ITF found in Troubleshooting mode with the following issues:

• BS loops opened, problem know: 68224.
• PR vertical correction saturating; to be recovered by the experts.
• SIB1 IP open; likely because of the previous problem.
• SPRB and SWEB vertical correction to be recovered.
• temperature in NE and WE outside the thresholds; to be investigated.

At around 8:00 UTC I recovered SIB1, SPRB and SWEB: in parallel Davide went to the END buildings to adjust the set points of the boilers.

At around 10:00 UTC the SAT team went in CB to work on the BS.

At around 10:30 UTC Paolo recovered the PR suspsension: after that I recovered the aligment of the north cavity and I was able to lock it on the IR.

At around 10:30 UTC Romain started to perform some noise injection on the DET bench.

At around 10:45 UTC the SAT team recovered the BS suspension; after that I manually realigned the WEST cavity and I was able to relock the ITF on the IR restoring the automation.

The BS suspension failed again at around 11:40 UTC;  situation in progress.

Software

BacNet restarted at 10:02 UTC because it was providing flat data.

SNEB loop closed and vertical position with step motors at 10:15 UTC
