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.

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

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.

Program State - During the lifetime of a program it cycles through several

Program StateProgram State

states. Each program is initially in NO SET state which means no settings have been applied to the program by the user. Once the settings have been applied the program is considered in SET state. Once a specific condition such as start time is met the program passes to READY state to await execution. Once the program reaches the highest priority and the start time is met, the program passes to ACTIVE state and executes. The program may be suspended and placed in WAIT state due to a higher priority program moving to ACTIVE state or a specific alarm condition triggering. When a program completes execution it is placed in FINISHED state. The cycle may be repeated and the program returned to ready state if the program repeats were specified after a set delay period.

L / impulseL / impulse

How to set the flow parameter: The total quantity of water is known if we use a counter on the main pipe, this quantity of water must be divided among the opened sectors. We must bear in mind that the pipes might not be the same therefore the controller needs information about the section of pipes. This information is offered by the Flow parameter. These values must be set correctly for the statistics and the volume control to work correctly.

1. First step is to find the diameter for the pipes that guide the water to the sectors.

2. Second step is to find the sector that has the pipe with the maximum diameter. For that sector we set the flow parameter to 100.

3. The next step is to compute the flow for the sectors using the formula: where:

- dmax is the maximum diameter used for the sector pipe

- dsect is the diameter of the sector pipe for the current sector

- Flow sect is the sector for which we set the flow

EXAMPLE:

1. For instance let us consider that the installation has these diameters for the pipes that bring water to the sectors: 1 inch, 1.5 inch and 2 inch. This is equivalent to the first step where the pipes are measured.

2. The pipe with the maximum diameter is the 2 inch pipe, for that pipe we set the flow parameter to 100.

3. Compute the next Flows:

3.1. for the sectors with 1 inch pipe:

3.2. for the sectors with 1.5 inch pipe:

3.3 for all the sectors with a 2 inch pipe the flow is set to 100

NOTE: we consider the diameter of the sector pipe the internal

diameter of the pipe from the main pipe to the sector’s valve, or the minimum section that appears on that pipe. NOTE: if the pipes are clogged up the correct computing of the quantity of water might be impeded!

SENSOR CALIBRASENSOR CALIBRA

SENSOR CALIBRA

SENSOR CALIBRASENSOR CALIBRA

The purpose of calibrating the Sensor’s used in conjunction with the Fertigation Controller is to compensate and adjust the output of the sensors to align with the software of the controller. As time passes the sensors change output slightly due to wear and age making calibration necessary for optimum performance. Monitoring probe performance with known standards and buffers easily identifies the need for calibration. The calibration procedure is performed using panel analog sensor is assigned a channel number which is the index for panel. For each sensor chosen for calibration two measurements with two different known standards are used (e.g. pH 7.01 and pH 4.01 buffer used for pH sensor calibration). For each of the 2 stages of calibration, the calibration panel displays the actual reading and a reference input. The buffer value is entered in the reference input. Prior to calibration of pH and EC rinse the sensor in pure water to ensure a clean probe and avoid cross contamination. Place the sensor in the first standard or buffer and wait for stabilization. Once the reading is stable press

2. Rinse again and place the electrode in the second standard, wait for stabilization and then press panel will display “done”. For best results the calibration buffers (standards) should be considerably different (e.g. pH 7.01 and pH 4.01 buffer) but not excessively close to the limits of the sensor range. After the calibration is complete (both calibration stages complete) rinse and reinsert the probe into the 2 standards to ensure accuracy of calibration. If the probe does not read correctly this may indicate that the same solution (or nearly the same) was used in both stages of calibration or improper values were supplied as a reference or the probe is malfunctioning. For temperature sensor calibration the following items are needed: a reference thermometer, a water and ice mixture, hot water (50°C). For the first calibration step fully immerse the tip of

ALARMS DESCRIPTIONALARMS DESCRIPTION

ALARMS DESCRIPTION

ALARMS DESCRIPTIONALARMS DESCRIPTION

There are 10 kinds of possible software alarms that may occur during the operation the Fertigation Controller.

1. pH Out of range

This alarm is triggered when the value of the pH sensor is outside of the allowable dead band determined by the specified pH Reference value together with the pH min and pH max offset limits for a period of time specified in time-out. These parameters can be set using panel CONTROL).

2. EC Out of range

This alarm is triggered when the value of the EC sensor is outside of the allowable dead band determined by the specified EC Reference value together with the EC min and EC max offset limits for a period of time specified in time-out. These parameters can be set using panel S38 (EC CONTROL).

3. Dirty filter: n

This alarm indicates that the “n” designated filter requires cleaning. The customizable alarm behavior of the Fertigation Controller allows automatic execution of the corresponding filter cleaning program or only the alarm with continuation of normal function with no execution of a filter-cleaning program. These parameters can be set using panel S45 (FILTERS CTRL), “Clean on alarm” option. NOTE: This option, when set for filter # 1 or filter # 2, applies to BOTH filter-cleaning programs.

4. Low level fert: n

This alarm is triggered if the fertilizer level of the “n” designated tank has reached a minimum value. Once this alarm is triggered, the assigned

S36S36

S36 (PH

S36S36

valve will close and that fertilizer tank will be excluded from use during fertilization control of the irrigation process.

