1 2 = contrast inverted identifies the set point condition:
XX KRPM = indicates the actual theoretical rotational speed of the
pump as a function of the controller output frequency (range 3 to 56
KRPM).

Where the sign minus (-) become a square ( ž ) when the pump
finish the ramp-up step. The active step is indicated by a flashing
square (€ ž ).
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 1.7 A the speed of the pump is
decreased to maintain the maximum power allowable (1.7 A).
If the Soft Start mode has been deselected the display will change
and shows:

1 is displayed when relay R1 is de-energized
2 is displayed when relay R2 is energized.
After pump start-up, voltage and frequency output will be at the
maximum level, then the frequency will decrease to a value
proportional to the pump rotational speed (3 KRPM if the pump
is completely stopped). The pump will accelerate to its normal
rotational speed.
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.
