Weld ON/OFF When the
WELD ON/OFF
entry (in the
Extended System Values
screen) is set to
LOCAL
, pressing this pushbutton switch will enable or disable the flow of weld
current. The green LED lights when current is enabled. When current is disabled,
the Control can still sequence through its program and fire valves, but current will

- Data +
ON | OFF This is a two-position pushbutton switch. When the Control is in the
Program
Mode, pressing this pushbutton switch will allow the operator to change the program
settings. Holding the switch down (in either position) will scroll the values in the
selected direction.
When the Control is in the Run mode, the
WELD ON/OFF
switch is set to
OFF
, and
the cursor is at the schedule number position, the operator can use this key to scroll
through the schedules.
Cursor This is a four-position, momentary-action pushbutton switch. Pressing this
pushbutton switch will allow the operator to move the cursor around the display.
Left and Right Arrows – In general, the right arrow will move the cursor
from left to right, then to the left-hand field of the next line down, across that line,
and so on. Upon reaching the bottom, right-hand field, the cursor will “roll over” to
the top, left-hand field. The left arrow works in the reverse direction. Whichever
arrow is pressed, when the cursor enters a field, it will automatically position itself at
the rightmost position of a numeric field or the leftmost position of an
ON/OFF
or
alphabetic field.
When in a numeric field, successively pressing the left arrow will move the cursor
successively to the next higher order digit or, when the highest order number for that
field is reached, to the previous field.
Up and Down Arrows – These arrows will move the cursor to the field above
or below the current field whose rightmost digit is closest to the current position of
the cursor. Holding any cursor pushbutton down will cause the cursor to rapidly
move in the appropriate direction, eventually rolling over from the last field to the
first, or vice-versa.
While in Program Mode, when the cursor is in any position of a digit field, pressing
the + or – key of the
DATA
pushbutton will cause the digit in that position to
increment or decrement by one digit.

WELD ON/OFF
pushbutton switch is set to
OFF
, pressing this pushbutton
switch will cause the current Schedule number’s screen to be displayed. The cursor
shall be at the unit digit of the Schedule #. If the Schedule # is changed, that specific
schedule will be displayed. See Chapter 3 for details of this screen.
Valves When the
WELD ON/OFF
pushbutton switch is set to
OFF
, pressing this pushbutton
switch will cause the Valve screen to appear on the display. See Chapter 3 for
details of this screen.
