2.3 SmartFlow Tune Wizard
Please refer to the Features & Functions section in this manual for a detailed
explanation of this functionality. This Wizard will show the step-by-step in-
structions to configure this functionality for use.
To access this Wizard, from the Home Screen follow the path: Menu>PS220
Configuration>Smartflow> Tune Smartflow
The Screen Shots that follow will show you step by step as you progress, from
start to finish, how to configure this functionality.
2. Execute the Smartflow Tune
The Tune Function requires the pump to be run on its own using a predefined
algorithm.
Once the tune function is initiated the drive will start and ramp up the motor
and stop briefly to at 33%, 60% and 100% of the motor nameplate speed. It
will automatically stop when it has completed.
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 run-
ning 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 connected to the pump to be tuned and
re-enable again when completed. Parameter 81.01 should be set to “DIS-
ABLED” 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-Wa-
ter-Like” liquid several corrections will be needed. Please refer to the Tuning
with Non Water section in the index for the proper procedure.
