SECTION 5 – PROGRAMMING
5-1. General
A. Displays
The displays presented by the microprocessor control either provide information to the user, or allow the user to enter infor- mation needed for program execution. The displays vary from mode to mode. Within each mode, the displays are always shown in the same sequence.
Pressing the Right/Increase push button allows the user to move forward through the sequence of displays, beginning to end. Pressing the Left/Decrease push button allows the user to move backward through the displays. Either push button can be used to access displays.
B. Selecting And Defining A Parameter
The user defines a parameter by entering a value for it. This is normally a
1.Press Parameter Select (see Section
2.Press Right/Increase (see Section
3.Press Parameter Select again to deselect the parame- ter (the parameter stops flashing). If the display contains more than one parameter, the next parameter will be selected.
Parameters are always selected in sequence. If the existing value for the first parameter is acceptable, but another param- eter needs to be changed, use the Parameter Select push button to select and deselect the first parameter without changing its value. The next display in a mode cannot be ac- cessed if a parameter remains selected (flashing) in the existing display.
C. Defining Program Number
In some displays, the first parameter is the program number. This number provides a means of identifying programs en- tered into the selected mode. Since parameters are selected in sequence, even when the program number is not being changed it must be selected and deselected before the next parameter can be changed.
The program number is normally defined in the first display used to enter information. The defined number carries over to the following displays and does not need to be redefined as long as the original defined number applies.
To avoid unnecessary repetition, this manual does not indicate that the program number can be redefined in each display con- taining it. It is assumed that when a program is entered, each display in sequence applies to the same program.
D. Display Representation
When the microprocessor control’s digital display is repre- sented in this Owner’s Manual, an “X” is used to represent a parameter whose contents may vary, as shown in the following example:
T H E | A D J U S T M E N T L I M I T |
I S | + O R – X X A M P S |
|

E. Initial Displays
Each time power is applied to the microprocessor control or a reset is initiated on the Program/Run/Reset keyed switch (see Section
1.The first initial display identifies the welding power source and microprocessor control. The display shows:
* S Y N C R O W A V E 3 5 1 *
M P C M O D U L E
The next display scrolls into view.
2.The second initial display indicates the part number of the software program contained in the unit, and the re- vision level of the program. The display shows:
P A R T | # X X X X X X |
R E V I S | I O N L E V E L X |
|
|
The next display scrolls into view.
3.The third initial display indicates the copyright for the program in the unit. The display shows:
C O P Y R I G H T 1 9 9 3
M I L L E R E L E C T R I C M F G .
The next display scrolls into view.
4.The fourth initial display indicates the amperage ad- justment limits that have been defined (see Section
T H E | A D J U S T M E N T L I M I T |
I S | + O R – X X A M P S |
|
|
The repeating displays scroll into view.
F.Repeating Displays (Ready Condition)
After the initial displays are shown, repeating displays are shown. These displays scroll continuously until the operator takes action. The presence of the repeating displays indicates that the microprocessor control is ready for a program to be en- tered, or for a program to be executed.
