3-12 Calibration
6.
Lower the ram 0.003” or 0.004” (0.076–0.102 mm) with your press’s shut height
adjustment, lock the shut height, and cycle the press again.
7.
Repeat step 6 until the readout on your calibration unit indicates that contact on the load
cell(s) is being made at BDC.
8.
Continue to cycle the press and adjust the ram downward, locking the shut height after
each adjustment, until the Load LED displays on your calibration unit show the tonnage
you determined in step 4.
If you are using two load cells, make sure both Load LED readouts display equal tonnage.
If Load readings disagree by more than ± 2%, add shim stock to the load cell that shows
the lower tonnage. Cycle the press, and recheck tonnage. Continue to add shim stock
until the tonnage shown in both Load displays is equal.
Check to make sure that the load cells, shims, and parallels do not move during
calibration, using adhesive tape or equivalent, if necessary, to hold them in place. If you
reposition any of these items, make sure to double-check the tonnage shown on the Load
LED display(s) on the calibration kit before proceeding with the next adjustment.
Setting Full-scale Tonnage on Your AutoSet
To set your AutoSet to the full-scale tonnage of your press, which is currently being applied to
the load cells connected to the calibration unit, do the following:
1.
Open the cover of the AutoSet control enclosure, and locate the three dial indicators
labelled “TONNAGE” (S103, S104, and S105) at the upper right of the AutoSet processor
board (see Figure 3-7, page 3-13).
Each dial indicator has an arrow you can turn, using a small screwdriver, to the numerical
setting you want. Indicator S3 represents the hundreds position in the full-scale tonnage
setting, indicator S4 represents the tens position, and indicator S5 represents the ones
position. Dial indicators are factory-set to 200 tons, as illustrated in Figure 3-7, where
indicator S103 is set to “2,” and indicators S104 and S105 are set to “0.”
DO NOT STICK PRESS ON BOTTOM
Do not overload the press by lowering the ram too quickly. You may stick the press on the
bottom. Increase the load gradually. Unlike the softer material used for making parts, load
cells are extremely stiff and provide no compressive cushion to bring the ram through
bottom dead center if you over-adjust.
Failure to comply with these instructions could result in property damage.
Wintriss recommends that AutoSet be calibrated at the tonnage at which the press will normally
operate. If you usually run between 60-90% of press capacity, calibrate at 75% of capacity. For
example, if the press is a 100-ton press, calibrate for 75 tons. Do not calibrate at less than 50% of
press capacity.
