Fuel oil valve settings above are for operating auxiliary generator only. As other diesel engines are
needed, some of those valves listed as closed may be opened to supply fuel oil to other diesels. This will
not have any impact on fuel oil supply for this diesel.
Check that 24 Vdc power panel in workshop is active and circuit breaker 8P14 is dosed (ON) (Figure
3-18) to provide holding voltage to solenoids in fuel lines to generators. Emergency shutdown switches
activate these shutoff solenoids by removing this 24 Vdc power. If 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 stops the
Turn off all emergency panel power users and all emergency lights when all power
sources are turned off. If 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.
Check that generator set batteries are clean of corrosion, cable connections are tight and covered with
anticorrosion grease, and electrolyte covers the plates.
3-25.3 Starting procedures
Following procedures are for starting SAG engine from its location in void 4
starboard. For remote starting from switchboard in ROWPU space, see Section II.
On switchboard auxiliary generator control panel, make sure ENGINE CONTROL SWITCH is set to
Make sure switchboard circuit breaker P3 is open (OFF)
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 starts, throttle arm can be moved manually to momentarily increase engine speed. When
released, it will return to idle set with throttle knob on switchboard.
On switchboard, set AMMETER SWITCH to ON
Ear protection must be worn in voids 4 when any generator is operating.
On SAG, push ENGINE START/STOP switch up and hold until engine starts.
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
TM 55-1930-209-14&P-9. Correct as Indicated by chart.
With engine idling, check that lubricating oil pressure gauge shows positive pressure. If not, stop engine.
Troubleshoot according to TM 55-1930-209-14&P-9 and Troubleshooting Chart on page 67, Perkins
Engines Operations Manual for Marine Diesel Engines (in Appendix B, TM-55-1930-209-14&P-9).
