PSL Weekly FAMIS Tasks (FAMIS 3675 & 8447)

This morning I performed the weekly PSL FAMIS tasks.

HPO Pump Diode Current Adjust (FAMIS 8447)

With the ISS OFF, I adjusted the HPO pump diode operating currents; this week required a larger increase than usual from all 4 HPO DBs, this is summarized in the below table.  As usual, I attach a screenshot of the PSL Beckhoff main screen for future reference.

  Operating Current (A)
Old New
DB1 51.3 51.6
DB2 53.7 54.0
DB3 53.7 54.0
DB4 53.7 54.0

I did not adjust the operating temperatures of the DBs.  The HPO is now outputting 155.0 W and the ISS is back ON.  This completes FAMIS 8447.

PSL Power Watchdog Reset (FAMIS 3675)

I reset both PSL power watchdogs at 17:55 UTC (9:55 PST).  This completes FAMIS 3675.
