ELECTRIC PLANT CONTROL
CONSOLE (DD-CLASS SHIPS)
The EPCC on the DD-class ships contains the
controls and indicators used to operate and
distribution systems remotely. The control system
on the DD-class ships is the EPCE (fig. 8-1).
It consists of an EPCC and an electric plant
control electronics enclosure (EPCEE). In this
section we will discuss the EPCC. The EPCC is
subdivided into four panels, and each panel is
dedicated to a particular type of control and
monitoring. The panels are the alarm/status
panel, the generator status panel, the mimic panel,
and the system control panel. We will discuss each
panel of the console and point out the purpose
or the function of each indicator, switch/
indicator, or switch. We will also discuss the
TOPS, load centers, and the different system
configurations.
