    Troubleshooting and Clearing a No Flow (NF) Alert

    WeatherTRAK ET Pro2

    PDF es:

    A No Flow alert means that the flow has dropped below the no flow threshold. This can happen when:

    • The solenoid plunger is not lifting to allow the valve to open
    • The master valve is not opening if in use
    • The pump start is not being activated
    • A gate valve or isolation valve in the mainline has been closed


    When this type of alert occurs, the controller will stop irrigation on the station and raise a No Flow alert. It will then move onto the next station in the scheduled sequence. If three consecutive stations have No Flow alerts, the controller stops irrigation.

    Possible Fixes:

    • Bleed the corresponding valve manually to determine if water pressure exists.
    • Verify the Pump Start is operating correctly.
    • Locate and open any closed gate valves.



    To clear a No Flow alert from the controller after troubleshooting:

    1.  Navigate to the ALERTS menu.

    2.  Navigate to view flow status displays.

    3.  Press Select then navigate to the affected station, then * button to clear the alert.
