Daily Shutdown

These procedures are used for shutting down MagAO-X at the end of a work period.

Rules to follow:

  • do not power off a DM unless it has been released

  • do not power off a temperature-controlled camera unless its temp is 20C or higher

  • do not power off instcool!

  • steps can be done in parrallel, so start warming up cameras, go on, then come back

Warning

You must be monitoring the relative humidity for dmtweeter and dmncpc any time their power is on.

Warning

instCool must be on while the computers are powered.

Lunch Break

If you are just taking a break and plan to come back to keep working, you only need to shut off dmtweeter and dmncpc:

  • open the loop if closed (holoop for tweeter, loloop for ncpc)

  • press “loop zero”

  • zero flat

  • zero all ch

  • release

  • power off dmtweeter and dmncpc

Minimal shutdown

This procedure can be used if you expect to startup in a few hours. The main goal here is to shutoff “the expensive stuff”.

  • For each of camsci1, camsci2, camwfs, camvisx, but not camflowfs and camllowfs.

    • close the shutter

    • warm up to 20C (use cameraGUI, change setpoint)

    • wait for it to finish

    • power off

  • dmtweeter and dmncpc

    • open the loop if closed (holoop for tweeter, loloop for ncpc)

    • press “loop zero”

    • zero flat

    • zero all ch

    • release

    • power off

  • dmwoofer

    • turn off woofer offloading if on

    • zero woofer offloading

    • zero flat

    • zero all ch

    • release

    • power off

  • ttmmod

    • if modulating, first press set in Pupil Alignment GUI

    • press rest

    • power off

  • ttmpupil

    • press rest in Pupil Alignment GUI

    • power off

  • ttmperi

    • press rest in Pupil Alignment GUI

    • power off

  • Others

    • power off camtip and camacq (they are just heaters)

    • power off source

    • power off tableair

  • Remaining devices such as focus stages and filter wheels can be left on, which will make alignment easier next time.

Standard Daily Shutdown

If MagAO-X will be unused for a longer period of time (overnight or a weekend), we typically shut down everything but computers, networking and cooling.

  • Follow the steps in Minimal shutdown above.

  • Everything on the user tab of pwrGUI should be off. Items can be shutdown in any order. Occassional errors in the logs during shutdown may occur.

  • Everything on the ninja tab of pwrGUI should be on (with the possible exception of camflowfs and camllowfs)

Warning

Do not power off instCool.
