3-7.4 Operating procedures from switchboard. Starting procedures for the engines are in paragraph 3-19.3 for SSG's
and 3-25.3 for SAG. Operating procedures using shore power are in paragraph 3-7.6
Turn ENGINE CONTROL SWITCH (Figure 3-11) to START. Engine will crank and run.
Allow engine to idle for 2 minutes.
Monitor the following:
ENGINE FAILURE LIGHTS do not light (Figure 3-11).
Battery charger ammeter DC AMPS and DC VOLTS meters (Figure 3-15) indicate ammeter is charging
440 VOLT GROUND DETECTION lights do not light (Figure 3-12 or 3-13).
Turn VOLTAGE REGULATOR switch to RUN (Figure 3-11).
Wait 1 minute for engine to stabilize.
Monitor items listed in step c above.
Using AUTOMATIC VOLTAGE CONTROL RHEOSTAT, set generator voltage to 450 V.
Set generator frequency to 60 Hz.
On SSG 1 or SSG2, use GOVERNOR SPEED CONTROL toggle switch (Figure 3-11). Move it left to
increase frequency and right to decrease frequency.
On SAG, GOVERNOR SPEED CONTROL toggle switch is not connected (Figure 3-11). Set SAG
generator frequency by adjusting throttle on right side of switchboard. Turn throttle knob clockwise to
increase frequency and counterclockwise to decrease frequency.
Check ENGINE FAILURE LIGHTS (Figure 3-11) by pressing-to-test. Lights should light when pushed in. If not,
make note of bulbs to be changed when that generator is offline.
If this is first generator to be started and placed online, proceed with steps thru m.
If another generator Is currently providing power, follow procedures in paragraph
When the values in steps g and h are stable, close appropriate switchboard circuit breaker (Figure 3-14) to
provide generator output to switchboard bus:
P3 for SAG
P2 for SSG 2
P1 for SSG 1
Make sure switchboard GENERATOR status lights (Figure 3-14) for operating generator indicate it is running and
its circuit breaker is dosed.
With only SAG online, do NOT close circuit breakers P6, P7, P9, P12, or P15.
These circuit breakers engage power requirements beyond SAG's capacity. When
these circuits are necessary, start one of the SSG's, transfer load to SSG
(paragraph 3-7.5), and shut down SAG.
Apply load by dosing (ON), as required, switchboard circuit breakers P5 thru P13 and P15 thru P18 (Figure 3-13)
one at a time.
