PSL Weekly FAMIS Tasks (FAMIS 3659 & 8431)
This morning I performed the weekly PSL FAMIS tasks.
HPO Pump Diode Current Adjust (FAMIS 8431)
I adjusted the HPO pump diode currents, changes summarized in the table below. All adjustments were done with the ISS OFF. I have attached a screenshot of the PSL Beckhoff main screen for future reference.
| HPO Diode Currents (A) | ||
| Old | New | |
| DB1 | 48.9 | 49.0 |
| DB2 | 51.8 | 52.0 |
| DB3 | 51.8 | 52.0 |
| DB4 | 51.8 | 52.0 |
I then tweaked the DB operating temperatures. The only change was to DB1, all diodes changed from 29.0 °C to 28.5 °C; no changes were made to the operating temps of DBs 2, 3, or 4. The HPO is now outputting 154.9 W and the ISS has been turned back ON. This completes FAMIS 8431.
PSL Power Watchdog Reset (FAMIS 3659)
I reset both PSL power watchdogs at 16:26 UTC (9:26 PDT). This completes FAMIS 3659.
