2.
Start the pump by clicking the “Start Pump” button. The pump will ramp up to the speed in the “Pump
Rotation Speed” box and hold there independent of flow or pressure on the pump. If a different rotation
speed is desired, it is not necessary to stop the
pump first, the number in the “Pump Rotation Speed” can be
changed while the pump is operating. The pump will only go to the new desired speed once the “Apply”
button has been clicked.
Stop the pump by clicking the “Stop Pump” button. This will completely de-energize
the pump
3.
If there is a desire to have the pump not rotate but still have the impeller levitate, then enter “0” into “Pump
Rotation Speed” and this will permit the pump to stop rotating but the impeller will still be centered in the
pump housing.
The slowest speed besides 0 the pump can turn at is 100 RPMs. If a speed below that is selected the pump
will select a 0 RPM speed.
4.
For continued operation without the application running, the “serial lock” box must be checked. This will
effectually lock out PLC control.
