Attached are an Excel file (inside of a .zip), a plot for all the data, and a picture showing where the temperature sensors are located on the coil.
Some comments:
* The samples are taken every 100 ms
* All the temperature sensors were actually sampled 19 ms later than the other signals, but I've put them all into the same 100ms time bin.
* Both the LCW Return Pressure and MPS Current are on the same secondary axis in the plot, all the other ones use the same primary axis
* Around sample # 10k is when the supply flow started to be reduced
* Around sample # 12k is when the supply flow at the wall was completely closed, however there was still around 0.3 gpm of bleed through
* Mike Beck said this was expected
* Around sample # 24k is when the supply flow at the manifold was closed
* Around sample # 33k the supply flow at the manifold was opened
* There were some additional valve adjustments to the wall supply around sample # 34k
* Around sample #40k is when the ramp to zero on the supply was started
* Max temp was ~64 C on Temp 2
I suspect some of the channels would be more useful plotted individually or zoomed into particular time frames. Let me know if there's anything in particular you'd like to see.
