OM216 alarmed, signal dropped down rapidly and recovered within a couple of minutes. Apparently, this also happened on day shift as well.

It's dropped much more than any other zone since the SL cold box tripped. Insulating vacuum gauge seems not to have worked since the module was installed.

Update: Still Stuck

1 day 14 hours ago
Log Number: 4511497Logbook(s): Entry Makers: schoeneBody: 

Worked with DCP and SWoC this morning to increase the limit on the ZA shunts, allowing us to put more current in RSEP8A and thus MZA8S03. After doing so we increased the current on RSEP8A by 5A, then moved the 8S shunt back and forth to look for the beam on the 8S01 Viewer and 8S BPMs, but no luck. Also monitored IDX rates in the West arc, trying to find a minimum while sweeping the shunt.

The CHL1 Cold Box tripped at ~1345, ending our efforts until the SL RF is recovered.
