TM 55-1930-209-14&P-9-1 4-9.1 Remote control and startup requirements. While the three generator sets are located in voids 4, they are normally operated from the switchboard in the ROWPU space. Normally, one of the first actions upon entering the barge is to start the auxiliary (20 kW) generator to provide power for barge housekeeping activities. This generator does not provide sufficient power to support operation of moor ROWPU components, however, so prior to starting a major ROWPU component, one of the SSG’s must be brought online. Start an SSG, parallel it with the SAG, and transfer the load to the SSG. Then shut down the SAG. SECTION III. Operating Instructions 4-10. Operating controls and indicators 4-10.1 330B A diesel engine 4-10.1.1 Controls for operating engine at the SSG a. ENGINE CONTROL switch. This switch on SSG switchboard panel has START, REMOTE, and OFF/RESET positions. To start engine from switchboard, move ECS to START and engine will automatically crank and run. To start engine at the engine, move ECS on switchboard to REMOTE and use engine START/STOP switch on the engine. To stop engine from switchboard, move ECS to OFF/RESET. b. VOLTAGE REGULATOR switch. Located on switchboard. IDLE position allows engine to run at low speed for warm-up and maintenance checks. RUN position allows engine to run at full speed of 1800 rpm. While set on IDLE, generator’s circuit breaker connecting its power to the switchboard bus will not close. c. ENGINE START/STOP switch. Located on engine. ENGINE CONTROL SWITCH on switchboard must be in REMOTE for this switch to start the engine. Push switch up to start engine. Push switch down to stop engine. When stopping engine, ENGINE CONTROL SWITCH may be in any position. d. EMERGENCY STOP button. Located on engine. Push to stop engine. Resetting this button will start engine cranking and running unless ENGINE CONTROL SWITCH is set to OFF e. Seawater valves control flow of cooling seawater to SSG 1 and SSG 2 to cool engine coolant and lubricating oil. These valves must be open for engines to operate. (1) Seawater valve SW37. Located in void 4 port next to seawater strainer. When open, provides water from seawater strainer to manifold piping, which provides cooling seawater to all generators in voids 4. (2) Seawater valve SW49. Located in void 4 starboard on starboard bulkhead. When open, provides outlet for used cooling water to flow overboard. (3) SSG 1. Open SW valves SW38 and SW39 on side of engine. (4) SSG 2. Open SW valves SW40 and SW41 on side of engine.* • These SW valves have temperature gauges with each valve to indicate ingoing and outgoing water temperatures. 4-10.1.2 Engine indicators. Engine indicators are on switchboard SSG engine panel, with exception of the following which are on the engine: fuel pressure gauge indicator, oil dipstick, engine alternator ammeter, oil pressure gauge, service meter, coolant level indicator, and coolant temperature gauge. a. Oil pressure gauge. Left-hand gauge on engine instrument panel indicates oil pressure in pounds per square inch (psi) on the bottom scale. Scale reads 0-10-30-50-70. When engine is new, its normal oil pressure indication is obtained by operating engine at normal temperature and maximum rpm. Mark this oil pressure reading on gauge rim to indicate normal operating range. b. Oil dipstick Shows amount of oil in engine crankcase. Oil level must be between ADD and FULL marks on dipstick. 4-3
