LIMIT SETTING
Each user memory can be optionally configured to limit
the user’s range of control over some user interface set-
tings. By default, user limits are not enabled. To set lim-
its for a selected memory, first select a weld mode and
perform a memory save. Next, press and hold the mem-
ory button for five seconds. Release the memory button
when the memory LED begins to blink rapidly and the
Mode Select Panel displays indicate "Set Limits".
If the pass code has been set to a value other than zero,
the user will be prompted to enter it. If the pass code is
zero, the Mode Select Panel will immediately display the
Limit Setup menu and the SETUP LED will illuminate:
The above example shows a wire mode, constant current
weld modes would show "Weld Amps" rather than "Weld
WFS".
There are four items displayed on each Limit Setup
screen. The long alphanumeric display shows the select-
ed attribute (e.g. Weld WFS,Volts, etc.). The short
alphanumeric displays show the selected attribute’s high
and low user limits. The 7-segment displays show the
value that is copied to procedure memory when a memo-
ry recall is performed.
One of these four items will blink to indicate which item
will change when the Mode Select Panel Knob is rotated.
Initially, the selected item will be the attribute. To select
the high limit, press either Mode Select Panel button and
the high limit value will begin to blink. Pressing either
Mode Select Panel button again will cause the memory
value to blink, pressing a third time will cause the low limit
to blink.
Weld modes cannot be selected from the Limits Setup
menu; the mode must be selected and saved to memory
prior to entering the Limits Setup menu.
The memory value, high and low limit values are bound by
the limits of the machine. For example, weld mode 49
may allow the wire feed speed to be adjusted between 10
and 200 in/min. These are referred to as "machine limits".
Machine limits can vary between power sources and are
also weld mode dependent.
The memory value must always be less than or equal to
the high limit and greater than or equal to the low limit.
The high limit must always be greater than or equal to the
low limit and the low limit must always be less than or
equal to the high limit. The rules are enforced automati-
cally. If the low limit is increased above the memory
value, the memory value will automatically increase.
To lock an attribute to a specific value, set the high and
low limits to the desired value. The user will not be able
to change it.
After setting limits, press the memory button that is flash-
ing. The Mode Select Panel displays will prompt the user
to save or discard the limit changes just made.
By pressing the Mode Select Panel button labeled YES,
changes to limits are saved and user limits are automati-
cally enabled. By pressing NO, any changes made to lim-
its are discarded and the limit enable/disable state is not
changed.
To enable or disable limits that have been established for
any memory, press and hold the respective memory but-
ton in for more than 10 seconds until the Mode Select
Panel displays "Enable Limits?" Pressing "Yes" will use
the established limits, while pressing "No" will ignore the
established limits. The limits that have been set for any
memory location will not be erased if they are disabled.
