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.

7.6.15.4 - 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 disa-
bling 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 18.
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-en-
abling the system), the input must not be active for at least 1 sec. The
behaviour of the function is summed up in Table 17.
When several disable functions are configured at the same time on differ-
ent 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 18.
