I performed the weekly PSL FAMIS tasks during today's maintenance window.
HPO Pump Diode Operating Current Adjustment (FAMIS 8429)
All HPO pump diode operating currents were increased by 0.2 A (this was done with the ISS OFF). The first attachment shows the diode box decay over the last 7 days, and the second shows the PSL Beckhoff main screen after the operating current adjustment was complete (included for future reference). The below table summarizes the operating current change:
| Operating Current (A) | ||
| Old | New | |
| DB1 | 48.7 | 48.9 |
| DB2 | 51.6 | 51.8 |
| DB3 | 51.6 | 51.8 |
| DB4 | 51.6 | 51.8 |
I did not adjust the operating temperatures of the diode boxes. The ISS has been turned back ON and the PSL is now outputting 157.5 W. This completes FAMIS 8429.
Power Watchdog Reset
I reset both PSL power watchdogs at 16:22 UTC (9:22 PDT). This completes FAMIS 3657.
