A no flow alert means that the flow has dropped below the No Flow Threshold.

Possible Causes:

• 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
