VOLTAGE REGULATOR CONTROL
SWITCH.--This switch is located next to the
voltage regulator control mode switch/indicators
and is labeled VOLT. It is a three-position switch,
spring loaded to the center position. The center
position is labeled OFF, which is the normal
position of the switch. When the switch is turned
to the right or the RAISE position, it will cause
the voltage of the generator to increase. When the
switch is turned to the left or the LOWER

position, it will cause the voltage of the generator
to decrease.
This section is located in the lower left-hand
corner of the panel. It has two select switches. The
top switch controls the input to the synchroscope
and synchronizing lights and the bottom switch
controls the mode of operation of the console and
the paralleling device. These switches are labeled
SYNC SELECT and OPR MODE SELECT,
respectively.
SYNC SELECT SWITCH.--This is a rotary
switch used to select between the GBs, the BTBs,
or the shore power circuit breaker. It connects the
inputs from both sides of the selected breaker to
the synchroscope and synchronizing lights, located
on the alarm/status panel. This switch also allows
the breaker selected to receive a manual close
command when it is operated in the MANUAL
PERMISSIVE mode.
