1. Introduction
The DREAM 2 irrigation control system is the second generation of the well-known
DREAM family.
Additionally to the outstanding features of the DREAM system, the new generation
now offers internet communication so that users of the DREAM 2 system can access
their controllers from everywhere, anytime.
Users are offered two options for accessing the system: one known as the
CONSOLE which is a software package that has to be installed on a PC, the other is
just an internet site called the SPOT which does not need any loading and is meant
to be used on CELLULAR PHONES and TABLETS.
Both options enable the users to login to the SERVICE which is a sophisticated
software package located somewhere in the cloud acting like a mediator between
users and their controllers.
On the other end there are the controllers that also login to the SERVICE and stay
online. The SERVICE will repeatedly interrogate all the online controllers in order to
keep its DATA BASE up to date, so that users interested in some information about
their controllers, can find it in the DATA BASE.
The aim of the following manual is to describe the features of the DREAM 2
controllers and teach the users how to program it using the local MMI of the
controller.
Prior to start using the controller in any specific facility, a configuration procedure
must be executed in which the image of the controller is defined. In this manual we
assume that the configuration procedure has been fully completed either by using
the “Image Maker” of the CONSOLE or by the local MMI as explained at the
"DREAM installation guide".
For learning how to use the CONSOLE software, see the “DREAM 2 CONSOLE
guide".

1.1 The Key-board description
1.2 How to Switch-Up and Shut-Down the system
Switching up and shutting down the DREAM 2 controller are activities that deserve
some explanations:
Switching up the DREAM 2 from a switched off state is done in 2 steps:
1. Turning ON the Power Switch
2. Pushing the Start button
About the Power Switch and Start Button see the paragraph of the Power
Supply Board below.
Each time the software is restarted there will be some introductory screens
displayed, then the System manager screen (described below) will appear for a
few seconds and eventually the Main menu of the DREAM application will be
displayed. The user should wait patiently until this stage is reached.
Function keys-F1, F2,
F3, F4 (from left to right)
handle position
dependent functions.
The functions are
specified above the keys
at the Function bar of
each screen.

The internal structure of the DREAM 2 is very much like the structure of a desktop
personal computer that has an operating system which handles multiple applications
simultaneously. This kind of activity is naturally involved with opening of multiple
files as required by the active applications. As in PCs, cutting the power before
closing the open files may be a harmful action and therefore should be avoided. For
this reason we are not supposed to turn off the power switch of the controller before
the software was commanded to shut down.
The software Shutdown button is located at the Function Bar of the System
Manager screens, which can be reached from any of the DREAM 2 application
screens, by pushing simultaneously the PgDn (˅) and PgUp (˄) buttons.
Pushing the F3=Shutdown button is the only safe way for shutting down the
DREAM 2 controller. Shutting down takes time, it is necessary to wait until the lights
on the CPU board turn off. Only after the lights on the CPU went off, it is safe to
switch off the Power Switch (see below).
The Shutdown software key turns the DREAM 2 system OFF.
The Reboot software key turns the DREAM 2 system OFF and then ON
again.
The Reboot and Shutdown functions are activated by pushing the red function
keys located underneath the Function Bar of the screen. Both functions preserve all
the data included in the controller except the statuses and left quantities of
programs.

1.3 The Power Supply Board
In the following paragraphs we are going to have a look inside the box of the
DREAM-2 controller, although the information may seem to be a little technical, we
think it can be useful if the user gets familiar with the functions of the switches, the
LEDs, the fuses and some main components of his system.
When the Power Switch is off, only the yellow LED should keep on lighting,
indicating that the charging of the backup battery continues.
When the Power Switch is turned on, some more LEDs of the power supply board
will start lighting.
The red LED indicates that 24v AC arrives to the system from the transformer (in
AC systems only). If this does not happen, the power from the mains and the Main
Power Fuse have to be checked.
As mentioned above, the yellow LED indicates that the charging voltage (13.9v
DC) for the backup battery is generated. If this LED does not light, check the
Charging Fuse. The backup battery should never left to be deeply discharged, it
may harm the battery, therefore if the charging source is expected to be
disconnected for a long period, the backup battery has to be disconnected as well,
otherwise when the charging is restarted, the deeply discharged battery may draw a
high charging current that may blow the Charging Fuse (F3).
The green LED indicates that the 12v DC arrives into the system. The 12v DC is
used for feeding all the electronic boards of the system; it may be generated either
Power Supply Board
Main power fuse
Charging fuse
12v DC fuse
Power switch
Start button
LED - 24 v AC
LED - Charging
LED - 12 v DC
LED - USB
Local I/O interface
RF interface
Local I/O module

