[Jeff K, Stuart A]
Following work yesterday preparing QUAD model updates (see LHO aLOG entry 14645), we convened early this morning to rebuild, install and restart models.
A detailed log of our activities follows:-
- Bring down the IMC to DOWN state via Guardian (no change to LSC model)
- Bring down QUADs to SAFE state via Guardian
- Bring down SEI to OFFLINE state via Guardian
- Capture new safe BURT snapshots for h1lsc, h1susetmx, h1susetmy, h1susitmx and h1susitmx
- Made all QUADs
- Installed all QUADs
- Restarted all QUADs
- Svn-up updated QUAD MEDM screens
- Untripped all Watchdogs
- Restore QUAD alignments
- Restore SEIs to FULLY_ISOLATED via Guardian
- Restore IMC to LOCKED via Guardian
- DAQ process restart at 14:29 (UTC)
- Update other SUS MEDM screens (see LLO aLOG entry 15004)
- Cleaned errant IPC issues with diag reset on GDS TP screen
- Committed new safe BURT snapshots to svn
Summary of benefits:
This now makes damping of violin, bounce and roll modes possible via the the L2 (PUM) stage of all QUADs using DARM error. Other benefits include: ESD linearization, providing infrastructure for remote ESD activation and deactivation. Also, old Guardian infrastructure has been removed from the model and MEDM screen, with new Guardian embedded mini control-panel replacing them in the QUAD Overview MEDM screen (as well as for other Suspensions too)
This closes-out WP#4915.
