- meclas.TTL_shutter_Status() tells you which TTL shutters are currently opened vs closed
- meclas.TTL_shutter.Toggle('openall') opens all TTL shutters
- meclas.TTL_shutter.Toggle('closeABEF') closes AB and EF TTL shutters
- meclas.TTL_shutter.Toggle('openWW') opens WEST TTL shutter
- meclas.TTL_shutter.Toggle('closeXX') closes EAST TTL shutter
- meclas.TTL_shutter_refresh.Refresh() see text below
- If you toggle the shutters using the button or the EPICS screen instead of Python, nothing is keeping track of the shutter state, so you will confuse the laser -- it will think it has one state when really it has another! As such, never touch the button or the GUI unless absolutely necessary!
- If things get out of whack, you can always come to the hutch, visually verify that ALL SHUTTER ARE OPEN, and then type in the command: TTL_shutter_refresh() This will reset the counter/reference back to being all open.
