NAVIGATION AIDS SYSTEM EQUIPMENTEMERGENCY SYSTEM

Suitable for high reliability navigation aids system that is equipped with redundant control circuits (main control circuits, placed in the centralized c o n t r o l p a n e l a n d emergency circuits). The aim of this system is to drive the signal lights and fog horns during the Electrical Shut-Down (ESD) phase and when the centralized control panel is not working. The system is composed by battery cut-off circuit and emergengy circuits. This equipment is made in explosion proof enclosures, s u i t a b l e f o r o u t s i d e installation in classified area, zone 1 and 2, ATEX certified.

Battery cut-off circuit (distribution panel)

The cut-off battery circuit supplies, from battery voltage directly, the emergency

circuits and the hazard beacons (if installed). This equipment connects the

battery charger, installed in the control panel, with the battery system placed in

the battery room by a bipolar breaker. The circuit is controlled by a security

system of the platform. During the "ESD phase" the bipolar breaker switch off,

causing the insulation between the battery and the control panel. During this

phase the control panel is not powered and the navigation aids equipment ( fog

horns and signal lights) is driven by emergency control circuits. The breaker is

suitable for the max. current supplied by the battery charger. The enclosure,

containing this circuit, is suitable for wall installation and can be supplied

complete with mechanical support (optional).

Main characteristics:

- Enclosure material = Light alloy

- Enclosure execution = EEx-d-IIB-T6 IP 65

- Enclosure painting = RAL 6003 standard (other color on request)

- Working voltage = 24 VDC standard (other voltage on request)

- Battery breaker current = Max. 250 A (on request)

- Remote control = Provided

Emergency circuit

The aim of emergency circuit is to drive fog horns and signal lights installed in

the platform during “ESD” phase (No. 2 signal lights and No. 1 fog-horn for each

circuit). The circuit is made by using microprocessor C-MOS type. It is always

powered and, during normal working phase, kept in stand-by conditions at very

low consumption. This circuit is provided with LOCAL PHOTOCELL and, when

necessary, is equipped with a synchronization circuit (with another emergency

circuit) that allows all signal lights and all fog-horns to work in synchronism. The

enclosure, containing the circuit, is suitable for wall installation and can be

supplied complete with mechanical support (optional).

Main characteristics:

- Enclosure material = Light alloy with glass window

- Enclosure execution = EEx-d-IIB-T6 IP 65

- Enclosure painting = RAL 6003 standard (other color on request)

- Working voltage = 24 VDC standard (other voltage on request)

- Stand-by consumption = 1W approx.

- Capacity = Driver for max 2 signal lights and 1 fog horn

- Remote controls = Provided
