10. ALERTS .
A1: LACK OF WATER ALERT.
Warning:
n
n Description: if ONEMATIC 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
n
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
n
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
A2: LEVEL SENSOR ALERT.
n Warning:
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
n
show the message for lack of water.
System reaction: the pump will remain stopped until level sensor detects water in the tank.
n
Solution: check tank.
n
A3: TRANSDUCER DAMAGED ALERT.
Warning:
n
Description: transducer damage is displayed on the ONEMATIC´s LCD screen. Contact the technical service when this alert was
n
triggered.
n System reaction: unit operation is interrupted.
Solution: contact with technical service.
n
A4: OVER-CURRENT ALERT.
n Warning:
n 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
n
attempt, it will be switched off until the damage is repaired.
n 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:
n
Description: ONEMATIC cannot detect current from the pump and has disconnected the same to avoid severe damaging. There are
n
three 10 A fuses. 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.
n
Solution: check the state of the fuses and replace as necessary. The winding of the motor and the pump consumption should also be
n
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.
A6: ACCUMULATOR ALERT.
n Warning:
Description: t he system periodically analyses the state of the accumulator of the hydraulic installation, however only in pressure -dependent
n
mode.
System reaction: the system will continue running even if accumulator pressure is insuficient, however, it is highly recommended to repair it
n
immediatly .
n Solution: the system has detected that the accumulator is damaged. The load of air, the condition of the membrane and the state of the
spherical housing should be checked and replaced if necessary.
BLANK SCREEN.
Warning: blank screen.
n
Solution: check electric supply as well as the position of the voltage selector. In case that no faulty conditions can be detected,
n
contactthe technical service.
Simultaneous alerts are displayed on the LCD screen successively every 3 seconds. All alerts can be acknowledged by pressing the On/off
push-button in manual mode.
WARNING: ONEMATIC has a volt-free contact with 1 A maximum intensity for the transmission of signals to different types of alarm equipment
(optical, acoustics, etc). See connection diagram.
