Red EMERGENCY STOP button on engine control panel. Push to stop engine. When emergency situation
has been corrected, reset by turning clockwise and button will pop out to normal position. Start engine by
following normal starting procedures.
Seawater valves control flow of seawater to SAG 1 for cooling engine coolant and lubricating oil. These valves
must be open for engine 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.
Seawater valve SW49. Located in void 4 starboard on starboard bulkhead. When open, provides outlet
for used cooling water to flow overboard.
Seawater valve SW42. Controls flow of cooling seawater from aft seawater seachest strainer to inlet into
engine cooling exchanger. Valve piping also includes a temperature gauge indicating inlet water
temperature. Valve must be open for engine to operate.
Seawater valve SW43. Controls flow of cooling seawater from engine cooling exchanger to overboard
outlet. Valve piping also includes a temperature gauge indicating temperature of water leaving the engine
heat exchanger (Barges 2 and 3 only). Valve must be open for engine to operate.
SC1 44E generator. Controls and indicators are on switchboard in ROWPU space. These are discussed in
Chapter 2, paragraph 2-10.2, as part of the normal electrical system.
5-11 . Prestart procedures
In ROWPU space, make sure EMS is operating by pushing up on monitor controller left of monitoring
processor. If video monitor screen does not come on, turn it on with switch beneath the screen. For more
details on EMS, see TM 55-1930-209-14 & P-11.
Check maintenance records to make sure all required maintenance checks and services have been
completed and no deficiencies exist that would prevent safe and proper equipment operation.
In void 4 starboard, inspect generator set for visible deficiencies that, if not corrected, could become
hazardous to people or equipment.
Never overfill crankcase. Fill only to maximum level as indicated on dipstick.
Check crankcase engine oil level on dipstick on left side of engine. N not up to full mark, add lubricating oil
through filler on top of engine. Use SAE 1 5W40 that meets Military Specification MIL-L-21 04C (API CD). If
temperature in the voids consistently exceeds 1200F, use SAE 40.
Check coolant level in heat exchanger (header) tank Level should be less than 1 inch below bottom of neck
opening. If necessary, add dean fresh water to bring to required level. Cooling system has an anti-corrosion
zinc anode in coolant heat exchanger. Water conditioner, therefore, is not required or desirable.
Check that seawater is available for heat exchanger.
(1) 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 (on Barges 2 and 3 only) to monitor pressure drop across
strainers. H pressure difference during operation becomes greater than 8 in. Hg, turn handle to direct
water through other basket. Clean dirty basket according to TM 55-1930-209-14 & P-2, Seawater
Open seawater valve SW37 in void 4 port and SW42, SW43, and SW49 in void 4 starboard.
