Display And Keypad (1) Display (2) Keypad (3) Function key (4) Scroll down key (5) Scroll up keyNote: For a list of parameter codes and the corresponding range of values, see System Operation, "Parameters".Display (1) and keypad (2) are used to select and manipulate parameter values that control the operation of the digital voltage regulator. Display (1) of the digital voltage regulator has four digits. A colon in the display indicates that the number showing is a parameter code. If a colon is not present, then the number showing is a parameter value. A decimal point in the display is used to indicate the precision of the parameter value.Keypad (2) has three keys. The keys are listed below.
Function key (3)
Scroll down key (4)
Scroll up key (5) Display (1) has two modes, parameter code mode and parameter value mode. Function key (3) is used to toggle back and forth between the two modes. Scroll down key (4) and scroll up key (5) are used to decrease and increase the parameter number or value number that is showing on display (1).

0101 The operation of display (1) and keypad (2) can be described as a table. Pressing function key (3) toggles the display back and forth between the two columns of the table (parameter code and parameter value). If a colon is present, the display is in parameter code mode. If a colon is not present, the display is in parameter value mode.Pressing a scroll up key (5) or scroll down key (4) will increase or decrease the display to the next number within a column. Use of the scroll keys cannot cause the display to change columns of the table.In order to configure a parameter code (change the value), follow the procedure below.
Select the desired parameter code by pressing scroll key (4) or (5) .
Access the parameter value by pressing function key (3) .
Select the desired parameter value by pressing scroll key (4) or (5) .
Enter the chosen value into the memory of the digital voltage regulator by pressing function key (3) .Example

Example Illustration - Display Shows Parameter Code Of :01 (1) Display (2) Keypad (3) Function key (4) Scroll down key (5) Scroll up keyThis example is a demonstration of scrolling and selection of parameter codes. Also the scrolling and configuration of values is demonstrated.After the digital voltage regulator is powered up (battery voltage applied) parameter code ":01" is shown on the display. The engine does not have to be running for the digital voltage regulator to show parameter codes. The colon indicates that a parameter code is being shown.The user has the option of pressing function key (3), scroll down key (4), or scroll up key (5) .If scroll up key (5) is pressed, the display moves (scrolls) up to the next parameter code, ":02". Again, the colon is on. This is the
