Requesting LERF Lab Room #3A Safety System cabinets for 'ODH head bypass Instructions' step #5 be changed to ask for channel number instead of module number...

Upon bypassing an ODH head in the LERF we noticed a misprint in the instructions. Step #5 in the Instructions (FIG.1) say to "Select the module using the 'up' or 'down' keys"

following the instructions while using the reference chart would lead you to selecting the ODH head's module # instead of the ODH head's channel #.

Entering the module number at instruction step #5 leads to bypassing incorrect ODH heads.

Actually, it retook setpoint on its own. Still affected positions in Hall B. DC Power does plan on swapping the trim card during the maintenance period later today on 5/13.

As aforementioned, the 1L12 MO temp does recover after a couple hours every time but does drag the NL gangphase with it. Other than that, it seems there are no ill effects. The OPS-PR for this is linked.

I foresee the next occurance happening on June 27th at around 18:30. See you there!

corrections to linked (via FIG.1 clickable "ODH-LERF" EDM screen) online photos should be made for ODH heads 214 & 213. The Lab Room #3A in the photo should be changed to Lab Room #3 (or vise versa)

Also, "ODH-LERF" EDM screen labels Lab Room 3A where physical lables on the door say Lab Room 3. The same change request apply here as well

Additional correction should be made for ODH head 222 & 221 linked online photos. Where photos say Lab 3B and physical labels on door say Lab 3A.

The corrections are to match the physical labels on the doors.

After ODH alarmed via MCC PSS console, Ops 2-person team went to investigate. No hazardous levels were identified. Adjacent head OM221 had already been bypassed, so Lab Room #3A (labeled incorrectly as 3B in referenced photo FIG.2,3) has been roped off and declared as an ODH2 area. SSG has been informed and Lab Room #3A (labeled incorrectly as 3B in referenced photo FIG.2,3) will need further investigation before de-posting it

FIG.4
Additional corrections to linked (via FIG.1 clickable "ODH-LERF" EDM screen) online photos should be made for ODH heads 214 & 213.

Adjacent head in Lab 3A is already bypassed. If no ODH condition is discovered, investigation team will bypass the alarming sensor and post Lab 3A as an ODH 2 area, per SSG on-call instruction.

Sending Ops responders to investigate and contacting SSG. Looks like a sensor problem.

The 2C00 IDX was rising, so I attempted to improve it with gangphase adjustments and also by steering at 2T09V. This coincided with a mild improvement at 2C00 that felt more like the machine drifting than anything I was correcting. My messing about, perhaps in conjunction with said drift, definitely improved the midstream halo rates.
