The operating mode selection and access permission system PITmode combines safety and security functions in one system. The devices enable functionally safe operating mode selection and the control of access permissions on plant and machinery.
PITmode devices can be used on plant and machinery in which you must switch between a range of control sequences and operating modes. Each employee can be issued machine enables and permissions that correspond to his or her skills using coded transponder keys with RFID technology. The safe evaluation unit detects the specified operating mode such as automatic, manual access under restricted conditions or service mode, evaluates it and provides functionally safe switching. This prevents misuse and manipulation, while protecting human and machine.
