6.3 Setpoint menu
From the main menu, press and hold MODE and SET simultaneously until “SP” appears on display (or use the b or – in the
selection menu).
B 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.
Regulation pressure values
Type of sensor used Regulation pressure [bar] Regulation pressure [psi]
16 bar 1,0 - 15,2 14 - 220
25 bar 1,0 - 23,7 14 - 344
40 bar 1,0 - 38,0 14 - 551
Table 16: Maximum regulation pressure values
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:
