Shutdown karlsuss:

[zhang at snf.stanford.edu]

After I enabled Karlsuss, screen says Ready for Start 
Press "LOAD" button. But after I pressed "LOAD", 
screen says OVERCURRENT cannot continue. 
Bob Wheeler suggested that I try rebooting it, and if still 
not working, write as a shutdown. So I tried turning 
power switch off and on twice but it gave me the same 
error mmessage.
Previous user reported that Coral system went down for 
a while just when he was done with using Karlsuss, So it 
got automatically disabled itself.
