1. BASIC FUNCTIONAL DESCRIPTION
This equipment is for the control of the irrigation
system, fertilization, fertilizer mixing, pumps and the
cleaning of the filters, with the detection of malfunc-
tions and visualization of data.
There are models with 6, 12, 18, and 26 inde-
pendent outlets plus 5 signal inputs.
Programmable for time or volume.
IRRIGATION
The system has a capacity for 31 independent or
sequential programs.
Programming can be for daily or weekly action or
with several activations every certain period of time on
the program number 1.
Up to 8 sectors can be operated simultaneously.
Grouping sectors together to simplify program-
ming.
Also manual activation and deactivation of pro-
grams, outlets and filters.
Irrigation program starting by input connected to
an external sensor, being able to do an irrigation se-
quence to be disconnected in manual mode.
FERTILIZATION
The equipment can be configured from 0 to 4 fer-
tilizers, in separate tanks, with the following configura-
tion possibilities:
- post-irrigation minutes.
- separation minutes between fertilizers.
- fertilizers pump, when there are more than one fer-
tilizer tanks.
- mixers for each fertilizer tanks.
- pre-mixing minutes.
- continuous, intermittent or stopped mixing while it
fertilizers.
The value of application of each fertilizer can be
programmed independently for each program.
The fertilizers can be applied in “series” one after
the other with only one injector, and if it is working by
volume only one counter.
Also can be applied in “parallel”, several fertiliz-
ers at once, with one injector for everyone, and always
by time.
PUMPING
The system can govern an electro-pump or a
general valve. To avoid problems of the water hammer
in the pump, special temporization sequences are
provided between the opening of the sector valves
and the starting of the pump, and also between its
stopping and the closing of the valves. The same ap-
plies to the changes of sector.
In diesel engine (optional) the unit realize a com-
plete control, with several start attempts, pre-heating,
automatic stop, malfunction detection, etc.
CLEANING OF FILTERS
This can be configured from 0 to 9 filters, with
variable washing time. Pause time between filters.
The washing sequence can be started by the
pressure difference and/or the time or volume of water
circulation.
Irrigation sectors can be stopped while filters are
being cleaned.
While the cleaning is carried out, the fertilization
is stopped.
ALARMS
By means of corresponding sensors, the equip-
ment detects malfunctions and acts accordingly, on
the basis of pre-established parameters, meanwhile
leaving a visual record (the input signal may be de-
layed).
The clock can be set to stop or not, in case of
failure of the electricity supply.
There are five input signals, which can be config-
ured for the following functions: irrigation volumetric
counter, fertilizer volumetric counter, differential pres-
sure gauge of filter cleaning, temporary malfunction,
general malfunction, conditional stop and program
starting.
VISUALIZATION
Complete visualization in 40 character alphanu-
meric LCD screen and a 14 function key waterproof
keyboard. All information concerning one program is
displayed on the screen.
You can consult, correct and erase by programs.
While a program is being executed, all information
concerning it is being displayed.
It controls and registers electricity supply cuts,
simultaneous working of more than eight sectors, the
overlap of two or more programs with fertilizer, exter-
nal malfunctions with general or temporary stop, etc.
There are counters for the totals of the units of wa-
ter and fertilizer application for each sector, as well as
another general counter for water and fertilizers.
