PSL Weekly FAMIS Tasks (FAMIS 4022 & 8451)
This morning I completed the weekly PSL FAMIS tasks.
HPO Pump Diode Current Adjust (FAMIS 8451)
With the ISS OFF, I adjusted the HPO pump diode operating currents. The changes are summarized in the below table; a screenshot of the PSL Beckhoff main screen is attached for future reference.
| Operating Current (A) | ||
| Old | New | |
| DB1 | 53.0 | 53.2 |
| DB2 | 54.8 | 55.0 |
| DB3 | 54.8 | 55.0 |
| DB4 | 54.8 | 55.0 |
I did not adjust the operating temperatures of the diode boxes. The HPO is now outputting 155.4 W and the ISS is back ON. This completes FAMIS 8451.
PSL Power Watchdog Reset (FAMIS 4022)
I reset both PSL power watchdogs at 18:35 UTC (10:35 PST). This completes FAMIS 4022.
