  3. Double click on VEDCSHV_UI_FSM
  4. The following window appears:
    VEDCSHV_UI_FSM.PNG
  5. expand VELOA/C_DCS
  6. right click on VELOA/C_DCS_TB
  7. take control by cliking the padlock
  8. click on the Interlock circles (repeat the next 9 steps for all the three circles)
  9. you will be prompted with the question "Do you want to change the ELMB state?", answer YES (preoperational)
    ELMB_Preoperational.PNG
  10. You will get the Status_and_Event_reg window.
  11. click on Check status (in commands frame), you will see all channels are masked (the mask box is ticked)
  12. click on reset board, and then load mask configuration (both buttons are in the Commands frame)
  13. check status again and you should see that the 4 interlocks fired.
  14. click on the Send button in the Control Register Reset frame
  15. To make sure that everything is ok (ie that the interlocks have gone) check status again
  16. Close the panel
  17. Switch on the Board again (click in the state of the corresponsing board and select "Switch_ON", in the VELOA/C_DCS_TB panel). The state becomes ready and the status of the ELMB becomes OPERATIONAL.

Trouble shooting

  • Hardware interlock signals coming from the temperature boards, Vacuum (forced until further notice, 28/05/2008), Cooling and BCM system (forced until further notice, 01/08/08) and to the LV and HV (taken out until further notice, 01/08/2008) systems, are treated into the interlock unit. See picture below:
    Interlockbox.jpg
    • This unit is located in D3E05 slot 6.
    • The input signal Leds (not the spare channels) on the from panel can have 3 states:
      • green - OK
      • orange - signal forced
      • no green nor orange LED on - interlock signal fired.
    • The output signal leds (not the spare channels) can be green (ok) or off (interlock fired)
  • Hardware interlocks between the PLCs (cooling-vacuum, vacuum-motion) are treated directly. An interlock status panel can be seen on the corresponding PLC.
  • The vacuum PLC receives status information from the LHC vacuum
  • The motion system is interlocked to the LHCb beam dump signal
