13. 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 ( ) 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 res-
tore 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: 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 1: If the pump cannot provide the programmed pressure (configuration mistake) the unit 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.
A2 OVER-LOAD PUMP 1 - A3 OVER-LOAD PUMP 2 ( ) 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 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 resto-
red going to the "SET UP" menu ( see the chapter configuration) and configuring the adequated intensity
values.
A4 LEVEL ( ) Verification failure
DESCRIPTION: The device has an external input that if it si configurated as "LEVEL", will activate this alarm.
SYSTEM RESPONSE: The functioning of the system is interrupted until the state of the level.
SOLUTION: Check conections and/or configuration of the external input as function "LEVEL".
A5 TRANSDUCER ( ) Final failure
DESCRIPTION: The transducer damages are showed in the LCD screen.
SYSTEM REACTION: The device operation is interrupted.
SOLUTION: Check the external pressure transmitter.
A6 EXCESSIVE TEMP. PUMP 1 - A7 EXCESSIVE TEMP. PUMP 2 ( ) 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 environment should be under 50 ºC. Also verify the mechanical installa-
tion chapter. Contact with technical service.
