Had trouble reengaging Hall C's FFB after a target change. Could not get a "Gain OK" after performing a gain search after Hall C made it to their requested current. After another gain search attempt, the 4 FFB BPMs shown in figure 1 went in to alarm. Didn't catch the actual fault on the live display before they cleared. It wasn't until the final gain search attempt (there were several - see plot) did the BPM wiresums look nominal (all around 10) and gain was found to finally be OK.

Per Daniels email - We are also tracking MYR9R03 temperatures. This dipole has RTDs / thermocouples (PVs in control system of globular form MYR9R03T??). We will watch how it performs over the weekend and Monday and determine if we need to shift target from flushing 4x Arc5 dipoles Tuesday to fewer than 4x Arc5 dipoles AND MYR9R03. Note that MYR9R03 happens to be powered by the Arc5 BoxPS along with the 32 JC dipoles. 
MYR9R03 has been added to ePAS 11320 plant item list. Work is identical to JC flushing, no additional changes required to this ePAS.
Work planned for 7/21.
