Right now the SSA for HL1 cavities 3 & 7 is off on purpose. I was surprised that the display says NRF rather than SSA for these. It's looking at FaultSummary.SEVR, which is green. Would :AlarmSummary.SEVR be better? It's currently minor because the SSA is off. I assume the code needed to support reading the Status Message for "SSA Off" is eye-rolling-ly annoying.
Also, if I click on the SSA button on the display that comes up when you click an individual cavity, I get an edm error msgbox: Error loading file: /usr/local/lcls/tools/edm/display/llrf/rf_srf_ssa_{cm_OR_hl}.edl
I assume this is a placeholder while we all wish the SSA plumbing had been done in a more sane manner for the 3.9s...
And while I was typing this they ran auto-setup and recovered the SSAs & cavities.
