Central Charging Panel The central charging panel (fig. 4-82) is located below decks in the retraction-engine compartment. The panel consists of the left-front panel, left-intermediate- front panel, right-intermediate-front panel, right-front panel, transfer-switch panel, and launching-valve- emergency-cutout-valve panel, which are described in the following paragraphs. The deck-signal-light panel is located inside the central charging panel, below the left-intermediate front panel. Controls on the deck- signal-light panel are used to adjust the intensity of the deck signal lights. The panel enclosure also contains pressure switches, gauge shutoff valves, and other piping components. LEFT-FRONT PANEL.— The left-front panel controls and monitors the hydraulic system. The panel contains pressure gauges and OFF-ON switches for the main hydraulic pumps, the auxiliary pump, the circulating pump, and the lubrication pump. Also included are a gravity-tank fluid temperature gauge, three accumulator hydraulic-pressure gauges, an OFF-ON PUMP DELIVERY CONTROL switch, RETRACTION-ENGINE SUSPEND switch, a blowd- own valve for the retraction-engine hydraulic fluid, and fuses. LEFT-INTERMEDIATE-FRONT PANEL.—The left-intermediate-front panel controls and monitors the pneumatic system. Gauges on the panel indicate the air pressure in the air side of the main hydraulic accumulator, the air flask, the air side of the cable-tensioner accumulator, the low-pressure-air supply, medium-pressure-air supply, and the air side of the tensioner surge accumulator. A dual gauge indicates the air pressure at the dome of the tensioner regulator and the pressure in the hydraulic fluid side of the tensioner surge accumulator. Valves on the panel are used for charging and blowing down the air flask, the air side of the main hydraulic accumulator, internal tensioning accumulator, the air side of the cable- tensioner accumulator, the dome of the tensioner regulator, and the air side of the tensioner surge accumulator. There is also a valve to shut off the low-pressure-air supply. Lights on the panel indicate pressure and temperature limits for various catapult functions. RIGHT-INTERMEDIATE-FRONT PANEL.— The right-intermediate-front panel contains gauges for monitoring the pressure of the two nose-gear-launch accumulators. Two air valves on the panel are used for charging and blowing down the nose-gear-launch- manifold accumulator. The panel also contains the 4-62 Figure 4-82.— Central charging panel.
