Where the sign minus (-) become a square ( ) when the pump finish
the ramp-up step. The active step is indicated by a flashing
square ( ).
As the ten steps are fully covered, the pump will reach the Normal
operation. If during the Soft Start mode the current drawn by the
pump exceed 200 W the speed of the pump is decreased to maintain
the maximum power allowable (200 W).

where:
XX KRPM = indicates the actual theoretical rotational speed of the
pump as a function of the controller output frequency (range 3 to 42
KRPM).
After START command, frequency output will be at the maximum
level, then the frequency will decrease to a value proportional to the
pump rotational speed (about 4 KRPM of nominal frequency if the
pump is completely stopped).
The pump will accelerate to its normal rotational speed.
During acceleration of the pump or during any operating condition, it
is always possible to select the other parameters to be displayed
pressing the PUMP CURRENT or the CYCLE NUMBER pushbuttons.
After the run up time and when the normal rotational speed is
reached, the display will be as follows, even if any previous display
selection was made, and the normal condition has been reached.
