ESPLXD-ET Controller
Install Station Expansion Modules
The ESPLXD-ET controller comes standard with 50 stations available.
This can easily be expanded by adding one or two optional ESP-LXD-
SM75 Station Modules. Each station module adds 75 additional stations
to increase capacity to 125 or 200 stations.
Once your LXD Decoder module
is correctly installed, you’ll notice
that two additional module
slots are still available. Each of
these module slots can accept
one station module. Follow the
instructions to install one or two
station modules. The controller
will automatically recognize the
additional station capacity.

NOTE:
To remove the module again, press in on the (two) release
buttons on either side of the module.
Connect Field Wiring
The ESPLXD-ET controller can support up to four 2-Wire connections.
The controller will manage multiple 2-Wire connections as a single
2-Wire path. The cable must be approved for underground use.
Rain Bird recommends use of MAXI Cable, #14 AWG, as your 2-Wire
communications cable.

WARNING
: You must use special precautions when valve wires
(also known as station or solenoid wires) are located adjacent to or
share a conduit with other wires, such as wires used for landscape
lighting, other “low voltage” systems or other “high voltage”
power. Be sure to separate and insulate all conductors carefully
taking care not to damage wire insulation during installation. An
electrical “short” (contact) between the valve wires and another
source of power can damage the controller and create a fire
hazard.
