HAM6 LVEA floor accelerometer seems not working
Since May 11, 2023 22:18 the spectrum of H1:PEM-CS_ACC_LVEAFLOOR_HAM6_Z_DQ seems low. I don't quite see anything in the alog about this. Is this the expected behaviour of this channel?

Yes, that channel is not working. It was unplugged during the run-up to O4 and I wasn't able to find where it was disconnected at - the accelerometer cable disappears into some cable trays that run the length of the output arm. We have some sensor coverage in the area from three accelerometers mounted on the HAM 6 chamber walls.
