Operating the VELO Motion System while being under vacuum

Make sure the PVSS-project "VEDCS_VacMot" is running under "velo_user" on "vedcs02w". If not, start it and also start via "Vision" the panel G:\velo\pvss\VELO_VacuumMotion\panels\VeloMotion_UI_Main.pnl

A number of conditions has to be satisfied in order to be able to move the VELO-detectors.

  • the 2 red emergency mushroom buttons of the stepping motors in rack C3B03 on platform C3 have to be pulled to the out-position,
  • all 3 coordinates of the system have to be in "referenced"-mode, as specified in the panel,
  • the motion-PLC has NOT to be in "local" but in "physics" mode,
The actual readings and a lot more can be seen at the Motion pages on the PLC-screen in rack C3B05 on platform C3. However, access to these pages is password protected.
