Wed CP1 Fill, manually cancelled when TCs did not trip

Wed Feb 21 08:04:22 2024 ALERT: Fill done (errors) in 4min 19sec

Before the fill I noted the TCs were very high, +35C. I raised the trip temp to -60C, but as it happened it turned out not to be high enough and TC min was -56C. With the discharge line pressure up at 0.7 and the TCs flatlined, I manually canceled the fill.

Gerardo thinks there is ice build up, the dewar was filled yesterday and I noticed vapor at the discharge.
