If the display is present, in all cases the type of alarm is indicated.
When the alarm conditions no longer exist, the E.box resumes normal operation.

Maximum level alarm: the signal for this alarm may come from a float, from a level probe, or from the depth
sensor (only for E.Box with display). The level probe or float must be connected to terminal N of the E.box and
positioned in the tank in the highest point that the liquid can safely reach.
Note: if this alarm is not used, the terminal N must be jumpered except in the case where level probes are
used.
If the depth sensor is used to obtain this alarm (only for E.Box 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 E.Box with display). The level probe or float must be connected to terminal N of the E.box
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.
