General Outputs Parameters - Progres AGRONIC 4000 Instruction Manual

The unit allows to do a cleaning of the pipe lines
and injector with water at the end of each fertilizers at
the series application or at the end of them all in the
parallel one. If no cleaning is desired, leave the clean-
ing seconds at 0.
Fertilizer end cleaning : 018"
Each fertilizer can have its associated mixer, with
independent pre-mixing set on mixing and stop mixing
values.
Mixer 1 Pre-mixing : 035"
On/off mixing : 015" / 120"
The pre-mixing will enter when the irrigation in the
pre-irrigation units start. If pre-mixing is not desired
leave the value at 0.
The mixing will enter when starting the corre-
spondent fertilizer and will constantly act during the
whole application of the fertilizer if value is only given
in the set on seconds. If value is only given to the stop
seconds, there will not be mixing. Programming the
set on and stop temporization, the mixing will be in-
termittent.
At the proportional fertilization modality, the mix-
ers will act without having in consideration the pauses
of the fertilizer.

is necessary to have it discharged and to have the

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"
Cleaning time: 120"
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 input. When-
ever a filter cleaning takes place, the counter of units
between cleanings is reinitiated.
In order to avoid the filters cleaning by units,
leave the value at 0.
Pause time 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
sub-g. 1 : 01 a 04
sub-g. 2 : 05 a 08
