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 R 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 contacts of the terminal R are left open.
If the depth sensor is used to obtain this alarm, the parameter ML must be set at the highest level that the liquid can
safely reach.
Note: if this alarm is active, the pumps start automatically.

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 contact N of the E.box and
positioned in the tank in the lowest point that the liquid can safely reach.
Note: in case of an alarm, the pumps stop.
If the depth sensor is used to obtain this alarm (only for E.Box with display), the parameter LL must be set at the
lowest level that the liquid can safely reach.
Note: if this alarm is not used, input N must be jumpered. To identify input N, refer to Figure 32.
Motor thermal protection: the E.box 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. For the position of the terminals, see Figure 33.
