Virgo Runs (O3)Gherardini - 15:02 Tuesday 14 May 2019 (45883)
Print this reportOperator report - morning shift 14/5This morning I found the ITF trying to relock, It unlocked at LOW_NOISE_3 state due to the full-bandwidth BS AA, I tried to lock keeping it in drift control and it worked at the first attempt.
List of activities done during the maintenance time:
- grass cutting around central building (Baldocchi) - standard vacuum refill (Macchia) - cleaning in the experimental areas (Ciardelli) - north end building tiltmeter activity (De Rosa) - calibration procedure test (Estevez #45884) - check and refill of TCS CO2 chillers (Gherardini) - injection BPC correction reduction (Gosselin, Pillant) - det lab loudspeaker installation (Menendez #45885) - Mod cleaner air conditioning chillers maintenance (Soldani) - north input cryotrap scaffolding installation (Bazzi) - WI DAS OUT calibration(Nardecchia #45886)
maintenance concluded at 10:19 UTC, back in Science Mode at 11:09UTC.
-ISC the ITF is locked with the BS AA in drift control, the AA in full-bandwidth is still disabled also in the automation.
-ENV magnetic injection started at 5:41UTC, stopped at 6:17UTC because of ITF unlock (ISYS unlock)
-SBE because of the activity on the detection lab the SBD2 lost the control; I open/close the controls at 8:18UTC to recover the standard state.
-SAT the DMS is complaining about "PDU_Status_Incorrect" (SAT..NE_PDU_SOCKET3 = 0), is someone using this socket fro this morning?
