Raith Status until receipt of EDA 3 control unit for testing this issue.
Friday February 11, 2011:
Testing the system today the data collected indicates that the piezo post controlling the leveling of the Laser Interferometer Stage are in fact not moving as requested by the Height Control Module SW; although the display icons of the piezo post show they moved....
Users are suggested to operate the system with centered piezos which I have recently calibrated accurately until the replacement control unit arrives.  It was ordered Friday for expediated shipping through Raith USA.
