Installed the Variac system for the VEA heaters at both end stations.  Had quite the temperature excursion (69degF) due to the feed back to the controller not being properly setup For some reason in this state the Variacs go to full on.  We corrected this and the system is now functioning.  We still have problems at EX.  Half of the heater elements are bad so we are only running on a single stage at most.  I have Y end set to 7mAmps and X to 8mAmps.  Will probably turn Y down as the temperature settles to require less cooling for control.   At some point we will convert over to the heater being in the control loop but that will wait.
