Preamble:Image

 Automation of irrigation systems, be they residential or agricultural, is increasingly becoming
not a "luxury accessory" but an essential component in a modern irrigation system.
The reasons for this road to automation are essentially the same as those that ruled diffusion
of automatic systems in other fields, and even if labour cost reduction is the mainspring
that pushed towards technological innovation, the other automation-related advantages
should not be underestimated.
In fact, it is very short-sighted to think of an automated irrigation system as just a timer that
opens and closes a tap at a set time.
With a central control it is possible to quickly modify the irrigation parameters, change the
duration, the shift and the daily starting time, both on the basis of culture considerations and
through the aid of environmental reading systems (rain sensor, temperature sensor, humidity
sensor, etc. ) which in their turn can be automated.
It must also not be underestimated that an automatic irrigation system, apart from being
cost effective and technically beneficial, responds to an ever growing need that is emerging
on medium to large farms, where the often expert and skilled workers are starting to retire
without equally skilled substitutes being available, and this leaving the economic aspect
aside.
The farming industry is rapidly changing and more and more needs new tools, new technologies
and new professionalism in order to face the challenges of the future.
The ICOD PLUS management system fully meets the requirements in this context.

What is a COD-DECOD system?:


The COD-DECOD (ICOD PLUS) system is an intelligent system that transmits information as well as electrical pulses.This is made possible by the particular structure of the system composed of a data "transmission" station (coder) and of many (as many valves as there are to control) small "reception" stations (decoders).
The coder sends a coded message to the entire connection network and only the decoder able to decode this message is activated.
Therefore, it is no longer necessary to dedicate 1 wire to each valve/station plus the common wire: one cable made up of 2 wires + GND (yellow/green) will be sufficient for the entire system for signal transmission and earthing. Application of the COD-DECOD system brings a considerable advantage for irrigation of vast green areas, such as parks, golf courses, municipal areas, farms, etc. saving on installation time and cost of the electrical cables and labour. A conventional irrigation control system consisting of a control unit and valves is composed of as many wires as there are valves plus, in the best hypothesis, one common wire: for example, if the system is composed of 15 valves, there will be 16 wires leading into the control unit. With the ICOD
PLUS system, there will only be 2 wires + GND (yellow/green) irrespective of the number of stations/valves in the system (max. 48 decoders).As well as not having wiring restrictions, ICOD PLUS allows reaching considerable distances (see the table below).

These distances may vary depending on the type of system installed.
The resin-bonded decoders can activate up to a maximum of 3 solenoids simultaneously.

Solenoids far from the decoder can also be connected. The following table shows the maximum possible distances between the decoder and the solenoid/s.

Versatility and completeness of the ICOD PLUS system:

 

 The number of stations is no longer a determining variable: you can go from 16 to 48 zones simply by adding the expansion modules (8 zones each). This possibility of modular expansion solves any future system enlargement problems.
In addition to the 48 zones, it is also possible to control a master valve and/or a pump control; the latter can be replaced with the alarm relay on ICOD PLUS.
It suffices to install a special decoder (IT-DECODP for the pump control or IT-DECODMV for the master valve) on the system, which will automatically recognise and control it according to instructions without the need to connect the ICOD to the MV terminal of the chosen control unit.
The MV and C/P parameter is already set and enabled on ICOD PLUS; never disable it even if MV and C/P are not used.
Another advantage of this system is that it allows wiring without restrictions: no particular configuration is required (e.g. in a loop* as required for the earlier systems); a branch can be added starting from any point in the system.
This feature is very important for possible future expansion of the system.
It should however be underlined that where systems with many branches have been installed, it might be necessary to terminate the line.
In this case, please contact our Technical Service Department.
ICOD PLUS can be set to medium or low impedance by means of the switch on the board (see the instructions below for use of this device).

It is possible to have:
- 4 decoders per zone

Image

 

- 3 valves per decoder

Image There is also a sensor input (N.C.), an alarm output (N.C.-C-N.O.) and an RS232 port for connection to a PC
(see the image on the side).
Thanks to dedicated software ICOD PLUS can be controlled directly from the PC.
With the software version 2.20, you can modify some operating parameters, also directly from the ICOD keypad:
the time between two activations, the holding current, the pulse width, the pulse voltage, the maximum current, the delay between the master valve and the other valves, the delay between the valves, and set the irrigation time in minutes from a minimum of 1 minute to a maximum of 240 minutes for each station.
The decoders, irrespective of how many are installed, are automatically recognised by ICOD PLUS through a simple search operation. This allows considerable time saving and reduces the possibility of typing errors.
If all the decoders are not automatically recognised, it is always possible to activate the manual mode (see "manual entry of
decoder serial numbers").
If adding a decoder at a later stage, manual entry of the identification code (6-digit alphanumeric number) is the fastest way.
Programming is done via the 6 keys on ICOD, which refer to only 3 parameters (Station, Valve, Cursor) and is displayed on a 16 x 2 alphanumeric display.
For more intuitive display, you can select the desired language from Italian, English (default), French, Spanish, German.  Thanks to the alarms (short-circuit, open-circuit, overload, generic),
you can not only diagnose the fault but also identify the zone in which it occurred.
To facilitate locating a short-circuit, a small self-resetting electronic fuse has been incorporated in each decoder.
Should an alarm occur, these fuses (also in the event of a short-circuit) lock the station involved for the entire irrigation time set and programming will continue as set.
ICOD keeps in memory any alarms recorded during the irrigation phase, and they can be viewed by pressing the "Cursor" key. Image

  Compatibility of the ICOD PLUS system:

ICOD PLUS is compatible with all the Irritrol control units and with any other irrigation control unit, provided that they do not have the open-circuit control function (e.g. Rain Dial Plus) and have a maximum output voltage of 24VAC and a minimum of 15VAC or a maximum of 24VDC and a minimum of 18 VDC. You can thus choose the one most suited to your needs, ignoring what is "downstream": irrespective of the control unit used, the system will always have 2 wires + GND unpolarised.
With a small modification, also the programmers with open-circuit control can be connected to ICOD PLUS (for instructions in this regard, please call the Irritrol Engineering Department).
The system can function with a minimum of one module (8 inputs) up to a maximum of six modules (48 inputs) that can be replaced in the event of a fault or added if you wish to expand the system.
