PSL Weekly FAMIS Tasks (FAMIS 3666 & 8438)
Today I completed the weekly PSL FAMIS tasks.
HPO Pump Diode Current Adjust (FAMIS 8438)
With the ISS turned OFF, I adjusted the operating current of the HPO pump DBs, changes are summarized in the table below. I also attached a screenshot of the PSL Beckhoff main screen for future reference.
| Operating Current (A) | ||
| Old | New | |
| DB1 | 50.0 | 50.2 |
| DB2 | 52.7 | 52.8 |
| DB3 | 52.7 | 52.8 |
| DB4 | 52.7 | 52.8 |
I also adjusted the operating temperature of DB1: all diodes were running at 28.5 °C, they are now operating at 28.0 °C. This ISS is now back ON and the HPO is outputting 154.9 W. This completes FAMIS 8438.
PSL Power Watchdog Reset (FAMIS 3666)
I reset both PSL power watchdogs at 16:42 UTC (9:42 PDT). This completes FAMIS 3666.
