PSL Weekly FAMIS Tasks (FAMIS 3663 & 8435)
This morning I completed the weekly PSL FAMIS tasks.
HPO Pump Diode Current Adjust (FAMIS 8435)
With the ISS OFF, I increased the operating current of the HPO pump diode boxes; DB1 increased by 0.2 A, DB2 DB3, and DB4 all increased by 0.1 A. The changes are summarized in the below table and a screenshot of the PSL Beckhoff main screen is attached for future reference.
| Operating Current (A) | ||
| Old | New | |
| DB1 | 49.4 | 49.6 |
| DB2 | 52.4 | 52.5 |
| DB3 | 52.4 | 52.5 |
| DB4 | 52.4 | 52.5 |
I did not adjust the DB operating temperatures. The HPO is now outputting ~155.1 W, the ISS is still OFF (will remain OFF until I finish the PMC alignment tweak). This completes FAMIS 8435.
PSL Power Watchdog Reset (FAMIS 3663)
I reset both PSL power watchdogs at 16:00 UTC (9:00 PDT). This completes FAMIS 3663.
