Follow-up Re: Hall A ozone detectors?

Log Number: 4050326Logbook(s): Body: 

The downstream monitor signal is output through a raspberry pi module and the signal is much more stable than the signal from the sensor at the entrance.

I've reached out to Ellen Becker who will try to switch the entrance sensor to raspberry pi to improve signal stability before the hall is locked today.

While the signal is noisy when no ozone is present, applying ozone to the sensor stabilizes the signal and the EPICS display matches the local units display at the sensor.

If Ellen is able to switch the signal, we will see a major improvement.

COMMENT ON Investigate MZA8S03 Magnet Overtemp

Log Number: 4050324Logbook(s): Body: 

Plan for MZAAT03 follows a similar line of solution pursued Friday for MZA8S03.

1.reverse flush(Beck+support fromDC Power for LOTO and anything else)
2. check temperature switches and replace if needed(Beck+support as needed)
3. check rtd's downstairs to see why they are not resetting(Broeker+Kissinger)
4.check klixon wiring to make sure they are ok (Broeker+Kissinger)
5. If M.Beck does not find a problem with the magnet, a citro-clean flush will have to take place with support from N.Wilson and installation group.

Total time estimate 2 hours for troubleshoot and reverse flush.
