AutoSet User Manual 1137200
Operation 4-3
Using these reference tonnages, setpoints for left and right strain links are calculated as follows:
High setpoint left = 38 tons + (38 tons x .15) = 38 + 5.7 = 43.7 tons
High setpoint right = 30 tons + (30 tons x .15) = 30 + 4.5 = 34.5 tons
Repeatability setpoint left = 38 tons x .05 = 1.9 tons
Repeatability setpoint right = 30 tons x .05 = 1.5 tons
AutoSet displays the results of its setpoint calculations in the Setpoints LED displays on the
front panel. Two setpoints are shown for 1500 and 1500 Plus AutoSets, four setpoints for
1504 and 1504 Plus units.
Only high setpoints are displayed on standard AutoSet 1500 and 1504 units. On AutoSet
1500 Plus and 1504 Plus models, either high or repeatability setpoints are displayed,
depending on the position to which you set the DISPLAY switch (i.e., “HIGH” or
“REPEATABILITY”).
AutoSet calculates new setpoints whenever the RESET button is depressed for at least two
seconds (1500 and 1504 AutoSets) or the DISPLAY switch is turned to “RESET” and held for
at least two seconds (1500 Plus and 1504 Plus units). Setpoints are displayed after the sample
period is completed. AutoSet also calculates new setpoints whenever you change the percent
high tolerance or percent repeatability tolerance setting.
On AutoSet 1500 Plus and 1504 Plus units, both high and repeatability setpoints are active
while the press is running regardless of the DISPLAY switch setting. Setpoints can be
recalculated even when the press is running.
AutoSet uses the settings you specify for percent high tolerance and percent repeatability
tolerance to calculate setpoints for all dies used on the press. If you want different settings
used for individual dies, you must change settings. See
Changing Setpoint Percentage
Settings , page 4-12.
Setting the Sample Period
The sample period is the number of strokes during which AutoSet collects tonnage values to
use in calculating setpoints for high tonnage and, in AutoSet Plus units, repeatability. You
can select one of two sample periods–1 stroke or 15 strokes.
As a rule of thumb, use the 15-stroke sample period when running in Continuous mode or
when the percent high tolerance setting is less than 50% or the percent repeatability setting is
less than 25%.
Use the 1-stroke sample period when the percent high tolerance setting is greater than 50% or
the percent repeatability setting is greater than 25%.
15-STROKE SAMPLE PERIOD YIELDS GREATER TONNAGE ACCURACY
If you are unsure which setting to use, set the sample period to 15 strokes. The 15-stroke setting
yields more accurate tonnage readings. The 1-stroke setting is used mainly for convenience in
low-tolerance jobs.
