Ring heater drivers back on temporarily
After speaking with Chandra, I've turned the RH drivers back on to do a test on the HWSY alignment right now.
I'm going to turn them off again in about 40 minutes.
The ring heater drivers are now switched off.
Until we open gate valves 1 & 2, we don't have HV interlock protection on the vertex, so we shouldn't leave HVs on when not needed. Thanks!
