[BLAST_SHIFTS] BLAST PS

Blast Power Supply tripped once again at ~18:30. Lights on front of
power supply indicate DCCT and rectifier water faults. Not sure if both
failed or cross talk took out on or the other. I think the PS voltage
was getting high, >225 V, and this may be correlated with trips. Also
note trips occurred w/ change in the weather and daytime operation.

We reset it and have had no further trips so far tonight. If it trips
again operations should access South Hall to record fault status. If
again indicates water, ops should notify Rich Cap.. If DCCT fault TZ or
RJA shoukd be notified. Kelsey also needs to be informed if supply
continues to trip.
