The Unscheduled Flow procedure is given in the Controller
Setup section of Chapter 4. The default limit is 200 GPM.
Enabling and Disabling Flow Limit Checking
Once the station limits have been established, the flow limit
checking (upper and lower limits) may be enabled or disabled.
When upper limits have been enabled, all station upper limits as
well as the monthly water limit will be validated. When lower
limits have been enabled, all station lower limits will be
validated on an individual station basis. See Chapter 4 for the
steps to enable or disable station flow limit checking.
The default setting for limit checking is DISABLED for all
stations.
When they are disabled, no limit checking is performed.
However, the GPM flow and total monthly flow readings are
unaffected.
Delaying Flow Rate Limit Checking
Due to drainage of water lines, the initial flow rate for a station
may be much higher than the station steady state condition. To
prevent erroneous station fault detections, the controller delays a
period of time after a station is turned on before making flow
rate limit checks. This delay may be set from 1 to 6 minutes.
The system default for delay of limit checking is two (2)
minutes.
To establish the proper delay, monitor the GPM flow rate for
each station in the irrigation program (s).
See Chapter 7 for details on monitoring GPM rates.
