6.6.13.3 Setting the auxiliary pressure input function
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).
The signal that enables an auxiliary set point can be supplied on any one of the 4 inputs, (for electrical connections, refer to paragraph
2.2.4.2). The auxiliary set point function is obtained by setting parameter INx, associated with the input on which the connection is
made, in accordance with Table 24.
The auxiliary pressure function modifies the system setpoint from pressure SP (see section 6.3) to pressure Pi . For electrical
connections, see paragraph 2.2.4.2) where i represents the input used. In this way, as well as SP there are four additional pressures
available: P1, P2, P3, and P4.
When this function is enabled, the symbol Pi is shown on the STATUS line of the main page.
The input must be active for at least 1 second for the system to operate with the auxiliary setpoint.
When operating with the auxiliary setpoint, the input must not be active for at least 1 second to return to operation with setpoint SP.
The function behaviour is summarised in Table 24.
If several auxiliary pressure values are configured at the same time on different inputs, the system indicates Pi when at least one
function is activated. For simultaneous activations, the pressure reached will be the lowest from those with the input active. The alarm
is cleared when no input is activated.

6.6.13.4 Setting the system enable and fault reset
The signal that enables the system can be supplied from any input (for electrical connections, refer to paragraph 2.2.4.2) The system
enable function is obtained by setting the parameter INx, associated with the input where the enable signal is connected, to one of the
values in Table 24.
When this function is active, the system is totally disabled, and F3 is displayed n the STATUS line of the main page.
When several system disable functions are configured at the same time on different inputs, the system indicates F3 when at least one
function is activated and clears the alarm when none are activated.
The input must be active for at least 1 second for the system to implement the disable function.
When the system is disabled, the input must not be active for at least 1 second for the function to be deactivated (system re-enable).
The function behaviour is summarised in Table 25.
If several disable functions are configured at the same time on different inputs, the system indicates F3 when at least one function is
activated. The alarm is cleared when no input is activated.
