A1 INSUFFICIENT WATER (
DESCRIPTION: when the system detects insufficient water for more than 10 seconds, it will stop the pump and the ART system
(Automatic Reset) will be activated
SYSTEM RESPONSE: after 5 minutes the ART system will restart the pump for 30 seconds, seeking to restore the water supply to
the system. If the water shortage continues, the device will try again every 30 minutes for 24 hours. If after this period, the system
continues to detect insufficient water, the pump will be placed permanently out of service until the problem has been fixed.
SOLUTION:
• insufficient water, check the hydraulic circuit supply. If it is necessary to prime the pump, use the manual start button
START/STOP (check that the
• Request setting error: if a a "requested pressure" has been programmed that is greater than what the pump can provide, a
water insufficiency fault is triggered.
• Data set-up error: this device controls the insufficient water operation through the current consumption of the pump. Check
the current value introduced in the Configuration menu (see section "Configuration").

A2 OVERLOAD ( check fault,
DESCRIPTION: the system protects the pump against possible overloads, generally produced as a result of dysfunctions in the
pump or by the electric power supply.
SYSTEM RESPONSE: the device tries to start the pump again when there is a consumption request for up to 4 attempts, at the end
of which, if the system continues to detect the fault, the pump is permanently put out of service.
SOLUTION: verify the state of the pump, for example, that the rotor is not blocked, etc. Check that the current data introduced in
the Configuration menu is correct with the consumption of the pump. Also check the rotation direction for the three-phase pumps.
Once the problem is resolved, to restore operation of the pump enter the appropriate values in the "INSTALLATION" menu (see
