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. Depend- ing 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 event of a blockage due to an error, you can attempt to exit the error conditions manually by sending the appropriate command.
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
8.1.1
"BL" Anti Dry-Run (Protection against dry running)
In the case of dry running the pump is stopped automatically after the time TB.
After having restored the correct flow of water you can try to leave the protective block manually by sending the Error Reset
command. 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 dry running may not work correctly.
8.1.2
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.
Indication
Cutout due to pump overheating
PH
Blockage due to dry operation
BL
Blockage due to reading error on the delivery pressure sensor
BP1
Blockage due to supply voltage outside specifications
PB
OT
Blockage due to overheating of the power stages
OC
Blockage due to motor overload
NC
Blockage due to motor disconnected
Ei
Blockage due to i-th internal error
Vi
Blockage due to i-th internal voltage out of tolerance
EY
Block for cyclicality abnormal detected on the system
