SYSTEM
(Cont~nued)
BATTERY SWITCH
The battery switch is a two-position toggle-type switch, labeled
BATTERY, and is located on the left sidewall switch and circuit breaker
panel. The battery switch is ON in the
fonvard position and OFF in the
aft position. When the battery switch is in the ON position, battery
power is supplied to the two general buses. The OFF position cuts off
power to all buses except the battery bus.
STARTER SWITCH
The starter switch is a three-position toggle-type switch, labeled
STARTER, on the left sidewall switch and circuit breaker panel. The
switch has OFF, START, and MOTOR positions. For additional details
I
of the starter switch, refer to the Starting System paragraph in this
section.
IGNITION SWITCH
The ignition switch is a two-position toggle-type switch, labeled
IGNITION, on the left sidewall switch and circuit breaker panel. The
switch has ON and NORMAL positions. For additional details of the
ignition switch, refer to the Ignition System paragraph in this section.
GENERATOR SWITCH
The generator switch is a three-position toggle-type switch, labeled
GENERATOR, on the left sidewall switch and circuit breaker panel. The
switch has ON, RESET, and TRlP positions. With the switch in the ON
position, the GCU will automatically control the generator line contactor
for normal generator operation. The RESET and TRlP positions are
momentary positions and are spring-loaded back to the ON position. If
a momentary fault should occur in the generating system (as evidenced
by the GENERATOR OFF
andlor VOLTAGE LOW lights illuminating),
the generator switch can be momentarily placed in the RESET position
to restore generator power. If erratic operation of the generating system
is observed, the system can be shutoff by momentarily placing the
generator switch to the TRlP position. After a suitable waiting period,
generator operation may be recycled by placing the generator switch
momentarily to RESET.
