a. The control of plant operation by personnel or computers housed under
conditions that can be remote, safe, and convenient. This is a feature of
both electrical and electronic automatic control. In the control room,
various plants can be started up by pushbutton and the governing
conditions can be set. Instrumentation records all relevant data; it also
gives warning of unsafe conditions and shuts down the plant if no
correction is made. Changeover switches can introduce different operations
and sequences in the working of the plant. Indicating lights can show what
plant is working and the progress made. Fault indication can show the
reason in the event of a shutdown. Also called centralized control.
Nelson
b. A term applied to a switch, circuit breaker, starter, or similar
apparatus, to denote that its operation can be controlled manually, from a
distance, by electrical or other means. BS, 13
