keyword=TECH Left Q1 trip, odd reset
Left q1 arbitrarily tripped. No disturbances in the cryogenics. Failure
mode: Magnet appeared to be communicating; in "off" mode we could change
the polarity but we couldn't ramp the magnet; Unresetable "Spare
Interlock" and "Max Current Set" flags. Reset everything on the gui and
the green button in the counting house center room to no avail. On a
long shot we reset IOCHA48, and that worked, but we still see the above
flags. These flags are informational only and not among the hardware
interlock faults. We ramped the magnet to the needed current and resumed
operations.
