5 - MEANING OF THE INDIVIDUAL PARAMETERS

The inverter makes the system work at constant pressure. This
regulation is appreciated if the hydraulic plant downstream from
the system is suitably sized. Plants made with pipes with too
small a section introduce load losses that the equipment cannot
compensate; the result is that the pressure is constant on the
sensors but not on the utility.
Plants that are excessively deformable can create the onset
of oscillations; if this occurs, the problem can be solved by
adjusting the control parameters "GP" and "GI" (see par 5.6.3
- GP: Proportional gain coefficient and 5.6.4 - GI: Integral gain
coefficient)

5.1 - User Menu

From the main menu, pressing the MODE key (or using the selection menu
and pressing + o - ), gives access to the USER MENU. In the menu the
MODE key allows you to scroll through the various menu pages. The val-
ues shown are the following.

5.1.1 - Status:

Displays the pump status.

5.1.2 - RS: Rotation speed display

Motor rotation speed in rpm..

5.1.3 - VP: Pressure display

Plant pressure measured in [bar] or [psi] depending on the measuring sys-
tem used.

5.1.4 - VF: Flow display

Displays the instantaneous flow in [litres/min] or [gal/min] depending on the
set measuring system.

5.1.5 - PO: Absorbed power display

Power absorbed by the electropump in [kW].
If the maximum allowed power is exceeded, the identification PO blinks.

5.1.6 - C1: Phase current display

Motor phase current in [A].
If the maximum allowed current is exceeded, the identification C1 blinks,
indicating an imminent tripping of the overload protection.

5.1.7 - SV: Supply voltage

Present only in some models.

5.1.8 - SR: Supply range

Present only in some models.
Indicates the range of supply voltage found. It may have the values: [110-
127] V or [220-240] V. If the range is not determined, it has the value "- -".

5.1.9 - TE: Dissipator temperature display

5.1.10- PKm: Pressure measured at suction

Present only in models with Kiwa function

5.1.11 - Operating hours and number of starts

Indicates on three lines the hours that the device has been powered up,
the pump working hours and the number of starts of the motor.

5.1.12 - PI: Power histogram

A histogram of the power delivered is displayed on 5 vertical bars. The
histogram indicates how long the pump has been on at a given power
level. On the horizontal axis are the bars at the various power levels; on
the vertical axis, the time for which the pump has been on at the specific
power level (% of the time with respect to the total).
