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 150 W the speed of the pump is decreased to
maintain the maximum power allowable (150 W).
If the Soft Start mode has been deselected the display will change
and shows:

where:
1 2 = contrast inverted identifies the set point condition:
1 is displayed when relay R1 is de-energized and the related
output is zero voltage.
2 is displayed when relay R2 is energized and the related
output is 24V.
XX KRPM = indicates the actual theoretical rotational speed of
the pump as a function of the controller output frequency (range
3 to 56 KRPM).
After START command, voltage and frequency output will be at
the maximum level, then the frequency will decrease to a value
proportional to the pump rotational speed (about 3 KRPM 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.
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.
