System Overview and Flow-Clik Operation (continued)

High-Flow Scenario 1 – Valve 3 Lateral Line Breaks

If a lateral line break should occur on valve number 3, the Flow-Clik would sense a “high flow” condition and would shut the system down after a sustained 20 second over flow condition. Once the system has been shut off, the Flow-Clik will continue to keep the system off for the 10 minutes programmed into the interrupt period. After 10 minutes have passed, the Flow-Clik will turn the system back on and begin to monitor for an over flow condition.

If the run time for zone 3 is 19 minutes and is scheduled to come on at 6:00 am, then the following chain of events would occur:

6:00 AM – Valve 3 is activated and the Flow-Clik senses an over flow condition. After a 20 second delay the system is shut off for 10 minutes.

6:10 AM – Valve 3 is reactivated (it still has 9 minutes of run time left) and after a 20 second delay, a “high flow” condition is again identified and the system is interrupted for another 10 minutes.

6:18 AM – Valve 4 is scheduled to be activated by the irrigation controller, however, the Flow-Clik continues to interrupt system operation due to the 1 minute left on the interrupt delay.

6:20 AM – Valve 4 is activated and the Flow-Clik begins to monitor the flow of valve 4 which is below the “high flow” trigger point enabling thecontroller to continue to irrigate as it normally would.

Post 6:20 AM – For the balance of the irrigation cycle flow is monitored by the Flow-Clik without exceeding the maximum and the total irrigation schedule is completed.

The Flow-Clik will continue to shut the system off during automatic operation of valve 3 until the lateral line break is repaired.
