6.6.13 Setup of auxiliary digital inputs IN1, IN2, IN3, IN4
This section shows the functions and possible configurations of the inputs by means of parameters I1, I2, I3,
I4.
For electrical connections, see section 2.2.4.
The inputs are all the same and all functions can be associated with each.
Each function associated with the inputs is explained in more detail further in this section.
Table 21 summarises the functions and various configurations.
The default settings are those in Table 20.

6.6.13.1 Disabling functions associated with input
If an input is configured at 0, each function associated with this input will be disabled, regardless of the signal
on the terminals of the input itself.
6.6.13.2 Setting the external float function
Activation of the external float function generates a system block. The function is envisaged to connect the
input to a signal from a float that indicates a water supply failure.
When this function is enabled, the symbol F1 is shown on the STATUS line of the main page.
The input must be activated for at least one second for the system to block and indicate the error F1.
