STARTING AND WORKING:
.........................................................................................................................
CAUTION:
- Never take the electronic board out of the control box. The wiring diagram inside the terminal block will
show you a correct connection. Wrong or loose connection will destroy the whole electronic circuit.
-
Cable used for connection must be H05 or H07 type with 3×1.5 mm section.
It shall have the outer diameter
at 8.9 mm min. and 9.2mm max. One of the leading ends of the cable must be lower than the position of the
fixing screws while the cable is being connected to the power as shown in the fig.
- The six 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.
FUNCTION:
- The control is programmed to start and stop the pump operations automatically.
- Its feature of water-shortage protection can protect the pump from being damaged during dry running.
Also it has a built-in delayed auto-start timer which attempts to restart pump every 1 hour, 5 hours and 24
hours for a period of 4 minutes after dry-running protection till 24 hours when if there is still no water in the
pipe, the whole program will repeat every 24 hours. Timing system inside can be set as per customers'
requirements.
- Rectification of the failures that have caused the blockage allows the system to be restarted by pressing
the “restart” button for more than 2
seconds. Keep button “restart” pressed can stop the pump during its
operation and resume its work after stopping.
FUNCTION:
-
When the control is connected to the electrical network, the green led “power on”
lights up and the yellow
led “on”
(pump in operation) lights 2-4 seconds later indicating that the pump has been started.
- The pump continues to operate for 8 seconds enabling the system to fill in the pipes and to reach the
required pressure.
If this lap
se is insufficient, the red led “failure” lights up. In this event, keep the “restart” button pressed and
wait with a tap opened until the red led is off. Once the button is released and the tap is closed, the control
stops the pump at its max. Pressure.
