| For cushions this should be the maximum operating pressure specified by the |
| cushion manufacturer. |
| For hydraulic overloads this value should be the pressure specified by the press |
| manufacturer for rated tonnage operation. |
Min. Pressure | This value should be set to the minimum operating pressure at which you will |
| operate your counterbalance, cushion, or hydraulic overload. |
| For counterbalances, this value is the pressure that balances the slide with no |
| tooling and cannot be set below 5 psi. Obtain this value from the press |
| counterbalance table or press manual. |
| For cushion(s), the Min. Pressure should be set to at least the value that just barely |
| supports the weight of the cushion cylinder. This can be found by slowly |
| increasing the pressure to the cushion until it just starts to rise. Then back off the |
| pressure until it just starts to fall. The Min. Pressure should be set to at least the |
| average of the two pressures. The Type “B” and “C” valve systems may be used |
| to provide a minimum pressure through their manual regulator. This keeps the |
| cushion from falling due to air leakage when the control is powered off and |
| prevents cushion pins from falling through the lower die shoe and bolster. |
| NOTE! Cushions can always drift down when the plant air supply is off. |
| Also, If a type “B” valve is used, Min Pressure must be set above the manual |
| regulator setting. |
| For hydraulic overloads, the Min. Pressure should generally not be set to less than |
| 25% of the Max. Pressure value. |
Max. Die Weight | This parameter only appears when a counter balance is being configured. |
| This should be set at the die weight the counterbalance handles at its maximum |
| pressure. Obtain this value from the press counterbalance table or press manual. |
| Note that the units to the right of this parameter are also configurable. When the |
| editing cursor is placed on these units, softkey 1 will read “CHANGE UNIT”. |
| When pressed, pounds, kilograms, tons, or metric tons may be selected from a list. |
| Note that changing the unit here will also change the unit for Min. Die Weight. |
Min. Die Weight | This parameter only appears when a counter balance is being configured. |
| Set this value to 0 die weight. (This represents no tooling on the upper slide at the |
| minimum counterbalance pressure). Note that the units to the right of this |
| parameter are also configurable. When the editing cursor is placed on these units, |
| softkey 1 will read “CHANGE UNIT”. When pressed, pounds, kilograms, tons, |
| or metric tons may be selected from a list. Note that changing the unit here will |
| also change the unit for Max. Die Weight. |
Display Weight As | This parameter only appears when a counter balance is being configured. |
| Set this parameter to the units that die weight should be displayed in. The choices |
