Abstract
A method is proposed for operating a vacuum handling device controlled by a programmable controller () which can be connected to a machine controller (), with at least one vacuum generator () and with a number of gripper modules (), which are connected to the vacuum generator and are each equipped with a first pressure sensor () and with a control valve () for the vacuum in the gripper module, and which are connected to the programmable controller. The control valve in the gripper module is closed in a first switching state (vacuum on) of the programmable controller and is detected up to the control valve () by means of a second pressure sensor () in the vacuum generator.
