PSL Weekly FAMIS Tasks (FAMIS 3662 & 8434)

This morning I completed the weekly PSL FAMIS tasks.

HPO Pump Diode Current Adjustment (FAMIS 8434)

With the ISS OFF, I adjusted the HPO pumpd diode operating currents.  All currents were increase by 0.1 A; I have attached a screenshot of the PSL Beckhoff main screen for future reference.  The changes are summarized in the below table:

  Operating Current (A)
Old New
DB1 49.3 49.4
DB2 52.3 52.4
DB3 52.3 52.4
DB4 52.3 52.4

I did not adjust the operating temperatures of the diode boxes.  The HPO is now outputting ~154.9 W; the ISS is now turned ON.  This completes FAMIS 8434.

PSL Power Watchdog Reset (FAMIS 3662)

I reset both PSL power watchdogs at 15:52 UTC (8:52 PDT).  This completes FAMIS 3662.
