They are switched on when the effective range of steady burning approach lights at full intensity becomes insufficient to insure adequate guidance. Since it may also be desirable to operate such systems under good visibility conditions, for instance to facilitate the location of the runway in urban areas, the use of a 3-level system avoids dazzling. Flashing lights may be used as: • Sequenced flashing lights (SFL) in (non-) precision approaches, • Runway threshold identification light systems (RTILS), • The combination of the above SFL and RTIL systems • To add a runway alignment segment to a medium-intensity approach lighting (system MALSR), • Lead in (LDIN) approach lights (on request). Features • 400 V flash tube for improved overall security compared to 2 kV. • Low mass elevated flash head incorporates triggering electronics for faultfree firing of flash tube. • The Flashing Control Unit (FCU) exists in a FCU-1 and a FCU-3 version. The FCU-3 version houses three single FCUs in one common enclosure. User benefits: ■ Lower acquisition and installation costs ■ Perfect balancing of loads over the three phases ■ Easier to service ■ Improved safety thanks to fully protected cable runs • New high power factor power supply yields lower power consumption, and eliminate peak inrush currents during capacitor charging phase. Smaller cross-section cables for input power required. • The FCU adjusts itself automatically to any input voltage from 190 to 260 V AC, 50 or 60 Hz. Available for single or three phase (3 or 4 wires) power supply. • Wiring between FCU and flash head uses standard, 4-core plus earth, low voltage cable. • Remote control and monitoring via single or dual field bus, 24 or 48 V multi-wire or a combination of both. • Distance between FCU and flash head: 120 m and over without light output loss or misfiring. Required energy to reach specified light output is always guaranteed into the flash tube. • Microprocessor controlled design allows user-adjustable parameter setting and configuration, detailed individual status monitoring, software update via Flash EEPROM upload, (all optional) and condensation prevention. • Lightning surge protection 6,5 kA 8/20 µs included as standard. Extended protection up to 80 kA recommended for lightning sensitive areas available as an option. Combines the best out of two worlds: direct line coupled and capacitor discharge flashing systems. A.02.620e General description The ADB low voltage capacitor discharge flash light system consists of up to 32 flashing lights with individual control units. The fixtures are available as elevated and inset unidirectional applications. All Flasher Control Units are electrically identical. They can be supplied as pole mounted cabinets for each individual flashing head or – recommended – as 3-in-1 units to control three flashing lights from one cabinet only. In the latter case, the cabinets are mounted on a pedestal, offering the advantage of a most easy access for installation or servicing even as a complete mechanical protection of the in- and outgoing cables. Thanks to the built-in compensation for the cable length, the FCU-3 cabinets can be placed outside the obstacle limitation area. Electrical equipment description The flashing control units are designed for the supply of 400 V DC flash tubes. The flash energy required for each of the 3 individually adjustable levels is stored in a capacitor. The trigger electronics are located in the flashing light. Any cabinet in the system can be designated as the Local Master Controller (LMC) by adding a Master PCB. The LMC assures the synchronization between the cabinets, incorporates the master for the local bus, and serves as interface between the flashing system and the control system. Via a standard PC and a dedicated “dongle”* (optional), most of the parameters as well as the system configuration can be optimized to the on-site conditions. The electrical connections between the substation and the FCUs and between each light fixture and its control cabinet use standard low voltage cabling. The latter connection can be up to 120 m without loss of light output. Remote control is realized via multiwire, single or double field bus or any combination thereof. All cabinets are equipped with microprocessor controlled anti-condensation heating. 9 2 1 4 *Details on application Electrical supply The system is powered either from a three-phase (3 or 4 wire) or a singlephase power system, providing a voltage between phases of 190 to 260 V 50/60 Hz. In case FCU-3 control cabinets are used, the load balancing over the three phases is almost automatic. As soon as power is applied, the wiring arrangement allows the anticondensation heater(s) to operate, even while the Flashing Light system is switched off. 6 5 7 Fig. 3 FCU-3 Fig. 4 FCU-1 9 2 4 5 6 7 Construction Control cabinets (FCU-3 & FCU-1) (Fig. 3 & Fig. 4) 1.

If installed inside, the installation needs to be frangible. In order to limit the effect of the jet blast, it is recommended to install the cabinets with their largest vertical surface parallel to the approach axis. Flashing lights (Fig. 11 to 14) The inset light can be mounted on an ADB 12˝ shallow base with 100 mm Ø central hole (Fig. 11), on a FAA L868-B deep base (Fig. 12), by means of a 12˝ to 16˝ adaptor ring on a deep FAA LB-4 base (Fig. 13). Bases need to be ordered separately. When installing the control units outside the safety area, the elevated flashing lights can be installed like any other steady burning approach light. dia 330 Fig. 11 FFL Dimensions in mm In case of pole-mounted, 1-in-1control cabinet in the approach, the elevated light can be installed on top of the pole supporting the individual control cabinet. In the latter case, all exposed cables need to be suitably protected. (See Fig. 14 for typical installation). Options • Additional surge protection: The standard control electronics are protected by MOV’s against over voltages up to 6.5 kA 8/20 µs. An optional protection for surges up to 80 kA 8/20 µs is recommended for any lightning sensitive area. • 230 V Mains socket outlet: FCU boxes can be supplied with built-in socket outlet to ease servicing activities in the field and at night.

Any control unit of the system shall be able to be used as „master”. The communication between the ATC tower and the flashing system shall be realized either via a multi-wire cable, one or two dedicated local buses or a combination of these and shall permit a complete status monitoring and remote control of each individual control unit (over a local bus).
