6.6.13.5 Setting low pressure detection
Activation of the low pressure detection function generate a system block after time T1 (see T1: Tempo di
spegnimento dopo il segnale bassa pressione par. 6.6.2). This function is envisaged to connect the input to
a signal from a pressure switch that indicates excessively low pressure on pump intake.
When this function is enabled, the symbol F4 is shown on the STATUS line of the main page.
When in the F4 error condition, the input must be deactivated for at least 2 seconds before the system
unblocks. The function behaviour is summarised in Table 25.
When several low pressure detection functions are configured at the same time on different inputs, the
system indicates F4 when at least one function is activated and clears the alarm when none are activated.

6.6.14 Setup of outputs OUT1, OUT2
This section illustrates the functions and possible configurations of the outputs OUT1 and OUT2 via
parameters O1 and O2.
For electrical connections, see section 2.2.4.
The default settings are those in Table 26.
Default output settings
Output Value
OUT 1 2 (fault NO closes)
OUT 2 2 (Pump running NO closes)
