2-5.3.2 Load Transfer.

TM 9-6115-660-13&P d. e. f. g. h. i. Refer to TM 9-6115-642-10 and: (1) Start one of the generator sets. (2) Use generator set VOLTAGE adjustable rheostat to adjust voltage to required value. (3) Using generator set frequency adjust control, adjust frequency to required value. (4) Set AC CIRCUIT INTERRUPTER switch on the operating generator set to CLOSED position. Check switch box to make sure that GEN SET ON light (8 or 2) is lit for generator set just started. Set switch box ON/OFF switch (6 or 4) below lit GEN SET ON light to ON position. Check that switch box ON light (8 or 2) and ON LINE light (7 or 3) for operating generator set are both lit. The generator set is now supplying power to the connected load. Observe frequency meter and readjust to proper frequency for load if required. Refer to table 2-2 and perform generator set “During” PMCS. 2-5.3.2 Load Transfer. a. For the generator set that is not operating: (1) (2) (3) (4) (5) (6) 2-36 Refer to table 2-2 and perform the “Before” PMCS. Check that switch box ON/OFF switch (6 or 4) is at center position. Check that switch box TRANSFER switch (5) is at bottom position. Refer to TM 9-6115-642-10 and: (a) Start the generator set. (b) Use generator set VOLTAGE adjustable rheostat to adjust voltage to required value. (c) Using generator set frequency adjust control, adjust frequency to required value. (d) Set AC CIRCUIT INTERRUPTER switch to CLOSED position. Check switch box controls and indicators (figure 2-9) to ensure that: (a) GEN SET ON light (8 or 2) and ON LINE light (7 or 3) is lit for generator set that has been supplying electric power to the load. (b) GEN SET ON light (8 or 2) for generator set just started is lit. Move switch box TRANSFER switch (5) in the direction of the arrow. All SYNCHRONIZING lights (1 and 9) should be going from bright to dark at the same time. If SYNCHRONIZING lights do not begin to function, report problem to next higher level of maintenance.
