Installation
1. Prepare the installation site as necessary. Rough-in wall switch
boxes and route power supply and LON Network leads as neces sary. Reference Open System Architecture Communication
Network Section for additional information on the communication
network requirements.
2. Assign Network Address as described in the Assigning Switch
Station Network Address Section.
3. With power off, connect power supply leads (FT Version only)
and LON Network leads to the Switch Station as shown in the
Wiring Diagram.
4. Apply power to the system and verify that the Switch Station’s
Power Indicator LED (reference Switch Station Controls Diagram)
is lit.
5. Program Switch Station button controls and lighting system func tionality as described in the Programming Switch Station Functions
Section.

Assigning Switch Station Network Address
The Switch Station network address is set via three rotary dials
located under the Switch Station facia (face cover) as shown in the
Switch Station Controls Diagram. Each Switch Station is factory set
to address 001 prior to shipping. For LX-only networks, each Switch
Station on the network will need to be assigned a unique network
address. Addresses must be assigned in sequential order starting with
address 001. For LonWorks Open System Networks, each Switch
Station on the network should be assigned address 000. This will
place the Switch Station(s) into LonMark compatible mode.
To set the Switch Station Address, carefully remove the Switch Station facia (front cover) to gain access to the address controls. Insert
a small blade screwdriver into the facia catch release as shown in
the Facia Removal Diagram and gently snap it loose at the top edge.
Remove the facia along with any buttons that obscure the three rotary
dials as shown in the Switch Station Controls Diagram. Rotate the
appropriate dial(s) with the small, blade screwdriver till the indicator points to the appropriate number. Assign each Switch Station its
address as delineated in the project plans as applicable. Dial “A” sets
the most signifi cant digit of the network address and Dial “C” sets the
least signifi cant digit of the network address. For example, address
001 is set by Dial A = “0”, Dial B = “0” and Dial C = “1”.

After setting the address, reinstall buttons as necessary, noting proper
orientation of the button light pipe and button LED indicator. Reattach the Switch Station facia.

Programming Switch Station Functions
For LX-only Mode (Address 001-999), refer to the LX Lighting
Controls User’s Manual to assign the Switch Station button(s) to the
lighting circuit(s) and setup schedules and system functionality using
the Touch Tablet Graphical User Interface. For LonMARK Mode
(Address 000), use the LX Switch Station plug-in available from
Hubbell Building Automation, Inc at www.hubbell-automation.com to
assign the Switch Station button(s) to the lighting circuit(s) and setup
schedules and system functionality.
Resetting the Switch Station
If needed, the Switch Station can be reset to an unconfi gured state
or to factory default settings (except network address) by pressing
and holding the Service/Reset button. For LX-only Mode (address
001-999), press and hold the Service/Reset button for 3 seconds. For
LonMARK Mode (address 000), press and hold the Service/Reset button for 20 seconds. Reference Switch Station Controls Diagram.
Replacing Pilot Buttons with Solid Buttons
If necessary, remove the Switch Station facia as described above.
Select and remove the appropriate buttons as described in the project
plans or as desired. Install solid buttons (provided with the Switch
Station) on the momentary switches as shown in the Switch Station
Controls Diagram. Reattach the Switch Station facia.
LX Communications Network
The LX network is a 2-wire communication network. It can operate using any topology (layout) or combination of topologies including Star
and T-confi gurations.
Network cable shall be Belden 8471 or approved equal. Contact HBA for alternate cable types. Maximum total wire length per network
segment (without requiring the use of the lLX Router/Repeater Module, p/n LXRRM) shall not exceed 1500 feet. Up to 56 devices can be
supported per segment.
NOTE: Do not use shielded cable.
Innovative, Integrated and Simple.
