As the ten steps are fully covered, the pump will reach the Normal
operation. If during the Soft Start mode the power drawn by the
pump exceed 200 W the speed of the pump is decreased to maintain
the maximum power allowable (200 W).

where:
1 2 = contrast inverted identifies the set point condition:
XX Hz = indicates the actual theoretical rotational speed of the pump
as a function of the controller output frequency.
HJ = displayed only when the heater jacket is active.
HS/HL = indicates that the pump is working in the High speed or
Low speed mode.
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 3 Hz if the pump is completely
stopped).
The pump will accelerate to its normal rotational speed.

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.
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.
