If the depth sensor is used to obtain this alarm (only for Ebox with display), the threshold ML must be set at the highest level
that the liquid can safely reach.
Minimum level alarm: the signal for this alarm may come from a float, from a level probe, or from the depth sensor (only for
•
Ebox with display). The level probe or float must be connected to terminal N of the Ebox and positioned in the tank in the
highest point that the liquid can safely reach. If the depth sensor is used to obtain this alarm, the threshold LL must be set
at the lowest level that the liquid can safely reach.
Note: if this alarm is active, the pumps start automatically.
Note: if this alarm is not used, and the protection devices are level probes, the input R must be jumpered.
Not in other cases.
Motor thermal protection: the device has an input for the thermal protection of each motor. If the motor used is provided
•
with thermal protection, this protection can be connected to the terminals KK. If the protection is not present in the motor,
the terminals must be jumpered. The terminals can be seen in Figure 21.

Connection of the alarm outputs
If alarms occur, this is indicated by the Ebox 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.
6.5
Connection of floats or level probes
2 or 3 control inputs can be used which must be connected as follows:
System with 2 floats: in this case inputs B and C are used (A must not be used). The floats in the tank must be positioned
•
as in Figure 19. For electrical installation, see Figure 22.
System with 2 level probes: in this case inputs B and C are used (A must not be jumpered). The level probes in the tank
•
must be positioned as in Figure 19. For electrical installation, see Figure 22.
System with 3 floats or level probes: in this case inputs A, B and C are used. The floats or level probes must be positioned
•
as in Figure 19. For electrical installation, see Figure 22.
