RF: Fault and warning reset

Holding down the + and – keys together for at least 2 seconds deletes the history of faults and warnings. The number of
faults present in the log is indicated under the symbol RF (max 64).
The log can be viewed from the MONITOR menu on page FF

6. PROTECTION SYSTEMS

The device is equipped with protection systems to preserve the pump, the motor, the supply line and the inverter. If one
or more protections trip, the one with the highest priority is immediately notified on the display. Depending on the type of
error the motor may stop, but when normal conditions are restored the error status may be cancelled immediately or only
after a certain time, following an automatic reset.
In the case of blockage due to water lack (BL), blockage due to motor overload (OC), blockage due to direct short circuit
between the motor phases (SC), you can try to exit the error conditions manually by simultaneously pressing and
releasing the + and – keys. If the error condition remains, you must take steps to eliminate the cause of the fault.
In the event of blocking due to one of the internal errors E18, E19, E20, E21 it is necessary to wait 15 minutes with the
machine powered until the blocked status is automatically reset.

Description of blockages

6.1.1 "BL" Anti Dry-Run (Protection against dry running)

In the case of lack of water the pump is stopped automatically after the time TB. This is indicated by the red "Alarm" led
and by the letters "BL" on the display. After having restored the correct flow of water you can try to leave the protective
block manually by pressing the "+" and "-" keys simultaneously and then releasing them. If the alarm status remains, or if
the user does not intervene by restoring the flow of water and resetting the pump, the automatic restart will try to restart
the pump.
If the parameter SP is not correctly set, the protection against water lack may not work correctly.

6.1.2 Anti-Cycling (Protection against continuous cycles without utility request))

If there are leaks in the delivery section of the plant, the system starts and stops cyclically even if no water is intentionally
being drawn: even just a slight leak (a few ml) can cause a fall in pressure which in turn starts the electropump.
The electronic control of the system is able to detect the presence of the leak, based on its recurrence.
The Anti-Cycling function can be excluded or activated in Basic or Smart mode (par 5.6.6).
In Basic mode, once the condition of recurrence is detected the pump stops and remains waiting to be manually reset.
This condition is communicated to the user by the lighting of the red "Alarm" led and the appearance of the word
"ANTICYCLING" on the display. After the leak has been removed, you can manually force restart by simultaneously
pressing and releasing the "+" and "-" keys.
In Smart mode, once the leak condition is detected, the parameter RP is increased to decrease the number of starts over
time.

6.1.3 Anti-Freeze (Protection against freezing of water in the system)

The change of state of water from liquid to solid involves an increase in volume. It is therefore essential to ensure that
the system does not remain full of water with temperatures close to freezing point, to avoid breakages of the system.
This is the reason why it is recommended to empty any electropump that is going to remain unused during the winter.
