Function
With mode switch in LOCAL posi-
tion unlatches STOP switch,
applies 50/60-Hz power to system
motor generator, SPCP fault
warning and shutdown circuits,
and peripheral equipment, and
applies 400-Hz power from system
motor generator to cabinet.
With mode switch in any REMOTE
position, unlatches STOP switch
so a remote control point
can perform to functions similar
to those above.
Removes 50/60-Hz power from
system motor generator, SPCP
fault warning and shutdown
circuits, and peripheral
equipment, and removes 400-Hz
power from cabinet. This action
occurs regardless of mode switch
position.

present at SPCP and that SYSTRM
DISCONNECT switch is in ON
position.
Indicates that POWER AVAILABLE
conditions are present, that
REMOTE ENABLE/LOCAL START
switch has been pressed, and
that 50/60-Hz power has been
