On the base of the Agrónic 2500 there are 6 inputs to connect up digital sensors (section [5.3.3.]). Different
functions can be assigned to them on the following screens.
IM
Irrigation meter
FM
Fertilizer meter 1 to 4. When fertilizing in series, there is
only one meter. In this case, the same input must be assigned to
each meter that has been enabled.
SC
Start cleaning. Used to connect a differential pressure
gauge and make cleanings by increasing the pressure between
the inputs and outputs for a group of filters. There is a 30-second
delay after the pressure gauge gives the command. To accept the
input, a program must be running an irrigation cycle.
TM
Temporary malfunction, causes current irrigation program to stop, but it lets the next sequence or
start continue as normal. Once the temporization is over, the sensor will be reactivated.
DM
Definitive malfunction, is what causes a total and definitive stop of the system until it is manually
reactivated by the user in “Function - Manual” [8.].
CS
Conditional stop, when activated, all the programs under way stop completely with their remain-
ing units intact. Once the stop is over, irrigation resumes at the same point. While in a conditional stop,
programs may begin and be placed on standby.
PS
Start programs, a digital sensor will begin the irrigation of one or more programs. The input will no
longer be accepted if the programs or their sequences have not terminated.
AL
Alarm, a digital sensor that is normally closed will send a SMS when the contact is opened.
When inputs have been assigned, the following associated values will be requested.
With the value per pulse in the irrigation or fertilizer meter, we indicate the volume to be counted per pulse
received. The units for both irrigation and fertilization run from 1 centiliter to 9999 liters.
The input allows a maximum of 5 pulses per seconds.
With the delay without pulse, minutes that it should be without receiv-
ing pulses from meter are shown in order to raise a definitive malfunction
(if it is an irrigation one) or a fertilization stop. Leaving it to 0, the malfunc-
tion is disabled.
For the rest of the stop, start or malfunction functions, a time in sec-
onds will be requested to delay the detection of the digital sensors con-
nected to the inputs. If the sensor disconnects the input, the temporization
will be reentered. This is used to filter out false events, such as a pressure
sensor triggered when the pipes are being filled.
Each general engaged in this section - either fertilizer or filter gener-
als - will request the allocation of an output. We must begin by providing
the last outputs the equipment has available to these generals, as the
sector outputs occupy to output 1 and so on.
