Determining the Correct High Tolerance Setting
(Standard AutoSet)
The purpose of this procedure is to determine the lowest high tonnage setpoint at which
AutoSet will not stop the press. The “% TOL” indicator dial must be set high enough to avoid
nuisance stops, which occur when normal variations in tonnage cause AutoSet to stop the
press, but not so high that the press is vulnerable to tonnage overloads.
The percent high tolerance setting must be capable of initiating a tonnage fault for any load
that can potentially damage the press. A tonnage fault can be caused by a stuck part,
significant change in material thickness or hardness, slug stacking, load imbalance, misfeed,
broken punch, end of stock, or any die malfunctions.
To determine the correct high tolerance setting for a standard AutoSet 1500 or 1504 load
analyzer, do the following:
1.
Inside the AutoSet enclosure, turn the “% TOL” indicator dial on the AutoSet processor
board to position 4 (i.e., 15%), referring to
Setting the Percent High Tolerance , page 4-5.
2.
Press the RESET button on the AutoSet front panel for at least two seconds to instruct
AutoSet to recalculate setpoints when the press is restarted.
The Setpoints displays flash and the setpoint readings change to values that are 120% of
the full-scale tonnage of the press.
3.
If you are operating in Continuous mode, start and run the press until the sample period is
completed and AutoSet displays new values in the Setpoints displays; then run the press
for an additional 20 strokes.
DISABLING SETPOINT CALCULATION
When the “% REP” indicator dial is set to “0,” the repeatability setpoint calculation function
is disabled and AutoSet does not create repeatability setpoints. With a zero (“0”) setting,
your press is not protected against repeatability faults; however, AutoSet will stop the
press if the load exceeds 120% of the full-scale tonnage. If you have not disabled high
tonnage setpoints, AutoSet will stop the press if the tonnage exceeds the high tonnage
limits.
ERRATIC TONNAGE AT STARTUP
If you have not installed a zero cam, your standard AutoSet 1500 or 1504 unit may
generate erratic tonnage readings as the press is starting up due to vibration and noise.
To prevent these inconsistencies from influencing the accuracy of calculated setpoints,
press the RESET button to initiate recalculation of setpoints
after the press has completed
its startup routine and tonnage has stabilized.
You can eliminate erratic tonnage readings by installing a zero cam (see
Installing a Zero
Cam , page 2-16).
