126 ESP-LXD Controller
Decoder Managed Flow Sensors
Flow sensors are managed with SD-210 sensor decoders attached to
the 2-Wire path. The ESP-LXD controller can support and manage up to
five flow sensors.
Connect Flow Sensors
A
Install the flow sensors into your irrigation piping system.
b b
NOTE: 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 any valve.
B
For flow sensing, a Rain Bird SD-210 sensor decoder should be
used in a valve box with proximity to a grounding device, the
2-Wire path and the flow sensor.
b b
NOTE: If a grounding device is not present, install one, ensuring
compliance to all local codes.
C
Follow the field decoder installation process to splice the two
blue wires from the flow sensor to the red and black wires in the
two wire path, completing the splice with approved direct burial
splice kits.
D
Attach the green and yellow wires from the sensor decoder to the
grounding device.
E
Splice the red and black wires from the SD-210 sensor decoder
to the flow sensor. Be sure to follow all instructions included with
the flow sensor. Complete the splices with approved direct burial
splice kits.
F
Carefully peel the sensor decoder barcode label off of the
sensor decoder and affix it into the flow sensor section of the
Programming Guide.
Decoder Managed Weather Sensors
In addition to five flow sensors, ESP-LXD can also support three decoder-
managed weather sensors. Rain Bird SD-210 sensor decoders are used
and installed in exactly the same way. To install decoder-managed
weather sensors, repeat this process but connecting the SD-210 sensor
decoder to the weather sensor instead of to a flow sensor.
