
Activations, enables pulsed irrigations with activations separated by a period of time. Only in program 1.

Format in volume, for irrigations to operate in formats of 00000 m3, 0000.0 m3, 000.00 m3; for fertilizer
in 00000 L, 0000.0 L, or 000.00 L.

Type of fertilization, injects fertilizer in series application (one after another), or in parallel (all at the
same time).

Fertilizer units, in time, hours and minutes (hh:mm) or in volume (Liters). The units chosen here will be
the ones used in the irrigation programming.

Stop for filter cleaning, it is possible to temporarily stop fertilization while the filters are cleaned auto-
matically.

Latch valve, selects the type of latch electrovalve to connect the equipment to (3-wire, 2-wire or invert-
ed 2-wire), inverted 2-wire default setting.

Latch voltage, it is possible to set the latch trip voltage to 12 or 22 volts (22 V default setting).

Daylight saving time, to confirm the automatic change to the daylight saving time.
6. Communications, see the manual “Agrónic 2500 Communications Supplement”.
7. Language, the available languages are Spanish, English, French, Italian, Portuguese and Catalan.
8. Updating software, allows the Agrónic 2500 software to be updated by connecting it to a PC using a USB
cable.
9. Backup parameters, it allows you to save a copy of all the parameters and programs of the Agrónic in an
internal flash memory. This copy can be recovered when desired, leaving the computer with the same configura-
tion than when it was last saved.
6.9. DIESEL OPTION PARAMETERS
This option allows diesel pump motors and generators to be started up, stopped, and monitored for malfunc-
tions.
One device that must be connected is the oil pressure gauge of the pump; digital input 6 is reserved for
connection purposes. It has a double function: first, to detect whether the motor has started up and, once this is
done, to detect a possible pressure error.
The general parameters will ask for the preheating time prior to each
start-up attempt. This value is set to zero when a heater is not used.
To get the motor ready for operation, there can be up to four start-up
attempts, each separated by 30 seconds. Enter the required start-up
seconds. Setting the start-up time to zero will cancel out the attempts and
the control over the oil pressure gauge. This is used in facilities whose
diesel motors already have electronic controls.
The stop time is used to stop the motor by activating an electromag-
net, or an electrovalve to cut fuel. It is recommended to give this extra
time to ensure the stop has actually occurred.
The starting pump and end pump times are used when there is a
generator. The input time corresponds to the time elapsing between the
start-up of the diesel motor and the activation of the “Pump 1” output connected to the irrigation electro-pump,
which is enough time for the generator to be implemented. The end time corresponds to the time the generator
remains in operation when the irrigation is finished to allow for a final cool-down.
It is necessary to assign relay outputs for the StArt-up, Stop, Contact and Preheating. In models with the
“double voltage” options, it is not necessary to assign them, as they are always the last four outputs.
