following:
5.8.2.1 Prior to turbine trip, VERIFY 3 out of 4 RPS linear drawer level I bistables are reset.
5.8.2.2 To prevent FRV bypass valve motion, PRESS and HOLD both FRV downcomer reset and ramp stop buttons.
5.8.2.3 PRESS red " TRIP" button.
5.S.2.4 OPEN 2-FV-1 as necessary to raise running EHC pump amps to between 45 and 55 amps. (unloaded amps are between 35 and 40 amps) 5.8.3 E the turbine will be restarted within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, PRESS " SPEED SET RPM, CLOSE VALVES" button and OBSERVE light lit.
