13.3.1. Description of blockages
"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.
13.3.2. 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 5.6.10).
In Basic mode, once the condition of recurrence is detected the pump stops and awaits manual 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
the leak condition is detected, the parameter RP is increased to decrease the number of starts over time.
13.3.3. 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. However, this system has a protection that
prevents ice formation inside by activating the electropump when the temperature falls to values close to freezing point. In this way the
water inside is heated and freezing prevented.
The Anti-Freeze protection only works if the system is electrically powered: if the plug is disconnected or in the absence
of current the protection cannot work.
However, it is advised not to leave the system full during long periods of inactivity: drain the system properly through the
drainage cap and put it away in a sheltered place.
13.3.4. Anti-lock: Protection against pump long blocking
See paragraph AE: Enabling the anti-block function.
13.3.5. "BP1" "BP2" Blockage due to fault of the pressure sensors
If the device detects a fault in one of the two suction pressure sensor the pump remains blocked and the error signal "BP1"for delivery
pressure sensor and "BP2"
is detected and ends automatically once the sensor is replaced and correct conditions have been restored.
13.3.6. "PB" Blockage due to supply voltage outside specifications
This occurs when the allowed line voltage at the supply terminal assumes values outside the specifications. It is reset only automatically
when the voltage at the terminal returns within the allowed values.
13.3.7. "SC" Blockage due to short circuit between the motor phases
The device is provided with protection against the direct short circuit which may occur between the motor phases. When this blockage
is indicated you can attempt to restore operation by simultaneously holding down the
effect until 10 seconds have passed since the moment the short circuit occurred.
13.3.8. Manual reset of error conditions
In error status, the user can cancel the error by forcing a new attempt, pressing and then releasing the
