6.6.13.5 Setting low pressure detection (KIWA)
The minimum pressure switch that detects low pressure can be connected to any input (for electrical connections, refer to paragraph
2.2.4.2) The low pressure detection function is obtained by setting the parameter INx, associated with the input where the enable
signal is connected, to one of the values in Table 26.
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 26.
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 27.
