Auto Pressure Control Pressure Loss

VADA - V-PC Auto Pressure Control
If the column of water between the pump and
the highest tap exceeds 15m, the unit cannot
be installed directly on the pump, it has to
be raised until the column of water between
the unit and highest tap does not exceed
15m. i.e. If column of water is 20m from the
pump, the unit must be place 5m higher than
the pump.
The pressure control is equipped with a
check valve to prevent the pipeline from
losing pressure.
Notapscanbeinstalledbetweenthe
pressure system and the pump.
PUMPPRESSURE
The pressure control is pre-set by the
manufacturer at a restarting pressure of 1.5
bar. The pressure produced by the pump
must be normally 0.8 bar higher than the set
pressure.
Before starting the unit, check suction and
ensure the pump is primed.
It is advisable to connect the pressure control to the
system by means of a flexible hose.
Safety valve preventing water emission in case of
diaphragmdamage.DONOTTOUCH.
It is imperative to install the pressure control with the
arrows in an upward position.
The pressure control can be installed directly on the
pump, or between the pump and first tap.
Installing the Auto Pressure Control Correctly
15m max.

1. Pressure Control Installation
The Vada Auto Pressure Control comes fully wired and is ready for use with the pump. Please ensure the pumps current rating is below 10 amps or
that the automatic pump control is configured so as the current to the unit is less than the maximum current rating of 10 amps.
Warning:Nevertaketheelectronicboardoutofthecontrolbox.Thewiringdiagraminsidethefrontpanelwillshowyouhowtomakecorrect
connection. Wrong connection will destroy the whole electronic circuit. If extending the cable used for connection it must be three wired with a
grounded end. It shall have the outer diameter at 7.5mm min and 8.5mm max. The two cables must be goose necked so that part of the cable is
lower than the position of the fixing nuts to reduce the chance of water running into the conroller, as shown in the figure below.
The 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.
2. Starting & Operation
Whentheunitisconnectedtothepowersupplyandpowerisavailable,thegreenLEDindicating“poweron”illuminates.TheyellowLEDilluminates
to show the pump is in operation. On initial start up the pump will run until the supply line is primed.
When a tap is opened the pump will start automatically and continue to run at constant pressure. When the tap is closed, the pump will run on for
a short period until the system is again pressurised and then stop.
Shouldthepumpfailtoprime,theredLEDindicating“failure”willilluminateandthepumpwillstop.Thisensurethepumpisprotectedagainstloss
of prime. It will be necessary to press the restart button to have the pump restart.
Should the system fail again, it is recommended the pump is isolated from the power, system pressure relieved and the problem investigated by a
suitably qualified person.
Once starting operation is achieved, the unit is programmed to perfrom all the pump control operations automatically. When particular operational
breakdownsoccursuchaswaterfailure,obstructionofthesuctionpipeetc.theunitrecognisesthebreakdownandthered“failure”LEDlightsup,
at the same time as a stop signal is sent to the pump to prevent damage 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“restart”button.
When using a generator to power the Auto Pressure Control, ensure the output of the generator is a full sine wave to mimick 240V.
