I NOTES I. ANALOG GATE CONSISTS OF 2 SOLENOID VENT VALVES IN SERIES TO REDUNDANTLY I NTERLOCK THE AIR L JNE BETWEEN EACH VALVE DIAPHRAM AND ITS ASSOCIATED POSITJONER, THE SOLENOID VALVES ARE DE-ENERGIZED TO VENT, CAUSING THE MA I N FEEDWATER VALVE TO CLOSE IN 7 SECONDS.

2. ALL CI RCUITS IN TH I S SHEET ARE NOT REDUNDANT EXCEPT WHERE INDICATED "REDUNDUNT".

THE REDUNDANT MANUAL RESET CONSISTS OF TWO MOMENTARY CONTROLS ON THE CONTROL BOARD, ONE OF EACH TRAIN.

5. OPEN/S HUT I ND I CAT I ON FOR EACH FEEOWATER CONTROL VALVE IN CONTROL ROOM.

6.

7, FEEDWATER PUMPS ARE TRIPPED BY TRAIN "B" ONLY.

8, FEEDWATER I SO LA T I ON VALVES ARE CLOSED BY TRAIN "A" ONLY.

9. SHEET NUMBERS REFER TO THE REFERENCE NUMBERS BELOW.

10. WHENEVER A PROCESS SIGNAL IS USED FOR CONTROL AND IS DERIVED FROM A PROTEC T ION

CHANNEL, I SOL AT I ON MUST BE PROV I OED.

TH !S DRAWING ILLUSTRATES THE FUNCT !ONAL REQUIREMENTS OF THE REACTOR CONTROL AND PROTECTION SYSTEM.

THIS DRAWING DOES NOT REPRESENT ACTUAL HARDWARE IMPLEMENTATION.

FOR HARDWARE IMPLEMENTATION. REFER TO THE APPLICABLE SCHEMAT I C.

12. BOARD INDICATION IS FROM A DFWCS OUTPUT. ALL OTHER INDICA T IONS ON THIS DRAWING ARE PROV I OED ON THE DFWCS HM!.
