14. 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 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 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-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 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.
A4 LEVEL( Verification failure)
DESCRIPTION: the device has a extern exit 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 extern exit 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 Final failure
DESCRIPTION: the system has a cooling device to keep the INVERTER in optimum working conditions. It also has the automatic STC function
to react to overheating of the electronics (see 3. Main Characteristics).
SYSTEM REACTION: if the maximum safety temperature is exceeded, the system leaves the inverter out of service and as consequence the
pump too.
SOLUTION: Verfy current draw by the pump. Verify the temperature environment should be under 50 ºC. Contact with 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.
A12 MAX PRES ( ) Final failure
DESCRIPCIÓN: the device has an electronic system to protect maximum pressures.
RESPONSE OF THE SYSTEM: If the device detects a higher pressure than the configurated as "P.MAX" during a longer time than the
configurated as "t P.MAX" it will happen a final failure stopping the system.
SOLUTION: Check consign pressure and maximum pressure.
A13 P. MIN ( ) Final failure
DESCRIPTION: the device has a protection system for low pressures.
SYSTEM RESPONSE: If the device detects a pressure lower than the configurated as "P.MIN" during a longer time thas the configurated as "t
P.Min" it will appear a final failure stopping the system.
SOLUTION: Check for leakages on the instalation and the value of the minimum pressure configurated.
A14 SHORTCIRCUIT PUMP 1 - A15 SHORTCIRCUIT PUMP 2( 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.
A16 PUMP 1 OFF - A17 PUMP 2 OFF ( ) F inal failure
DESCRIPTION: the device has a protection system for the failure of the power electronic circuit or desconection of the pump.
SYSTEM RESPONSE: If the devie doesn't detect consumption of the electropump, this will be turned off and the system will work only with the
other pump and its inverter. On the menu will appear NOM CURRENT P1 OFF (A16) NOM CURRENT P2 OFF (A17).
SOLUTION: Check the pump connections or contact with the tecnic service.
