Abstract

A controller for a voltage regulator has an input keypad for designating selected operating parameters of the voltage regulator. The keypad is formed with a dedicated function portion and a menu navigation portion, and the parameters are divided into first and second categories. The controller has a display for displaying the parameters, and a computer is connected to the input and to the display for controlling the display in response to activation of the keypad. Any parameter in the first category can be displayed on the display by activation of the dedicated function portion of the keypad. Any parameter in the second category can be displayed by activation of the menu navigation portion. The menu navigation portion can optionally also be used to control display of parameters in the first category.

Claims

1. A method for displaying operational parameters of an electrical power distribution mains system step voltage regulator comprising:

selecting for display on an electronic display device a first operational parameter by actuating a dedicated input key assigned for displaying the first parameter; and

selecting for display on the display device a portion of less than the whole of operational parameters set forth in a plurality of display menus by actuating menu navigation keys which cause the portion of operational parameters to be scrolled through the display.

2. A method for controlling an electrical power distribution mains system voltage regulator, the method comprising the steps of:

providing an input keypad for designating selected operating parameters of the electrical power distribution system voltage regulator, the input keypad being formed with dedicated function keys for display of specific voltage regulator operational information and menu navigation keys for selecting for display a portion of less than the whole of a plurality of menus of operational parameters and the parameters being divided into first and second categories, respectively;

providing a display for simultaneously displaying only a portion of less than the whole of all of the parameters; and

at least one of;

activating the dedicated function keys to display parameters in the first category; and

activating the menu navigation keys to select for display only a portion of less than the whole of the parameters in the first or second category.

3. Apparatus for controlling an electrical power distribution mains system step voltage regulator, said apparatus comprising:

an input device for designating for display selected operating parameters of the electrical power distribution mains system step voltage regulator, said input device having a dedicated function portion and a menu navigation portion, and said parameters being divided into first and second categories, respectively;

a display for simultaneously displaying only a portion of less than the whole of all of said first and second category parameters; and

a computer connected to said input device and said display for controlling said display in response to activation of said input;

said apparatus being constructed so that any parameter in said first category can be displayed on said display by activation of said dedicated function portion and any parameter in said second category can be selected for display on said display by activation of said menu navigation portion.

4. Apparatus according to claim 3 wherein any parameter in said first category can be displayed on said display by activation of said menu navigation portion.

5. Apparatus according to claim 3 wherein said display comprises a display screen.

6. Apparatus according to claim 3 wherein said display comprises an LED display.

7. Apparatus according to claim 3 wherein said input device comprises a keypad.

8. Apparatus according to claim 3 wherein said input device comprises a keypad, said dedicated function portion comprises a plurality of keys physically grouped together in a first area of said keypad, and said menu navigation portion comprises a plurality of keys physically grouped together in a second area of said keypad.
