to interrupt the system for a prescribed period of time set
by the interrupt delay position on the dial.
The system startup delay and interrupt period can be
adjusted by moving the dials on the Flow-Clik Interface Box
to the desired settings. The system startup delay allows
for system stabilization to occur prior to the Flow-Clik
sensing for an overflow condition. The startup delay can be
adjusted from 0 to 300 seconds.
The interrupt period setting allows the user to program the
Flow-Clik to shut the system off for a prescribed amount of
time. The interrupt period can be adjusted by moving the
dial to a specified setting from 5 to 60 minutes. There is
also a Restart Manually position on the dial that shuts the
system off until it is manually restarted at the Interface Box.
In the following example, the startup delay is set for 20
seconds and the interrupt period is set to 10 minutes.
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 the controller to continue to irrigate
as it normally would.
