Look at examples of determining factors:
o
F=+07% 0.75 mm/d
, increase the irrigation a
7 % per each 0.75 millimeters/day of crop
evapotranspiration.
o
F=-05% 02300 Wh/m
2
, diminish the fertilizer a
5% per each 2300 watts of solar radiation ac-
cumulated since the previous irrigation.
o
F= -15% 05.0 L/m
2
, reduce the irrigation units
in relation to a 15% per each 5 liters of rain.
For each one of the previous examples have to
be taken into account the rest of the values that affect
the determining factors, to do so, look at the program
parameters section [6.7.].
The last values correspond to the operation
ac-
tive period of the program
, with the format from
day/month to day/month. Setting all the values at 0 it
would work the whole year. It allows values which go
from a year to another (example 01/11 to 15/03).
Pre/Pos= 010/030 F=+04%
01/06 - 15/07
When pressing the “MODE” key when the cursor
is placed at the
active period
units, it will show the
active period values. Its function is to limit the deter-
mining factors which start the irrigation to do it only at
the here marked timetable.
All the values that go from the end of one day to
the beginning of the next day are accepted (example:
22:45 a 06:00).
Pre/Pos= 010/030 F=+04%
10:00 - 18:30
The start by temporization or manual is not lim-
ited by the active timetable.
When a program is operated by activations, it has
to be taken into account that the ones which are left to
do will be cancelled when the program is left out of
the active timetable. In the “installation configuration”
it can be configured so that they are not cancelled.
Each program is formed by 12 sub-programs. If it
is not necessary to do an irrigation sequence, only the
first program will be given values. On the other hand, if
some sectors have to be automatically activated when
other end, values will be given to the following sub-
programs. If a sub-program has not got irrigation sec-
tors programmed or the irrigation value is “0” it will be
omitted in the sequence.
The values of a sub-program are the following:
P01-01 S33 05 .. .. .. .. .. .. .. ..
I=02:17 F1 0023 F2 0108 L
-- -- -- -- -- -- -- -- --
P01-12 S02 04 .. .. .. .. .. .. .. ..
I=01:08 F1 0017 F2 0083 L
At the first line the sector or
sectors
to be acti-
vated are asked. Each sub-program has the possibility
to accept up to a maximum of 10 sectors or irrigation
valves.
At the second line the
irrigation
(I01:08) and
fer-
tilization
(F2 0083 L)
units
that will be applied to the
previously programmed sectors are asked. If the con-
figured fertilizers number to be used is higher than 4, it
will show from the fifth on onwards on the following
screen.
P01-01 S33 05 .. .. .. .. .. .. .. ..
I=02:17 F1 0023 F2 0108 F3 0000 F4 0038 L
P01-01 S33 05 .. .. .. .. .. .. .. ..
I=02:17 F5 0000 F6 0009 L
The type of units will be configured at the Pa-
rameters sector but at any sub-program they can be
modified by using the “T/V”
key, both for the irrigation
or for the fertilization. To do so, press the key when
the cursor is placed at the value to be modified. It is
possible to work with different units between sub-
programs.
Time = 00:00 (hours : minutes).
Time = 00’ 00” (minutes seconds)
Volume = 0000 m3 (in irrigation)
Volume = 0000 L (in irrigation and fertilization)
Volume = 0000 dl (in fertilization)
Volume = 0000 cl (in fertilization)
The pre-irrigation and the post-irrigation take the
same values each sub-program has.
The way of applying the fertilizers will depend on
what programmed at the sector of Parameters, having
the possibility to be “in series” (one after the other),
“parallel” (all at a time) and for both types with propor-
tional or not application.
In the event of series fertilization, when several
programs are operating at the same time and have
different fertilizers assigned, the fertilizers will be in-
jected simultaneously. Thus, series fertilization may
give way to 8 fertilizers being injected in 8 different
programs.
If a “in series” and “proportional” application is
programmed, the proportion is configured in parame-
ters of
fertilizers
for each one of them, but, if the ap-
plication is “
parallel
” and “
proportional
” it is pro-
grammed in each one of the sub-programs, as can be
seen in the last line of this example screen:
I=0185 m

F1 10/03 F2 08/13
According to this, each fertilizer has two values,
an irrigation units one at the left of the bar, and a fertil-
izer one at the right of it.
If operation at both values by volume, the previ-
ous example would be: per each 10 m
3
of water, 3
liters, deciliters or centiliters of “fertilizer 1”, and for the
