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

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

Minimal shutdown

This procedure can be used if you expect to startup in a few hours, right away the next day, etc.

The main goal here is to shutoff “the expensive stuff”. Namely:

  • dmtweeter

  • dmwoofer

  • dmncpc

  • camwfs

  • camsci1

  • camsci2

  • camlowfs

  • ttmmod

  • ttmpupil

  • ttmperi

Cameras (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

  • note: for camlowfs, power off under both pdu1 and usbdu0.

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

  • zero flat

  • zero all ch

  • release

  • power off

ttmmod:

  • if modulating, first press set in Pupil Alignment GUI

  • press rest

  • power off in Power GUI

ttmpupil

  • press rest in Pupil Alignment GUI

  • power off

ttmperi

  • press rest in Pupil Alignment GUI

  • power off

Additionally:

  • power off camtip (its just a heater)

  • 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 (say a weekend), we typically shut down everything but computers, networking and cooling.

At the end of this, the following things will still be on:

  • pdu0.compicc

  • pdu0.comprtc

  • pdu0.dcpwr

  • pdu0.swinst

  • pdu2.camflowfs

  • pdu2.camllowfs

  • pdu3.blower

  • pdu3.fanaux

  • pdu3.fanmain

  • pdu3.instcool

Note: it is critical that you not shutdown instcool while compicc and/or comprtc are on!

Follow the steps in “Minimal Shutdown” above.

Everything else (except the items listed above) can be shutdown in any order. Occassional errors in the logs during shutdown may occur.
