After energization, the steady state voltage and frequency of the emergency busses shall be maintained at 4160 i 420 volts and 60 i 1.2 Hz during-
-this test.
c) Verifying that all automatic diesel generator trips, except engine overspeed and generator differential and low lube oil pressure, are automatically bypassed upon loss of voltage on the emergency bus and/or a safety injection test' signal.

The diesel generator shall be loaded to 3875-4075 kw for the 4075 kw diesels and 2700-2850 kw for the 2850 kw diesels.
6.
Verifying that the auto-connected loads to each diesel generator do not exceed the 2000 hour0.0231 days <br />0.556 hours <br />0.00331 weeks <br />7.61e-4 months <br /> rating of 4353 kw l
for the 4075 kw generator and 3100 kw for the 2850 kw generator.
7.
Verifying the diesel generator's capability to:
a) Synchronize with the offsite power source while the generator is loaded with its emergency loads upon a simulated restoration of offsite power, b) Transfer its loads to the offsite power source, and c) Be restored to its standby status.
8.
Verifying that with the diesel generators operating in a test mode (connected to its bus), a simulated safety injection signal overrides the test mode by returning the diesel generator to standby operation.
9.
Verifying that the automatic load sequence timer is l
OPERABLE with each load sequence time within 10% of its required value or 0.5 seconds whichever is greater.

a) 011 Temperature High (OTH) b) Cooiant Temperature High (CTH) c) Coolant Pressure Low (CPL) d) Crankcase Pressure High (CCPH) d.
At least once per 10 years or after any modifications which could affect diesel generator interdependence by starting tile diesel gener ators simultaneously, and verifying that the diesel generators accelerate to at least 900 rpm, for the 2850 kw generator and 514 rpm for the 4075 kw generator, in less than or equal to 12 seconds.
l The diesel generator shall be determined OPERABLE by verifying that e.
the diesel is not out of service nor in an Initial Requalification Program, as defined in Table 4.8-1.
4.8.1.1.3 Reports - All diesel generator failures, valid or non-valid, shall be reported to the Commission pursuant to Specification 6.9.1.
Reports of diesel generator failures shall include the information reconinended in Regulatory Position C.3.b of Regulatory Guide 1.108,- Revision 1, August, 1977.
If the number of failures in the last 100 valid tests (on a per diesel basis) l is greater than or equal to 7, the report shall be suppi :nented to include the additional information recommended in Regulatory Position C.3.b of Regulatory Guide 1.108, Revision 1, August, 1977.