- 8 -
from the charging device or from the backup battery, when the charging device is
off. In case of AC systems the charging device is the transformer, while in DC
systems it is the solar panel. The system is protected from excess current
consumption from the 12v DC source, by the 12v DC Fuse (F2).
Important remark: The charging current passes through both the Charging
Fuse and the 12v DC Fuse, so if for some reason the 12v DC fuse is blown there
will be no battery charging, although the charging voltage exists (yellow LED ON).
The red LED of the USB will start lighting only after the Start Button is pushed,
indicating that the system is now up and running. Together with the USB LED of the
power supply board, the red LED on the Mother Board and the three red power
LEDs on the CPU Board ███will start lighting as well.
1.4 The CPU board
Looking underneath the front panel, at the back of the LCD display we are going to
find the CPU Board which is the brain behind all the activities of the controller. Let’s
get familiar with some of the components on the CPU board:
CPU board
Cellular modem
The CPU chip
Lithium battery
Ethernet card
Buzzer
Reset button
LCD contrast
adjustment
The power ON
indication LEDs
Remote I/O
communication

- 9 -
When the DREAM 2 application starts running, a few activities start in parallel:
The LCD display connected to the CPU board will start showing some
introductory screens until arriving to the Main Menu.
The CPU starts scanning all the Interfaces second by second, sending them
the required status of the outputs receiving back the status of the inputs.
This activity is indicated by blinking of the REMOTE I/O communication
LEDs on the CPU Board and on each of the Interfaces.
Right after starting up the DREAM 2 application, the controller starts looking
for its host server on the Internet, in order to login to the service.
1.5 The concept of the internet communication
The DREAM 2 has 3 options for accessing the internet:
Using a Cellular Modem supplied by Talgil and plugged into the CPU board.
Using an Ethernet card for connecting to a Local Area Network.
Using a USB Netstick plugged into the motherboard.
The controllers after power up use their internet link to login to the service and stay
online.
As mentioned above, users have two options for accessing the system: one option is
the software package called CONSOLE and the other is the internet site called
SPOT.
Both options enable the users to login to the SERVICE which will coordinate
between users and their controllers. Additionally the SERVICE contains a large
DATA BASE that stores all the information about all the controllers and the
ADMINISTRATION software that decides about who is permitted to access which
controller.
The Server will interrogate all the online controllers repeatedly in order to keep the
DATA BASE up to date, so that users interested in some information about some
controllers, can find it in the DATA BASE.
USB Netstick

- 10 -
The drawing below demonstrates the physical layout of the communication between
users and targets (controllers) in the DREAM 2 system.
For setting up the internet communication there are some parameters to be defined.
The setting of these parameters is the job of the technical person in charge of the
system installation. Those who are interested can find information in the chapter
dealing with the SYSTEM MANAGER screens in the Installation Manual of the
DREAM 2.

