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 keys ↑↓ will 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 resto-
re 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, the pump will remain permanently out of order until the
damage will be repaired.
SOLUTION:
Dry running: 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 re-
acts 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 10).
A2 OVERCURRENT( Failure verification - Final failure)
DESCRIPTION: the pump is protected against over currents by mean of the intensity value 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 sys-
tem 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 configuration menu (see chapter 10) and configuring the adequated current value.
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 has
been solved the operation will be restored going to the configuration menu (see chapter 10) and introdu-
cing the adequate intensity value.
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 servi-
ce and as consequence the pump too.
SOLUTION: verify the temperature of the water, it should be under 40 ºC and the temperature environ-
ment 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 127-230 V.
