ID POSSIBLE CAUSE SETPOINT SIYS653 SDC Loop 1 Isolation Valve Inverter Trouble SIYS654 SDC Loop 2 Isolation Valve Inverter Trouble N/A None FIR TPRIORITY PERAT RA I N Ifthe valve was traveling at the time of the alarm, monitor the valve position indicator (0-100%) and the valve position lights to determine ifthe valve completed travel. The position indicator and lights are located on Panel B02 above the control switches for the following valves:

RC L'OOP 1 S/D CLG-LPSI PMP A SUCT VLV, SIC-UV-653

~ RC LOOP 2 S/D CLG-LPSI PMP B SUCT VLV, SID-UV-654 E ND PRI RITY PERAT RA ION NOTE Response to this condition may affect Technical Specification 3.7.11, in Modes 3.-3, 3.4.1.3 in Mode 4 and 3.4.1.4.1 and 2 in Mode 5.
