Hi Tyler,

The heartbeat stopped around 1am: https://logbooks.jlab.org/entry/4415043

All Sector 4 N2 volume PVs are frozen. The frozen values look normal.

Can you take a look when you get this message? Meanwhile the shift crew is calling engineering on-call (following the alarm guidance).

Thanks,
Chris
