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.

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.
