To remove a two-wire device, you must physically diconnect it from thetwo-wire and then perform a Search operation from the device specificmenu. This means a biSensor can only be removed by doing a search fromthe biSensor menu, etc..Each flow device in the system needs to be configured with a K-value and Offset pair, or with apulses/gal value. These numbers are used to take the pulses generated by the flow device andturn them into a more useable value, gallons per minute (or total gallons). These numbers aresupplied by the manufacturer of the flowdevice. If the flow device was purchased fromBaseline, and is either a PFS-series or BHMseriesdevice then these values are preprogrammedinto the device and will be readand set when the Search operation is done. Inthe screen to the right the Pulses/Gal has beenset to 20.0The flow device in this example also has a builtinNormally Open Master Valve (NOMV)decoder. Because this is flow device #1, theNOMV can be used if desired, but is onlyavailable as MV1. This make the paring from flow device #1 to MV1 automaticly. This flowdevice can monitor flow rates and automatically shut down the NOMV on a high flow condition,independent of the state of the controller. To provide 24x7 monitoring, the device must bepowered up and can be either powered externally with a 24 VAC power or by setting the twowireto be always power on. If the two-wire is set to always on, it will only turn off when the dialis moved to the OFF position. Use the CLR key to return to the top menu level from a sub menu.Flow Device Limits & BudgetThere are limits and budgets that can be set bothfor each individual flow device, and for themainline that these flow devices attach to (moreon mainlines in the next section).Turning the dial to the Flow Menu, selecting theFlow Device Limits menu and pressing ENTR willshow the programming screen like the one to theright. There are four values that can be set foreach flow device, with three of these having theoption to shut down watering to some degree ifthe limit is exceeded. These values will now beexplained.Design FlowThis is the specified design flow for the point of connection (POC) that supplies water throughthe flow device to the rest of the irrigation system. This value is one factor when a system isdesigned, and can be used to manage the number of concurrent zones so that the water sourcePage 44Baseline 3200
C h a p t e r 3 – A d v a n c e d P r o g r a m m i n gis used as efficiently as possible. Setting this value to zero will disable its use to control zoneconcurrency.High Flow LimitThis represents a critical limit for the system. When this value is greater than zero, the limit willbe compared against the measured reading from the flow device very minute. If the flow ratereading exceeds the limit for three or four minutes in a row, an alert will be generated. If theshut down box is set to Y (yes), then programs using this POC will be stopped and correspondingMVs will be shut off. If the flow device is a Flow+NOMV type, the flow limit is programmed intothe flow device. Then the high flow limit will be monitored and the NOMV shut off when theflow limit is exceeded – this can still happen with the controller off or powered down as long asthis flow device is powered up (external power required).Unscheduled Flow LimitWhen this limit is set to greater than zero, the flow is monitored 24x7 for any flow that does notcorrespond to running programs. This is often used with a NOMV to allow some flow that is offschedule, allowing for some manual taps or hose bibs. If the flow exceeds the limit for severalminutes then an alert is generated. If the shut down box is Y, then the associated MVs will turnoff.Monthly BudgetWhen this value is greater than zero it performs a policing function for the total water used in asingle month. If the monthly water used exceeds this number then an alert is generated. If theShut Down box is set to Y, then the associated MVs and shut off and water is stopped until thefirst of the next monthMainline LimitsThe next set of limits is set in the Mainline Setupmenu. This screen is reached by turning the dialto the Flow Menu position, highlighting theMainline Setup menu item and pressing ENTR. Ifyou are already in a flow sub-menu, press CLR toreturn to the top level, select the new menuitem and press ENTR.Most sites are served with a single mainline,meaning that all water is distributed through asingle pipe, even though there may be multiplePOCs that supply water to that pipe or mainline.Most programming, therefore, deals withmainline 1, which is the default for all flow devices, master valves, and programs. The settingsfor this screen will be explained:Valid Flow DelayThis time represents the time that it takes to achieve a steady flow rate after a valve change.This needs to take into consideration the valve open and close times (some zones turning on andothers turning off) and possible pipe fill times. The default value is 2 minutes, but may bechanged from 1 to 30 minutes. Zone changes are made at the top of the minute – after changes,Page 45Baseline 3200
