Power Cycling the camera

Symptom

  • A Crate Reset didn't solved a FTU or FAD problem

Solution

  • stop all scripts: dimctrl --stop from a bash
  • set bias to 0: - BIAS_CONTROL/SET_ZERO_VOLTAGE
  • Stop Trigger:
    • FTM_CONTROL/STOP_TRIGGER
    • or Stop Trigger in the left part of the GUI
  • FTM_CONTROL/DISCONNECT
  • FEEDBACK/STOP
  • if fadctrl is in state WritingData?
    • FAD_CONTROL/CLOSE_OPEN_FILES
    • fadctrl now should be in state connected
  • FAD_CONTROL/STOP

Now power cycle the camera

  1. Switch off the agilent camera in the FACT Container
    • open the page 10.0.100.100 from a computer in the internal network of La Palma (can be your computer if you use vpn)
    • push 'Camera Off' to stop the camera (now only 'Bias Power' and '24VDC Interlock Power' should be 'yes')
  2. wait for about 15 min
  3. switch the agilent on
    • open the page 10.0.100.100 from a computer in the internal network of La Palma
    • push 'Camera On' to start the camera (now all 5 points should be 'yes')
  4. make sure that clock-conditioner is locked
  5. follow the preparation#startup Start-Up procedure? to get the system running again

To check if the clock-conditioner is locked, you may check in the gui in the tab

  • 'Trigger' the led next to the pulldown 'DRS sampling frequency'
  • 'FAD' with mouse over on the LED next to 'Reference Clock' whether all 40 values are roughly 1/1024
