PSL Weekly FAMIS Tasks (FAMIS 3670 & 8442)
This morning I completed the weekly PSL FAMIS tasks.
HPO Pump Diode Current Adjust (FAMIS 8442)
With the ISS OFF, all operating currents of the HPO pump diode boxes were increased by 0.1 A; 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 | 50.4 | 50.5 |
| DB2 | 52.9 | 53.0 |
| DB3 | 52.9 | 53.0 |
| DB4 | 52.9 | 53.0 |
The operating temperatures of the diode boxes were not adjusted. With the ISS back ON, the HPO is outputting 153.7 W. This completes FAMIS 8442.
PSL Power Watchdog Reset (FAMIS 3670)
I reset both PSL power watchdogs at 16:19 UTC (9:19 PDT). This completes FAMIS 3670.
