PRESENTATION
We wish to take this opportunity to thank you for
the confidence in us which you have demonstrated in
expressing interest or acquiring Agrónic 54.
This confidence, for our part, stimulates our
efforts to meet and surpass the expectations of our
clients to justify the traditional quality of our products.
This Manual will allow you to see the capacity of
the unit as well as its installation and use.
However, if after reading this you still have any
doubts, contact us and we will happily answer them.
1. INTRODUCTION
Agrónic 54 is a unit which regulates both the
electrical conductivity (EC) of irrigation water, injecting
2 possible fertilisers, and its pH, injecting acid or base.
There are 3 formulas or programmes, which are
started by external orders received by the
corresponding inputs.
There are 2 versions, according to the way in
which the dosage is done: one with “pulsed injection”,
which works on the solenoids, another one with
“analogical injection”, which works on frequency
variators.
In the “by pulsed injection” version, to maintain
the CE, the unit applies every certain seconds, a dose
of every fertiliser, which is related to the desired
proportion between fertilisers and the programmed
reference. To maintain the pH the unit works in a
similar way.
In the “analogical injection” version, to maintain
the CE and/or the pH, the unit changes the injection
speed of the engines until it gets the programmed
references.
In the version with pulsed injection, there are
outlets for 2 fertilisers and 1 acid or base.
In the version with analogical injection (0-10
Vdc), there is an outlet for fertiliser and another one for
acid or base.
In both versions, there is also a general outlet
and another one for alarm and/or agitator.
Feeding of the unit at 12 Vdc and outputs as well
to 12 Vdc.
Outlets at 12 Vdc in the version with pulsed
injection and at 0-10 Vdc in the version with analogical
injection.
There are 3 inputs for the start of the fertilisation
programmes and 1 input to detect breakdowns.
There is also 1 input for the conductivity sensor
and 1 for the pH sensor, with a transmitter, which is
integrated in the unit circuitry.
The calibration of sensors is done with the
keyboard.
It is possible to programme three different crops.
The EC reference, pH reference and the proportion of
two fertilisers to be applied (this is in the version with
