This morning I completed the weekly PSL FAMIS tasks.
HPO Pump Diode Current Adjustment (FAMIS 8434)
With the ISS OFF, I adjusted the HPO pumpd diode operating currents. All currents were increase by 0.1 A; I have attached a screenshot of the PSL Beckhoff main screen for future reference. The changes are summarized in the below table:
Operating Current (A) | ||
Old | New | |
DB1 | 49.3 | 49.4 |
DB2 | 52.3 | 52.4 |
DB3 | 52.3 | 52.4 |
DB4 | 52.3 | 52.4 |
I did not adjust the operating temperatures of the diode boxes. The HPO is now outputting ~154.9 W; the ISS is now turned ON. This completes FAMIS 8434.
PSL Power Watchdog Reset (FAMIS 3662)
I reset both PSL power watchdogs at 15:52 UTC (8:52 PDT). This completes FAMIS 3662.
