7.7.8.3 - Setting auxiliary setpoint input function
The signal that enables an auxiliary setpoint may be supplied on any one
of the 4 inputs, (for the electrical connections see paragraph Input con-
nections (photocoupled).
The auxiliary setpoint function is obtained, setting the parameter Ix, for
the input to which the connection has been made, according to Table 14.

nections see paragraph connections (photocoupled) where is represents
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 STATUS line
of 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 14.

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.

When this function is active the symbol F1 is shown on the STATUS line
of the main page.
For the system to block and give the error signal F1, the input must be
activated for at least 1 sec.
When it is in error condition F1, the input must have been deactivated for
at least 30 sec before the system can be unblocked. The behaviour of
the function is summed up in Table 13.

and will remove the alarm when none is activated.
