1137200 AutoSet User Manual
4-10 Operation
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 repeatability and high tolerance settings for an AutoSet 1500 Plus or
1504 Plus load analyzer, do the following:
1.
Inside the AutoSet enclosure, turn the “% REP” indicator dial on the AutoSet processor
board to position 4 (i.e., 5%), referring to
Setting the Percent Repeatability Tolerance
(AutoSet Plus Only) , page 4-6. Then, turn the “% TOL” dial also to position 4 (i.e., 15%),
referring to Setting the Percent High Tolerance , page 4-5.
2.
Turn the DISPLAY switch on the AutoSet front panel to the RESET position and hold 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.
If you are operating in Single-stroke mode, start and cycle the press until the sample
period is completed and AutoSet displays new values in the Setpoints displays; then cycle
the press for a few additional strokes.
High tonnage setpoints are displayed when the DISPLAY switch is turned to the HIGH
position. Repeatability setpoints are displayed when the DISPLAY switch is turned to the
REPEATABILITY position.
4.
If AutoSet stops the press after the new setpoints have been calculated due to a
repeatability fault (indicated by a flashing channel Load display and the abbreviation
“rEP” appearing in the corresponding Setpoints display), do the following:
a. Establish that the press stopped due to low setpoints by checking for malfunctions
such as a stuck part, load imbalance, misfeed, etc.
b. If the press stopped because repeatability setpoints were too low, turn the “% REP”
indicator dial up to position 5 (i.e., 7%), and repeat steps 2 and 3.
c. If AutoSet stops the press again, turn the “% REP” dial to the next higher setting, and
repeat steps 2 and 3. Repeat this step until the “% REP” setting is high enough so that
AutoSet does not stop the press.
PRESS STOPPED DUE TO TONNAGE FAULT
If the press was stopped due to a tonnage fault rather than a nuisance stop (i.e., setpoints
that have been set too low), do not continue with this procedure until you have corrected
the problem. Otherwise, damage to the press and tooling may result.
Failure to comply with these instructions could result in property damage.
