There are OPS-PRs for this BPM stack regarding Low X and Y SAT alarms, which go in and out. However, I'm making this one for the HW DIS fault that has since popped up for the whole stack. SME suggested the Low SAT alarms are due to radiation damage — I'm assuming this could be related to that as well?

Cavity was dropping to SEL on PLDE faults. Tried a POFF optimization to see if it would help at all, but it didn't seem to. It almost looks like cavity phase was struggling to regulate following a SL gangphase adjustment and it couldn't catch up. I put the SL GP back where it was before my adjustment and tried recovering the cavity normally, this worked. Not confident that the two are entirely related; it could be that the cavity would have recovered normally after that last try regardless.

Observed during the BLA Calibration, the interlock tripped once we hit 46 uA to Hall C. For now, the Hall is requesting 40 uA, so it is not an issue, but if they want 50, this will have to be addressed.

Not sure if this is an I&C thing, but it is my best guess.

Looks like the bypass bit was set but the cavity wasn't actually bypassed, i.e., it wasn't stepped off, improper masking set. It's definitely draining like crazy.
