SURVEII. LANCE REQUIREMENTS auto-start signal; the steady-state generator voltage and frequency shall be maintained within these limits during this test;

6) Simulating a loss-of-offsite power in conjunction with an ESF Actuation test-signal, and: ,

a) Verifying deenergitation of the emergene busses and load i shedding from the emergency busses; I b) Verifying the diesel starts on auto-start signal energizes the emergency buss with permanently conne,cted loads within IT.5 seconds,* energizes the auto-connected emergency (accident) loads through the load sequencer and operates for greater than or equal to 5 minutes while ite generator is loaded with the emergency lohds. After energization, the steady-state voltage and frequency of i the emergency busses shall be maintained at 4160 +170, j 410 volts and 60 + 1.2 Hz during this test; and c) Verifying that all automatic diesel generator trips, except .
