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

• “Filter” Mainline
• Valves for each of the backflush valves on the filter station
• DP (Differential Pressure) sensor

There are two scenarios that will be explained below:

1. Creating a Filter Program where flushing is managed by an external flush controller
   1. In this case, Farmsync only sends a start & end command
2. Creating a Filter Program that issues all commands from Farmsync
   1. In this case all the flush times are set on Farmsync

• 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

• 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
