AS A GENERAL GUIDE, THE EXTENT OF INSTUMENTATION SHOWN ON THE P&ID SHOULD BE SUFFICIENT TO PERMIT
THE OBSERVER TO IDENTIFY THE MAIN COMPONENTS AND THE FINAL READOUT CONTROL AND/OR ALARM ACTION
AND TO UNDERSTAND THE FULL FUNCTION OF THE INSTRUMENT SYSTEM. IDENTIFICATION OF ALL COMPONENTS
AND THE FULL SCHEMATIC RELATIONSHIP ARE SHOWN ON THE INSTRUMENT HARD WIRED LOOP DWGS.
START/STOP AND H-O-A HAND SWITCHES FOR PUMP "A" WILL HAVE A
SEQUENTIAL NUMBER. A DIFFERENT SEQUENTIAL NUMBER IS USED FOR PUMP "B".
THE DCS SOFT DEVICE BLOCK TAG WILL NOT HAVE A SUFFIX (I.E. HS-110) THE
LOCAL HAND SWITCHES FOR H-O-A AND LOCAL START/STOP WILL HAVE SUFFIX
STARTING WITH A (I.E. HS-110A). COMMON HAND SWITCH FOR BOTH PUMPS
(I.E. SELECTOR SWITCH) WILL HAVE ITS OWN SEQUENTIAL NUMBER.
ALL CONTROLLERS COMING INTO DCS DO NOT NEED TO BE MARKED AS AN IC OR
RC AS I AND R ARE IMPLICIT FOR EVERY POINT.
ALARM PRESENTATION (MINIMIZE NUMBER OF BALLOONS)
THE OPERATOR HAS THE ABILITY TO SET AN H OR L FOR ANY POINT.
THESE OPERATOR ALERTS WILL NOT BE SHOWN ON P&ID ALARMS UNDER ENGINEERING CHANGE
