EndY ETMY Yend HEPI Pumps off since 12 August
This last occurred at EndY 5 Aug but it wasn't restarted until 11 August. So barely 24 hours later it dropped out again. 14 August was the power outage and it appears no restart attempt was made at EndY. EndX is running at this time. Borja is taking data at the moment and asks the optic not be disturbed. This restart will require a trip to the EndY MR.
Dave just reminded me of the power glitch at 2355utc 12 August and this is when the pump stopped. I can see that EndX also saw the glitch but appears to ride it out and was quickly restarted after the power outage. All assumptions as I've found no logs about HEPI restarts before or after the power outage.
