6.2. FILTER CLEANING PARAMETERS

The filters cleaning is another important service of

the Agrónic range which allows to clean periodical
and automatically the four possible groups of filters by
means of a sequenced cleaning.

Before configuring the values for the cleaning of

this sector, it is necessary to enter in the sector [6.3]
of “General outputs parameters” to configure the
number and the outputs of each group of filters.

Each group of filters is independent, in its con-

figuration and operation, to the others.

First it will ask which group the values will be en-

tered for.

Filters group number : 1

To apply the cleaning two times can be pro-

grammed, of utility, for instance, when there are both
rings and sand filters, or when there is a first filter
which gets dirtier than the other ones. In case of being
the cleaning time common to all the filters of the

group, the values of the second subgroup will be left
at 0.

Let’s see a configuration example of a filters

cleaning group: there are 8 filters. The 4 first have a 30

second cleaning time and the others a two minute
time.

Cleaning time: 030” subg. 1 : 01 to 04
Cleaning time: 120” subg. 2 : 05 to 08

The pause time between filters is the delay in the

starting of each filter’s cleaning.

The units between cleanings correspond to the

time or volume of water circulating through the filters
to make a new cleaning of them. The units will be in

minutes, cubic meters or liters, depending on what
programmed in the “Irrigation units” of the “Flow pa-
rameters” (6.5). The cleaning can also be started by a
differential pressure gauge connected to a digital in-
put. Whenever a filter cleaning takes place, the meter

of units between cleanings is reinitiated.

In order to avoid the filters cleaning by units, lea-

ve the value at 0.

Pause between filters : 04”

Units between cleanings : 02300

Answering affirmatively to the “Stop sectors when

cleaning” request, the sectors which have common

irrigation pumps assigned with those assigned to the
filters cleaning will temporary stop. Once finished, the
sectors will continue at the same point where they
stopped.

In order to avoid a continued filter cleaning, a

maximum number of cleanings can be configured.
When the programmed value is surpassed it enters in
the “Filter cleaning without control” malfunction. In
order to reactivate the cleaning go to the “manual”
function, “malfunctions” sector and stop it.

In order to count a cleaning as a continued one,

the time between one cleaning and another must be
of 5 minutes.

In order to avoid the control, leave the value at 0.

Sectors stop when cleaning : Y.
Nº maximum cleaning in a row : 3

At the following screen, the pumps and volume

meters are assigned to the filters group. With this the
next features are reached:



Count the time between cleanings when pumps
irrigating and coinciding with the assigned in
this sector, whenever at “Parameters – Flows”
the irrigation had been configured in units of ti-
me.



Count the volume between cleanings when pul-
ses of the volume meters coinciding with the
assigned here arrive, whenever at “Parameters
– Flows” the irrigation had been configured in
units of volume.



Start the pumps configured here when the stop
of the irrigation sectors in the filters cleaning
has been ordered.



Take into account the differential pressure gau-
ge correspondent to the group of filters, when-

ever that any pump of the ones assigned here is
set on.
