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.
