Step-by-Step Guide
Understanding the Flow Stop Jumper Message
The Controller Flow Stop Jumper message indicates that the controller has detected a high flow condition from a sensor input, causing all irrigation to stop immediately.
The message typically displays the following information:
- Controller name and location
- Date and time of the event
- Priority level (High)
- Status: "Flow contact's triggered - all watering has stopped"
- Value: Open
When this message appears, the controller believes there is a high flow situation, and all irrigation will remain stopped until the flow contacts are closed.
Locating the Flow Stop Terminal Jumper
Inside the controller, you'll find the two-wire board. On this board, there is a series of jumper wires, one of which is the flow stop terminal jumper.
🚨This jumper is a critical component for proper flow monitoring functionality.
Common Causes of the Flow Stop Jumper Message
There are several reasons why this message may appear:
Flow sensor connected to terminal
If a flow sensor is physically connected to the flow terminal on the board and detects a high flow situation, this message will trigger. However, it's more common to connect flow sensors to the two-wire path rather than directly to the flow terminal.
Missing jumper lead
The flow jumper lead may be completely missing from the terminal, causing the controller to interpret this as an open flow contact.
Loose jumper lead
The flow jumper lead may be present but not securely fastened, resulting in an intermittent or open connection.
⚠️Note: This issue only applies to flow devices wired directly to the flow terminal on the board. It does not apply to flow devices attached to the two-wire path.
Troubleshooting and Resolution
1. Open the controller cabinet and locate the two-wire board.
2. Identify the flow stop terminal jumper on the board among the series of jumper wires.
3. Inspect the jumper lead connection:
- Check if the jumper lead is present
- Verify that the screw terminal is tight
- Look for any signs of looseness or disconnection
4. If the jumper lead is loose, tighten the screw on the jumper lead to ensure a secure connection.
5. If the jumper lead is missing, replace it with a short piece of 18-gauge wire to restore the proper connection.
6. Once the jumper is properly secured or replaced, the flow contacts will close and irrigation will be able to resume normal operation.
