Date Time Component Description
11/13/2014 16:31:40 FLEX MEMORY Modify Flex 1, Segment 0, Word 14, Position Mode wavelength, to GPOS -1263 (378nm)
03/21/2013 16:54:30 CHOPPER MOTOR This will call Macro 0010 twenty times. The SBUV motors will be power toggled for a duration of approximately 200 seconds. This CP will also deactivate both macros, then reactivate Macro 004B which monitors for 40 C.
01/24/2013 17:03:13   Turned off the calibration lamp heater
01/16/2013 16:59:10 CHOPPER MOTOR This activates the power toggle, Macro 10, and will leave the SBUV powered, which is the upper temp macro was previously enabled for protection
01/16/2013 16:57:56 CHOPPER MOTOR Switched from previous macro toggling to 4B/4C toggling; 40C turn off with 2 orbit delay before toggle on sequence
01/03/2013 14:13:46 CHOPPER MOTOR Macro changed from 40C and 28C to 40C and 35C in hopes that a power toggle at a higher temperature will revive the chopper motor.
12/21/2012 16:43:47   Setting the wavelength to 252nm short wavelength allows for any subtle movement from the chopper motor to be more easily identified
12/21/2012 16:43:32 GRATING DRIVE Command will set the grating drive to position mode
12/21/2012 16:39:17   This command will open the lamp door
12/21/2012 16:37:45   This will command will stow the diffuser
12/20/2012 18:00:00   Removed all routine SBUV stored commands load activites
12/12/2012 08:07:22 Chopper Motor Chopper Motor stalled and 3 macros are power cycling the motor.

11/12/2008 19:28:09 CALIBRATOR SBUV Calibration Lamp Heater ON
11/12/2008 03:27:45 CHOPPER MOTOR The N18 SBUV Chopper Motor returned to nominal operation at 2008/317-03:27:45 UTC.
11/10/2008 21:36:00   Turn off Calibration Lamp Heaters
11/10/2008 21:36:00   Select grating to position mode
11/10/2008 21:36:00   Program position mode to 252 nm
11/09/2008 06:52:16 CHOPPER MOTOR Chopper Motor Stalled. SBUV Toggling Macro switched from 21C to 24C set point.
11/09/2008 02:35:00 CHOPPER MOTOR At approximately 2008/314-02:35 UTC the Chopper Motor on the NOAA-18 SBUV stalled. The signature was identical to previous occurrences of the motor stall that were observed early this summer.

05/23/2008 16:17:41 CHOPPER MOTOR Telemetry and Science Data indicated the Chopper Motor is halted. Power was still being disipated through the motor and causing it to heat excessively. The motor power was disabled in an attempt to protect the instrument while recovery options are being weighed. Science Data is currently unusable.
05/22/2008 15:55:00 CHOPPER MOTOR On 2008/143 at approximately 15:55 UTC, there was an increase in motor current (VCMTRI) and subsequent temperature (NSBUCMTR) rise on the N18 SBUV Chopper Motor. Coupled to the motor current rise were changes in the Chopper Phase Error (VCPHZERR). The yellow and red high limits to the motor current and motor temperatures began flagging and were spotted on the first contact, at 17:50 UTC, following the increase. Around 20:30 UTC of the same day, the motor current reached a steady state at 0.2 A (ten times nominal levels) and the motor temperature settled near 50 C. Other components in the instrument began showing slow upward trends in telemetry.
