Abstract

A control device for controlling operating parameters and control functions for the operation of a laboratory centrifuge. The control device has a panel for displaying a visual representation of at least a part of the operating parameters and control functions such as speed of rotation, acceleration temperature, etc. A control switch sets the operating parameters and control functions, this switch being capable of at least two independent movements—a first movement including a rotation about an axis, the second one a displacement along the axis. One of these switch movement, e.g., rotation, provides for the selection and change in setting of one of the operating parameters and control functions, and another of the switch movement, e.g., displacement, provides for acceptance of the selection and acceptance of the setting.

Claims

1. A control device for controlling operating parameters and control functions for the operation of a laboratory centrifuge, said control device comprising:

a display panel for displaying a visual representation of at least a part of the operating parameters and control functions;

a control switch for setting the operating parameters and control functions, said control switch being capable of at least two independent movements, a first of said movements comprising a rotation about an axis and a second of said movements comprising a displacement along said axis;

wherein said display panel is configured to display said visually represented operating parameters and control functions in response to movement of said control switch; and

wherein one of said movements provides for selection and change in setting of one of the operating parameters and control functions and another of said movements provides for acceptance of said selection and acceptance of said setting.

2. The control device of claim 1, further comprising:

a control panel comprising said display panel and said control switch; and

a plurality of separate switches arranged on said control panel for powering the laboratory centrifuge and for locking a cover of the laboratory centrifuge.

3. The control device of claim 2, wherein said operating parameters and control functions comprise speed of rotation, centrifugal acceleration, rotor acceleration, rotor braking, treatment time, treatment programs, signaling of operating errors, and signaling of imbalances and for selecting rotor type, receptacle type and radial values of a rotor.

4. The control device of claim 3, further comprising an acoustic signal associated with each said change of setting.

5. The control device of claim 4, wherein said control switch is positioned substantially centrally below said display panel.

6. The control device of claim 2, further comprising an acoustic signal associated with each said change of setting.

7. The control device of claim 3, wherein said control switch is positioned substantially centrally below said display panel.

8. The control device of claim 6, wherein said control switch is positioned substantially centrally below said display panel.

9. The control device of claim 2, wherein said control switch is positioned substantially centrally below said display panel.

10. The control device of claim 1, wherein said operating parameters and control functions comprise speed of rotation, centrifugal acceleration, rotor acceleration, rotor braking, treatment time, treatment programs, signaling of operating errors, and signaling of imbalances and for selecting rotor type, receptacle type and radial values of a rotor.

11. The control device of claim 10, further comprising an acoustic signal associated with each said change of setting.

12. The control device of claim 10, wherein said control switch is positioned substantially centrally below said display panel.

13. The control device of claim 11, wherein said control switch is positioned substantially centrally below said display panel.

14. The control device of claim 1, further comprising an acoustic signal associated with each said change of setting.

15. The control device of claim 14, wherein said control switch is positioned substantially centrally below said display panel.

16. The control device of claim 1, wherein said control switch is positioned substantially centrally below said display panel.

17. A control device for a laboratory centrifuge, said control device comprising:

a display panel for displaying a visual representation of operating commands for a laboratory centrifuge;

a control switch for setting an operating command, said control switch being capable of at least two independent movements, a first of said movements comprising a rotation about an axis and a second of said movements comprising a displacement along the axis;

wherein said display panel is configured to display at least one menu configuration of operating commands; and

wherein one of said movements provides for selection of and also change in setting of said operating command and another of said movements provides for acceptance of said selection and also acceptance of said setting.
