Progres AGRONIC 4000 Instruction Manual page 21

It is important to give this value when doing the
control by lack of flow.
The Agrónic 4000 allows us, as well, to work with
the irrigation counter by frequency, asking for the
cycles per liter the counter sends. At the counter
specifications the cycles per liter in relation to the di-
ameter of the pipe line will be indicated.
For the Fertilizers counters (codes 15 to 22 and
27 to 34), the operation philosophy is the same as that
for the irrigation ones, with the difference that the
pulse value is in centiliters (100 centiliters = 1 liter),
from 1 to 1.000 centiliters. When operating by fre-
quency, the cycles have to be entered per each centi-
liter (cl).
Functions 23 to 34 of the frequency counters can
only operate with inputs 1 to 7 of the Agrónic 4000
base.
The "Rain gauge" function, number 35, is used
to count the liters per m
enter the value corresponding to each pulse given by
the rain gauge at the "liters per pulse" question. Fur-
ther on we will see it can be used to condition the
irrigation and for the history record. The digital input
that has to be used is number 12.
A total of 8 inputs, with function codes 36 to 43,
are configured for the "Programs starting", will set
the starting of an irrigation program configured to be
conditioned by the input (section [6.7] of Parameters-
Programs). The question "Stop Y/N" allows answering
"YES", to stop the program by its input when discon-
necting it, and with "NO" it will only do the start, finish-
ing when the application of time or volume pro-
grammed ends.
6.4.2. Analog inputs
The Analog inputs sector has to be chosen at the
"Parameters-Inputs"

The unit offers to control up to a total of 76 differ-
ent sensors. Each one will be configured an input
where the units of the magnitude to be measured, the
input voltage levels, the screen margins and the cali-
brate will be connected.
Sensor number (1 – 76) : 02
A sensor can be connected to different elements
of the Agrónic 4000 system. In order to define it, use
the chart of the section 4.6.3.

This allows us to avoid the limitations of the sen-
sors type. Each one of the Analog inputs can be con-
figured depending on the sensor needed, all the
same, all different, or mixed.
For each sensor the voltage margins the input
gives have to be configured and then the correspon-
dent reading the screen will show. At the following
example, we see that a radiation sensor with a 4-20
mA input connected to a radio module will generate a
0.4 V voltage for 0 Wm 2

The following items have to be taken into ac-
count in the installations with sensors:
• Use a screened cable when connecting the
sensors.
•
Lay the cable away from the power lines.
