====== Programs - Fertilizer Programs ======

Below we explain the basic setup of a Fertilizer Program. Should the content not meet your needs, contact your Farmsync Technician for advice & please feel free to request that we update our content to be more relevant.

=====Creating a Fertilizer Program=====

*Should you require assistance in the setup of a new dosing channel added, contact your Farmsync Technician

   * A: Click “Programs” on the Menu Bar
   * B: Click on “Fertilizer Programs”

{{ :programs:menubar2.png?nolink&300  |}}

=====Fertilizer Program Details=====
*Each Fert Channel must have its own Fertilizer Program

====Fertilizer Details====

{{ :programs:fert_details.png?nolink&400|}}

  * A: “Name” – Enter a Name for your program
  * B: “External Reference” – For FARMSYNCTM internal use only
  * C: “Station” – Select the relevant Station from the dropdown list
  * D: “Fertilizer Control Type” – Select the Fertilizer Control Type from the dropdown list 

If the channel is set up according the one of these, it is the only way that the system can dose, the client cannot change methods on a day-to-day basis 

  - Time - Batching (L) by breaking the specified total volume of fertilizer into batches & inject accordingly over the specified time
  - Liters using Tank Level - Batching (L) by using the tank level to determine total volume of Fertilizer that has been injected
  - Liters using Flow Sensor - Batching (L) by using the Flow Sensor to determine the total volume of Fertilizer that has been injected 
  - Proportional & Liters using Flow Sensor - Batching (L) as “Liters using Flow Sensor” but the injection rate is “Capped” to specified L/m3
  - Proportional & Liters using Tank Level - Batching (L) as “Liters using Tank Level” but the injection rate is “Capped” to specified L/m3
  - Setpoint - ????
  - EC with Liters - EC control by injecting Fertilizer at a calculated rate to maintain a specified EC value / Stops after reaching a specified total volume of Fertilizer injected (L)
  - PH - PH control by injecting Fertilizer at a calculated rate to maintain a specified PH value
  - Proportional Flow Sensor - Proportional (L/m3) by using the Mainline Flow rate, Fertilizer Runtime(min) & specified injection rate (L/m3)
  - EC - EC control by injecting Fertilizer at a calculated rate to maintain a specified EC value / Stops after reaching a specified Runtime(min)
 
  * E: “Fertilizer” – Select the relevant Fertilizer from the dropdown list

  * K: “Mainline min Pressure (Bar)” – Enter the min pressure required in the Mainline 
  * N: “Channel Select Port” – Should there be a pump installed between the Storage Tanks & the channels, providing positive pressure on the channel (in cases where the tanks are not installed at a appropriate height), select that pump from the dropdown list





=====Flow Sensor=====
{{ :programs:flow_sensor_settings.png?nolink&400|}}
  * A: “Fertilizer Tank Level Sensor” – Select the relevant Tank Level Sensor from the dropdown list
  * B: “L/Pulse” – Enter the Pulse Rating of the water meter installed
    *  	0:1 = 1L
    *  	0:0.1 = 0.1L
  * C: “Fertilizer Flow Sensor” – Select the relevant Fertilizer water meter sensor from the dropdown list
  * D: “Fertilizer Flow Rate Sensor” – Select the relevant Flow Rate sensor from the dropdown list
    *  	If Flow Rate Sensor is connected to the Controller, an option from the dropdown list may be chosen
    *  	If Flow Rate Sensor is connected to the Expander, select “Not Set” from the dropdown list
  * E: “Calculate Flow from Slave” –
  * F: “Fertigation Rate Flow Sensor” – Select the relevant sensor from the dropdown list
  * G: “Mainline Flow Sensor” – Select the relevant Mainline Flow Sensor from the dropdown list

=====Agitating=====
{{ :programs:agitating.png?nolink&400|}}

A – D settings are for Agitating DURING Fertigation
  * A: “Agitating Duration (sec)” – Enter the duration of Agitation 
  * B: “Agitating Interval (sec)” – Enter the duration of time that must pass before Agitating again

  * C: “Agitate Before Applying” – Tick this box to Agitate before applying Fertigation
  * D: “Agitate While Applying” – Tick this box to Agitate while applying Fertigation *Will agitate the entire time fertigation program is active (leave A & B clear)

  * E: “Agitating Port” – Select the relevant port connected to the Agitator

F – G settings are for Agitating when not Fertigating
  * F: “Auto Agitating Duration (sec)” – Enter the duration of Agitation
  * G: “Auto Agitating Interval (sec)” – Enter the duration of time that must pass before Agitating again
  * H: “Agitation Program” - 

=====EC Control=====
The values entered here for EC min & Max are used for the EC Alarms if the Enable Alarm on EC Critical is active
{{ :programs:ec_control.png?nolink&400|}}

  * A: “EC Min” – Enter the min EC value allowed 
  * B: “EC Target” – Enter the Target EC value
  * C: “EC Max” – Enter the max EC value allowed
  * D: “EC Compensation (%)” – 
  * E: “EC Compensation Adjustment (%)” - 

=====Alarms=====
{{ :programs:fert_alarms.png?nolink&400|}}

====Fertilizer Flow Rate Alarms====
  * A: “Alarm on Low Tank Level” – Tick to enable alarm on Low Tank Level
  * B: “Enable Fertilizer Flow Rate Alarm” – Tick to enable Flow Rate Alarm set on Fertilizer
  * C: “Flow Fertilizer Rate Error (%)” – Enter percentage Flow Rate allowed to be higher than expected before alarm is triggered
    * Note: this percentage is the inverted; meaning if the expected Flow Rate is 100L/h, & Error is set to 80%, the alarm will be triggered on 100L/h + 20% = 120L/h
  * D: “Alarm on EC Error” – Tick this box to enable alarm on EC Error
  * E: “Alarm on PH Error” – Tick this box to enable alarm on PH Error
  * F: “Fertilizer Alarm Duration Threshold (sec)” – The duration of time allowed for the Fertilizer programs values to be higher than margins allow before the alarm is triggered
  * G: “Uncontrolled Alarm Amount (L)” – Max Volume of Fertilizer allowed to pass during one dose before alarm is triggered 
    * This alarm is for when the Fert Valve does not close (overdosing)
    * Or when there is a leak 

====Fertilizer Pump Alarms====
  * H: “Fert Pump Start Delay (sec)” – Enter the pump start delay here 
  * I: “Fert Pump Alarm Sensor” – Select the relevant sensor from the dropdown list 
  * J: “Fert Pump Alarm Min” – Enter the min value allowed for sensor selected
  * K: “Fert Pump Alarm Max” – Enter the max value allowed for sensor selected

=====Output Control=====

    *  	“Pulse Frequency” – 
    *  	“On/Off Delay” – used during proportional dosing, opens & closed the dosing valves based on values entered in C - E

======Adding Fertilizer to Valve Program======

=====Adding a Fertilizer Program to a Step=====
Each “Step” has provision to add Fert Programs.
{{ :programs:fert_to_step.png?nolink&400 |}}

  * A: To add a Fertilizer program to the Valve Program, click on the “+” 

{{ :programs:fert_step_details.png?nolink&400 |}}

  * As seen above, you can now enter the following specifications:
    * "Liters" - if dosing according to a batching method
    * "L/m3" - if dosing according to a proportional method
    * "EC" - if dosing to maintain a certain EC
    * "Pre-Delay" - duration of time that must pass from start of irrigation until fert program starts
    * "Post-Delay" - duration of time that the fert program must stop before the irrigation program stops
