Rain Bird LX IVM-SEN 2-Wire Sensor Device

Control weather or flow sensors

Flow sensors are connected to the 2-Wire Path via IVM-SEN 2-Wire devices

Features and Benefits

• Field Devices are installed along the 2-Wire path to interface with valves and other hardware.

• Interfaces with LX-IVM to control station valves and master valves

• Rain Bird WC20 connectors (included with IVMSOL; sold separately) to be used for all splices

This product can be used in conjunction with the ESP-LXIVM Series Controllers and its respective ESP-LXIVM 2-Wire Field Devices. These devices (sold separately) include the:

• IVM-SOL: Control station or master valves

• IVM-OUT: Interfaces with LX-IVM to manage 3rd party valves and external gear such as pump stations

• IVM-SEN: Interfaces with LX-IVM to control weather sensors or flow sensors

• IVM-SD: provides surge protection on the 2-Wire path

Product Details

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 Sensor input in the same way as the flow sensor.

Connect Flow Sensors

1. Install flow sensors into your irrigation piping system at each point of connection to the water supply (water meter or pump).

2. Connect the red/white striped wire on the IVM-SEN to the DC latching solenoid red wire.

3. Connect the black/white striped wire on the IVM-SEN to the DC latching solenoid black wire.

4. Connect the wires from the IVM-SEN to the flow sensor. Be sure to follow all instructions included with the flow sensor.

5. For future troubleshooting or modifications, it is recommended to leave an additional 3 feet (1 meter) of 2-Wire cable stored in each valve box location.

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.
