[dsg-hallb_rich] RICH hardware interlock

[Tyler Lemon]

Hi Valery,

I’m away from home now but I’ve been able to look at some of the RICH S1 things remotely.

I can see that the two air flows, air pressure, and Nitrogen flow for RICH S1 are not updating.

But, I can also see that the temperatures and humidities are updating for RICH S1. And I can see that there is air pressure and air flow from the buffer tank for S4.

With this, I think there has been an issue with part of the S1 chassis (specifically the expansion cRIO) that is causing the issue.

In reality, there is still probably airflow to S1, we just can’t monitor it currently.

Im not able to come in right now. If the problem persists, I can come in later tonight or tomorrow.

-Tyler

Hello guys,
Can anybody help us with the hardware RICH interlock.
The reading of Air Flow and Air pressure for RICH in sector 1 show zero values.
Thank you,
Valery
