Performance Menu Item Descriptions
The following sections describe each menu item in detail.
Elevation Gains (Raise and Lower)
Elevation Gains (Figure 55) determines the speed at which your Topcon P-32+ or P-32 System allows the tow
point cylinders to adjust to a change in elevation. For faster hydraulic response, increase the gain value. For
slower hydraulic response, decrease the gain value.
The objective is to set the gain so the screed reacts to the change in grade quickly, but without “overshooting”
the new elevation.
• Gain Elevation Value Range: 1-200
• Factory Preset: 25
Press Enter Turn Grade Adjustment Knob Press OK
If power is interrupted to the Control Box within two seconds after making an adjustment, the
Control Box does not have time to store the new setting and reverts to previous (or original) settings.
Before setting the Elevation Gain, make sure the machine's hydraulic flow controls valves are
adjusted for proper cylinder speed according to the manufacturer's recommendations.
