Reset 6.2.5 the fuel racks and reset the eng ne at the EMIP, and the i.exciter at EMMSB.
6.2.6 Observe that the .* diesel, generator, auxiliary systems are apparently in good condition by general inspection.
-6.2.7 Verify that SDR and 5A relays are deenergized.
, 6.3 Startup of the Diesel Generator Obtain clearance from the dispatcher to generate 3 MW for 6.3.1 duration of exercise period (at least one hour, preferably
.four hours) into the grid.
If required, prelube the diesel for 1 minute (not required if
~~.6.3.2 , ,, the diesel has been operated within the previous 7 days).
/Start the diesel by depressing the start pushbutton, release 2: 6.3.3 21-when tachometer indicates a minicus of 250 rpm. The " Engine
-s Cranking" light will initially energize, then extinguish at
- 250 rpm; above 250 rpm, the " Engine Running" lignt will energize
.%'.and remain on while the diesel is running.
-Observe that the diesel comes up to an idle speed of 400 rpm;
/6.3.4 monitor engine for normal conditions.
s 6.3.5 Upon receipt of a eport by the Auxiliary Operator that conditions appear normal, raise engine speed to approximately 900 rpm.
Stop increising spead when generator frequency reaches 60 Hz (the governor high speed light may, or may not be, energized).
NOTE: Carefully observe engine and auxiliary systems for
!normal indications both in the control recm and at
.-the diesel.

':.-1303-4.16 Revision 12 06/28/77 , 6.2.6 Slowly increase generator output voltage to line voltage.(Observe that the " Ready to Load" light energi:es).
6.3.7 Turn the synchroscope on and adjust generator speed to produce a slow rotation of the synchscope in the fast direction.
Adjust generator. voltage to match line voltage. Verify that Diesel Generator output voltage is within +50.0 volts and -0.0 volts of 4160 V ES Bus 10 (1E) voltage.
6.3.8 Place the 1A(lB) Diesel Exciter switch in the AUTO position and verify again that Diesel Generator output voltage is within the limits specified in step 6.3.7.
1.If D.G. output voltage is within the above limits continue with step 6.3.9.
2.If D.G. output voltage is not within limits specified in step 6.3.7, return lA (18) Diesel Exciter switch to the MANUAL position, reverify D.G. output voltage is within the above limits, and then continue with step 6.3.9.
6.3.9 After a report by the auxiliary operator that diesel generator conditions are normal, parallel the generator with the bus:
6.3.9.1 When the synchscope approaches the "12 o' clock" positten (at about "5 minutes to 12") moving in the " fast" direction, observe the synchscope indicating lights are off and close the generator output breaker.
6.3.9.2 Irmediately pick up approximately .3 to 1 MW load by going to" raise" on diesel speed control switch to prevent tripping on reverse power. Switch off the synchscope.
