Main machine issues have been resolved and beam restored to 2C and 3C dumplettes. We need BSY2C on at this point to continue setup to Hall B, but the supply was tripping on overcurrent interlock.

Contacted DCP and they said they can guide an operator on how to tweak the overcurrent interlock which only requires adjusting a potentiometer on the supply. No ePAS, ATLis, equipment specific training, or PPE is required for this task.

One operator is currently out in the field with DC Power on-call working on this.
