ALARMS FOR SINGLE ASSEMBLY.
In case of simultaneous alarms, quit the automatic mode and go to manual mode, pressing the pushbutton
AUTOMATIC ON/OFF (led light PUMP will turn off). Using key ▲ ▼ will be displayed the succesive alarms. Once
visualized, for leaving the menu, press ENTER returning to MANUAL mode.
A1 DRY RUNNING (☼ Failure verification - 
DESCRIPTION: if the system detects dry running during more than 10 seconds, it will stop the pump and the ART (Automatic Reset
Test) will be activated.
SYSTEM REACTION: after 5 minutes ART system will start again the pump during 30 seconds, trying to restore the system. In case of
persistent lack of water, it will try it again every 30 minutes for 24 hours. If after all these cycles , the system still detects lack of water,
pump will remain permanently out of order until the damage will be repaired.
SOLUTION: dry running, it has been activated the safety system: you should verify the feeding of the hydraulic network. The pumps
can be primed using the push-button START/STOP ( the led light AUTOMATIC should be off, if it is not, press the push-button to
disable it).
Special case: if the pump cannot provide the programmed pressure (configuration mistake) the unit reacts as it was dry-running.
Special Case 2: this device manages the dry running control through the nominal current consumption of the pump. It must be
verified the introduced current consumption in the setup menu.
A2 OVER-INTENSITY (☼ Failure verification -  Final failure)
DESCRIPTION: the pump is protected against over currents by mean of the intensity values established in the installation menu.
These over currents are produced generally by dysfunctions in the pump or in the electric supply.
SYSTEM REACTION: when detecting the thermal failure, the pump will be automatically stopped. The system will try again to restart
the pump when the demand of consumption require it. The control system will carry out 4 attempts in this circumstances. If the
system remain locked after the 4th attempt, the pump will remain definitively out of order.
SOLUTION: verify the state of the pump, for example the impeller could be blocked. Verify intensity values introduced in the confi-
guration menu. Once the problem have been solved the operation will be restored going to the "SET UP" menu ( see the chapter
configuration) and configuring the adequated intensity values.
A3 DISCONNECTED P. ( Final failure)
DESCRIPTION: the device has an electronic safety system in case of no load detection.
SYSTEM REACTION: the device is disconnected..
SOLUTION: the wound of the motor and the pump consumption should be verified. Once the problem have been solved the ope-
ration will be restored going to the "SET UP" menu (see the chapter configuration) and introducing the adequate intensity values.
A5 TRANSDUCER ( Final failure)
DESCRIPTION: the transducer damages are showed in the device LCD screen.
SYSTEM REACTION: the device operation is interrupted.
SOLUTION: check the external pressure transmitter.
A6 EXCESSIVE TEMP ( Final failure)
DESCRIPTION: the system is cooled by the motor fan to keep the INVERTER in optimum working conditions.
SYSTEM REACTION: if an excessive temperature is reached the own system leaves the inverter out of service and as consequence
the pump too.
SOLUTION: verify the temperature environment should be under 50 ºC. Contact with technical service.
A7 SHORTCIRCUIT ( Final failure)
DESCRIPTION: the device has an electronic system for protection against short circuits as well as peaks of current.
SYSTEM REACTION: the pump stops and then it starts again -performing 4 successive attempts. If the problem is not solved, the
pump will remain definitively out of order.
SOLUTION: check the pump, if the problem persists, contact the technical service.
A8 OVERVOLTAGE - A9 UNDERVOLTAGE (☼ Failure verification)
DESCRIPTION: the device has an electronic safety system against overvoltages and too low supply voltages.
SYSTEM REACTION: in case of overvoltage or undervoltage the system remains stopped until an adequate value of voltage is
reached. In this case, the system is automatically restored.
SOLUTION: check the electric supply.
ALARM INSTALLATION MASTER-SLAVE

A10 COMUNICA ( Failure verification)
DESCRIPTION: If you have configured a Master-Slave system and communication cable is disconnected or there is a bad connec-
tion, the system stops.
SYSTEM REACTION: The Master-Slave system stops and starts to operate individually.
SOLUTION: Check the cable connection and if this is OK, check the connection inside the unit. Check the configuration of the
Master-Slave system (setup menu).
--------
DESCRIPTION: blank screen.
SOLUTION: check the electric supply 230 V.
