Starting a compression

All of this is done in the Voggenreiter controller

  • go into Profile and set a ramp, for instance
    • 10 mn to reach 10 bars,
    • 60 mn for 30 bars,
    • and finally 2000 mn at 30 bars as final step
  • go into Settings
    • check Data storage and that you have a .dat log file
    • make sure that the ckeckbutton save is selected
  • go into Controls,
    • Active distance control should be On,
    • Hold follow should be Hold position,
    • Hold position ramp time should be in agreement with compression times you chose in pofile, 4200 sec for 70 mn, for instance,
    • End value is the position that differentials rams should go to, to be determined with Jeremy.
  • Go into Profile
    • Menu PLC controller
    • Download profile to controller
    • Menu PLC controller
    • Run continue profile
  • Go into Controls, activate Ramp On/Off

The press should be going up in pressure...

Start a deformation

If you are at pressure and want to start a deformation....

  • Open the application: press monitor
  • Open the Controls tab
    • Look at differential rams in Control tab
    • choose end value and time
    • example: remove 0.350 mm in 2h for 1 to 3.10-5 s-1
  • Open the Profile tab
    • Suspend profile in PLC Controller menu
    • remove about 2% of pressure on main ram over 2 hours, plus a long plateau afterward
    • Download profile in PLC Controller menu
    • Run profile in PLC Controller menu
  • Back to differential rams in Control tab
    • Active distance control should be On,
    • Hold follow should be Hold position,
    • Select Ramp to start deformation

You are good to go.
