We disconnected the magnet leads at 1L21, 1L22,1L23,
1L24 and 1L25 girders.

I was giving permission by Radcon to enter 1L23, 1L24 and
1L25

Tape the leads together, roll up the cables and tied them up
to the cable tray. We place a Magnet Verified De-Energized
label on the girders.

After running the harp through, we noticed the peaks don't look as they should.
Just out of curiosity, we ran IHAM803 -- peaks look great there. Why isn't 905 working?
Is it an amplifier issue?

Also, I just wanted to note that the component list does not include IHAM905 -- so I selected 803.

Tightened leads to MBHK101H/V and MHBM502H/V. 101H/V were loose by touch. Took over a turn n a half to tighten the leads at the magnet. Half turns on a 1 or 2 leads on 502H/V at the magnet. Spares are in the control room if needed.

From Leo:
The existing vacuum controls for zone 1L05 are on the 4-Zone crate in NL03. We are taking the 1L05 vacuum controls away from the NL03 crate and moving them to a new C-100 style stand alone crate. This means we have to make the old crate "forget" it ever had control of 1L05. These old 4-zone crates all have hand wired back planes that were never intended to be modified. We are essentially performing "brain surgery" on the crate.

Inspected the magnet this morning. Tightened the leads to the vertical and horizontal magnet. Maybe a half turn on one or two connections at the magnet. Spares are needed if the card needs to be replaced.

There were some manual steps necessary to restore FSD functionality. After the quarter has reached GDR gradient, the clear faults button on the cavity exop page must be pushed to clear the ramp fault, then the Master Reset. This will clear the interlocks chassis FSD fault. The node ITMaster FSD node was masked to circumvent this problem earlier. After following the sequence, the node was unmasked and the GDR trip to SEL FSD became functional. I will look to see how to make this process simpler for operations.
