A3 PUMP OFF ( DEFINITIVE FAULT):
DESCRIPTION: The device has an electronic protection system against short circuits and a fuse.
SYSTEM RESPONSE: operation of the device is stopped.
SOLUTION: check the winding of the motor and also the pump consumption. Once the pump problem has been resolved, to restore
its operation introduce the appropriate current value in the "INSTALLATION" menu (see Configuration). Check the fuse. If it has blown,
contact technical support (see Fig. 1).
•
A5 DAMAGED TRANSDUCER ( DEFINITIVE FAULT):
DESCRIPTION: The device signals a fault on the pressure sensor.
SYSTEM RESPONSE: operation of the device is stopped.
SOLUTION: Check the fuse. If it has blown, contact technical support (see Fig. 1).
•
A6 EXCESSIVE TEMPERATURE ( DEFINITIVE FAULT):
DESCRIPTION: the device has a cooling system to keep the inverter in excellent working condition.
SYSTEM RESPONSE: If for any reason the device reaches an excessive temperature, the system puts the inverter and therefore the
pump out of service.
SOLUTION: Verify that the water temperature does not exceed 40ºC, and that the ambient temperature does not exceed 50ºC. Contact
technical support
•
A7 SHORT CIRCUIT ( DEFINITIVE FAULT):
DESCRIPTION: the device has an electronic protection system against short circuit and a fuse.
RESPONSE: the pump stops for 10s. Then it is put back into operation for a maximum of 4 attempts. If the problem is not resolved, a
definitive fault is produced.
SOLUTION: check the pump; if the problem continues contact the manufacturer.
A8 OVERVOLTAGE ( * CHECK FAULT):
DESCRIPTION: the device has an electronic protection system against overvoltages.
RESPONSE: in case of excessively high voltage the system stops the pump. If an adequate voltage value is re-established, operation of
the pump is automatically restored.
CHECK: check the supply voltage
A9 LOW VOLTAGE ( * CHECK FAULT):
DESCRIPTION: the device has an electronic protection system against low voltage.
SYSTEM RESPONSE: in case of undervoltage the system stops the pump. If an adequate voltage value is re-established, operation of
the pump is automatically restored.
SOLUTION: check the supply voltage.
BLANK DISPLAY:
DESCRIPTION: blank screen.
SYSTEM RESPONSE: none.
SOLUTION: check the supply voltage. Check the state of the fuse
