SMARTFLOW TUNE FUNCTION
A SMARTFLOW tune function will calibrate the necessary information to compensate for mechanical losses, volumet-
ric efficiency, casting defects, pump wear, eddy current losses, and general pump performance defects that can have an
effect on the total pump efficiency that will not show up on a standard performance curve.
Once the tune function is initiated the drive will start and ramp up the motor and stop briefly to gather information at
33%, 60% and 100% of the motor nameplate speed. It will automatically stop when it has completed.
To access the SmartFlow Tune function from the home screen, follow the path: Menu> PS220 Configuration> Smart-
flow>Tune Smartflow
NOTE: The tune function can be run at any time.
Prior to executing the Tune function:
1. All Suction and Discharge piping should be secure and ready for Pump startup.
2. Pump and motor aligned and coupled with coupling guard intact.
3. Suction line needs to be completely flooded and all air vented from the pump.
4. Discharge valve and any bypass piping needs to be completely closed.
5. For seal-less pumps having liquid lubricated bearings consult with the manufacturer and the customer to verify if the
pump can be run for 35 seconds against a closed discharge valve with the liquid that is to be pumped at the speeds noted
below.
General Notes:
Notes:
1. It is recommended to set 74.01 to keypad prior to running the tune. Once completed please set this parameter back to
the original setting.
2. Motor HP’s above 50 HP (37KW) will not run above 60% speed.
3. The tune function will automatically fault if it does not complete in 35 seconds.
4. Pumps with motors 15 HP or less should be run for 30 minutes prior to running the tune function.
5. Acceleration rates for PID Tuning should remain at default until after running the Smartflow Tune
6. If the tune function cannot be performed the algorithm will use the affinity laws. Selecting “No” automatically uses the
affinity laws in the calculations.
7. Do not run a SmartFlow Tune on any pump in a Multipump system. You will need to disable this on the PS220 connect-
ed to the pump to be Tuned and re-enable again when completed. Parameter 81.01 should be set to “DISABLED” if it
was set to SYNCHRONOUS using the PS220 Multipump Wizard previously.
8. Do not try to run a Smartflow Tune on a running pump.
9. Smart Control must be off prior to the tune function.
10. All information inputted with the wizard MUST be on water with SG of 1.0 and must be tuned with water like fluid
properties. If tuning on “Non-Water-Like” liquid several corrections will be needed. Please refer to the Tuning with Non
Water section in the index for the proper procedure.
