PROGRAMMING GENERAL DESCRIPTION
Programming of the Legend Plus is done through the front panel keypad, which
allows the user to enter into Main Menus, Sub-Menus, and Edit Menus. English
language prompts, flashing parameter values, and the front panel keypad aid the
operator during programming.
Although the unit has been programmed at the factory, the parameters generally
have to be changed to suit the desired application. The Main Menus are entered by
pressing the enter (ENT) key when Program Mode is displayed. From Main Menus,
the user can enter a Sub-Menu where parameter values can be viewed. From the
Sub-Menu, the operator can advance into an Edit Menu, where a parameter value is
changed and entered. There are three types of Edit Menus:
1. A Choice Edit Menu allows the operator to scroll through options by repeatedly
pressing the down arrow key until the desired option is viewed. The option is
selected by pressing the ENT (enter) key, which returns the operator to the previous
sub-menu. The operator can exit the Edit Menu WITHOUT making a selection by
pressing the <ESC key, which returns the operator to the previous sub-menu.
2. In a Numerical Value Edit Menu, the operator uses the left or right arrow key to
select a digit. The up and down arrow keys change the digit’s value. The PRS key
toggles the left-most digit between a minus (-) and a zero for plus (+), for that
numeric value. When the appropriate numerical value is selected, it is entered by
pressing the ENT key, which returns the operator to the previous sub-menu.
3. A Text Edit Menu is where messages are programmed, and changes are made to
mnemonics and custom display lines. The up and down arrow keys are used to scroll
through characters. The function keys are used with the up and down arrow keys to
toggle between upper and lower case letters and to toggle between standard and
extended character sets. A complete listing of key functions in a Text Edit menu can
be found in the Program Message Module.
All parameter values changed in the Programming Loop are saved when exiting the
loop. The operator can exit the programming loop from any of the main menus by
pressing the <ESC key. When the <ESC key is pressed, the display momentarily shows
“Please Wait...”, while the parameter values are saved in non-volatile memory. The unit
returns to the indication display that was last viewed. Shown are the Main Display Loop
and the Main Programming menus of the Multi- Preset Legend Plus (LGPM) unit.
All following flow charts have slanted characters to show parameters that are
flashing in the unit’s display and have programmable options.
