EVE Operator Summary

Observatory Mode taken from Unknown to Commissioning

Some recovery from Maintenance Thurs (Roll Modes and checks of violin modes).  Rest of the evening consisted of Commissioning work (Jeff

Worked on damping out Roll Modes of ITMx (with Sheila's tutorial).  Spent about ~30min (started at 4:58pm)

Received some Test Mass Coil WD Verbal Alarms (i.e. ETMX RMS ['LR'] WD has tripped).  And this was a first for me.  Kissel pointed me toward how to untrip these (Jeff said this WD is for the Test Mass penultimate masses (which is L2?).  For L2, the WD Trips are located on the right side of the SUS screen (RMS WD RESET).  To clear, put in a 1.0 for the UL & then take it back to 0.0.  This seems to take care of it for all the coils!  Kissel was concerned that these sort of WD trips could be a sign for violin modes ringing up.

SIDE NOTE:  The operator electric table apparently couldn't take my weight & failed.  Please do not use this table until it is repaired.

Please do not sit on the electric table at the operator's station.  It is not intended to support your weight.

Bubba repaired the table this morning.
