Hi everyone,
update: the NMR community nailed it, it was indeed the power supply. Thank
you all for the rapid and helpful responses.
Confirmed board damage in the AQS PSU, it's fried. Probably found it as it
was dying and power cycling finished it off. One of our other magnets is being
completely upgraded this summer so we had already planned to swap this console
for an AVANCE III. We'll see if the department wants to put more resources into
it to bridge the couple months until then. If not, it was a 20+ year instrument
that had a good run.
Kind regards,
Luke

Hi Everyone,
Our Avance console had a heart attack this morning and I'm hoping the
collective knows a way to resuscitate it.
The first user of the day couldn't tune or collect spectra. There weren't
any hung processes, and the problem persisted through software and computer
restarts. Error messages pointed to multiple boards on the AQS rack (RCU,
SGU1, others) and the instrument has a history of communication issues. I
begrudgingly power cycled the console...
...and now there's no activity from a whole side of the AQS rack. CCU10,
TCU3, FCU3, GCU, RCU1/2 all dormant. pictures attached.
Any pointers would be much appreciated!
Kind regards,
Luke
