ARMY TM 9-6115-604-12 NAVY NAVFAC P-8-633-12 STEP 3. ON-LINE SET SET MASTER SWITCH TO START AND RELEASE TO RUN. (THE ENGINE WILL AUTOMATICALLYCRANK FOR 15 SECONDS AND REST FOR 15 SECONDS UNTIL THE ENGINE HAS STARTED, FOR A TOTAL OF FOUR CRANK CYCLES ). STEP 4. ON-LINE SET ADJUST FREQ ADJ RHEOSTAT FOR A FREQUENCY METER READING OF 50 HERTZ OR 60 HERTZ, AS APPLICABLE. STEP 5. ON-LINE SET SET GEN/BUS VOLTMETER SWITCH TO GEN 3-1. STEP 6. ON-LINE SET ADJUST VOLT ADJ RHEOSTAT FOR AN AC KILOVOLTS READING OF 4 16 KILOVOLTS (FOR 60 HERTZ OPERATION) OR 3 8 KILOVOLTS (FOR 50 HERTZ OPERATION). STEP 7. ON-LINE SET- SET GEN/BUS VOLTMETER SWITCH TO GEN 2-3, THEN GEN 1-2. VERIFY THAT AC KILOVOLTS READING IS THE SAME AT ALL THREE SETTINGS. STEP 8. ON-LINE SET SET PARALLEL SWITCH TO SINGLE SET. SINGLE SET INDICATOR WILL LIGHT. STEP 9. ON-LINE SET SET BREAKER CONTROL SWITCH TO CLOSE. CLOSED INDICATOR WILL LIGHT. STEP 10. ON-LINE SET SET PARALLEL SWITCH TO PARALLEL. PARALLEL INDICATOR WILL LIGHT. STEP 11. INCOMING SET SET MASTER SWITCH TO START AND RELEASE TO RUN (THE ENGINE WILL AUTOMATICALLY CRANK FOR 15 SECONDS AND REST FOR 15 SECONDS UNTIL THE ENGINE HAS STARTED, FOR A TOTAL OF FOUR CRANK CYCLES ) STEP 12. INCOMING SET ADJUST FREQ ADJ RHEOSTAT FOR A FREQUENCY METER READING OF 50 HERTZ OR 60 HERTZ, AS APPLICABLE. STEP 13. INCOMING SET: SET GEN/BUS VOLTMETER SWITCH TO GEN 3-1. STEP 14. INCOMING SET: ADJUST VOLT ADJ RHEOSTAT FOR AN AC KILOVOLTS READING OF 4 16 KILOVOLTS (FOR 60 HERTZ OPERATION) OR 3 8 KILOVOLTS (FOR 50 HERTZ OPERATION). STEP 15 INCOMING SET: SET GEN/BUS VOLTMETER SWITCH TO GEN 2-3, THEN GEN 1-2. VERIFY THAT AC KILOVOLTS READING IS THE SAME AT ALL THREE SETTINGS. STEP 16. INCOMING SET: CHECK PHASE SEQUENCE USING PHASE SEQ. SEL. SW AND 1-2 3 AND 3-2-1 INDICATOR LIGHTS. ENSURE THAT SETS ARE IN PHASE BEFORE PROCEEDING. STEP 17 INCOMING SET: SET PARALLEL SWITCH TO PARALLEL. PARALLEL INDICATOR WILL LIGHT. STEP 18 INCOMING SET: SET SYNCHROSCOPE SWITCH TO ON SYNCHROSCOPE WILL BEGIN ROTATING AND SYNCHRONIZING LIGHTS WILL BEGIN BLINKING. STEP 19. INCOMING SET ADJUST FREQ ADJ RHEOSTAT UNTIL SYNCHRONIZING LIGHTS ARE BLINKING VERY SLOWLY AND SYNCHROSCOPE NEEDLE IS ROTATING SLOWLY IN THE CLOCKWISE (EST) DIRECTION. STEP 20 INCOMING SET: ADJUST VOLT ADJ RHEOSTAT USING GEN/BUS VOLTMETER SWITCH AND AC KILOVOLTS METER UNTIL GEN AND BUS VOLTAGES ARE IDENTICAL. STEP 21 INCOMING SET: WHEN SYNCHRONIZING LIGHTS ARE DARK AND SYNCHROSCOPE NEEDLE IS IN 12 O'CLOCK POSITION, SET BREAKER CONTROL SWITCH TO CLOSE. CLOSED INDICATOR WILL LIGHT. STEP 22 INCOMING SET SET SYNCHROSCOPE SWITCH TO OFF; STEP 23 ALL SETS ADJUST VOLT ADJ AND FREQ ADJ RHEOSTATS TO BALANCE THE LOAD ON ALL SETS AS INDICATED BY THE KILOVAR AND AC KILOWATTS METERS ADJUST VOLT ADJ TO EFFECT KILOVARS ADJUST FREQ ADJ TO EFFECT KILOWATTS. STEP 24 IF ADDITIONAL GENERATOR SETS ARE TO BE PARALLELED, REPEAT STEP 11 THROUGH STEP 24, ABOVE, FOR EACH SET. STEP 25 ALL SETS PERIODICALLY (NOT LESS THAN ONCE PER HOUR) MONITOR ENGINE AND GENERATOR INDICATORS TO ENSURE CONTINUED OPERATION. STEP 26 ALL SETS PERFORM DURING OPERATION" PREVENTIVE MAINTENANCE CHECKS AND SERVICES AS SPECIFIED IN Table 3-2. STEP 27 TO STOP ENGINE REFER TO Figure 2-26. Figure 2-25.
