system for the MEP 831A is a thermostatically cooled by two
fans.
d.
The MEP 831A has a single-cylinder, air cooled, direct

between 3000 to 3600 RPM (6.7 HP at operating speed). The
maximum RPM rating is 3800 RPM. The diesel engine for a MEP 831A
has an oil capacity of 1.2 quarts (1.1 liters), and is consumed
at 0.04 ounce (1.18 ml) per hour at a rated load.
e.
The MEP 831A is equipped with a four gallon fuel tank,
allowing eight hours of continuous operation at a full load. The
MEP 831A is designed to consume .5 gallons per hour at a rated
load. When the MEP 831A is connected to an auxiliary fuel
system, it will be continually replenished. The MEP 831A is
designed to use either diesel fuel type 1 (DF1) or 2 (DF2), and
turbine fuel JP-8.
f.
The MEP 831A has 24VDC cranking system. The MEP 831A has
a Permanent Magnet Alternator (PMA) with a frequency converter.

Page 2: Physical Description
2 wire, 120VAC, or single phase, 3 wire, 120/240VAC. The current output for the MEP 831A is 31 amps max for 120VAC, and 16 amps max for 120/240VAC. PHYSICAL DESCRIPTION Generator Set: Manufacturer Fermont Model MEP-831A Fuel Tank Capacity (gal) Fuel Type Diesel/JP-8 Engine Manufacturer Yanmar Model... - Page 3 WARNING Engine exhaust gas (Carbon Monoxide) is a deadly odorless, colorless, poisonous gas. Avoid breathing it. (2) Enclosure Cooling and Ventilation System. intake openings and engine intake ducts at the rear of the enclosure assembly allow for the engine cooling using external air.
- Page 4 (6) Control Box Assembly. The control box assembly is mounted to the enclosure assembly at the rear of the generator set. Instruments, controls, and indicators required to operate the generator set are located on the control box assembly. control box assembly consists of a control panel (18, Figure 1- 2), ground fault circuit interrupter, (13) (60Hz only).
- Page 5 (6) BATTLE SHORT ON. WARNING Exposed fuel and fuel vapor can ignite or explode, resulting in possible serious injury or death. (7) Output Terminals and Slave Receptacle. The output terminal board and ground terminal are located on the generator set skid base, just below the control box assembly. A hinged cover (16, Figure 1-2) allows access to the three load terminal and single ground terminal.
- Page 6 (9) Engine. The generator set is equipped with a single cylinder; air cooled, direct injection, four stroke cycle, diesel engine (14, Figure 1-3). The engine is designed to operate between 3000 and 3600 RPM. The engine has self-contained oil lubrication and fuel systems. The engine is equipped with an air filter (2), muffler (3), 24VDC starter motor (4), manifold heater (15), engine high coolant temperature switch...

Page 10: Description And Use Of Operators Controls And Indicators
DESCRIPTION AND USE OF OPERATORS CONTROLS AND INDICATORS. Prior to placing the generator set into operation, personnel must be familiar with the location and function of all switches, controls and indicators. Controls and indicators required for generator set operation are described below and identified on Figure 2-1. -
Page 11: Ground Fault Circuit Interrupter (Gfci)
(9) CONVENIENCE RECEPTACLE. (60Hz only) Single phase duplex receptacle which allows 120VAC appliance or tool connection. (10) GROUND FAULT CIRCUIT INTERRUPTER (GFCI). (60Hz only) Provides automatic circuit interruption and circuit protection for the convenience receptacle. (11) SLAVE RECEPTACLE. Allows for 24VDC auxiliary power connection for starting generator set. -
Page 12: Engine Oil Drain Plug
(19) PREHEAT Switch. Two-position switch that controls the engine preheat system. (a) ON position sends a signal to engine preheat contactor to energize the engine air heater. Used during cold weather operation. (b) OFF position de-energizes the engine air heater, halting engine preheat operations. - Page 13 (28) LUBRICATING OIL PRESSURE Switch. Monitors engine oil pressure. If oil pressure drops below 15 PSI, the switch closes the circuit to energize the fault lockout relay and shuts down the engine. The LOW OIL PRESSURE indicator on the fault indicator module will light.
- Page 17 GROUNDING. Grounding of generators to earth is essential to place the generator at earth potential, preventing hazards to operators and draining static charges or stray current harmlessly to earth. The generator neutral output terminal (LO) is intentionally bonded to the generator grounding terminal on its frame or chassis which is then connected to earth.
- Page 18 (6) Repeat steps 4 and 5 until ground rod has been driven 8 feet or deeper, providing an effective ground. Connect clamp (6) and ground cable (1) to ground rod (4). Tighten clamp and screw securely to prevent movement. (7) Ground rod must be installed within five feet or less from the generator.
- Page 19 MEP-831A GENERATOR SET OPERATIONS. Before Operations PMCS. A before operations check is exactly what it sounds like, certain checks that are performed before a piece of equipment is operated. This is also known as a “360°,” since 360 is a complete circle. As the operator you will do a complete inspection of the equipment, visually and manually inspecting the piece of gear.
- Page 20 (9) Ensure NATO slave receptacle has no damage or shows any signs of electrical shock or corrosion. (10) Ensure the output panel door locking latch operates properly, also check the load and ground terminals to ensure they are securely attached. (11) Check exhaust system for cracks, holes, or dents.
- Page 21 Shutdown Procedures. (1) Place the AC CIRCUIT INTERRUPTER switch in the OPEN position. Allow the generator 3-5 minutes to cool down the engine. (2) Place the START/RUN/STOP switch in the STOP position. (3) Pull out the DC CIRCUIT BREAKER. NOTE GENERATOR MUST BE SHUT DOWN EVERY 8 HOURS TO SERVICE OIL AND FUEL WATER SEPERATOR.
- Page 22 (9) Ensure the output panel door locking latch operates properly also check the load and ground terminals for security of attachment. (10) Check exhaust system for cracks, holes, or dents. (11) Inspect muffler for damage. (12) Ensure the engine fuel system components are free from damage or leaks.
- Page 30 PREVENTATIVE MAINTENANCE CHECKS AND SERVICES (PMCS). Visual and Physical Inspection. Before any type of maintenance can be performed, the first thing that needs to be done is a thorough visual and physical inspection of the equipment, along with documenting discrepancies on the NAVMC 10560 Technical Inspection form.
- Page 31 FINDING REQUIRED MAINTENANCE. (Refer to Table 2-2) When the need for preventive maintenance has been identified, the operator must turn to the right place to find exactly what to do. Each piece of equipment has specific requirements to keep it running in peek condition. Because most pieces of equipment are different, the operator should check the appropriate Technical Manual (TM) for instructions on when and how to conduct preventive maintenance.
