The auxiliary setpoint function is obtained by setting the parameter Ix, for the input to which the auxiliary setpoint
signal has been connected, on one of the values in Table 25.
The auxiliary pressure function modifies the system setpoint from pressure SP (see section 6.3) to pressure Pi . For
electrical connections, see paragraph 2.3.3 where i represents the input used.
In this way, as well as SP, the pressures P1, P2, P3 are available.
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.

6.6.15.4 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
2.3.3).
The system enabling function is obtained by setting the parameter Ix, for the input to which the system enabling
signal has been connected, on one of the values in Table 25.
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.
