SUMMARY OF ALARMS
TYPE
If the system detects dry running during
A1
DRY RUNNING
more than 10 seconds, it will stop the
pumps and the
there is installed an external device as a
level sensor, when this one detects lack
of water it will stop inmediately the
pumps.The system will show the
message of lack of water.
A2
The system pumps are protected
OVER-INTENSITY P2_4
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.
A3 This device has an electronic safety
DISCONNECTED PUMP
system against short circuits for the
main pump as well as a 20 A fuse.
Secondary pumps are protected with 10
A fuses (see diagram 3)
A4 If the system is working in
ACCUMULATION
without the main pump, it analyzes
periodically the state of the expansion
tanks of the hydraulic installation.

excessive temperature is reached, the
own system leaves it out of service and
as consequence the main pump.
A7 The system has an electronic system for
SHORTCIRCUIT
protection against short circuits as well
as a fuse of 20 A.
A8 The system has an electronic safety
OVERVOLTAGE
system against overvoltages.
A9
This device has an electronic safety
UNDERVOLTAGE
system against too low supply voltages.

If led-light failure is flashing intermittently the device is verifying the failure. In case of being permanently bright the failure is definitive.
In case of simultaneous alarms, quit the automatic mode and go to manual mode, pressing the pushbutton "AUTOMATIC". Using key p will be displayed the
succesive alarms. If you want to exit from the menu press ENTER. To restore manually a device turned off by an alarm quit the automatic mode by pressing the
pushbutton "AUTOMATIC ON/OFF" and then press ENTER.
This device has a volt-free contact with 1 A of maximum intensity for the transmission of diferent types of signal (optical, acoustics, etc). See connections diagram
Fig. 3.
DESCRIPTION
ART will be activated. If

If an
SYSTEM REACTION
After 5 minutes ART system will start again the first pump during 30 seconds,
trying to restore the system. In case of persistent dry running, it will try it again
every 30 minutes for 24 hours. If after all these cycles , the system still detects
lack of water, pumps will remain permanently off until the damage will be
repaired.
In the case of having an external level sensor, if this device detects enough level
of water again, it will start up the system automatically.
When detecting the thermal failure, the affected pump will be automatically
excluded.
If the main pump has been excluded
Working) is activated and the secondary pumps will continue working until the
system will be pressurized. If the secondary pumps has been stopped and there
is a new demand of water supply, the system will try again to restart the
excluded pump. The control system will carry out 4 attempts in this
circumstances. If the system remain locked after the 4th attempt, the main
pump will remain definitively out of order and system will continue working
provisionally in EW mode until the damage could be repaired.
If a secondary pump is excluded
system will try again to restart the excluded 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 and system will continue working provisionally in
EW mode until the damage could be repaired.
The operating mode EW (Emergency Working)
system to continue running.
If there is not enough accumulation, the system will stop.
The device operation is interrupted.
The operating mode EW (Emergency Working) is activated, allowing to the
system continue working with secondary pumps. In the model with three
pumps, the auxiliary ones are alternated in each new operating sequence.
The pump remains stopped for 10". Then it starts again - 4 attempts. If the
problem is not solved, the pump will remain definitively out of order.
In case of overcurrent the system remains stopped during some seconds. Then
the operation is restored.
In case of undervoltage the system remains stopped until an adequate value of
voltage is reached. In this case the system is automatically restored.
The device operation is interrupted.
