUn). • Supply voltage : 230V / 400V. • Protection index : IP 21. • Dimensions : H 700 mm, W 500 mm,...

PROTECTIONS Upon request, the selector may be fitted with the following options: • Output lightning arrestors • Input lightning arrestors • Circuit breaker. INSTALLATION Design for wall mounting, the cabinet is fitted with four brackets, in order to ease its installation close to the related CCR.

SCS : User Interface PRESENTATION : The user interface is located on the front door, and enable either a local use or a remote control mode, displaying feedback through light signals. CONTROL In case of an alternate selector, a rotative switch is provided to select the active way or remote control operation. In case of a simultaneous selector, one switch per way is provided, as well as a local/remote switch. FEEDBACK A light signal is provided for every way status feedback, as well as CCR inrush current presence (optional feature). PARAMETER SETTING Some options may require some parameter...

INTERNAL CONNECTIONS Power supply as well as interlock and remote control multiwire connection is performed through a terminal block, located inside the cabinet. Through holes are provided to protect the cables. SERIAL LINK REMOTE CONTROL Connectors are available on the outside side panel, for communication connection to the remote control system. RJ45 connectors for Ethernet, SubD connectors for RS485/JBus AIRFIELD LIGHTING LOOP Airfield circuit connection is performed through screw terminals located at the inside bottom of the cabinet. Loop connection is identified through labels...

The Stand alone Circuit Selector is identified by a serialised ordering code which indicates its type and particularity. If needed, add all useful precision and options. Example : SCS-IEC-1-4S-10-50-400-B4-100 = SCS compliant to IEC, 6.6A, 4 simultaneous ways, 50Hz/400V for max. 10kVA CCRs, with lightning arrestors, multiwire remote control and Ethernet connection: S | C |S | - | I | E | C | - [7] - | 4 |S | - | 1 | 0 | - | 5 | 0 | Series SCS : SCS selector family Type IEC : According to IEC standard (no circuit isolation, use -20°C +55°C, supply network +-10%, dielectric strength...
