PSL Weekly FAMIS Tasks (FAMIS 3665 & 8437)
This morning I completed the weekly PSL FAMIS tasks.
HPO Diode Current Adjustment (FAMIS 8437)
With the ISS turned OFF, I adjusted the operating current of the HPO pump diode boxes. DB1 increased by 0.2A and no change on DB2, DB3, and DB4. The changes are summarized in the below table; I also attached a screenshot of the PSL Beckhoff main screen for future reference.
| Operating Current (A) | ||
| Old | New | |
| DB1 | 49.8 | 50.0 |
| DB2 | 52.7 | 52.7 |
| DB3 | 52.7 | 52.7 |
| DB4 | 52.7 | 52.7 |
I also adjusted the operating temperatures of the DBs; changes summarized in the below table:
| DB1 | DB2 | DB3 | DB4 | |||||
| Old | New | Old | New | Old | New | Old | New | |
| D1 | 28.5 | 28.5 | 20.0 | 19.5 | 21.0 | 21.0 | 23.5 | 23.0 |
| D2 | 28.5 | 28.5 | 19.5 | 19.0 | 25.0 | 25.0 | 21.0 | 20.5 |
| D3 | 28.5 | 28.5 | 20.5 | 20.0 | 25.0 | 25.0 | 22.5 | 22.0 |
| D4 | 28.5 | 28.5 | 18.5 | 18.0 | 22.0 | 22.0 | 21.0 | 20.5 |
| D5 | 28.5 | 28.5 | 18.5 | 18.0 | 26.0 | 26.0 | 23.0 | 22.5 |
| D6 | 28.5 | 28.5 | 19.0 | 18.5 | 20.5 | 20.5 | 23.0 | 22.5 |
| D7 | 28.5 | 28.5 | 19.5 | 19.0 | 21.5 | 21.5 | 23.0 | 22.5 |
The HPO is now outputting 154.9W and the ISS is back ON. This completes FAMIS 8437.
PSL Power Watchdog Reset (FAMIS 3665)
I reset both PSL power watchdogs at 16:43 UTC (9:43 PDT). This completes FAMIS 3665.
