1. INTRODUCTION
Agrónic 54 is a unit which regulates both the
Page
electrical conductivity (EC) of irrigation water, injecting
1
2 possible fertilisers, and its pH, injecting acid or base.
2
There are 3 formulas or programmes, which are
2
started by
3
corresponding inputs.
3
There are 2 versions, according to the way in
3
which the dosage is done: one with "pulsed injection",
3
which works on the solenoids, another one with
4
"analogical injection", which works on frequency
5
variators.
6
In the "by pulsed injection" version, to maintain
6
the CE, the unit applies every certain seconds, a dose
6 of every fertiliser, which is related to the desired
proportion between fertilisers and the programmed
7
reference. To maintain the pH the unit works in a
7
similar way.
8
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.
