4.4.2. Latch option
The low consume of the equipment (0.12
watts/hour), and its latch electrovalves, make this op-
tion suitable for those installations which work with
battery. It is not indispensable, but a small solar panel
can be mounted to avoid the normal manual loading
of the battery.
To reduce consumption, the controller has a sys-
tem which switches the screen off when the keyboard
is not in use. To activate the display, simply press any
key on the Agrónic.
A. LATCH ELECTROVALVES WITH TWO CABLES
This electrovalve model works reversing the po-
larity between the two cables, to activate or deactivate
it.
One of the cables is to be connected to the outlet
common “C” and the other one to the corresponding
outlet.
If the electrovalve does the opposite of what the
controller has ordered it to do, it would be necessary
to reverse the cables that are connected to the com-
mon and outlet.
B. LATCH ELECTROVALVES WITH THREE CABLES
This models have a bridge in the right superior
part of the base card to change the working voltages
to the outlets (see indicative stick). Without the bridge
the outlets are working to 12 Vdc and with the bridge
installed they will have a voltage near to 24 volts.
From the company the units are delivered with the
bridge connected. The voltage depends on the type of
solenoids, by this, it can be changed depending on
your needs.
Also it is included for this version a diode box, to
which two of the three cables, the red and the black
one, belonging to each solenoid have to be con-
nected. The red one will be connected to the group of
terminals linked to the red cable which goes to the
controller (start common). The black one will be con-
nected to the other group of terminals (stop common).
The order of the sector numbers is not taken into
account in the terminals of the diode box.
Example of connection:
The other cable, normally white, will be con-
nected to the controller, to the outlet corresponding to
its sector or to the “M” general valve outlet.
4.4.3. Two pump option
In this option the second pump or general valve
2 will be connected to the last outlet of the controller.
A group of correlative sectors is assigned to
every pump, pump 1 is for the group of the first sec-
tors and pump 2 for the rest.
This assignation will be done in the configuration
of the installer.
4.4.4. Installer configuration
To go to installer configuration, follow the next
instructions: In function 3, ”Parameters”, pressing
“ENTER”, and pressing “9” and “ENTER”, then it is
needed to enter an access code.
Continuously, it will ask several question that it
only must be entered when it will necessary in order to
not erase any data or cause any malfunction in the
unit or in the installation. Pressing only the key “EN-
TER” it will go through the question without doing
anything.
The question are asked like this:
-
“Ram to 0”, answer with “YES” to erase all the pro-
grams information in course, anomalies and totals.
-
“Eeprom to 0”, to erase all programs and parame-
ters.
-
“M1 Sectors”: we will indicate the number of sec-
tors that will activate engine 1, the number entered
here will correspond to section 1, the rest are ex-
cluded or activate engine 2 in the case of the 2 en-
gine option.
-
“Sector limit”: by default a maximum of 8 sectors
are allowed to act simultaneously, enter the appro-
priate value to reduce this.
-
“Fertilization, 1: series 0:parallel” entering a 1 it will
do series with one fertilizer after the other, with 0,
several at once.
-
“Fertilizers stop” To stop or not the fertilization
while the cleaning filter is carried out.
-
“Conditional stop is System stop”, when the condi-
tional stop will take place it will work like a system
stop (Function-Manual), with this function it keeps
discounting the irrigation program time, but without
deactivate the outlets.
-
“Frequency h:mm”, answer “YES” if you want the
activation frequency in hours and minutes; if you
answer “NO”, the frequency will be in hours.
Pressing “ENTER” again, it goes back to view, in
the main screen.
