Instructions in this section are provided for
information and guidance for personnel responsible for
operation of the generator set.
The operator must know how to perform
every operation of which the generator set is capable of
performing. This section describes and illustrates the
various controls and instruments required to operate the
supporting illustrations for operating the generator set
under normal conditions.
The purpose and location of generator set controls
and instruments are described in tables 2-1 through 2-4
and illustrated in figures 2-1 through 2-4.
NORMAL OPERATING CONDITIONS WITHOUT
HOUSING KIT INSTALLED. The following paragraphs
illustrations. Preparation for starting (figure 2-5), starting
instructions (figure 2-6), stopping instructions (figure 2-
7), and operating instructions for a single generator unit
(figure 2-8). See par. 2-9 for operation with housing kit
Preparation for Starting. Instructions to be
followed when preparing to start the engine generator
set are shown in figure 2-5. Preventive maintenance
procedures to be performed before operation are
provided in table 3-2.
Starting. After performing the preparation
for starting procedure, start the engine generator set as
shown in figure 2-6. If the engine will not start, or if any
other abnormality is observed, notify higher level
Preventive maintenance procedures to be performed
after equipment operation are provided in table 3-2.
Stopping by Safety Devices. The generator
set is equipped with safety device electrical circuits that
automatically stop the engine and simultaneously open
the main AC circuit breaker in the case of: (1) high
coolant temperature, (2) low oil pressure, (3) engine
overspeed, (4) overvoltage, (5) no fuel, or (6) high oil
temperature. A short circuit, overload, or reverse power
protective relay will automatically open the main AC
circuit breaker but will not stop the engine. Undervoltage
relay protective circuit will similarly open the main AC
circuit breaker but will also not stop the engine. A
specific fault indicator (five for the engine and five for
the generator, figure 2-2) will light when any of these
abnormal conditions occur. Once the generator set has
been stopped due to the action of one of these safety
devices, the problem must be corrected before the
generator set is placed back in operation.
Emergency Stopping. To stop the generator
set in an emergency, open the 24V DC CONTROL
CIRCUIT BREAKER (figure 2-7) or EMERGENCY
SHUT DOWN switch (figure 2-3).
