STARTING THE GENERATOR SET

ARMY TM 9-6115-464-12 AIR FORCE TO 35C2-3-445-1 NAVY NAVFAC P-8-624-12 2-6 STARTING THE GENERATOR SET. If the generator set is to be operated for the first time, unit maintenance must be notified to perform service upon receipt. Equipment damage could result if caution is not observed. a. Refer to paragraph 2-4 and check that the installation instructions have been properly accomplished. b. Refer to paragraph 2-5 and check that the reconnection board is in the position corresponding to the voltage requirements of the Ioad and that the frequency selector switch is in the correct position. (1) (2) (3) (4) (5) (6) (7) (8) (9) Refer to Table 2-2 and perform the BEFORE OPERATION checks and services. If an auxiliary fuel supply is used, position the fuel selector valve handle in the AUXILIARY position. If the generator set tank is to be used, position the handle in the SET TANK position. NOTE If acoustic suppression kit is installed, open both inlet and discharge doors on roof prior to starling. Power cables must be routed through opening in rear panel assembly. Close all access doors with the exception of those for the generator air vent and the control cubicle. Lock the generator set air inlet doors in the open position. Check that the DC circuit breaker is in the closed position. If the generator set fuel tank is being used, place the START-RUN-HOP switch in the RUN position and the BATTLE SHORT switch in the ON position. Check the fuel level gauge for sufcient fuel indication. NOTE On precise generator sets the low oil pressure, under voltage, and under frequency indicator lights will illuminate. On utility generator sets, the low oil pressure indicator Iight will illuminate. Leave the START-RUN-STOP switch in the RUN position and the BATTLE SHORT switch in the ON position a suffcient length of time to ensure that the day tank assembly contains enough fuel for starting. Place the BATTLE SHORT switch in the OFF position. Depress the fault Iocation indicator, TEST OR RESET switch and check that all fault location indicator Iights illuminate. On tactical utility generator sets, pull the manual speed control all the way out, then push approximately halfway in. c. Starting. Refer to Figure 2-8 for starting instructions. If acoustic suppression kit is installed, control ac- cess door must be opened for controls access. After starting, close control access door. d. Single Unit Operation. (1) Rotate the VOLTS-AMPS transfer switch to each phase position while observing the ac ammeter. If more than rated load is indicated in any phase, reduce the load. (2) Check the kilowatt meter indication. If the indication is more than 100 percent rated load, reduce the load. NOTE If load cannot be reduced, obtain another generator set and proceed to parallel operation. 2-10
