Asked mcc for a quick access to the hall to check on the chamber turbos and GVs.

Found all three turbos ON on min load and the GVs open. The controller for the mdp is really hot. Is it supposed to be like that? It was ON and the pump was at speed.

While writing this entry, I just noticed a Cryo entry that the 2K CB tripped round 6:15 AM. A bit latter I noticed the supply pressure at the ESR dropping and compressor alarms (again). So, it seems that the ESR tripped too?
