NOTES/ISSUES/PROBLEMS --------------------- From the 9am status meeting: 3 Supports Completed in the last 24 hours (Total time: 8.2 hours) 2 SSR dumps CAP's / Procedures Run: CAP # | Time | Title / Description / Notes [1543] | 244/1747z | HRC Power Configuration Swap to CEA B on redundant bus Failure of the +/-15V power supply bus on side A of the HRC electronics requires a switch to the electronics on side B. This CAP executes the commands required to switch to side B, powered by the redundant power bus from the spacecraft. In particular, it configures the power to use the redundant +28V bus and turns on the side B +5V LVPS. Additionally, it turns on the side B +/- 15V LVPS and +24V power supplies. Finally, it configures the HRCI in its default configuration, and sends commands to select pre-amp B for PMT#2, and select pre-amp A for PMT#1. The CAP performs cleanup for SCS 135 and 184, and if successful, will turn off the FA6 heater. [1373B] | 244/1932z | PR-377 Rev. A CPE Sun Vector Parameter Patch Update the CPE parameter Sun Vector Solar Array(3) to prevent extended attitude hold condition on the next Safe Mode transition. [1510] | 244/1957z | DSN Outage Deadman Load Part 2 only [1510] | 245/0307z | DSN Outage Deadman Load Part 2 only Radiation: Solar activity is expected to be very low on days one, two, and three (01 Sep, 02 Sep, 03 Sep). MP: On standby until resumption of science. ENG: Pre-approved CAP for EIA Sequencer test. GOT: No issues.
