TM 55-1930-209-14&P-1
f.
With engine idling, check that oil pressure gauge shows positive pressure. If not, stop engine.
Troubleshoot according to procedures in TM 55-1930-209-14&P-9, and correct problem.
g.
With engine idling, check that fuel pressure gauge on engine is in normal (green) range.
h.
With engine idling, check that coolant temperature gauge is registering. As engine warms up, gauge
starts to move toward higher reading. Engine can be switched from IDLE to RUN and a load applied
i.
On switchboard, set battery charger FLOAT/EQUALIZE switch to FLOAT.
j.
On switchboard control panel for starting SSG, check that:
(1)
VOLTMETER reads 440 Vac
(2)
FREQUENCY METER reads 60 Hz
(3)
AMMETER reads 0
3-19.5 Operating procedures. While engine is idling for 5 minutes, check operations as given in paragraph 3-7.4
NOTE
See paragraph 3-7.3 for operation of generator set alarms and shutoffs.
3-19.6 Shutdown procedures
3-19.6.1 Shutdown procedures from engine location. While SSG's are normally operated and shutdown from the
switchboard, these procedures provide for shutting down SSG's at the engine from an idling no-load status.
a.
Make sure all electrical loads have been transferred to other generator sets and applicable SSG circuit breaker
(P1 for SSG 1 or P2 for SSG 2) is open (OFF).
b.
Operate engine at idle speed for 5 minutes.
c.
At engine, push ENGINE START/STOP switch to STOP.
3-19.6.2 Emergency shutdown. For operating total barge shutdown and system shutdown systems, see paragraph
3-7.9 For emergency shutdown of the SSG at the engine:
a.
Push red EMERGENCY STOP button on side of generator housing.
b.
Turn ENGINE START/STOP switch to STOP.
c.
Reset EMERGENCY STOP button by turning clockwise and pulling out.
d.
Troubleshoot and correct problem requiring emergency shutdown.
Section VI. 20 kW ship auxiliary generator (SAG) set
3-20 Description. The 20 kW SAG set supplies limited amounts of electrical power for the barge when ROWPU systems
are not in operation. It provides sufficient power for operating normal lighting, dayroom equipment, workshop equipment,
and battery chargers. It must never be used to provide power for any major system onboard (TM 55-1930-209-14 & P-9).
3-20.1 This generator set consists of a Perkins Model 4.236M engine and a Newage Stamford SC144E generator
mounted, with vibration isolators, on a common base. It has free standing switching gear and is capable of parallel
operations. The set weighs 1300 pounds dry and 1451 pounds wet and is 74 inches long, 26 inches wide, and 40 inches
high. Installation is shown in engineering drawings listed in Appendix A.
