Detailed description of the invention
Fig. 1 is the block diagram that the long range regulation apparatus 1 of the switchgear parameter for regulating industrial switch gear is connected with the adjustment device 20 of the switchgear parameter for equipment itself and display 15 place. These switchgear parameters such as could be for the threshold value of overload triggering or short circuit current triggering and can be transferred on industrial switch gear by long range regulation apparatus 1, or directly regulating in device 20 original position, generally it is conditioned when using manual adjustments additional device 5, such as screwdriver. At this, regulate and act directly on adjustment device 20. In display 15, the parameter value of display reads and is transferred to from regulating device 20 display 15. For this, adjustment device 20 has a device for readout. This device can be the overall building block regulating device 20. Described value only can read once when value changes or read with the frequency determined. At this, can so select described frequency so that read and essentially continuously carry out and be output on display 15 so that the change of value is traceable on a display 15.
