Set Flowatch; Flowatch™ Set Up - Rain Bird ESP-LXIVM Series Installation, Programming & Operation Manual

Set FloWatch™

FloWatch unleashes the true power of the ESP-LXIVM controller.
FloWatch compares current flow conditions to expected, learned or
user-entered flow rates and takes various actions based on your set-
tings and input. Since current flow conditions are required, FloWatch
can only be used when flow sensors are present. To use FloWatch,
you must do all of the following:
Install flow monitoring hardware into the appropriate locations
1.
of your irrigation system. You should install one flow sensor
just downstream of each master valve but upstream of any sta-
tion valves. To ensure stable readings, flow sensors should be
installed at least ten times the distance of the pipe diameter
downstream of the Master Valve with an additional five pipe
diameter distance between the flow sensor and any additional
hardware.
Connect each flow meter to an LX-IVM-Sensor Device. For more
2.
details, see the ESP-LXIVM Field Device Installation Guide that
came with the controller.
Set up the flow sensors using the flow sensor setup. See "Flow
3.
Sensors" on page 31 for more details.
4. Follow the directions below to set up FloWatch.

NOTE: Once you have set up FloWatch on the controller, the cur-
rent flow rate will be shown on the Auto screen unless you turn
off FloWatch. For more information on turning FloWatch on and
off, see "Setting Up and Using flow" below.
84 ESP-LXIVM Series Controllers
FloWatch™ Set Up
The ESP-LXIVM controller lets you set the flow rates you expect or to
automatically Learn Flow rates based on real usage.
Once flow is learned or manually entered, the High Flow and Low
Flow settings let you define the parameters for excessive or low flow
and to set the behavior of the controller when these conditions are
detected. You can also turn FloWatch off or back on again if you like.
FloWatch needs expected flow rates to work properly. Flow rates
can be entered manually or can be learned automatically through
a Learn Flow process. An automatic Learn Flow operation will Learn
Flow for each station that has programmed Run Times. Ensure you
have set up runtimes for all stations included in a Learn Flow exer-
cise prior to setting up a Learn Flow.
B
NOTE: Prior to learning or manually setting station flow rates, it
is a good idea to check the Master Valve assignments for each
of your stations. See "Station Setup" on page 28 for more
details.
NOTICE
Water pressure, particularly from municipal sources, can vary
significantly throughout the day. To mitigate this variance,
press the time delay option to delay the Learn Flow start time
to when irrigation would normally operate.
