Zone Flow
Each zone can have a design flow set manually,
or it can run through a learn flow cycle and have
its “design flow” set automatically. This is useful
after doing work on a zone (head changes) or if a
program learn flow had a zone that failed to be
able to run a single zone or a set of zones
through a learn flow cycle.
Enter this screen from the top menu level of the
Flow Menu dial position. Highlight the Zone Flow
Setup and press the ENTR key. As can be seen on
the screen to the right, each zone can have a
design flow entered. Once a learn flow cycle is completed successfully, the design flow value is
replaced by the learn flow value. Note that the learned flow value is retained so a modification
to the design flow value manually does not totally erase the learned flow value. To start a learn
flow cycle, highlight the Learn Flow Cycle square using the NEXT/PREV keys and then press the +
key to advance the delay time by 15 minutes (this works the same as the delay time for doing a
program learn flow cycle). Advance to the next zone by pressing ENTR.
Multiple Flow Devices and Mainlines
The BaseStation 3200 has the power to manage four mainlines, independent and separate from
each other. A mainline is defined as a primary water delivery pipe that delivers water to a
specific set of zones (valves and heads). Mainlines are different and separate if the water in one
mainline cannot be delivered to the zones of another mainline.
Sites with this topology can be programmed so that each mainline operates independently of
each other. This means that while there is a learn flow cycle on mainline 1, or a high flow
shutdown event on mainline 2, the other mainlines and their programs/zones can continue to
operate normally. To provide this capability, there are assignments that are made between the
pieces of the irrigation system and a mainline. A mainline can have flow devices, master valves,
and programs (which
contain the zones
connected to the
mainline). The simple
diagram to the right
shows how a site that has
two mainlines might be
configured. Note that
mainline 2 has two POCs,
each with a master valve
and flow device. A
specific site diagram is needed and will help the programming process.
