[Ian, Koji] - Activity on 25th (Fri)
We continued working on the ETMY electronics replacement.
- The units were fixed on the rack along with the rack plan.
- Unnecessary Eurocard modules were removed from the crate.
- Unnecessary IDC cables and the sat amp were removed from the wiring chain. The side cross-connects became obsolete and they also were removed.
- A 18V DC power strip was attached to one of the side DIN rails.
Warning:
- Right now the ETMY suspension is free and not damped. We are relying on the EQ stops.
Next things to do:
- Layout the coil driving cables from the vacuum feedthru to the sat amp (2x D2100675-01 30ft ) [40m wiki]
- Layout DB cables between the units
- Layout the DC power cables from the power strip to the units
- Reassign ADC/DAC channels in the iscey model.
- Recover the optic damping
- Measure the change of the PD gains and the actuator gains. |
