PUMP SETUP SCREEN

Pump parameters are input and viewed on the Pump Setup screen (Figure 4-19), which is

accessed from the Setup screen. Information keyed in from the pump and drive motor operating

specifications is used by the control system to calculate pump flow rate relative to motor speed

and autotune the pump motor to its controlling VFD. Accurate information for the specific pump in

use is critical for proper operation. Typically, a flow curve is required to obtain the pump output

per revolution parameter.

conveyor to remove accumulated process material that is impeding rotation. With this screen

displayed, the operator selects the desired bowl and conveyor RPMs for the cleanout process.

During cleanout, the actual RPMs and torque percentages are displayed below the setpoints.
