Setpoint menu

From the main menu, press and hold MODE and SET simultaneously until "SP" appears on display (or use the buttons + or – in the
selection menu).
Buttons + and – enable respectively to increase and decrease the system pressurisation value.
To exit the current menu and return to the main menu, press SET.
This menu enables the user to set the system operating pressure.
The pressure range depends on the sensor used (see PR: Pressure sensor section 6.5.7) and varies as shown in Table 16. System
pressure can be displayed in [bar] or [psi] depending on measurement system used.
Type of sensor used
16 bar
25 bar
40 bar
6.3.1

SP: Setting the setpoint pressure

Pressure to apply to the system if the auxiliary pressure regulation functions are not active.
6.3.2

Auxiliary pressure settings

The inverter can vary the set point pressure according to the status of the inputs; up to 4 auxiliary pressure values can be set for a
total of 5 different set points. For the electrical connections, refer to paragraph 2.2.4.2, and for software settings, refer to paragraph
6.6.13.3.
If there are several auxiliary pressure functions active, associated with several inputs, the inverter applies the lowest
pressure of all those activated.
The auxiliary set points are disabled if the flow sensor is not used (FI=0) and when FZ is used in minimum frequency
mode (FZ ≠ 0).
6.3.2.1

P1: Auxiliary pressure 1 setting

Pressure to apply to the system if the auxiliary pressure function is activated on input 1.
6.3.2.2

P2: Auxiliary pressure 2 setting

Pressure to apply to the system if the auxiliary pressure function is activated on input 2.
6.3.2.3

P3: Auxiliary pressure 3 setting

Pressure to apply to the system if the auxiliary pressure function is activated on input 3.
6.3.2.4

P4: Auxiliary pressure 4 setting

Pressure to apply to the system if the auxiliary pressure function is activated on input 4.
The pump restart pressure depends both on the set pressure (SP, P1, P2, P3, P4) and RP.
RP expresses the reduction in pressure, with respect to "SP" (or an auxiliary pressure if activated), which generates
pump start-up
Example: SP = 3,0 [bar]; RP = 0,5 [bar]; no auxiliary pressure function active:
