ESP-LXIVM Series Controllers
IVM-SEN (Sensor Device)
Flow sensors are connected to the 2-Wire
Path via IVM-SEN 2-Wire devices.
The ESP-LXIVM controller can support up to 5
flow sensors and the LX-IVM Pro controller can
support up to 10 flow sensors.
Connect Flow Sensors
A
Install flow sensors into your irrigation pip-
ing system at each point of connection to
the water supply (water meter or pump).
NOTICE
For optimum performance and flow sensing,
flow sensors should be installed a minimum of
10 pipe diameters in length on the upstream
(supply) side and a least 5 pipe diameters in
length on the downstream (delivery) side before
making any transitions in pipe size/direction or
away from the master valve.
B
Connect the red/white striped wire on the
IVM-SEN to the DC latching solenoid red
wire.
C
Connect the black/white striped wire on
the IVM-SEN to the DC latching solenoid
black wire.
D
Connect the wires from the IVM-SEN to the
flow sensor. Be sure to follow all instruc-
tions included with the flow sensor.
E
For future troubleshooting or modifica-
tions, it is recommended to leave an addi-
tional 3 feet (1 meter) of 2-Wire cable stored
in each valve box location.
NOTICE
Use only WC20 splice kits for all wiring connections to the
2-Wire Path. Improper wiring can cause serious damage to
your controller or irrigation system.

Connect Weather Sensors
In addition to flow sensors, the LX-IVM can also support three
weather sensor connected to the 2-Wire Path via an LX-IVM Sensor
input device. The LX-IVM Pro controller supports seven 2-Wire Path
weather sensors. Weather sensors are connected to the LX-IVM Sen-
sor input in the same way as the flow sensor.
