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 1.4 A the speed of the pump is
decreased to maintain the maximum power allowable (1.4 A).
If within each step of the Soft Start mode the rotational speed of
the pump do not rech the planned value within 15 minutes the
display shows:

where X = the step number from 0 to 9 indicating the step
number not passed.
When this message is displayed the pump is stopped.
Reset the controller by pressing twice the STOP push-button to
start the pump.
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.
XX KRPM = indicates the actual theoretical rotational speed of
the pump as a function of the controller output frequency (range
9 to 75 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 9 KRPM if the pump is
completely stopped).
