EQUIPMENT DESCRIPTION
1-6
The generator sets, models MEP-803A and
MEP-813A (FIGURE 1-2), are fully enclosed, self-contained.
skid-mounted, portable units. They are equipped with controls.
instruments and accessories necessary for operation. The
generator sets consist of a diesel engine, brushless generator.
excitation system, speed governing system, fuel system, 24
VDC starting system, control system and fault system.
NOTE
All locations (FIGURE 1-2) referenced in
FIGURE 1-2 are given facing the control box side
(rear) of the generator set.
1-7
1-7.1 The generator is powered by a four
cylinder, four cycle, fuel injected, naturally-aspirated.
liquid-cooled diesel engine which occupies the front half of the
generator set. The engine is also equipped with a fuel
filter/water separator, oil falter, and an air cleaner assembly.
Protection devices automatically stop the engine during
conditions of high coolant temperature, low oil pressure, no
fuel, over-voltage.
1-7.2 Radiator (9).
The radiator is located at the front of
the generator set. It acts as a heat exchanger for the engine
coolant.
1-7.3 Muffler (12). The muffler and exhaust tubing are
connected to the exhaust manifold on the engine. The exhaust
exits from the top of the generator set housing. Gases are
exhausted upward.
1-7.4 Starter (15). The starter is located on the right side
of the engine. The electric starter mechanically engages the
engine flywheel in order to start the diesel engine.
1-7.5
The batterly
charging alternator is located on the right side of the engine. It
is capable of maintaining the batteries in a state of full charge
in addition to providing the required 24 VDC control power.
1-7.6 Batteries (7).
Two batteries are required, one on
each side of the generator set. The batteries are maintenance
free, lead acid, 12 volt type, connected in series. After starting,
the generator set is capable of operating with batteries
removed. A fuse and a diode, located behind the control panel
assembly, protects the generator set if the batteries are
incorrectly connected.
