confidence in us which you have demonstrated in express-
ing interest or acquiring Agrónic 52.
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 52 is a unit which continuously mixes two
Page
waters in order to obtain a programmed conductivity, by
1
using one or two motorised valves.
2
There are 3 formulas or programmes which are start-
2
ed by external orders received by the corresponding inputs.
3
The programming can be done either by the expected
level of conductivity or by the opening percentage ex-
3
pected for every motorised valve.
3
Up to 2 motorised valves can be connected. Every
4
motorised valve has an outlet to open and another one to
4
close.
5
There is also an outlet for alarm.
6
Feeding of the unit at 24 Vac. Optionally, at 12 Vdc.
6
There are 3 inputs for the start of the programmes
6
and 1 input to detect breakdowns.
7
There is also 1 input for the conductivity sensor, with
7
a transmitter which is integrated in the unit circuitry.
8
The calibration of sensors is done with the keyboard.
It is easy to use and programme by means of three
keys and a LC screen with 14 millimetre-high digits.
There is a CE alarm, being possible to configure the
high value, the low one and the delay in the detection of an
irregularity.
Configurable delay for the detection of start inputs
and breakdowns.
It is possible to stop or not the programme which is
being working when there is an alarm.
The motorised valves can also be activated manually.
Configuration of the motorised valve which will con-
trol the water with more conductivity, as well as configura-
tion of the one which will control the water we want to
save.
It is possible to programme a minimum opening of the
motorised valves.
The unit is located in a poly-carbonate closed box.
Agrónic 52 follows the CE guidelines.
