We found that SUS JM1 had a faulty quadrupus cable, which we replaced it today. Next, I took OLC for both JM1 and JM3 in HAM1 chamber. I applied the offsets, gains and then centered the BOSEMs - and they look good. Next, I will start checking the health of the electronics chain and the suspension itself (i.e. by taking the transfer function measurements).
The offsets and gain for JM1 is recorded in this screenshot - accepted in the SDF (safe).
The offsets and gain for JM3 is recorded in this screenshot - accepted in the SDF (safe).

We started damping both the suspensions - found that the voltmons were not working (Dave found that their gains were set to zero).
With voltmons ON, both the suspensions were damping fine - no overflows on this 28bit DAC.
Adding pictures of JM1 and JM3 I took today.
