keyword=Loop 1 fan reset to 34 Hz/14%, cooling down now
Loop 1 fan frequency went to 0 (set point 10%, or 24 Hz), caused high power heater went high, and loop temperature/pressure went up.
I turned down high power heater. Was able to set fan to 14% (34Hz).
Since temperature was at 26K and pressure at 32 psi, I opened J-T a few % to cool it down. It is still in the process cooling: it is 25K/26 psi now. High power heater back to PID mode.
