d. Refer to paragraph 2-5.3.1

TM 9-6115-662-13&P d. Refer to paragraph 2-5.3.1 (steps c. through i.), to start a generator set and bring it on line. e. On operating generator set (generator set 1) position UNIT-PARALLEL switch (16) to PARALLEL. f. Start generator set 2 and adjust voltage and frequency to match generator set 1. g. At switch box, set generator set 2 ON-OFF switch (3 or 6) to ON (Switch box STATUS & ON-LINE lights for both generators should be lit). h. At generator set 2 control panel: (1) Set UNIT-PARALLEL switch (16) to PARALLEL. Both SYNCHRONIZING LIGHTS (12) should be going bright to dark together. CAUTION If SYNCHRONIZING LIGHTS on generator set 2 do not go bright and dark in unison, the phasing is wrong. Shut down generator sets and check that load cables are connected properly. Failure to observe this caution can result in damage to generator sets. (2) Increase frequency until SYNCHRONIZING LIGHTS (12) blink together one or more times per second. (3) Decrease frequency until SYNCHRONIZING LIGHTS (12) blink together once every 3-4 seconds. CAUTION Check that load contactor at load is open before attempting to place generators on line. Failure to observe this caution can result in damage to generator sets. (4) When both SYNCHRONIZING LIGHTS (12) are dark, position and hold AC CIRCUIT INTER- RUPTER switch (13) of generator set 2 in the CLOSED position until indicator light (14) goes out. SYNCHRONIZING LIGHTS (12) should go out (both generators are now operating in parallel with no load). i. Rotate FREQUENCY adjust potentiometer (15) of generator set 1 until percent power meter (10) reads approximately “O”. j. Rotate VOLTAGE adjust potentiometer (11) of generator set 1 until AC AMPERES meter (9) reads approximately “O”. k. Close the load contactor at the load. 2-38
