5–Linac 4 Dump Control System By C. Maglioni

5–Linac 4 Dump Control System All measurements but FS may fall into the following classification: Acceptable (A): the reading is nominal or within the pre-established acceptable ranges Non-acceptable (NA): the reading is out of the acceptable ranges No-reading (NR): indicate the absence of signal Flow Switch FS is only 0=off / 1=on Flow reading is the driving parameter above all (AF and FS) AF and FS are used in parallel as redundancy and sort of crosscheck. They are supposed to “agree”. If not  DT and Dp become the driving parameters but one of both AF and FS has to be repaired The no-reading signal (NR) is indicative of an instrumentation issue  intervention may have or have to be done (depending on which is the instrument affected) to fix it
