We are having issues in engaging ASC for full IFO. CHARD yaw starts off about -12000 each time we get there and we have to bring it in manually. After manually zeroing it and engaging a few seconds later we lose lock. So we are doing an initial alignment.
This last lockloss we were having the UL PUM coil watchdog trip on ITMX, the other quadrants seem fine. The violin damping channel H1:SUS-ITMX_L2_DAMP_OUT_P_MON is ringing up and looks to be causing this issue. Georgia's suspects mode 12.
We skipped ENGAGE_RF_VIOLINS, it lasted a bit longer but we still lost lock still during engaging ASC, not sure why.
The "ESD X driver is off" warning keeps repeatedly flashing up around CARM offset reduction and beyond, which is putting us all on edge.
We will leave it trying to lock, we're all going home.
I need to change the ESD test on DIAG_MAIN. I'll have a look at it shortly, but in the mean time note that it is only real if it stays up.
