9. ALERTS .
A1: LACK OF WATER ALERT.
Warning:
A 1
D R Y
Description: if ONEMATIC easy detects lack of water in the inlet of the automatic control unit for more than 10
seconds, it will stop the pump and the ART will be triggered.
System reaction: after 5 minutes ART system will restart the pump for 30 seconds, trying to restore the
system. In case of persisting lack of water, it will attempt another restart every 30 minutes for 24 hours. If, after
repeat attempts, the system still detects a lack of water, the pump will be permanently stopped until the
damage is repaired.
Solution: there is a lack of water in the inlet, which resulted in the safety system to be triggered: verify the
supply from the hydraulic network. The pump can be primed using the push-button START/STOP ( the AUTO
On/off LED light should be off; if not, press the push-button to disable it).
A2: LEVEL SENSOR ALERT.
Warning:
A 2
L E V E L
Description: if a float switch is installed in the inlet tank, it will inmediately stop the pump when it detects a lack
of water. The system will show the message for lack of water.
System reaction: the pump will remain stopped until level sensor detects water in the tank.
Solution: check tank.
A3: TRANSDUCER DAMAGED ALERT.
Warning:
A 3
T R A N S D U .
Description: transducer damage is displayed on the ONEMATIC easy´s LCD screen. Contact the technical
service when this alert was triggered.
System reaction: unit operation is interrupted.
Solution: contact with technical service.
A4: OVER-CURRENT ALERT.
Warning:
A 4
O V E R C U R .
Description: the pump is protected against over-current depending on the current value defined in the
configuration menu. These over-currents are generally caused by malfunctions of the pump or in the electric
supply.
System reaction: when a failure is detected, the system will attempt to restart the pump four times. If the
pump is still tripped after the 4th attempt, it will be switched off until the damage is repaired.
Solution: check the state of the pump; for example, the impeller could be blocked. Verify the current value
entered in the configuration menu ( it is always recommended to define current values as 15% above the rated
pump current). Check for damaged fuses. Once the possible problems have been solved, the pump is put
back into operation; then, the "INSTALLATION" menu (see chapter configuration) is displayed for entering
the adequate current values.
A5: DISCONNECTED PUMP ALERT.
Warning:
A 5
P U M P
Description: ONEMATIC easy cannot detect current from the pump and has disconnected the same to avoid
severe damaging. There is a 20 A fuse. In case of pumps with different consumption values, suitable fuses
must be chosen.
System reaction: the system will remain off until the problem is solved externally.
Solution: check the state of the fuses and replace as necessary. The winding of the motor and the pump
consumption should also be checked. Once the possible problems have been solved, the pump is put back
into operation; then, the "INSTALLATION" menu (see chapter Configuration) is displayed for entering the
adequate current values.
