CYL: (AIR-NORMAL)
(AIR-INVERTED)
This setup parameter defines what type of weld gun cylinder is
being used:
•
AIR-NORMAL
—Select this type of cylinder when the
machine uses an air-only cylinder, AND
the RETRACT output
is turned OFF to close the gun.
•
AIR-INVERTED
—Select this type of gun cylinder when the
machine uses an air-only cylinder, AND
the RETRACT output
is turned ON to close the gun.
WARNING!
For safety, the MedWeld 4000 ignores any
changes made to this parameter, until you
reset the control (by cycling power).
HIGH POWER FACTOR LIMIT (%): 99 (10–99)
LOW POWER FACTOR LIMIT (%): 10 (10–99)
(T03300 only):
These two parameters tell the weld control the
range of acceptable values for power factor. If the power factor
exceeds or falls below these limits, a HIGH or LOW POWER
FACTOR LIMIT fault is generated.
The HIGH POWER FACTOR LIMIT fault can help warn of a
deteriorating secondary. A LOW POWER FACTOR LIMIT fault
can indicate a control malfunction, or an increase in inductive
resistance.
NOTE:
The function
POWER FACTOR LIMIT: HI= NN% LOW= NN%
will
override the
High
and
Low Power Factor Limit
setup parameter if
programmed in a weld schedule.
TIPS DOWN TEST FIRE %%I:
(
T03300 only
)
20 (20–99)
The welding schedule uses this value of heat when the control
executes the functions VERIFY TIPS DOWN EVERY nn CYC. nn
TIMES or SLOW CYLINDER TEST EVERY nn CYC. nn TIMES.
Program the lowest value possible to reduce the open secondary
voltage, while keeping this value high enough so that the current
detected when tips are down exceeds the Tips Down Verified
Current setup parameter.
For more information, refer to the description of this parameter in
“Dynamic Squeeze Features” on page 7-6.
