We have reason to believe that CP3 is fixed and the ice blockage is gone. However, there was an auto overfill today at 11 am which may be skewing the reading, so we will let things settle overnight. Reservoir level reading is 100% on Beckhoff (software limit) and 120% on Magnehelic. Today we found the sensing line valves open to transducer, along with the valve that isolates them from each other, so we have been flowing much of the GN2 straight out the exhaust. Kyle checked these valves last night and thought the isolation valve was closed, but turns out it was just sticky and actually open.
We connected GN2 to CP4 sensing line, and will leave it connected for days vs. hours this time (readout on MEDM falsely shows 100% full). The flow is essentially zero right now, but set to 2 LPM in case it does open up. Isolation valve between two sensing lines is closed.
We are leaving CP3 LLCV in manual mode tonight.
