  • Preparative monitoring apparatus for operation of a press
    Patent number: 4446787
    Abstract: A preparative monitoring apparatus for operations of a press displays interlock conditions relating to an operation currently in operation whose establishment is indespensable for the operation to be performed as well as the title of this operation. These interlock conditions are displayed by means of light emitting elements and the title is displayed by a display device provided on a panel. When either one of these interlock conditions is unestablished, the light emitting element corresponding to the unestablished condition and the display of the title are caused to flicker, thereby indicating occurrence of abnormality in the press.
