Warning!
Never take the electronic board out of the control box.
¡WARNING!
The wiring diagram inside the terminal block will show you how to make correct connection. Wrong
connection will destroy the whole electronic circuit. Cable used for connection must be a three-wired one
with compulsory grounding end. It shall have the outer diameter at 7,5 mm. and 8,5 mm. max. One of
the leading end of the cable must be lower than the position of the fixing screws while the cable being
connected to the power as shown in the figure.
Th four screws on the panel board and the two nuts for fixing cable must be well fastened to avoid water
entering into the control box and damaging the electronic circuit.
The way of internal wiring connection:
The four screws
must be fastened
Inter
Please see above diagram, the above three cables:, blue, brown, yellow-green are input cable;
the below three cables, yellow-green, blue, brown are output cable.
Starting
When the unit is connected to the electrical network, the green "POWER ON" LED lights up and the yellow
led "ON" (pump in operation) indicates that the pump has been started. The pump continues to operate for
dozens of seconds enabling the system to fill in the pipes and to reach the required pressure.
If this lapse is insufficient, the red LED "FAILURE" lights up. In the event, keep the "RESTART" button presses
and wait, with a tap opened, until the red LED is OFF.
Once released the button and closed the tap, the unit stop stops the pump at its maximum pressure.
Functioning
The starting operation archived, the unit is programmed to perform all the pump control operations
automatically.
When particular operational breakdowns occur, such as water failure, obstruction of the suction pipe, etc...
The unit recognizes the breakdown and the red LED "FAILURE" lights up: at the same time a stop signal is
sent to the pump to prevent damages caused by its working in the absence of water.
Rectification of the failures that have caused the blockage, allows the system to be restarted by pressing
the "BUTTON"
This part must be lower
than fixing nuts.
