We had an unexpected power shutdown for 5 sec at ~ 9:15 AM.

Chiara had to be powered up and am in the process of getting everything else back up again.

Steve checked the vacuum and everything looks fine with the vacuum system.

PSL Innolight laser and the 3 units of IFO air conditions turned on.

The vacuum system reaction to losing power: V1 closed and Maglev shut down. Maglev is running on 220VAC so it is not connected to VAC-UPS.  V1 interlock was triggered by Maglev "failure" message.

Maglev was reset and started. After Chiara was turned on manually I could bring up the vac control screen through Nodus and opened V1

"Vacuum Normal" valve configuration was recovered instantly.

 

Chiara needs UPS 

It is arriving Thursday

 EricQ and Steve,

Steve preset the vacuum for safe-reboot mode with C1vac1 and C1vac2 running normal: closed valves as shown, stopped Maglev & disconnected valves V1 plus valves with moving labels.

(The position indicator of the valves changes to " moving " when its cable disconnected )

Eric shut down Chiara, installed APC's UPS Pro 1000 and restarted it.

All went well. Nothing unexpected happened. So we can conclude that the vacuum system with running C1vac1 and C1vac2 is not effected by Chiara's losing AC power.
