ANALOG SENSOR PARAMETERS
Sensor: 1
Format : 2
In the section on formatting, the conversion from
the real values from the sensors (normally 4-20 mA) to
the values that are shown onscreen (temperature,
pressure, humidity…) is configured.
There are a total of 26 different formats. Formats
1 to 20 are set at the factory. Formats 21 to 29 are free
to be configured by the user.
The values which can be entered in each format
are:
Whole numbers of the value to display.
Decimal numbers of the value to display.
If the value can be negative.
The points of linearization to pass the value
read by the sensor (in millivolts) to the value
seen by the user (degrees, bars, %, etc.). To
change the text, use the arrow keys up or down.
There are up to 4 points of linearization.
Text that accompanies the displayed value
(units). To change the text, use the up and
down arrow keys. With the “MODE” key, you
can change between capital letters, lower case
letters and symbols. The “NO” key is used to
erase.

All these sensors are configured as 4 – 20 mA in-
puts (800 – 4000 mV).
In the sensor section, one format is related to one
analog equipment sensor. It first displays which of the
40 equipment sensors is going to be configured.
Sensor number : 01
A sensor can be connected to different elements
of the Agrónic 4000 system. In order to define it, use
the chart of the section 4.10.2.
Analog sensor 1.
Sensor number : 00000000
The measure unit (format) each sensor will use is
defined at the following screen.
Analog sensor 1.
Format : 13 00.0 mS
If it is necessary to correct the reading from a
sensor, a tare value can be entered: a positive one to
add to the sensor value and a negative one to subtract
from it.
Analog sensor 1.
Calibrate : +00.0 mS
Finally, it displays whether the sensor will be reg-
istered. Up to 14 sensors can be registered, saving a
reading on an average of every 10 minutes and a
maximum of 10 days. This register cannot be dis-
played on the Agrónic 4000, only on the PC program.
Analog sensor 1.
Record: Y.
The following items have to be taken into account
in the installations with sensors:
Use a screened cable when connecting the
sensors.
Lay the cable away from the power lines.
Try not to surpass the inputs voltage limits.
The evaporation value may come from a SMS
message
6.5. FLOW PARAMETERS
This section is used to configure the constant use
of a unit when programming the irrigation and the
fertilizers. Whenever the unit of this sector is changed,
it will be changed as well in the programs which have
not got a sector assigned yet, taking into account that
with the “T/V” key the irrigation and fertilizer units can
be changed when placing the cursor on the program
value, and per program.
The irrigation units can operate in hours/minutes,
minutes/seconds, cubic meters or liters.
Irrigation units =
hh:mm (0) mm’ss” (1) m3 (2) L (3) : 2
The fertilization units can be in hours/minutes,
minutes/seconds, liters, deciliters or centiliters.
(10dl=1L, 100cl=1L).
Fertilization units =
hh:mm (0) mm’ss” (1) L (2) dl (3) cl (4) : 2
The flow margins of each meter are used to de-
tect possible flow anomalies, in relation to the ex-
pected flow of the sectors related with the meter which
is irrigating at the moment. The maximum volume that
the controller can control is 650.00 m
3
/h in irrigation
meters, and 650.00 L/h in fertilizer meters. In installa-
tion parameters there is the possibility of increasing it
to 6500.0 m
3
/h o L/h. If the anomaly lasts longer than
the time stated in the “Detection delay”, the unit will
work according to what is set at “Stop type”.
