Navigate to Delay Between Valves (seconds) and use
+/-
to adjust the number of seconds to
wait after a valve closes before the next opens.
Detecting Mainline Breaks
The Mainline Break feature monitors the system for catastrophic mainline breaks. If the flow rate of the
mainline goes beyond the specified value, irrigation will shut off and an alert will be generated. Each
mainline has its own mainline break levels and there are three distinct values. The During Irrigation
value is used whenever scheduled or manual irrigation is running. This is generally the highest of the
values and should be set above the combined flow rate of any stations that irrigate at the same time.
The Master Valve Override value monitors for breaks during a scheduled or manual Master Valve
Override. Finally, the All Other Times is used when not irrigating.
Note:
This menu item only displays if there is a flow meter in use.
To set the mainline break values for each mainline (Figure 51):
1.
From Main Menu, navigate to
Mainlines
and select
Mainline Break
. The Mainline Break screen
displays.
2.
Navigate to the desired Mainline.
3.
For During Irrigation, use
+/-
to assign maximum flow rate during scheduled or manual
irrigation.
4.
For During Master Valve Override, use
+/-
to set the trip point during a scheduled or manual
master valve override.
5.
For All Other Times, use
+/-
to adjust the flow rate for any time irrigation is not running.
Detecting Leaks
The Flow Checking feature monitors the real-time flow rate and compares it to the expected flow rate to
detect leaks or clogged heads. This is also known as head-pop protection.
