7.4 Connection of the alarm outputs

If alarms occur, this is indicated by the E.box in three ways:

With the leds on the front panel, which give a number of blinks depending on the error.

With the outputs Q1, Q2, Q3 which short circuit as specified in Table 17. The operating logic of the alarms is
as follows: Q1 closes following malfunctions of pump 1, Q2 of pump 2 and Q3 for general errors.

With the indications on the display (if present). In this case it is also possible to see the alarm log.
If the panel is not fed, Q1, Q2 and Q3 are closed, so they give an alarm signal.

7.5 Connection of floats or level probes

2 or 3 control inputs can be used which must be connected as follows:

System with 2 floats or level probes: in this case inputs B and C are used. Terminal A must be left free. The
floats in the tank must be connected as in Figure 31. For electrical installation, see Figure 34 Inputs.

System with 3 floats or level probes: in this case inputs A, B and C are used. The floats in the tank must be
connected as in Figure 31: drainage system diagram. For electrical installation, see Figure 34 Inputs.
Common contact of the inputs. There is only one common contact for all the inputs and it is connected
to the even terminals from 2 to 10. So, if level probes or electric probes are used, the common contact for
the inputs A, B, C, R, N must be connected to the terminals with even numbers: 2, 4, 6, 8, 10.
Level probes: use them only with clear, clean water.

7.6 Depth sensor connection

The E.Box may use a depth sensor as a control device. If an E.box with a display is used, the too high or too low level
alarms can be read by the depth sensor. So it is not necessary to connect floats or level probes to the inputs R or N.
If maximum reliability is desired, as well as the depth sensor 2 floats or level probes can also be used, for the alarms
R and N.
The depth sensor must be positioned near the bottom of the tank, ensuring that it is above any solid residue or
impurities, present or future.
