The VME crate for the LVEA Y arm vacuum controls failed last night. From initial investigation it looks like the power supply died. I have swapped out the crate with a different one and re-installed all of the cards and cables. Cyrus assisted in getting it back up and running. See his report.
Richard,
Can we get a time of the failure? That will give us a good number on the LN2 boiloff rate.
thanks
h0vely failed at 01:26 UTC Friday, 18:26 Thursday local time. I'm investigating why no emails were sent to cell phones.
The DAQ EDCU did not reconnect to this IOC, I restarted the DAQ at 11:59 this morning to force a reconnection.
