FLAO #1 failures log

Timestamp (UTC) Severity System Type Device Description Notes
20150420 050000 apprx High WFS HW BCU47 Reset Recovered without any intervention after about 5 minutes.
Insensitive to rotation (from 180 to 300 degrees instr. rotator)
20150420 (all day)   general HW   Misaligned PSF PSF was found at about Y=-80 mm, even if the spot was centered on the N30 camera. We did not try to re-home the stage.
20150420 161545   WFS SW Wfs arbitrator Acquire ref command stuck Acquire ref command stopped after logging "Starting source acquisition" without reporing any error. Needed to restart the WFS arbitrator.
20150420 163247   WFS SW Wfs arbitrator Autogain command stuck Autogain command stopped after logging "Starting gain optimization procedure". No gain commands sent to the adsec. Needed to restart the WFS arbitrator.
20150421 155500   WFS SW Wfs arbitrator Pupil rerotator not moving. After an adsec_stop/start (for other reasons), the pupil rerotator was not following the derotator position anymore. A restart of the WFS arbitrator was needed. This bug has been known for a long time.
Low WFS   Slope computer Commands not received for some seconds For about 5-6 seconds, the slope computer controller reported errors in sending commands to the BCU. Not clear whether it was software or hardware. This caused the preset to fail. Just repeating the preset was enough to make things work.
20150423 High WFS HW BCU47 BCU47 Off line
