suggested form, of course, and there may be many other
forms at your generating station to keep records on.
OPERATING PROCEDURES FOR SINGLE
The following operating procedures are general
procedures for operating a single generator unit. Some
procedures will vary with different types of generators.
Study carefully the recommendations in the
manufacturers manual for the generator you are to
operate. Learn about the capabilities and limitations of
your machine(s). In the event of a problem, you will
know what action is required to lessen the effects of the
problem. You or your senior should make a checklist of
operating procedures from the manual and post it near
The steps below will cover starting and operating a
typical diesel-driven generator set. (This set uses a dc-
powered motor for starting the diesel engine.) These
steps will also cover applying an electrical load.
Starting the Generator Set
Proceed as follows to start the typical generator set:
Do not operate the generator set unless it
has been properly grounded. Electrical faults
(such as leakage paths) in the generator set,
feeder lines, or load equipment can cause injury
or death by electrocution.
Before operating the set for the first time, ensure
that service procedures were performed upon its receipt
according to the manufacturers literature. See also that
all preventive maintenance checks have been
performed. The voltage change board must be adjusted
for the required voltage (fig. 3-11).
1. Open the CONTROL CUBICLE and AIR
INTAKE DOORS (fig. 3-15). Close the HOUSING
PANEL (ACCESS) DOORS,
2. Set the FUEL TRANSFER VALVE (fig.3-15)
to the desired source of fuel, preferably the auxiliary
tank, if it is connected.
NOTE: Refer to figure 3-19 for the CONTROL
CUBICLE, FAULT INDICATOR PANEL, DC
CONTROL CIRCUIT BREAKER, and ENGINE
MANUAL SPEED CONTROL. Notice that the control
cubicle is divided into an engine section and a generator
3. Set the PARALLEL OPERATION-SINGLE
UNIT OPERATION select switch (located in the
GENERATOR section of the CONTROL CUBICLE)
to SINGLE UNIT OPERATION.
4. Set the VOLTAGE ADJUST-INCREASE
control to the lower half of the adjustment range.
5. Depress the DC CONTROL CIRCUIT
BREAKER (located to the lower right of the
CONTROL CUBICLE) to ON.
6. Set the START-STOP-RUN switch (located in
the ENGINE section of the CONTROL CUBICLE) to
7. Set and hold the TEST or RESET switch (on
the FAULT INDICATOR PANEL) in the UP position.
Each fault indicator light should be on Check and
replace defective lamps or fuses.
8. Allow the TEST or RESET switch to return to
the mid-position. Each fault indicator light, with the
exception of the LOW OIL PRESSURE light, should go
out. When the engine has started, the LOW OIL
PRESSURE light should also go out.
NOTE: If the NO FUEL light stays lit, refill the set
or auxiliary tank. Position the BATTLE SHORT switch
(CONTROL CUBICLE) to ON (the fuel pump will run
to fill the day tank). Set the TEST or RESET switch to
the UP position and then release it; the NO FUEL light
should go out when the switch handle is released.
9. Set the CKT BRK CLOSE-OPEN switch
(CONTROL CUBICLE) to OPEN.
10. Push and release the AIR CLEANER
CONDITION indicator, BATTLE SHORT indicator,
and CKTBRK indicator. Each indicator light should go
on as the indicator is pushed and go out when the
indicator is released.
a. If the AIR CLEANER CONDITION
indicator remains lit, the air cleaner must be serviced.
If the CKT BRK indicator remains on after
you set the CKT BRK switch to OPEN, you cannot
continue the procedure. The circuit breaker must
function properly. The generator cannot be used until
the problem is corrected.
11. Depress the lock button on the ENGINE
MANUAL SPEED CONTROL (located below the DC
CONTROL CIRCUIT BREAKER), and set the control.
