Procedure
To stop flow, close the main valve.
Run with motor until the system has reached normal operating temperature.
Press the [Hand On] key on the LCP and adjust speed for approximately 85% of the rated speed. Note the exact speed.
Read power consumption either by looking for actual power in the data line in the LCP or call parameter 16-10 Power [kW] in
the Main Menu. Note the power readout.
Change speed to approximately 50% of the rated speed. Note the exact speed.
Read power consumption either by looking for actual power in the data line in the LCP or call parameter 16-10 Power [kW] in
the Main Menu. Note the power readout.
Program the speeds used in parameter 22-33 Low Speed [Hz] and parameter 22-37 High Speed [Hz].
Program the associated power values in parameter 22-34 Low Speed Power [kW] and parameter 22-38 High Speed Power [kW].
Switch back pressing [Auto On] or [Off].
