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.

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.
