The Train B 4160V Switchgear will be de-energized and the D-G output breaker will be locked out during the performance of thi s: procedure. - The Train'B Sequencer will receive a U/V signal and will operate the sequencer output relays.
This test will prove that the Sequencer can be manually reset by the U/'s RESET SWITCH or relay K311 if the D-G output breaker does not close.
It will also prove that the Sequencer cannot be reset by the U/V RESET SWITCH or relay K311 while the D-G output breaker is closed and the Sequencer is cycling.

1.0 PURPOSE
This procedure will test the U/V RESET SWITCH and the remote U/V reset relay (K311) installed in Unit One Train B Sequencer. A Sequencer Operability Check along with this procedure will complete the functional test requirements of DCP 88-V3N0070 for Train B. The DG Brkr Fail To Close relay (K317) and the U/V Reset Enable relay (K306) will also be tested in this procedure.
2.0 PRECAUTIONS AND LIMITATIONS:
2.1 This test, once begun, shall be carried through to completion. If the test must be interrupted, then a detailed explanation of the interruption must be entered into the log.
2.2 Operator assistance should be obtained to operate equipment as required.
2.3 Observe all appropriate precautions and limitations in the plant operating procedures for the equipment operated during this test.
2.4 Prior to the start of the test, the Responsible Engineer shall review the Prerequisites and Initial Conditions, Section 4.0.
2.5 All procedural steps may be signed off by the Responsible Engineer, Shift Supervisor, or designated individual.
2.6 All switches and lights are located on the Unit One Train B Sequencer Test Panel unless otherwise stated.
2.7 Train A 4160Vac (1AA02) is meeting the electrical needs of Unit One. Train B 4160Vac (lBA03)
.switchgear will be de-energized during this procedure.
2.8 Alarms generated during performance of this procedure may be reset at the discretion of the Responsible Engineer.
2.9 Relay K311 may be removed to connect and disconnect the temporary power supply.
