PSL Weekly FAMIS Tasks (FAMIS 3672 & 8444)
This morning I completed the weekly PSL FAMIS tasks.
HPO Pump Diode Current Adjust (FAMIS 8444)
With the ISS OFF I adjusted the operating currents of the HPO pump diode boxes. 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 | 50.7 | 50.9 |
| DB2 | 53.1 | 53.3 |
| DB3 | 53.1 | 53.3 |
| DB4 | 53.1 | 53.3 |
I did not adjust the operating temperatures of the DBs. The HPO is now outputting 154.4 W and the ISS is back ON. This completes FAMIS 8444.
PSL Power Watchdog Reset (FAMIS 3672)
Both PSL power watchdogs were reset at 15:49 UTC (8:49 PDT). This completes FAMIS 3672.
