XX
=indicates the rotational speed
(75 KRPM for high speed, or 50 KRPM for low
speed).
During acceleration of the pump or during any
operating condition, it is always possible to select
the other parameters to be displayed (PUMP
CURRENT or CYCLE NUMBER push-buttons).
If this is the case when the pump reaches the
normal speed, the display reverts to the previous
figure.

where:
•
I
= is the DC current drawn by the pump range (0.00
to 9.99 Ampere)
•
P
= is the DC power drawn by the pump (range 0 to
999 Watt)
•
KRPM
= is the theoretical rotational speed of the
pump as a function of the controller output
frequency (range 9 to 75 KRPM)
•
°C
= is the temperature of the outer ring of the
upper bearing (range 00 to 99 °C)
•
X
= during operation a selected set point condition

PROGRAM MODE
FRONT / REMOTE/ 232 Selection
•
Press CYCLE NUMBER and PUMP CURRENT
push-buttons together for at least 2 seconds and
the processor enters in a routine where it is
possible to program the controller.
In this routine, the CYCLE push-button is used for
choosing/changing the value or condition; the
PUMP CURRENT push-button is used to enter and
confirm the value. At any time it is possible to exit
this routine by pressing the CYCLE and PUMP
CURRENT push-buttons at the same time for at
least 2 seconds.

where:
XXX
= YES or NO.
If YES is selected, the Soft Start mode allows the pump
to ramp-up the Normal speed within ten steps.
When NO is selected, the Soft Start mode is
deselected and the ramp-up of the pump will be done
within 75 seconds.
The controller is factory set to YES.
