the input used. In this way, as well as SP, four other pressures are avail-
able, P1, P2, P3, P4.
When this function is active the symbol Pi is shown on the main page.
For the system to work with the auxiliary setpoint, the input must be ac-
tive for at least 1 sec.
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 17.
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
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 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-
enabling the system), the input must not be active for at least 1 sec. The
behaviour of the function is summed up in Table 18.
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 18.
