suggested form, of course, and there may be many other forms at your generating station to keep records on.
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 manufacturer's 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 generator.
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:
WARNING 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 manufacturer's 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 section.
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 RUN.
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.
b. 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.Continue Reading
