Another note: Don't trust the PSL shutter and the switch on the MEDM screens! Always use a manual block in addition!!! We discovered upon closeup that hitting the "Closed" button, while it reads back as if the shutter is closed (with the red box around the buttons), does not in fact close the shutter. The shutter is still wide open. This must be fixed.
Has anyone tried pushing the "reset" button on the Uniblitz driver?
