Check that fuel pressure gauge indicates NORMAL. If gauge indicates CAUTION or OUT, wash primary fuel
filter and replace secondary fuel filter element. (Refer to step 4-1 8.3a for details.)
Drain water and sediment from fuel water separator (it SSG is so equipped).
Check that engine has fuel oil (for further information on fuel oil system, see TM 55-1930-209-14 & P-8) by
setting fuel oil valves as follows:
For SSG1: Close fuel oil valves F013-FO15, FO17, Fo18, F20, 1021, F24-F27, and open fuel
valves F016, F019, and F023.
For SSG2: Close fuel oil valves F013-FO16, Fo18, F020,10)21,F0O23, F025-F027 and open
Fo17, F019, and F024.
j. Check that 24 Vdc power panel in workshop is active (Chapter 3) and circuit breaker 8P1 4 is closed (ON).
This action provides voltage to hold open solenoids in generator fuel lines. Emergency shutdown switches
activate these shutoff solenoids by removing this 24 Vdc power. If 24 Vdc panel is not active and circuit
breaker 8P1 4 is open (OFF), these holding solenoids are closed and fuel for these generators is shut off. The
generator will start and run for about 2 minutes until lack of fuel shuts it off.
Turn off all emergency panel power users and all emergency lights when all power sources are
turned off on barge. If not, DC battery bank will be drained of power. Without DC power to hold
these fuel cutoff solenoids open, generators will not operate to recharge the 24 Vdc battery bank
Check that seawater is available for heat exchanger.
Make sure both stern seawater strainer baskets are dean and operable. For details on servicing
these strainers, see TM 55-1930-209-14 & P-2, Seawater System.
Open seawater valves SW45 and SW46 in void 4 port to monitor pressure drop across strainers. If
pressure difference during operation becomes greater than 8 in Hg, turn handle to direct water through
other basket. Clean dirty basket (TM 55-1930-209-14 & P-2, Seawater System).
Open seawater valve SW37 in void 4 port and SW49 in void 4 starboard.
For SSG 1: Open seawater valves SW38 and SW39 in void 4 port.
For SSG 2: Open seawater valves SW40 and SW41 in void 4 starboard.
l. On SR4 generator, if SSG has not run under load within last 3 months or SSG has been in storage, follow
procedures provided on page 20, Caterpillar Operation and Maintenance Manual for SR4 and SRCR
Generators, SEBU571 7-02.
4-12. Starting procedures at the engine
Normally, SSGs are started at switchboard In ROWPU space. Starting these engines at the engines
In voids 4 can be done when necessary, such as Initial starting after storage or after maintenance
or repair. Following procedures are for starting SSGs, with no load, from engine locations In voids
4. For starting from switchboard In ROWPU space, see Chapter 2.
On switchboard control panel for starting SSG, set ENGINE CONTROL SWITCH to REMOTE.
On switchboard control panel for starting SSG, set VOLTAGE REGULATOR switch to IDLE.
