6.1 - 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 5.6.10).
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. 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 works only if the system is regularly fed: with the plug 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 accurately through the drainage cap and put
it away in a sheltered place.
6.1.4 - "BP1" Blockage due to fault of the delivery pressure sensor (system pressurisation)
If the device detects a fault in the delivery pressure sensor the pump remains blocked and the error signal "BP1" is given. This status begins as
soon as the problem is detected and ends automatically when correct conditions have been restored.
6.1.5 - "BP2" Blockage due to fault of the suction pressure sensor
If the device detects a fault in the suction pressure sensor the pump remains blocked and the error signal "BP2" is given. This status begins as
soon as the problem is detected and ends automatically when correct conditions have been restored.
6.1.6 - "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.
6.1.7 - "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 ˄ and ˅ keys, but this will not have any effect until 10 seconds have
passed since the moment the short circuit occurred.
6.2 - Manual reset of error conditions
In error status, the user can cancel the error by forcing a new attempt, pressing and then releasing the ˄ and ˅ keys.
6.3 - Self-reset of error conditions
For some malfunctions and blockage conditions, the system attempts automatic self-reset.
The auto self-reset procedure concerns in particular:
"BL"
Blockage due to water lack
"PB"
Blockage due to line voltage outside specifications
"OT"
Blockage due to overheating of the power stages
