Description |
|
05/29/2003 | 19:54:00 | GRATING DRIVE | load Flex 0 position mode word with 205, goto position mode, turn off SBUV motors |
|
05/17/2003 | | GRATING DRIVE | SBUV grating drive became stuck at position 205 during end-of-life-testing. |
|
05/08/2003 | 21:37:00 | DIFFUSER | End of life diffuser deployment test. |
|
05/01/2003 | 21:20:00 | FLEX MEMORY | End of life testing. Cycle through all flex memory |
|
04/21/2003 | 15:20:00 | FLEX MEMORY | Select flex memory two. |
|
03/18/2003 | 16:28:00 | FLEX MEMORY | Select flex memory zero. |
|
03/18/2003 | 16:28:00 | FLEX MEMORY | Strobe memory to update |
|
05/02/2002 | | GRATING DRIVE | New memory segment loaded to test position offset. Grating position was sticking and not shifting the position by 6 counts. Commanded back to old memory segment. |
|
03/12/2002 | | GRATING DRIVE | Grating position is off by 6 counts. |
|
03/11/2002 | 16:25:00 | FLEX MEMORY | Select flex memory 1 for grating drive test |
|
03/11/2002 | 16:25:00 | | Strobe command to confirm flex memory switch. |
|
03/01/2002 | | GRATING DRIVE | SBUV/2 grating sensing wavelengths offset |
|
08/27/2001 | | GRATING DRIVE | Change in grating drive behavior. The change is associated with a dramatic jump in the B-pair total column ozone estimates for this instrument. |
|
05/22/2001 | | GRATING DRIVE | Tested SBUV again with TOMS/total wavelengths. Again, the grating drive behaved erratically. Returned to previous operation. |
|
05/21/2001 | | GRATING DRIVE | Tested SBUV with TOMS/total wavelengths. Grating drive behaved erratically. Returned to previous operation. |
|
04/03/2001 | 15:00:00 | GRATING DRIVE | SBUV grating limited operation (-320 to -699) |
|
03/27/2001 | 09:25:00 | GRATING DRIVE | SBUV grating stuck |
|
03/26/2001 | 02:30:00 | GRATING DRIVE | Grating began operating in a limited range. |
|
03/15/2001 | 05:12:00 | GRATING DRIVE | Grating drive began operating nominally |
|
03/14/2001 | 22:48:00 | GRATING DRIVE | Grating began operating in a limited range. |
|
06/16/2000 | 21:30:00 | GRATING DRIVE | Grating drive began operating nominally |
|
06/16/2000 | 14:34:00 | GRATING DRIVE | Grating began operating in a limited range. |
|
05/06/2000 | 17:33:00 | GRATING DRIVE | Grating drive began operating nominally |
|
05/06/2000 | 11:17:00 | GRATING DRIVE | Grating began operating in a limited range. |
|
09/08/1999 | 05:05:00 | GRATING DRIVE | Grating drive began operating nominally |
|
09/08/1999 | 01:46:00 | GRATING DRIVE | Grating began operating in a limited range from -230 to -402. |
|
03/16/1999 | | GRATING DRIVE | Began Giant Step Operations for 5 minutes per day |
|
02/27/1999 | 13:01:00 | GRATING DRIVE | Grating drive began operating nominally |
|
02/27/1999 | 11:26:00 | GRATING DRIVE | Grating motor temperature increase and drive position stuck between -35 to -186 |
|
09/14/1998 | 02:20:00 | GRATING DRIVE | Grating position was stuck at -100. Returned to normal at 7:27UTC |
|
10/16/1994 | | DIFFUSER | SBUV diffuser indicated that it did not go into stow position and the timer times out. |
|
05/07/1990 | | GRATING DRIVE | Sweep mode, grating drive anomlay in both encoders. Marginal effects in solar irradiance data. |