- 11 -
1.6 Finding your way inside the DREAM
The MAIN MENU of the DREAM includes 8 subjects represented by 8 icons as
shown below. Underneath each icon there is a SUBMENU through which we can
reach any of the screens included in that subject. Selecting any of the subjects is
done by placing the cursor (black background) on the desired icon and hitting the
ENTER key. For getting back to the MAIN MENU from any screen use the key at
the bottom rightmost corner of the numeric keypad.
Having a closer look at the numeric keypad we shall see that above each key there is
some additional printing, this is to indicate that each key while being in the MAIN
MENU can act as a shortcut to the screen associated with it.
MAIN MENU
F2=Aboutkey

- 12 -
Behind any of subjects of the MAIN MENU there is a submenu that contains a list of
screens. The horizontal movements between the screens is accomplished by the
function keys F1 = and F4 = . Generally, the horizontal layout of
the screens resembles the order of the subjects included in the submenu, so the user
can use the and to pass through the screens of a selected subject.
STATUS –showing current statuses of the
system and its components.
IRRIGATION –supplying tools for defining
irrigation programs, including tools for
monitoring the irrigation process and tools for
intervention when necessary.
PARAMETERS –dealing with defining
supplementary parameters related with the
irrigation and fertigation processes.
RESULTS –showing reports and
accumulations resulting from the system's
activity. The reports can be sorted and
viewed in various contexts.
CONSTANTS –setting the constant
parameters of all the system components.

- 13 -
UTILITIES –dealing with special functions
that support various system activities.
FILTRATION –handling the filters flushing
programs.
SETUP –contains all the necessary activities
involved with the system configuration and
setup.
The contents of the MAIN MENU and the
SUBMENUs may vary according to the
relevance. For example, if no filters are
defined, the subject “FILTRATION” will not
appear in the Main Menu.
1.7 The “ABOUT” screen
Being at the MAIN MENU we can use the F2=About key to reach the following
screen:
The About screen contains some valuable information and enables executing some
useful commands:
This is the place where we can select the language we want to use. By hitting
F2=Change key we shall get a window with a list of languages to select
from.
To change the
language push
F3=Change

This is the place where we can try and refresh the communication with the
Server in case it is lost. Use F4=Serv.
This is where we can see the ID number of the controller.
This is the place where we can check the status of communication with the
server.
This is where we can see the version of the software loaded into the
controller.
Additionally we can see the current date and current time and the date of last
configuration.
2. Defining Irrigation Programs
Irrigation programs are defined in 3 steps:
1. Defining the IRRIGATION SEQUENCE which specifies the sequence of
valves to be irrigated by the program.
2. Defining the WATER DOSAGE and FERTILIZER DOSAGE per each
member of the sequence.
3. Defining the IRRIGATION TIMING of the program, when the program will
be activated. Sometimes instead of irrigation timing programs will be
activated by conditions.
When only the first step is defined the program is considered NOT READY, it cannot
be activated, but after completing the second step, the program is considered
INCOMPLETE, it will not start automatically, but it can be manually started. For a
program to be ready for automatic start, step 3 must be completed as well.
2.1 The Irrigation Sequence definition
Any irrigation program’s definition starts with defining the sequence of valves to be
irrigated by the program. For a new program definition, the cursor must be located
at the program number field and then, pushing the function key F3 = “Progs”
enables execution of commands related with programs editing. Select the option
“New”, the system will respond by suggesting the next free number for the new
program, the suggested number can be accepted or changed.
The sequence of valves can now be inserted. To indicate the end of the sequence
definition, use the ENT key.
The cursor located
at the program
number field

