15.
Move the lever on switch S3 or S2 to the “OPERATE” position. Both left and right
channel Load LED displays should now read zero (0) tons.
16.
Locate the Percent Tolerance Selector dial, labelled “S2” on old-style boards (see
Figure 3-2) and “S7” on new-style boards (see Figure 3-3).
Locate the Percent Repeatability Selector dial, labelled “S8” on old-style boards (see
Figure 3-2) and “S6” on new-style boards (see Figure 3-3).
Set both dials to the zero (0) position, then reset the unit by pressing the RESET button or
turning the DISPLAY switch on the AutoSet cover to “RESET,” making sure to release
the button or switch immediately.
Setting both percent tolerance selector dials to zero (0) disables AutoSet’s automatic
setpoint function.
Applying Full-scale Tonnage to the Calibration Kit
To apply full-scale tonnage to the AutoSet 1500 calibration kit, perform the following steps:
1.
Make sure that the die is removed from the press and that any bolster/bed openings or ram
holes are covered with a plate or plates rigid enough to prevent flexing. Wintriss strongly
recommends using 1”- to 2”-thick steel plates, or parallels, above and below the load cells
to distribute the load more evenly on the bed and ram. Even load distribution helps to
improve calibration accuracy and linearity (see
Checking Linearity , page 3-19).
2.
Bring the ram to bottom dead center (BDC) and turn off power to the press. Use a dial
indicator, if necessary, to make sure that the press is at 180°.
3.
Place the load cell(s) and parallels under the connecting rod(s). Make sure load cells are
centered under the connecting rods to ensure even load distribution on the press frame.
4.
Determine the load you will put on the load cells. This value should be equal to the
tonnage you normally use when making parts. For example, if you usually run between
60–90% of press capacity, then calibrate the press at 75% of capacity. This setting will
yield the most accurate tonnage readings within this range. Make sure that you do not
calibrate the press at less than 50% of capacity. Also, make sure not to exceed press
capacity.
5.
Power up the press, and cycle the press through one stroke.
Setpoints LED displays will show numeric readings after the unit is reset. Ignore these
readings. Only the Load LED displays are used in calibration.
DO NOT STOP THE RAM ON THE LOAD CELLS. ALWAYS CYCLE THE PRESS
THROUGH A COMPLETE STROKE.
