The clouds went in and out with the TSS problems. AO team discovered a problem with the Thin shell Safety System (TSS) that helps the mirror against the wind effects. One crate was not applying any TSS current.
Both Microgate and Arcetri teams at this point turn the system upside down and started bravely to act on the rear of the crates…
The currents setting of the TSS where slightly decreased in order to avoid a DC DC converter to go crazy. After that a cleaning is a must.
The system were restored in the working position.
… and finally verified all good….
At this point we can say good by at our Microgate friends that are going home.
Good bye, see you!
