CAUTION
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.
k
Check that seawater is available for heat exchanger.
(1)
Make sure both stem seawater strainer baskets are dean and operable. For details on servicing these
strainers, see TM 55-1930-209-14&P-2, Seawater System.
(2)
Open seawater valves SW45 and SW46 in void 4 port to monitor pressure drop across strainers (Barges 2
and 3 only). 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).
(3)
Open seawater valve SW37 in void 4 port and SW49 in void 4 starboard.
(4)
For SSG 1: Open seawater valves SW38 and SW39 in void 4 port.
(5)
For SSG 2: Open seawater valves SW40 and SW41 in void 4 starboard.
I.
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,
SEBU5717-02.
3-19.4 Starting procedures at the engine
NOTE
Normally, SSG's 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 SSG's, with no load, from engine location In voids 4. For starting from
switchboard In ROWPU space, see Chapter 2, TM 55-1930-209-14 & P-9.
a.
On switchboard control panel for starting SSG, set ENGINE CONTROL SWITCH to REMOTE.
b.
On switchboard control panel for starting SSG, set VOLTAGE REGULATOR switch to IDLE.
c.
On switchboard, check that GENERATOR circuit breaker (P1 or P2) for starting generator is OPEN.
d.
On switchboard, set AMMETER SWITCH to ON.
WARNING
Ear protection must be worn in voids 4 when generators are operating.
e.
On starting SSG, push ENGINE START/STOP SWITCH up and hold until engine starts. Release switch when
engine starts. Engine should start and operate at idling speed.
NOTE
If engine does not start within 30 seconds, release ENGINE START/STOP SWITCH.
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 procedures on page 53, Caterpillar Systems Operation Testing and
Adjusting for 3304B & 3306B Generator Set Engines, Form No. SENR2797 in
Appendix B of TM 55-1930-209-14&P-9.
