PROGRAMMING GENERAL DESCRIPTION
Programming 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. From the
Indication Display Module, the Programming Module is entered by pressing
the Program/Enter (PGM/ENT) key. This displays “PROGRAM MODE”.
Then press the Select (SEL) key to enter the Programming Module. The Up
and Down arrows are used to scroll through the main menus. Pressing Select
(SEL) from a main menu, allows the user to enter a Sub-Menu where
parameter values can be viewed. Parameter values are changed and entered
in the Edit Menu. There are two types of Edit Menus:
1. A Choice Edit Menu allows the operator to scroll through options by
pressing the down arrow key until the desired option is viewed. The option
is entered by pressing the PGM/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
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. When
the appropriate numerical value is selected, it is entered by pressing the
PGM/ENT (enter) key, which returns the operator to the previous sub-menu.
All parameter values changed in the Programming Module are saved
when exiting the Module. The operator can exit the Programming Module
from any of the main menus by pressing the
blanks the display while the parameter values are saved in non-volatile
memory. Turning off power before exiting the Programming Module causes
a loss of the new data values entered, and “CHECKSUM ERROR 1” appears
on the display at the next unit power up. Press “ENT” then “SEL” to reenter
the new values. The unit returns to the Indication Display that was last
viewed. Shown at right is the Indication Display Module and the Main
Programming Menus of the MDC unit.
