Flow alerts are viewed and cleared in the Alerts menu while at the controller or from WeatherTRAK Central.

Viewing flow alerts from the controller:

1.  To view flow alerts, press  ALERTS.

2.   Press à  until VIEW FLOW STATUS displays.

3.  Press SELECT to view any station flow, mainline break, high flow, no flow, leak, or extended leak alert. 

If you have an alert, you will see a two-letter abbreviation (MB, HF, NF, LK, EX).  A double dash (--) means that there is not an alert for the station you are viewing.

Viewing flow alerts from WeatherTRAK Central: 

1.  Hover over the Alerts tab and select Alert List.  A list of all active alerts will display.

Flow Alerts: Types and Definitions

WeatherTRAK controllers can continuously monitor for the following flow conditions:

• MB (Mainline Break)
  A Mainline Break alert generally means a mainline pipe or fitting has failed.
  
  
• HF (Station High Flow)
  A station High Flow alert happens when a sprinkler head or lateral pipe is broken, or the station high flow threshold (SHFT) is too low.
  
  
• NF (No Flow)
  A No Flow alert happens when an operating station is not recording any flow.
  
  
• LK (Leak Detect)
  A Leak Detect alert happens when the flow is observed during non-scheduled irrigation or during scheduled irrigation when no irrigation is operating.
  
  
• EX (Extended Leak Detect)
  An Extended Leak Detect is when a flow meter detects a leak that exceeds a user-defined delay period with a normally open master as part of the irrigation program.

Mainline Break (MB) Alert

If a mainline break has occurred, the flow has exceeded the mainline break threshold and the controller will close the station valves. This can happen when the mainline pipe or fitting has failed.

Possible Fixes:

• Locate and fix the break
• Locate and replace the broken fitting

Station High Flow (HF) Alert

If a station High Flow has occurred, the flow has exceeded the station high flow threshold. The controller stops irrigation on the station that was irrigating and raises the alert. It will then move on to the next station in the scheduled sequence. This can happen when a sprinkler head or lateral pipe is broken.

Possible Fixes:

• Locate and replace the broken sprinkler heads.
• Repair the broken lateral pipe.
• Confirm the station high flow setting is correct.

No Flow (NF) Alert 

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 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

Extended Leak (EX) Alert 

An extended leak occurs when the flow has exceeded the leak detect threshold continuously for the extended leak period. This can happen when:

• A quick coupler or hose bib is being used
• A valve is stuck open
• A mainline fitting is broken
  
  

When this type of alert occurs, the controller closes a normally open master valve and raises an extended leak alert. The next irrigation will start as scheduled, but the alert will not be cleared automatically.

Possible Fixes:

• Repair any valves, quick couplers, or hose bibs.
• Prevent the unauthorized use of a quick coupler or hose bib.

Leak Alert (LK) 

A Leak alert occurs when the flow has exceeded the Leak Detect Threshold for the first leak delay period. This can happen when:

• A quick coupler or hose bib is being used
• A valve is not closing completely and is leaking
• A mainline fitting has a crack and is leaking
• A mainline pipe has developed a slow leak
• A quick coupler is stuck partially open or a hose bib has been left open

This type of alert is for informational purposes. No action will be taken on the controller.

 Possible Fixes:

• Repair any valves, quick couplers, or hose bibs.
• Prevent the unauthorized use of a quick coupler of hose bib.
  
  

To Clear Flow Alerts From the Controller After Troubleshooting:
