5) Verifying that on a Safety Injection Actuation test signal, without loss of offsite power, the diesel generator starts on the auto start signal and operates on standby for greater than or equal to 5 minutes. The generator voltage and frequency shall be 6900 1 690 volts and 60 1 1.2 Hz within 10 seconds after the auto-start signal; the steady state generator voltage and frequency shall be maintained within these limits during this test: {
