Main Control Console (CVN-65 and CV-67)
The main control console (fig. 4-64) is used in
conjunction with the deckedge control panel during
catapult operation. The control console consists of a
monitor panel, operating panel, steam panel, the launch
valve cutout valve, and the transfer switch enclosure.
MONITOR PANEL.—The monitor panel con-
sists of a series of status lights on the top right side for
various catapult system pressures. These lights will
indicate green for pressure within safe operating limits
or red for out-of-limit pressures. Malfunction lights are
located down the right side of the panel. These lights
will indicate red in the event of a malfunction. The
switches that energize these lights will also interrupt
the launching sequence. The monitor panel also
contains the launch vale stroke timers, and the digital
endspeed indicator.
OPERATING PANEL.—The operating panel is
used in conjunction with the deckedge panel during
launching
operations.
It
contains
the
lights,
push buttons, and switches that are used for catapult
control
during
launching,
retraction,
and
bridle
tensioning phases. The operating panel also contains
the CSV setting controls.
STEAM CHARGING PANEL.—The steam
charging panel contains steam pressure and tem-
perature gauges, status lights, and setting controls. The
setting controls provide a means of operating the fill
valves automatically or by a manually set air signal. In
normal operations, the fill valves are operated in
automatic charge. With automatic charge and charge
valve selected, the air signal to the fill valves is preset to
closely control the opening rates of the fill valves. The
manually loading air regulator is used to control the air
signal to the blowdown valve and to the fill valves when
in manual charge.
Transfer Switch Enclosure
The transfer switch enclosure is located on the
lower right side of the main control console. The
transfer switch enclosure provides a means of isolating
remote panels and switching control to the control
console. The transfer switches are rotated from
NORMAL to EMERGENCY, as required, to isolate a
remote panel that has malfunctioned.
Launch Valve Emergency Cutout Valve
The launch valve emergency cutout valve is located
on the lower left side of the main control console. The
