Problem Reports
PR NumberTimesTime LostDescriptionResponse
452708:17-08:18, 09:04-09:0400:01Failed trajectory, structure states that it stopped at the wrong position. Worked after resending target.
452603:23-04:0100:38Failed to acquire trajectory slewing to target. Last error: MSG H6 Velocity Fault. Reset the fault, hit abort tracker twice and resent the target. Got a MSG Rho Following Error Fault trying to go to the target again. Tracker not skewed. Sending the target failed again with a torque limit sensor fault.Had to walk the tracker by 10 mm in slow slew since it was the LX slew torque limiter. This fixed the problem.
432104:07-05:2501:18Failed to adjust trajectory for current tracker position. Restarted servers, dspace, control desk, and then reinitialized. This solved the problems.
169604:12-04:12, 10:29-10:2900:00Took out 32-1 for LTRSE. Temp Ext: 19.1 R.H: 71.4 Took out 51-4 for LTRSE. Temp Ext: 16.6 R.H: 86.8
415005:28-05:3300:05Fails to start the pipeline for the ACAM. Gives the error StartPipeline caught an exception. Led on TCS gui for pas server still green. Checked and no cameras will start pipeline.Restarted the pas server.
450106:28-06:4500:17Failed trajectory due to a Torque limit fault. Fixed the usual way. Got Lx following error fault when target resent. I reinitialized and sent the target again and got a MSG H5 Following Error Fault. Cleared the H5 following error fault and then sent the target again which succeeded.
452510:54-10:5400:00Bottom left third of mirror out again. Same segments as yesterday. By the time I got to writing up the PR it seems to have fixed itself.
443206:50-06:5200:02PAS server very slow, On the acam it was taking a minute to display a 3 second image.restarted pas server.
