  • Patent number: 8120219
    Abstract: The production costs of electrical machines are to be reduced. To this end, it should be possible to use standard transmitters for different axis heights of the electrical machine. The invention therefore provides a transmitter cover for an electrical machine, having a pot-like hood (11) for mounting on the electrical machine and for covering a transmitter, wherein the hood (11) has a central axis. The transmitter cover also has a mounting ring (10) which engages on the hood (11) in an interlocking manner. As a result, the hood (11) is pressed against the electrical machine in the axial direction when the mounting ring (10) is fixed to the electrical machine. This can prevent fastening screws (13) colliding with other fastening screws on the motor, this possibly being the case when only the hood (11) is used to cover the transmitter.

  • Patent number: 8103972
    Abstract: A method and operator control unit is disclosed that uses a screen, softkey buttons and an operating button. If, after a first on-screen display is invoked by briefly pressing a softkey button, the operating button is then pressed while that first on-screen display is displayed on the screen, a user menu is displayed as a second on-screen display on the screen. Then, a softkey button is pressed for a longer length of time while the user menu is displayed, the softkey button pressed in this manner becomes a shortcut on the user menu. The shortcut allows the user to directly invoke said first on-screen display from the user menu. Thus, the operating button provides a user-selected menu of shortcuts that gives the user direct access to predetermined softkey on-screen displays.
