Monthly HEPI Pump Trends

Both EX and EY pump pressure have a big glitch on Feb 23 at 21:26 and 22:49 UTC. There were Guardian restarts going on around that time (alog25679 and alog25684). Average HPI-PUMP_L0_CONTROL_VOUT went up by ~10 counts on Feb 16. HPI-PUMP_EY_CONTROL_VOUT abd HPI-PUMP_EY_PS_PRESSI are glitchy and HPI-PUMP_EX_CONTROL_VOUT has been rising slowly. HPI-PUMP_L0_PS1, 2, 3, 4 pressures are flat (they look unreal).
