Abstract
Operating values of an electronic operating system (2), e.g., power switch or motor drive, are parameterized with a hand-held control device (6) with a display device (10) for displaying operating parameters via transmission means (5) to a data store (31) of the hand-held control device (6) following connection of the latter to the operating system (2). A microprocessor circuit (25) in the hand-held control device (6) facilitates the detection of altered operating parameters and the transfer of those altered parameters back to the control unit (3) of the operating system (2).
Claims5
Manual operation apparatus (6) for connection to a control unit (3) which is designed as a trip unit and is provided for an electric device such as a circuit breaker (2) or a motor drive, the control unit having a programmable memory circuit (36) for storing performance characteristics, and the manual operation apparatus (6) having a display device (10) for displaying performance characteristics transmitted from the control unit (3) by a transmission means (5) to the manual operation apparatus (6) and being provided with an electronic data memory (31) for storing the performance characteristics transmitted from the control unit (3) and a microprocessor circuit (25),
- characterized in that the manual operation apparatus (6) has a keypad (11) for creating altered performance characteristics and for storing these altered performance characteristics in the electronic data memory (31), and the altered performance characteristics can be transmitted from the electronic data memory (31) to the control unit (3) of the electric device over the transmission means (5).
Method of parameterizing performance characteristics of an electric device using a manual operation apparatus (6) according to one of the preceding claims,
- characterized by the following steps:
- connecting the manual operation apparatus (6) to the device (2),
- reading out and displaying on the display device (10) the performance characteristics stored in the memory circuit of the control unit (3),
- storing the data corresponding to the performance characteristics thus read out under a selectable address in the data memory (31) of the manual operation apparatus (6),
- altering at least one performance characteristic by entering at least one command on the manual operation apparatus (6),
- transmitting the altered performance characteristic to the control unit (3) and acknowledging the completed transmission to the manual operation apparatus, and
- disconnecting the manual operation apparatus (6) from the device (2).
Method of parameterizing performance characteristics of an electric device (2) using a manual operation apparatus (6) according to one of the preceding claims,
- characterized by the following steps:
- connecting the manual operation apparatus (6) to the operational means (2),
- reading out and displaying on the display device (10) the performance characteristics stored in the memory circuit of the control unit (3),
- storing the data corresponding to the performance characteristics thus read out under a selectable address in the data memory (31) of the manual operation apparatus (6),
- disconnecting the manual operation apparatus (6) from the device,
- altering the performance characteristics by using the application program,
- reconnecting the manual operation apparatus (6) to the same device or an identical device and transmitting the altered performance characteristics to the electronic control unit (3) of the device.
