ARMY TM 9-6115-604-12 NAVY NAVFAC P-8-633-12 1 Set FREQ ADJ to mid-range. 2 Open upper cabinet B door. 3 See Figure 2-6 Adjust 50 CYC (8) or 60 CYC (7), as applicable on load sharing panel for FREQUENCY meter (Figure 2-14) reading of 58 to 62 Hz (for 60 Hz operation) or 48 to 52 Hz (for 50 Hz operation), as applicable 4 See Figure 2-6 If unable to obtain required FREQUENCY meter reading, adjust 50 CYC (8) or 60 CYC (7), as applicable, to mid-range, adjust FREQUENCY ADJUST (3) on load sharing panel, for FREQUENCY meter (Figure 2-14) reading anywhere on scale between pegs, then repeat step 3, above. 5 After meeting requirements of step 3, above, close upper cabinet B door and adjust FREQ ADJ rheostat (Figure 2-14) in accordance with Figure 2-14 (b) If VOLT ADJ rheostat (Figure 2-14) cannot be adjusted for AC KILOVOLTS reading of 4 16 kilovolts (for 60 Hz operation) or 3.8 kilovolts (for 50 Hz operation) proceed as follows: 1 Set VOLT ADJ rheostat (Figure 2-14) to mid-range 2 Open upper cabinet B door. 3 Open voltage regulator cover. 4 See Figure 2-10. Adjust RANGE ADJ (2) for an AC KILOVOLTS (Figure 2-14) reading of 4.16 kilovolts or 3 8 kilovolts, as applicable 5 If unable to obtain required AC KILOVOLTS (Figure 2-14) reading because of voltage fluctuation (hunting), check that stability selection links (1, Figure 2-10) are both set to SLOW and that STABILITY ADJ (3) Is set 1/8 turn back from full clockwise position Then repeat step 4, above 6 Close voltage regulator cover 7 Close upper cabinet B door. (11) Perform the following sub-steps If generator set will be used In droop type parallel with other generator set(s). Otherwise, proceed to step (12), below. NOTE Power factor of load must be 0 8 power factor or this procedure Is Invalid. A dc voltmeter will be required (a) Set PARALLEL SWITCH S6 (18, Figure 2-2) to PARALLEL (b) Set FREQ DROOP/ISOCHRONOUS switch S117 (12) to FREQUENCY DROOP Install shorting plug in REACTIVE LOAD receptacle J21, J22, or J23 (see Figure 2-18). (c) Set BREAKER CONTROL switch S4 (20, Figure 2-2) to CLOSE (d) Check reading on POWER FACTOR meter M104 (9). Verify load has 0 8 power factor to 48 6 for 50 Hz operation If not, proceed as follows 1 Open upper cabinet B door 2 Refer to Figure 2-6 Adjust DROOP (4) on load sharing panel for a FREQUENCY meter (3, Figure 2-2) reading of 58 1 to 58 3 Hz for 60 Hz operation or 48.4 to 48.6 Hz for 50 Hz operation 3 Close upper cabinet B door. (f) Set FREQ DROOP/ISOCHRONOUS switch S117 (12) to ISOCHRONOUS (g) Remove shorting plug from REACTIVE LOAD receptacle J21, J22, or J23 (Figure 2-18). 4-17
