keyword=target reboot
at 11h03 PM, for some unknown reason the target controls rebooted, and came back ~ 1min later.
Everything seems to come to normal, except for 2 things which are still in 'high' (yellow level) :
- temperature in D2 loop
- pressure in H2 loop
The strange thing is that the "threshold values" used to caracterise these yellow levels are not accurate : the temperature of D2 loop is close to 22 K, but the "yellow level" is at 21 K -which correspond to the H2 loop- . For the H2 pressure, the presure is around 26.7psi, and the yellow level at 26psi. I don't know what these values should be, but the pression for D2 loop is around 25psi...
After investigation, I have found that the threshold values are not accurate for both loops (i.e. we have values corresponding to H2 for D2 loop, or vice versa, or nothing at all ; I mean negative LOW and LOLO and very high values for HIGH and HIHI).
