ESPLXD-ET Controller
Surge Protection and Grounding
b
c
WARNING:
The ESPLXD-ET controller and the 2-Wire path must
be properly surge protected and grounded. Doing so can help
prevent damage to the controller and irrigation system and also
significantly reduce troubleshooting, repair time and expense.
Failure to do so could result in failure of your controller and
voiding the warranty.
Rain Bird requires the 2-Wire path to be surge protected and grounded
with one LSP every 500 feet or every 8 decoders, whichever is smaller.
Ensure that all grounding devices are compliant with local electrical
codes.
Install Lightning Surge Protectors (LSP-1s)
A
Using a design drawing or as-built diagram for your installation
system, determine the number of LSP-1s required and where they
will need to be installed.
B
At the first LSP-1 location, install a grounding device, typically
a grounding rod or plate, which meets all local codes, near the
2-Wire path.
C
Splice the blue wires from a Rain Bird LSP-1 to the 2-Wire path in
the same manner as the installation of a field decoder detailed
above, completing the splices with an approved direct-bury
splice kit.
D
Connect the ground wires from the LSP-1 to the grounding device
and install the LSP-1 inside a valve box.
E
Repeat this process to install all other LSP-1s as needed, noting
their locations on your as-built diagram and/or design drawings.
b

NOTE:
LSP-1s do not have decoder addresses, so it’s not necessary
to capture this information from your LSP-1s. For this reason, LSP-
1s also do not have peel-off barcode labels for the Programming
Guide. LSP-1s do not need to be recognized by or programmed
into the controller or noted on the Programming Guide.
Decoder Managed Flow Sensors
Flow sensors are managed with SD-210 sensor decoders attached to
the 2-Wire path. The ESPLXD-ET 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.
