restarted all models at EY and on h1sush2b

An earlier glitch required a restart of all models at EY (h1susey, h1seiey, h1iscey and h1susauxey). The order was to stop all models on the Dolphin'ed machines, then start all the models in the order h1iscey, h1seiey and h1susey. Then the sus aux was stop-started. Finally all IPC errors and CRCs were cleared.

Later an unknown glitch caused the models on h1sush2b (sus-im system) to stop. The dmesg is just showing Dolphin-like errors. I stopped and restarted the two models on this system.

H1 SUS ETMY UIM/L1 Coil Driver Monitor

WP 7064
FRS 8013
alog 35974
alog 37169

Continued looking at the ~4300 ct offset on some of the monitor channels for ETMY L1 (UIM). SCSI cable was disconnected from both the AA and IO chassis. Visual inspection showed no bending of pins on either the cable or connectors. Cable was reconnected and all monitor signals showed reasonable values, no offset. Missing mounting hardware was placed on the ADC interface cards on the IO chassis. During this work, the front end computers at EY glitched and had to be restarted.

PSL Weekly FAMIS Tasks (FAMIS 3657 & 8429)

I performed the weekly PSL FAMIS tasks during today's maintenance window.

HPO Pump Diode Operating Current Adjustment (FAMIS 8429)

All HPO pump diode operating currents were increased by 0.2 A (this was done with the ISS OFF).  The first attachment shows the diode box decay over the last 7 days, and the second shows the PSL Beckhoff main screen after the operating current adjustment was complete (included for future reference).  The below table summarizes the operating current change:

  Operating Current (A)
Old New
DB1 48.7 48.9
DB2 51.6 51.8
DB3 51.6 51.8
DB4 51.6 51.8

I did not adjust the operating temperatures of the diode boxes.  The ISS has been turned back ON and the PSL is now outputting 157.5 W.  This completes FAMIS 8429.

Power Watchdog Reset

I reset both PSL power watchdogs at 16:22 UTC (9:22 PDT).  This completes FAMIS 3657.

SHIFT SUMMARY:

Decent shift with only a few glitches.  Lock approaching 35hrs at a steady 65Mpc.  Most of the shift the PCal y DIAG_MAIN alert was not around, but it appeared at the end of the shift.

Today would normally be a Maintenance Tuesday, but this week we are making it a Maintenance Wednesday due to today's holiday.

This Will Be A NON-Maintenance Tuesday, But....

Since they will only be driving down the arms & staying outside, will keep H1 in OBSERVING.

Mid Shift Status

Approaching 31hrs of lock.  H1 running at steady 65Mpc.

Took a peak toward the fire area and might have saw a faint glow on the other side of the Umtanum Ridge---nothing to worry about.

edit:  ~4:10 amPDT Saw a vehicle lingering around the LHO entrance, then the sign and then parking a while from the sign for ~15min.