- 15 -
When the system contains more than a single irrigation line, valves will be referred
to by specifying both the line number and the valve number separated by a dot, as
shown in the example below, otherwise, valves are referred to by their ordinal
number only.
The sequence may include not only individual valves, but also predefined Groups of
valves (G1, G2 etc…).
The Groups definition can be found under the subject
When the system contains several water sources (A,B,C,…F), the user may select the
desired water source for each valve/Group by pushing F4 = "Src", otherwise the
system will select the default water source of the specified line.
The order by which the valves will be operated is defined by use of the following 3
symbols:
- SEQUENTIAL OPERATION - one valve after the other.
- TEMPORARY GROUPS - valves of the same line to be irrigated together
and CONSTANT GROUPS with a common dosage.
(must be enabled at DEALERS DEFINITIONS)
- STARTING TOGETHER - coordinated start of valves with individual
dosages. The valves may belong to different
irrigation lines. This feature is especially useful
when central fertilization is required. (must be
enabled at DEALERS DEFINITIONS)
The following picture shows an example sequence.
3.2B> 3.3B& 3.4B> G1A> G2A> 2.5A+2.6A+4.1B
The sequence above should be interpreted as follows:
First, line 3 valve 2 (3.2B) will irrigate from source “B”and when finished, line 3
valves 3 and 4 (3.3B&3.4B) will irrigate from source “B”, then Group 1 (G1A) from
source “A” followed by Group 2 (G2A) from source A. Eventually line 2 valve 5, line 2
valve 6 from source “A” together with line 4 valve 1 (2.5A+2.6A+4.1B) will irrigate
from source “B”.
Program status
Group 2
Line 2
Valve 5
Source A

- 16 -
Notice that :
Combining valves into temporary groups by “&” symbol can be done only
when the valves belong to the same irrigation line. The valves of the
temporary group will share the same water and fertilizer dosage.
Constant Groups (G1, G2…) cannot be combined by “&” or “+”.
Valves combined by “+” will start together at the same time but each
valve will have its own water dosage. As for fertilization, if the valves are
of the same line, they will share the same local fertilizer dosage and if
there is central fertilization, then the fertilizer dosage will be common to
all the valves combined by “+”.
The sequence defined at the local MMI of the DREAM 2 may contain 28
members at the most. However longer sequences can be defined through
the CONSOLE or the SPOT, but then they will not be editable through
the local MMI.Using long sequences must be enabled at the DEALERS
DEFINITIONS.
2.2 The Water Dosage definition
Each member of the sequence must have a water dosage defined in order to be able
to irrigate. In the dosage definition screen the sequence members are arranged in a
vertical order, the movement to the next or former member is done by the PAGE UP
() and PAGE DOWN () keys.
The dosage definition process starts with the selection of the dosage mode. For
selection of the water dosage mode place the cursor at the dosage units field. The
following dosage modes are supported:
hh:mm:ss –by time
m3 –by volume
m3/area –by volume of water per each unit of area
evaporation –by volume calculated from the accumulated evaporation
since last irrigation
evaporation time –The volume calculated from the accumulated evaporation
is divided by the nominal flow to obtain the needed
irrigation time.
by volume by time by evaporation
The dosage units field

- 17 -
Notice that :
Dosage by volume will be available only if the irrigation line or the water
source in use have got real or virtual water meters.
When irrigating by evaporation there is no planned value to be inserted, and
when working by m3/area the planned value actually contains the planned
amount per area and not the total amount to be irrigated. However, in both
cases, the total amount to be irrigated will appear as a calculated value. For
detailed explanation of dosage by evaporation and dosage by volume per
area, see the paragraph of Special dosage modes below.
The function of the various fields is as follows:
There is an option to define a special dosage of “water before” for the first Local
fertilizer, to make it different from the others. This option must be enabled through
the DEALERS DEFINITIONS.
Coordinated start of members of a sequence using the “+” sign, is meant mainly for
coordinating the fertigation of various valves in order to eliminate contradicting
demands of water and fertilizers. In that case, the system does not permit individual
central fertigation jobs but is dealing instead with a common fertilizing job shared by
all the coordinated members. Therefore when the option of "starting together" of
valves with the “+” sign is enabled, the definition of the water before will be made at
the common fertilizer dosage screen instead of in the water dosage screen and
hence the appearance of those screens will be slightly different.

