PTW-12240 covers 3" knockouts in racks SL03B11, SL13B09.

There is a linked PTW to this ATLis, 12242 that covers CPS breaker handle replacement, although which exact zones is not specified. PTW also calls out PSS performing ZVV, which doesn't seem right.

Once exact PTW to be used is confirmed, and once planning is approved for it, please submit this ATLis with an estimated date for execution.

Thanks.

Tuesday:
Moved mirror puck to SM 1, puck 34 to SM 1 before removing magnets from manipulators
Verified heater working: 5A -> 1 V, 6A for 15-20 min got above 50C.
Checked RGA trace with heater on - no significant change, slight increase in pressures

Moved turbo cart from beam left at 1I01 to beam right with pinch off valve to clear space for laser box work

Closed valve between overboard IP and turbo cart - no significant change in RGA trace. Final bagged leak check of system before starting bake setup - found small leak in gauge on pump cart, this should not affect the bakeout.
