12. ALARMS .
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 pqwill be displayed the succesive alarms. Once visualized, for leaving the menu, press ENTER returning to
MANUAL mode.
A1 DRY RUNNING ( Failure verification Final failure)
DESCRIPTION: if the system detects dry running during more than 10 seconds, it will stop the pump and the ART (Automatic ResetTest) 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 device 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 (see paragraph 9).
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 configuration
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 operation will be
restored going to the "SET UP" menu (see the chapter configuration) and introducing the adequate intensity values. Verify the fuses (see
fig.3), in case of being melt contact with technical service.
A5 TRANSDUCER ( Final failure)
DESCRIPTION: the transducer damages are showed in the device LCD screen.
SYSTEM REACTION: the device operation is interrupted.
SOLUTION: contact with technical service.
A6 EXCESSIVE TEMP. Final failure
DESCRIPTION: the system has a cooling device 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 of the water, it should be under 40 ºC and 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 remains stopped for 10". Then it starts again - 4 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.
------
DESCRIPTION: blank screen.
SOLUTION: check the electric supply 230 V. In case of being in right conditions, the general fuse, located in the main plate (fig 1) should be
verified.
