With engine idling, check that fuel oil pressure gauge shows normal fuel pressure. If not, change fuel oil
filters as provided in TM 55-1930-209-14&P-9.
On switchboard, set battery charger FLOAT/EQUALIZER switch to FLOAT.
With engine idling, check that coolant temperature gauge is registering. When gauge starts to move
toward higher reading, engine speed may be increased, using throttle on side of the switchboard.
On SAG switchboard control panel, check that:
VOLTMETER reads 440 Vac
FREQUENCY METER reads 60 Hz
AMMETER reads 0.
3-25.4 Operating procedures. After starting, the SAG is difficult to operate from the engine location, due to limited
throttle control. It is normally operated from the switchboard. For operating procedures from the switchboard, see
See paragraph 3-7.3 for operations of generator set alarms and shutoffs.
During operation, perform during operation checks according to paragraph 3-7.4
During operation, make sure that lubricating oil pressure, fuel oil pressure, and coolant temperature
gauges indicate normal range of operation.
3-25.5 Shutdown procedures
3-25.5.1 Shutdown procedures at engine. While this auxiliary generator set is normally operated from switchboard, it
can be shut down at the engine location by following these procedures:
Make sure all electrical loads have been transferred to other generator sets and SAG circuit breaker P3 is
At switchboard, decrease throttle setting to idle (900 rpm) by pushing in on central button and then
pushing throttle knob all the way in and turning clockwise as far as it will go.
Operate engine at idle speed for 5 minutes.
At engine, push ENGINE START/STOP switch to STOP.
3-25.5.2 Emergency shutdown. For activating total barge shutdown and individual system shutdowns, see paragraph
3-7.9. For emergency SAG shutdown at the engine:
Push red EMERGENCY STOP button on side of generator housing.
Turn ENGINE START/STOP switch to STOP.
Troubleshoot according to procedures on page 67 of Troubleshooting Chart in Perkins Engines Operators
Manual for Marine Diesel Engines 4.236M, in Appendix B of TM 55-1930-209-14&P-9.
When corrections have been completed, reset EMERGENCY STOP button by turning clockwise. Button
will pop out and be in ready position.
