8.6.15.3 Setting auxiliary setpoint input function
The signal that enables an auxiliary setpoint can be supplied on any of the 4 inputs (for the electrical connections, refer to the control unit
manual). The auxiliary setpoint is obtained by setting the Ix parameter relating to the input on which the connection has been made, in
accordance with Table 14. Example: to use Paux 2 set I2 on 3 or 4 and use input 2 on the control unit; in this condition, if input 2 is energized,
pressure Paux 2 will be produced and the display will show P2. The auxiliary setpoint function modifies the system setpoint from pressure SP
(see par. 9.3 – Setpoint Menu) to pressure Pi, where is represents the input used. In this way, as well as SP, four other pressures are available,
P1, P2, P3, P4.
When this function is active the symbol Pi is shown in the STATUS line on the main page.
For the system to work with the auxiliary setpoint, the input must be active for at least 1sec.
When you are working with the auxiliary setpoint, to return to working with setpoint SP, the input must not be active for at least 1 sec. The
behaviour of the function is summed up in Table 14.
When several auxiliary setpoint functions are configured at the same time on different inputs, the system will show Pi when at least one function
is activated. For simultaneous activations, the pressure achieved will be the lowest of those with the active input. The alarm is removed when no
input is activated.

8.6.15.4 Setting system disabling and fault reset
The signal that enables the system can be supplied to any input (for the electrical connections refer to the control unit manual). The system
disabling function is obtained by setting the parameter Ix, relating to the input to which the signal to be used to disable the system is connected,
on one of the values shown in Table 15.
When the function is active, the system shuts down completely and the F3 symbol appears on the main page.
When several system disabling functions are configured at the same time on different inputs, the system will indicate F3 when at least one
function is activated and will remove the alarm when none is activated. For the system to work with the disable function, the input must be active
for at least 1 sec.
When the system is disabled, for the function to be deactivated (re-enabling the system), the input must not be active for at least 1 sec. The
behaviour of the function is summed up in Table 15.
When several disable functions are configured at the same time on different inputs, the system will show F3 when at least one function is
activated. The alarm is removed when no input is activated.
This function also allows the resetting of any faults present, see Table 15.
