tions at a predetermined value.
7.4.3 - VP: Pressure display
Plant pressure measured in [bar] or [psi] depending on the measuring
system used.
7.4.4 - VF: Flow display
Displays the flow in the chosen unit of measure. The measuring unit may
be [l/min] o [gal/min] vedi par. 7.5.4 - MS: Measuring system.
7.4.5 - PO: Absorbed power display
Power absorbed by the electropump in [kW].
A flashing round symbol may appear under the symbol of the measured
power PO. This symbol indicates the pre-alarm for exceeding the allowed
maximum power.
7.4.6 - C1: Phase current display
Motor phase current in [A].
A flashing round symbol may appear under the symbol of the phase cur-
rent C1. This symbol indicates the pre-alarm for exceeding the allowed
maximum current. If it flashes at regular intervals it means that the motor
overload protection is about to trip and it will very probably go into protec-
tion status.
7.4.7 - RS: Rotation speed display
Motor rotation speed in rpm.
7.4.8 - TE: Dissipator temperature display
7.5 - Installer Menu
From the main menu, hold down simultaneously the "MODE" and "SET"
and "-" keys until the first parameter of the installer menu appears on the
display (or use the selection menu pressing + or -). The menu allows
you to view and modify various configuration parameters: the MODE key
allows you to scroll through the menu pages, the + and – keys allow you
respectively to increase and decrease the value of the parameter con-
cerned. Press SET to leave this menu and return to the main menu.
7.5.1 - RP: Setting the pressure fall to restart
Expresses the fall in pressure with respect to the SP value which causes
restarting of the pump.
For example if the setpoint pressure is 3.0 [bar] and RP è 0.5 [bar] the
pump will restart at 2.5 [bar].
RP can be set from a minimum of 0.1 to a maximum of 1 [bar]. In particu-
lar conditions (for example in the case of a setpoint lower than the RP) it
may be limited automatically.
To assist the user, on the RP setting page the actual restarting pressure
also appears highlighted under the RP symbol, see Figure 17.

7.5.2 - OD: Type of plant
VPossible values 1 and 2 referring to a rigid system and an elastic system.
The device leaves the factory with mode 1 suitable for the majority of
systems. In the presence of swings in pressure that cannot be stabilised
by adjusting the parameters GI and GP, change to mode 2.
IMPORTANT: The regulating parameters GP and GI also change in
the two configurations. In addition the GP and GI values set in mode
1 are stored in a different memory from the GP and GI values set in
mode 2. So, for example, when passing to mode 2, the GB value of
mode 1 is replaced by the GB value of mode 2 but it is kept and will
reappear again when returning to mode 1. The same value shown on
the display has a different weight in one mode or in the other because
the control algorithm is different.
7.5.3 - AD: Address configuration
This is significant only in a multi-pump connection. Set the communi-
cation address to be assigned to the device. The possible values are:
automatic (default) or manually assigned address.
