Found that the DRMI was misaligned this afternoon. Trends show that the HAM5 optics moved and started shaking a little around 8 AM.
I'm able to get the ISI into damped mode, but it trips its vertical actuators if I try to transition into any of the 3 isolation modes via its guardian screens.
Similar situation for HAM5-HEPI. It also trips its vertical actuators (but for this one, the 'plot ACT Trip' button fails to produce a plot; it has some NDS or channel name problems in the script).
We are trying to track down what optics have moved, but this is hampered somewhat by the lack of a SUS DRIFT screen here at LHO.
Having this running would make it easier to find what optic has moved when we have these mysterious misalignments.
same situation on HAM4; HEPI disabled and ISI vertical actuators trip while ramping up any isolation mode. Leaving it in damping only.
To get the interferometer back, we've torqued the SR3 back to its optical lever values from last night. That seems to be the main culprit, so this is probably due to the HAM5 SEI problems. Until the HAM4/5 can be brought back into some Isolated mode we are not able to get the DRMI to lock.
Computer problem--there is no signal passing through the IP to actually get to the platforms. McCarthy and I will trouble shoot shortly.
