Re: Problem stsetch2 SNF 2011-05-20 18:38:05: STS2 Backing pump Shut Down

The problem was caused by a short of a 24Vdc line at the sense switch on the by-pass vacuum valve for the chamber. He system still needs to be checked out and all the heaters need to be turneed and brought up to steady state temperature. I expect the system to be back up by late afternoon. Jim
