EY HEPI trip, VFH panel reset

The ETMY HEPI pump tripped this morning around 14:35 UTC (7:35am PST) potentially from the CS power glitch? I ended up going out to the Yend mech room and reset the VFH panel to reset the HEPI pump controller. The light was still on when I first checked the panel, I pressed the green ON button first which did not fix the issue, I then cycled it off and back on, pressing the red then green button, confirming that the light went off and on which Jim confirmed to have fixed it. Jim then brought back the pressure to 70PSI from  the Beckoff_Pump_Controller medm.

Verified the HEPI Beckhoff electronics are powered by 24V from the VAC-R1 rack. Vacuum rack is on UPS.
