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).
