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 values 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 system 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).
Figure 16: Power histogram display
5.1.13 - Output flow meter
The page shows two flow meters. The first shows the total output flow delivered by the
machine. The second shows a partial count and can be reset by the user. The partial count
can be reset from this page, by holding down the " ˅ " button for 2 sec.
5.1.14 - VE: Version display
Hardware and software version with which the appliance is equipped.
Hardware and software 2.7.0 and later, the following also applies:
on this page after the prefix S: the last 5 figures of the single serial number
attributed for connectivity are showed. The whole serial number can be viewed by pressing
the "˄" key."
