the 70 s could be due to transit time/ trip initiation latency (solenoid takes more time to ack. flipped bit)... etc.
i guess relief valve installation is in the event horizon upcoming down time.

Regarding the ramp today: https://logbooks.jlab.org/entry/3657129

Any ideas on why the Torus went at 14:48:24 vs the Solenoid at 14:49:34 since they should be using the same tags/values?

Also, if the flow was actually bad (according to the MPS) shouldn't we have seen the flow bit on the MPS trip?
