Please note that to create a filter program, the following must be created first:

• “Filter” Mainline - created under setup_mainlines
• Valves for each of the backflush valves on the filter station - created under setup_manage valves
• DP (Differential Pressure) sensor - created under setup_all sensors

Should you require help in creating these, please contact your Farmsync Technician

• A: “Name” – Enter a name for the Filter Program
• B: “External Reference” – For Farmsync internal use only
• C: “Station” – Select the relevant station that the filter is connected to from the dropdown list

Press “Save” in order to set the rest of the settings for this program

• A: “Enabled Automatic Start”
  • It is important to note that if this function is ticked, the Flush program will run permanently, meaning even when no Valve program is running
  • If this option is taken, DO NOT add the Filter Flush program to a Valve Program, as this will cause a clash
  • If you want the Filter Flush program to run ONLY when the valve program is running, then this function must NOT be ticked
• B: “Stop Remote Flush program when flushing done” – under construction
• C: “Total Program Run Time (minutes)” – Enter the max Runtime (min) for the flush program
• D: “Flush Duration (seconds)” – Enter the time duration (sec) allowed for each filter to flush
• E: “Flush Time Duration (seconds)” – Enter the time allowed between filters to pass before the next filter flushes
• F: “Minimum duration between flush operations (seconds)” – Enter the min time duration between flush cycles
• G: “Min Pressure to enable pressure flush (Bar)” – Enter the min pressure difference between in & outlet of filter allowed before filter flushes
• H: “Min Pressure to enable time flush (Bar)” – Enter the min pressure the system must supply for flushing to occur (refer to supplier filter specifications)
• I: “Pressure Flush Delay (seconds)” – Enter the time (sec) allowed to pass for pressure difference to be higher than min before flush is enabled
• J: “Flush Duration Delay (seconds)” – enter the duration of time that must past from when flushing is triggered before the flushing valves open (eg. allows time for Mainvalve to close)
• K: “Flush on Start” – When enabled, filter will flush when program starts
• L: “Flush on End” – When enabled, filter will flush when program stops
• M: “Filter Start Delay (seconds)” – Duration of time allowed to pass after filter program has started before filter flushes

See below example of flush program times explained:

• A: “Flush Activated Sensor” –
• B: “Flush Active Port” –
• C: “Before Filter or Differential Pressure Sensor” – Select the relevant Pressure Sensor / DP Sensor from the dropdown list
• D: “After Filter Pressure Sensor” – Select the relevant Pressure Sensor from the dropdown list (if DP Sensor was selected in C, then this sensor can be left to “Not Set”
• E: “Remote Flush Program to Start when Flushing” –
• F: “Remote Pause / Resume program when flushing” – Select the relevant program that must be paused if the flushing sequence is initiated, this program will resume once the flushing program is completed
• G: “Mainline Control Valve” – Select the relevant Mainline Control Valve from the dropdown list, should one be present
• H: “Mainline Control Valve Close Delay” – Enter the duration of time allowed to pass from when filter flush is initiated before the Mainline Control Valve must close
• I: “Master Filter Program” – Select the relevant Filter program from the dropdown list
• J: “Auto Start from Master Filter Program” – Enable if current filter program must start the same time as the Master Filter Program

Choose from the dropdown lists below the relevant Flush Valves that were created for the Filter under “Setup_Manage Valves”; Provision has been made for 32 valves in total.
