Figure 5-5.—Equipment interconnection through the CDS DFCS.
The DFCS is comprised of two or more
switchboard sections (fig. 5-3) covered with variable
configurations of switch panels. Each panel type
performs a specific function. The 24 panels per
section are normally arranged in groups according to
the functions performed by the panels. The front
panel of each switchboard section is hinged on the left
side to allow access to the interior of the switchboard.
The interior of the switchboard (fig. 5-6) contains a
system of modules and terminal board connectors
that allow ship’s wiring to be
interconnected to the appropriate switch panels.
The switchboard panel locations are numbered for
identification purposes starting at the upper-left
corner of the switchboard. The numbering continues
from top to bottom, left to right. Each panel is
marked with a designation plate mounted on the
upper-left corner of each panel assembly or with a
blank plate.
Power Distribution Panel
The power distribution panel (fig. 5-7) provides a
visual indication of power supplied to the
switchboard. Six indicators are mounted on the front
of the panel and lighted when the appropriate power
has been applied to the panel and is distributed to the
remainder of the switchboard.
Linear Movement Switch
Assemblies
The majority of panel assemblies are linear
movement switch assemblies. These assemblies route
a specific number of circuits. The linear movement
switch assemblies are normally positioned by control
signals from the CSCP, but they may be manually
positioned.
Two types of linear movement switch assemblies
are the R3DLSO-1B/R5DLSO-1B