5. Low level acid

This alarm is triggered if the level of the acid (or alkaline) tank has reached a minimum value. Once this alarm is triggered, the assigned valve will close and that tank will be excluded from use during pH control of the irrigation process.

6. No water supply

This alarm is triggered due to an incoming water supply failure event. The water supply problem is considered only if the Water Incoming Presence sensor signals that is no water on a water source that is used by the current irrigation program. The Fertigation Controller is automatically switched to BLOCK state and all irrigation programs are SUSPENDED until this event clears. Once the event is cleared the Fertigation Controller automatically resumes normal operation in the previous state without any external intervention.

7. IRRIGATION COUNTER FAILURE

This alarm is triggered if the main pump is working but no flow is detected trough the main counter. In this situation the controller enters the STOP mode! The maximum time between 2 transition of the main pump is set in panel duration of Max. time. no transition is detected then the controller generates the alarm and enters in STOP mode.

8. OVERDOSE ALARM.

This alarm is triggered when the dosed value is greater than the needed value for the specific amount of water. Of course the amount of fertilizer is set for each program and each fertilizer tank, but there is only one global value that describes the overdose limit (percentage) referred here as the overdose threshold. If the dosed value is greater than the needed value plus a fraction from the needed value defined by the overdose threshold than the overdose alarm is triggered: When the alarm is triggered the user has the option to put the controller into stop state (see panel 53 (STOP ON VOL ALRM)). When entering the stop state the controller will decrease the dosed value to the needed value of fertilizer so the program can be restored manually, this is up to the user, and the user must be aware of the effects of this situation.

9. UNDERDOSE ALARM:

This alarm is similar to the previous one except that it describes the situation when the amount of a specific fertilizer is too low in the

S56S56

S56 (SET FLOW PARAMS): Max. time. If for a

S56S56

irrigation water. NOTE: - the overdose and underdose thresholds are not the same (set from panel 30 VOLUME DOSING ALARMS). Both alarms are triggered if the overdose/underdose alarm trigger condition is TRUE for more than 3 dosing cycles!

10. FERTILIZER WASTE ALARM:

This alarm is triggered if the counter of an fertilizer is changing state (transition), when this should not happen, it means that the fertilizer is flowing when it should not. To trigger this alarm more than 3 transitions for one fertilizer must be detected when the controller is in the following state:

- is already in STOP mode

- no program is running

- the current running program is in pre/post irrigation As it describes a malfunction situation the controller is automatically put in STOP. The user intervention is required!

− THE CONTROLLER DOESN’T FUNCTION Check to insure that the proper voltage is applied to the controller. After connecting the controller to the power supply (wall outlet), the unit should initiate and the Hanna logo should appear on the LCD. If this does not occur you should check the main fuse located next to the power input connections. If changing the fuse does not solve the problem, call a Hanna Instruments Technical Support.

− THE ALARM LED IS ON

• this could be caused by the fact that the fuse of sector relays is burned

and the controller is attempting to open a valve (activate a relay).

• this can indicate that a software alarm has occurred. Check panel

C23 (ALARM) to determine what type of alarm condition is active.

− MIXING TANK EMPTY Check water level in mixing tank. The controller will not function without a proper water level in the mixing tank or a reliable source of water. Check the integrity of the tank and the water supply lines.

− PH SENSOR OUT OF RANGE This indicates that the controller cannot adjust the pH value of the process within the specified range. Check panel

S36S36

S36 (PH CONTROL) to be sure that

S36S36

the settings are correct. Also you should check the pH tank and supply lines for proper level and function. Check the pH level of the incoming water to determine if a change has occurred that may not be correctable by the type and amount of acid (or base) being used. If the problem persists after checking the process pH and acid or base supply, check panel PARAMETERS) to be sure that the control algorithms are correct.

− EC SENSOR OUT OF RANGE This indicates that the controller cannot adjust the EC value of the process within the specified range. Check panel S38 (EC CONTROL) and S39 (SET FERTILIZERS) to be sure the settings are correct. Also you should check the 4 fertilizer tanks and supply lines for proper level and function. Check the EC level of the incoming water to determine if a change has occurred that may not be correctable by the type and amount of fertilizers being used. If the problem persists after checking the process EC and fertilizer supplies, check

S60S60

panel

S60 (SET PID PARAMETERS) to be sure that the control algorithms are

S60S60

correct.

− INCORRECTLY DISPLAYED SENSOR VALUES. Recalibrate sensors.

− OUTPUT VALVE DOESN’T WORK

Check fuses.

− CONTROLLER IN STOP Please see the alarm panel to check the active alarms and remove the cause: here is a list of causes that might put the controller in stop:

-Temporary break: this is a user controlled input that can pause the controller. Is intended for maintenance use

-Conditional stop: this digital input is used to signal to the controller that something is wrong in the installation the user can choose how to use this input, please check the related hardware.

-Overdose, advice: there is too much fertilizer in the water, check the valve of the fertilizer.

-Underdose, advice: same as overdose

-No water supply, advice: check the water level in the mixing tank or the level sensor

-Irrigation counter failure, advice: for this alarm check the counter of the main pipe, the main pipe and the pumps. After checking the alarms and removing the cause put the controller into WORK state. If any of the suggestions above do not work please contact Hanna Instruments Technical Support.
