6.7. PROGRAM PARAMETER
First of all, the program number has to be cho-
sen.
Program number : 03
Each program can be a part of an “
Irrigation
group
”. This avoids the irrigation of two programs of
the same group at a time. One of them will be at stand
by showing in its view the text “Postponed by priority”.
The programs assigned to the group “0” do not take
part of an association and avoid the postponement.
The “
security time between starts
” is used to
maintain minimum time between two starts. The secu-
rity is not taken into account when leaving the value at
0.
These functions are of utility, for instance, when
the irrigation start is ordered by sensors, reaching an
organized evolution of the irrigations.
P03 Irrigation : 0
Security time between starts : 03:45
Each one of the 35 programs has got 4 possible
determining factors in order to carry out start actions,
stop actions, irrigation or fertilizers modifications, ac-
cording to the following chart:
-
Type 01: Start when the sensor surpasses the pro-
grammed value.
-
Type 02: Start when the sensor is below the pro-
grammed value.
-
Type 03: Start by integrating the value of a sensor.
-
Type 04
: Start by digital sensor.
-
Type 05
: Conditional or temporary stop when the
analog sensor surpasses a pro-
grammed value.
-
Type 06
: Conditional or temporary stop when the
sensor is below a programmed value.
-
Type 07: Irrigation modification by integrating the
value of a sensor.
-
Type 08: Irrigation and fertilizer modification by in-
tegrating the value of a sensor.
-
Type 09: Fertilizer modification by integrating the
value of a sensor.
-
Type 10: To modify the irrigation in ratio to the va-
lue of a sensor (evapotranspiration- Eto,
ground moisture-cbars - %, etc).
-
Type 11: To modify the fertilizer in ratio to the value
of a sensor.
[ Types 1,2,3,7,8,9,10,11 are Program determining
factors option ]
The determining factors can be digital or analog
elements, which can influence the programmed values
in order to adapt them to the climatic or environmental
changes or changes of the installation itself.
This takes place in two stages:
1.
At “Parameters – Programs” the determining
factors that can affect the program and how
the determiner will be dealt have to be indi-
cated.
2.
At the beginning or at the determining fac-
tor in each program.
Type 1 and 2 determining factors
: Having the
option installed, irrigation programs will be started
when the analog sensor level (temperature, soil mois-
ture, etc.) reach a determined value. This value will be
asked at the irrigation program as well as the starting
time when pressing the “MODE” key.
The determining factor will be only taken into ac-
count when the irrigation is not taking place and when
sixty seconds have passed since the sensor value has
reached and maintained the starting value.
By answering “YES” to the “Generates a mes-
sage Y/N” question, a SMS message will be sent to a
mobile telephone, whenever the option has been in-
stalled. This question appears in all types of start and
stop determining factors.
P01 Det.factor 1, type : 02
Sensor: 04 Generate a message Y/N : Y.
Type 3 determining factor
: Having the option in-
stalled, irrigations by integration (total of sensor units
in relation to time) can be started. For example, we
can integrate with the solar radiation de vats/hour the
plant has received since the previous irrigation and
order more frequent irrigations in sunny days than in
cloudy ones.
The analog sensor number and a minimum level,
from which the integration will be allowed, have to be
entered. At the irrigation program, next to the starting
time and pressing the “MODE” key, the integration
value since the previous irrigation will be asked in
order to deal with a new irrigation.
P01 Det.factor 1, type : 03
Sensor: 01 Min.: 0200 Wm
2
Type 4 determining factor
: It allows the starting
of irrigation programs by a element connected to a
digital sensor with a starting programs function. Look
at [6.4.1 codes 36-43] sector.
Enter which start sensor functions out of the 8
possible ones will affect the program.
P01 Det.factor 2, type : 04
F. Start = 1 Generate a message Y/N : Y.
Types 5 and 6 determining factors
: They are
used to stop conditionally or temporarily an irrigation
ordered by a program whenever the analog sensor
value is not a reference value. Type 5 will stop when
the value surpasses the reference and type 6 when it
goes down.
