g.
Check that fuel oil is available by setting fuel oil valves as follows:
Open: F018, F019, and F025
Close:F013 thru F017, F020 thru F024, F026, and F027.’
• Fuel oil valve settings above are for operating auxiliary generator only. As other diesel engines are needed,
some of those valves listed as dosed may be opened to supply fuel oil to other diesels. This will not have any
impact on fuel oil supply for this diesel.
h.
Check that 24 Vdc power panel in workshop is active and circuit breaker 8P1 4 is dosed (ON) (Chapter
3) (Figure 3-2) to provide holding voltage to solenoids in fuel lines to generators. Emergency shutdown
switches activate these shutoff solenoids by removing this 24 Vdc power. It 24 Vdc panel is not active, these
holding solenoids are closed. The generator will start and run for a few minutes until lack of fuel shuts it off.
CAUTION
Turn off all emergency panel power users and all emergency lights when all power sources are
turned off. It not, battery bank will be drained of power. Without power from this battery bank to
hold fuel shutoff solenoids open, generators will not operate to recharge the 24 Vdc batteries.
i.
Check that generator set batteries are dean of corrosion, cable connections are tight and covered with anti-
corrosion grease, and electrolyte covers the plates.
5-12 Starting procedures
NOTE
Following procedures are for starting SAG engine from its location in void 4 starboard. For remote starting
from switchboard in ROWPU space, see Chapter 2.
a.
On switchboard auxiliary generator control panel, make sure ENGINE CONTROL SWITCH is set to REMOTE.
b.
Make sure switchboard circuit breaker P3 is open (OFF).
c.
On switchboard, make sure throttle knob is pushed all the way in and turned clockwise as far as it will
go. This sets throttle for starting and idling at about 900 rpm. Throttle cannot be set until engine has started.
After engine start, throttle arm can be moved manually to momentarily increase engine speed. When
released, it will return to idle set with throttle knob on switchboard.
d.
On switchboard, set AMMETER SWITCH to ON.
WARNING
Ear protection must be worn in voids 4 when any generator is operating.
e.
On SAG, push ENGINE START/STOP switch up and hold until engine starts.
NOTE
If engine does not start within 20 seconds, release ENGINE START/STOP SWITCH and wait 2 minutes
for starter motor to cool. Then, try again. Release switch when engine starts. If engine does not start after
three attempts, troubleshoot by following troubleshooting procedures on page 67, Perkins Engines
Operators Manual for Marine Diesel Engines, 4.236M, found in Appendix B. Correct as indicated by chart.
