Note:
For independent sensorless operation, go to Section 1.
For independent external sensor operation, go to Section 2.
For external controller, go to Section 3.
1. Open up and bleed pump seal flush line to verify no air has travelled into seal / seal lines
2. Change parameter 0-20 (default value is option 1601 – “Reference [Unit]”) to option 1850 “Sensorless
Readout” to display Sensorless flow readout on the top left corner of screen
3. Change parameter 0-22 (default value is option 1610 – “Power [kW]”) to option 1654 “Feedback 1
[Unit]” to display Sensorless pressure readout on the top right corner of screen
4. Open the discharge valve and set the pump to the design duty speed and record the VFD Sensorless
pressure and flow readout (include units). This is what the actual system flow and head are.
SENSORLESS PRESSURE =
SENSORLESS FLOW =
5. Ramp the pump up or down to achieve the design flow. Record the VFD sensorless flow and pressure
–this will be your new setpoint.
SENSORLESS PRESSURE =
SENSORLESS FLOW =
6. Set parameter 20-21 to the Sensorless Pressure readout taken in previous step
7. Set parameter 22-89 to the Sensorless Flow readout taken in previous step
8. Set parameter 22-87 to a value that is 40% of the value in 20-21. You have now readjusted the
quadratic control curve to match actual site conditions.
9. Change parameter 0-20 back to the default value of option 1601 – “Reference [Unit]”
10. Change parameter 0-22 back to the default value of option 1610 – “Power [kW]”
11. Put the VFD into AUTO mode. The pump will ramp up to get to the setpoint pressure and as the
demand in the system decreases, the setpoint will also decrease to ride the control curve down to the
minimum pressure set in parameter 22-87. As demand increases, it will ride back up the control curve to
full design setpoint.
Note:
Sensor signal wire must be connected to analog input terminal 54
1. Open up and bleed pump seal flush line to verify no air has travelled into seal / seal lines
2a. If your sensor provides a voltage (V) signal, go to step 3.
2b. If your sensor provides a milliamp (mA) signal, make sure switch S202 for A54 (located behind the
keypad) is pushed to the ON position (to the right) and go to step 5.
3. Change parameter 6-20 to match the low end of voltage signal from the sensor (eg: if your sensor
provides a 0-10V signal, enter 0). Go to step 4.

4. Change parameter 6-21 to match the high end of voltage signal from the sensor (eg: if your sensor
provides a 0-10V signal, enter 10). Go to step 7.
5. Change parameter 6-22 to match the high end of current signal from the sensor (eg: if your sens or
provides a 4-20mA signal, enter 4). Go to step 6.
