Nutstinee, Stefan, Matt, Sheila, (Hugh, Dave, Jim, others on the phone)
We have basically recovered from this morning's outage about an hour ago. There were a few things worth noting in additin to what people wrote earlier:
-
I don't think that the analog camera switching is working, the images are displayed fine but we can't change which camera is on which monitor.
-
Nutsinee with instructions from Hugh tried to bring the corner HEPI pump station back but it tripped several times. Hugh explained that this was probably because the fluid level in the reservoir was a little low for some reason, so Nutsinee and I losened the collet on top of the resevoir and lowered the sensor about a half a centimeter further into the resevoir. After this the servo came on fine.

We called Jim W because the BRSs were off causing the seismic configuration manager to get stuck; it has been a windy afternoon and the optics were moving more than usual. Jim pointed us to the good instructions in T1600103, (including a pointer to this in the power outage recovery document would be helpful). This worked fine for Y, but we were stumped by not knowing the password for X. Matt and Stefan were able to reset it by driving to the end station.

Before the BRSs were back on, we tried to reduce the motion of the optics by choosing useism from SEI_CONFIG. This caused all the corner station ST1_CONF guardians to go into error. To get out of this situation we requested down and reloaded. This cleared the errors, but apparently down is not conected to the rest of the graph. At the end of this somehow the corner station blends ended up half switched between 90mHz and 250 mHz (90mHz blend names outlined in blue for some DOFs, but staying blue and not changing.) After calling Jim again I set the blends to 250, checked that all corner station sensor correction was off, and then manually took the guardian to the state BLEND_Quite_250_SC_None. I set each of these guardians to manual, and turned on sensor correction by changing to BLEND_Quite_250_SC_Windy.

The highlight of the day was the new relay reset for in vacuum high voltages.
