I added a check for the JAC shutter to the 'LOCKING' state to its guardian. This was because it was closed when the guardian was trying to lock JAC this morning and it took us a while to figure out.

We haven't had a chance to check this today due to efforts to lock DRMI but I will check it on Monday.

Its on lines 207-209 of the script.

 if ezca['SYS-MOTION_C_SHUTTER_M_STATE'] != 0:#added to notify if shutter closed. J Wright 2026-03-13.
            notify('Shutter closed. Check shutter trigger values.')
            self.timer['waiting'] = 5

Thanks to Tony for helping me debug gedit.
