There is a timing which affects all filters equally:
the pause between filters. This timing is important to
recover pressures in the net and avoid overlapping in
the hydraulic valves.
Both a cleaning sequence and the outlets can be
started or stopped manually with the unit. The unit can
also be set at stop (deactivated).
The user can easily program all the parameter
and timing values of the controller.
The unit shows the state of the unit at all times,
indicating the filter that is working, whether it is
working, the state of the inputs and whether there is
any outlet which has been activated in a manual way
as well as showing whether the controller is at stop. It
also informs about the circulating instantaneous flow
and about the volume and time units that have gone
by since the last cleaning.
At the TOTALS function, the unit shows the
number of cleanings that have taken place due to a
"drop in pressure" and "volume" or "time". The total
water volume, which has circulated through the filters
or the time it, has been working, since the last time it
was set at zero are also indicated.
The unit has the following inputs:
- For the differential pressure gauge which
detects the drop in pressure in the filters, (necessary
for the starts by "drop of pressure"),
- For the detection of water flow through the
filters with a signal that comes from a programmer,
calliper, etc., (necessary for the starts "by time" and
for the total of hours that the filter installation has been
working),
-
For
the
volumetric
(necessary for the starts by "volume", information
about the instantaneous flow and volume total of
filtered water),

- For the detection of breakdowns in the
installation,
- For different options.
A timing for detection delay can be assigned to
the inputs, in order to avoid inadequate signals.
There can be three types of outlet: at 24 Vac, at
12 Vdc and at 12 Vdc for latch valves (with two or
three wires) with low consume.
MODELS AND OPTIONS
Models for 6, 12, 18 outlets.
-
220 Vac version and 24 Vac outlets.
-
12 Vdc version and 12 Vdc outlets.
-
Version with the equipment provided in a box with
-
transparent cover.
Version with the equipment prepared to build-in a
-
cupboard or a desk.
Option with outlets for latch valves (with two or
-
three wires) and low consume. Due to the fact that this
version has a low consume of the unit and its
electrovalves, it is very suitable for those installations
which work with a battery and which do not have a
diesel engine or a solar cells to recharge it.
Version for filters with cleaning and rinse. It can
-
have 2, 4 or 6 filters. Every filter uses three relays to
control the 5 necessary hydraulic valves. The
programmer will ask for every filter the cleaning and
rinsing time.
WARRANTY
The Agrónic filter controller meets all the norms set
by the EC.
The products created by PROGRÉS enjoy a two-
year warranty against all manufacturing defects.
Compensation for direct or indirect damage
caused by the use of the equipment is excluded from
the guarantee.