2.3 Special Dosage Modes
Within this topic we shall explain the Dosage by evaporation and Dosage by
volume per area.In order to be able to use these special dosage modes, they
must be enabled through the DEALERS DEFINITIONS. Both of the two dosage
modes are meant to save the calculation effort when defining the amount of water to
irrigate.
Both methods are making use of the information about the area covered by each
valve, which is part of the VALVES’CONSTANTS.
The table contains both the area covered by each valve and a factor in % by which
the calculated amount will be multiplied. The factor is meant to represent the special
demand of the particular crop. The area is expressed in the units selected at the
DEALERS DEFINITION.
2.3.1 Dosage by Evaporation
When dosing by evaporation, the amount of water to be irrigated by each valve is
calculated automatically, relieving the user from the necessity of calculating and
defining the dosages per all the valves day by day.
The calculation takes into account the number of days since the last time the specific
valve was irrigated. Summing up the total evaporation during the elapsed days, data
taken from the evaporation table of the last 16 days (see the topic of Evaporation
at the paragraph of Irrigation/Fertigation Parameters), the sum is then
multiplied with the area covered by the specific valve, the result we get is the total
amount of water lost by the specific area during the specified period. Finally the
result is multiplied by the factor in % that represents the specific needs of the crop.
This final result is the amount to be irrigated.
Notice that if the irrigation program is a cyclic program of "n" cycles, each cycle will
irrigate the amount of the final result divided by "n".

- 19 -
EXAMPLE: let's assume that the specific valve was irrigated 3 days ago. The
evaporation of the last 3 days was 1.2, 1.3 and 0.8 mm which results in a total of
1.2+1.3+0.8= 3.3 mm. let’s assume that the area covered by the valve equals 50
Dunam (50,000 m2), therefore the amount of evaporated water is 3.3 x 50 = 165 m3.
If the crop factor is 80 % the amount to be irrigated is 165 x 0.8 = 132 m3. If the
irrigation has to be done in 2 cycles, each cycle will irrigate 132/2 = 66 m3.
The system offers the option of dosage by “Evaporation time”which uses actually
the same calculation method explained above but the final result is converted into
time units by dividing the volumetric result with the nominal flow of the valve. The
irrigation will be by time.
2.3.2 Dosage by Volume Per Area
For those who are used to think about irrigation quantities in terms of volume of
water per a unit of area, the DREAM offers the option of dosing the water by
volume/ area. The units, by which the volume and the area are measured, can be
selected at the DEALERS DEFINITION. The system calculates the amount of water
to be irrigated by multiplying the user’s request with the predefined data of the area
covered by the valve and multiplied by the crop factor in % as explained above.
Notice that :
When irrigating by evaporation there is no planned value to be inserted, and
when working by m3/area the planned value actually contains the planned
amount per area and not the total amount to be irrigated. However, in both
cases, the total amount to be irrigated will appear as a calculated value.

2.4 Local and Central fertilizer dosage
The DREAM 2 recognizes central and local fertilization sites. The central fertilization
enables a number of irrigation lines to share the same fertilizer site, while the local
fertilization is intended to serve individual irrigation lines only. The screens used for
defining the local and the central fertilizers dosage appear next to each other and the
programming of these screens is done in a similar way.
The following dosing options are available:
l/m3 –liters of fertilizer per each cubic meter of water
sec/min –seconds of injection per each minute of irrigation
m:s/m3 –minutes and seconds of injection per each cubic meter of water
l/min –liters of fertilizer per each minute of irrigation
Prop(L) –the specified fertilizer quantity will be injected proportionally
Bulk m:s –continuous injection of the fertilizer quantity specified by time units
Bulk(L) –continuous injection of the fertilizer quantity specified in liters.
Locate the cursor at the dosage mode field next to the desired fertilizer number.
Select the desired dosage mode either by using function key No. 2 for selecting the
default mode, or by using function key No. 3 for opening all the dosing options.
Define the desired fertilizer quantity or desired proportion.
Notice that :
The values displayed at the column of the left dosage depend on the selected
dosage mode: in case of proportional dosage it will show the actual
proportion, in case of bulk dosage it will show the left quantity.
The DREAM 2 offers the convenience of using a library of predefined
FERTILIZER SETS to be used by irrigation programs. For detailed
explanation see the subject of Fertilizer Sets Library within the
PARAMETERS submenu.
