Hi Valery,


Something weird happened to your message and the mailing list didn't let it go through.


This is just to forward it to everyone else.


Best regard.

Hi Tyler,
We got RICH alarm today around 15:00. It is B_DET_RICH_INTLK_AIRPR1.
If you take a look to the attached plots you will see that AIRPR1 dropped from 100 (in Dec 2018) to ~30 (Apr 2019).
The alarm limit is set to the value of 25 for a moment.
The AIRFLOW1 and AIRFLOW2 are almost constant.
Could you please take a look to this problem?
Thanks,
Valery
