THEORY OF FUNCTIONTHEORY OF FUNCTION
Irrigation is one of the most important operation in agriculture. With proper
irrigation the quality and quantity of crops can be significantly enhanced.
Correct irrigation is not a simple process: the quantity of water must be sufficient for crops, and if not, photosynthesis and overall growth is impeded.
However, if the amount of water is more than required, plant growth may
become excessive producing a taller, softer and/or damaged product. The
Fertigation Controller can control the quantity of irrigation water based on
time or volume. Different sectors can be irrigated at different times during a
day with different water quantities. In the Fertigation Controller each irrigation
program provides control of pH and of the amount of fertilizer released to the
fields. When necessary, a specific program performs a pH correction by the
introduction of an acid or base into the irrigation water. pH control is based
on sensor input and a specified set point, while fertilizer control is based on
sensor input and setpoint or based on volume measuring. When the Fertigation Controller commands the addition of 1 or multiple fertilizers to the irrigation stream, digital counters continuously monitor the quantity of fertilizer released in the irrigation stream and the overall amount of fertilizer is maintained based on a target prescription. Fertilization can be also controlled
based on conductivity of stream. The Fertigation Controller can command the
addition of multiple (1 to 4) fertilizers to irrigation water. The amount of fertilizer is set by the user for and controlled by a specific program (based on a
prescription). If a pH or conductivity control problem arises, the program
generates an alarm to inform the user. All operations of both control processes are stored in memory and if needed takes the proper action. The Fertigation Controller performs all necessary operations in the monitoring and
control of irrigation and fertilization processes. These operations are conducted continuously throughout the day, month and year. To use and manage
the system properly, all the necessary control values must be set (Setup mode).
During monitoring operations (Consulting mode) the user can obtain information about how the system and irrigation process are functioning, in addition to the history of all operations for current and previous days. To view the
required information on the display or set a specific parameter, the appropriate display panel has to be selected, as explained in this manual.

GENERAL DESCRIPTIONGENERAL DESCRIPTION
The Fertigation Controller is a micro-processor-based system used in fertilization and irrigation control for greenhouses or open fields with powerful, flexible programming features.
The main function of the Fertigation Controller is supplying and controlling
the necessary water and fertilizers for crops according to several parameters
such as acidity, conductivity and ambient temperature.
The user interface is structured in two parts:
1. Consulting (numbered panels indicated by Cxx)
2. Setting (numbered panels indicated by Sxx).
This instruction manual will present the interface in 2 forms:
1. Fertigation Controller functions

In this mode the user has to specify for each program the quantity of each
fertilizer to be dosed. The quantity can be specified in volume or in weight
of active substance. All these settings are made in panel

volume of fertilizer solution in volume of irrigation water. If the volume is
set to N, the weight of active substance is specified together with the concentration of fertilizer solution. The controller will dose then the volume of
fertilizer that contains the specified active substance.

EC and pH control is performed using a proportional controller.
The role of this controller is to maintain a pH and EC value of the irrigation water (see diagram). The control of pH and EC is made separately.
Reagent
A simplified schematic of the process (pH and EC) is presented above.
The components are as follows:
−The mixing tank where input water and additives are combined.
−The additive solution tank containing an acid, base or fertilizer
−The valve for introducing the additive solution into the mixing tank con-
trolled by the proportional controller.
−P(proportional) Controller
−The input water source.
−The irrigation pump used to pump water from the mixing tank to the
irrigation sectors.
The Fertigation controller automatically provides a command output signal to a control element such as a pump or valve based on a sensor input
signal. The function of the proportional controller is to control the dosage
of acid/base or fertilizer in such a way that pH and EC of the process will
have the values close to specified set point. The output signal commands
the opening and closing of a valve through which the additive solution is
10
circulated. The amount of additive solution added is relative to the opening of the valve, which is directly proportional to the magnitude of difference between the “water pool” pH and the set point.
Set point (reference value) is the desired value of the measurement.
Error is define as the difference between set point and measurement:
Error = setpoint – measurementError = setpoint – measurement
Error = setpoint – measurement
Error = setpoint – measurementError = setpoint – measurement
The descriptions and definitions of the individual control actions are as
follows:
Proportional control so called because the controller output is proportional to the magnitude of error. However, proportional control is subject
to one major limitation, steady state offset (steady deviation from the set
point). Increasing the sensitivity of the controller (controller gain) can
reduce the steady state offset but only with slow processes. Because of this
proportional control by itself is used primarily for slow, consistent processes that can tolerate high controller gain (like the control of pH and EC
in irrigation applications), which minimizes steady state offset. Both pH
and EC are controlled by using the same proportional control method.
The proportional control acts on the closing and opening timings of the
motorized valves.
The control cycle used for the pH and EC control can be set by using
panel S60 (SET PROP CTRL). To regulate the aperture of the motorized
valves the proportional control will control the opening and closing times.
These timings are in fact pecentages from the control cycle length.
The sensivity factor simply divides the times used for the actual command
of the motorized valves. It can be used for a fine time of the proportional
control. For each program and for each of the controls (pH or EC) two
parameters define the behavior of thecontroller around a designated setpoint:
- the dead band is the area around the setpoint where the dosage is “in
limits” therefore the actuators need not to change their position.
- the proportional band is the an area around the setpoint where the
proportional control takes place. Outside of these two areas the controller
will open or close the motrized valve with 80% of the control cycle.
