SHORTED SCR CYCLE LIMIT:
(
T03300 only
)
(3–99)
This parameter sets the maximum number of consecutive cycles
where a shorted SCR condition (without current) can occur before
the breaker is tripped.
WARNING!
If the control detects a shorted SCR condition
with current for four out of seven half-cycles,
the control will trip the breaker regardless of
the programmed value of this setup parameter.
Refer to the description of these features in
“SCR Short Detection” on page 7-10.
DATA COLLECTION SAMPLE SIZE: n
(1–99)
DATA COLLECTION SAMPLE
FREQUENCY: nnnn (1–9999)
These two parameters set a global command which allows the weld
control to sample data for analysis at controlled intervals.
The sample size is the amount of weld data collected for analysis
(number of consecutive welds, per bin). The sample frequency is
the total number of welds (per bin) where data is collected (the
samples are taken from). See “SPC Indexing Capabilities” on page
7-8 for more information.
TIPS DOWN VERIFIED CURRENT: nnnn
(T03300 0nly)
(0–9999)
This is the value of current that is used as the threshold when the
control executes the functions VERIFY TIPS DOWN nn CY. nn
TIMES or SLOW CYLINDER TEST EVERY nn CYC. nn TIMES.
Determine this value by experimenting to distinguish open and
closed secondary currents for various heat settings.
For more information, refer to the description of this parameter in
“Dynamic Squeeze Features” on page 7-6.
TRANSFORMER TURNS RATIO: nnn:1 (1–256:1)
This parameter tells the control the turns ratio of the welding
transformer used. This lets the control determine secondary current
during a weld. (Secondary current equals the primary current
multiplied by the turns ratio.)
