over a LONWORKS ® network. All controllers can be completely configured and commissioned through the operator
interface.
The LCI2 fully integrates the HVAC iWorX® system. The LCI2 enables an administrator to add and configure devices
on the iWorX® system and then send the information to the devices over the LONWORKS network. The entire iWorX®
system can be commissioned and modified using the LCI2 touch screen interface.
The LCI2 software runs within a Windows CE.net operating system and is fully upgradable.
Features
• Color touch screen interface for navigation and input
• Self-configuring upon connection to the network
• Configurable user interface options
• View and configure up to 63 controllers
• Administrator and user level access
• Password protection
• Ethernet communications for PC-based configuration

PRECAUTIONS
General
This symbol is intended to alert the user to the presence of important installation and maintenance (servicing) instructions in the literature accompanying the equipment.
WARNING: Electrical shock hazard. Disconnect ALL power sources when installing or servicing this
equipment to prevent electrical shock or equipment damage.
Make all wiring connections in accordance with these instructions and in accordance with pertinent national and local
electrical codes.
Static Electricity
Static charges produce voltages that can damage this equipment. Follow these static electricity precautions when handling this equipment.
• Work in a static free area.
• Touch a known, securely grounded object to discharge any static charge you may have accumulated.
• Use a wrist strap when handling printed circuit boards. The wrist strap must be secured to earth ground.
Location
Avoid locations where corrosive fumes, excessive moisture, vibration or explosive vapors are present.
Avoid electrical noise interference. Do not install near large contactors, electrical machinery, or welding equipment.
This equipment is intended for indoor use only. Operate where ambient temperatures do not exceed 113 °F (45 °C) or
fall below 32 °F (0 °C) and relative humidity does not exceed 80%, non-condensing.
FCC Compliance
This equipment has been tested and found to comply with Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference. This equipment can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and the receiver.
• Connect the equipment to a power source different from that to which the receiver is connected.
• Consult the equipment supplier or an experienced radio/TV technician for help.
You are cautioned that any changes or modifications to this equipment not expressly approved in these instructions
could void your authority to operate this equipment in the United States.

BEFORE INSTALLING
About this Document
The instructions in this document are for the LCI2 module which provides interfacing and scheduling of HVAC.
Inspecting the Equipment
Inspect the shipping carton for damage. If damaged, notify the carrier immediately. Inspect the equipment for damage.
Return damaged equipment to the supplier.
What is Not Included with this Equipment
• A power source for the equipment electronics and peripheral devices.
• Tools necessary to install, troubleshoot and service the equipment.
• The screws needed to mount the device.
• Peripheral devices, such as sensors, actuators, etc.
• Cabling, cabling raceway, and fittings necessary to connect this equipment to the power source, FTT-10A network
and peripheral devices.
Equipment Location
Abide by all warnings regarding equipment location provided earlier in this document.
The equipment should be installed in a secure area like an office or lockable closet.
The LCI2 should be mounted where all operators can easily access it and should not under any circumstances be
mounted outside. The LCI2 should not be mounted where it is subjected to excessive heat, moisture, corrosive or hazardous materials. To ensure that operators of all sizes can easily access the LCI2, mounting should be approximately 4
feet (1.2 meters) from the floor. Note that product mounting may be subject to local and national persons with disabilities acts.
Selecting a Power Source
This equipment requires a UL recognized external Class 2 power source (not supplied) to operate. The LCI2 power
input requires a voltage of 28 to 36 volts DC or 24 volts AC.
INSTALLATION
Warning: Electrical shock hazard. To prevent electrical shock or equipment damage, disconnect ALL
power sources to controllers and loads before installing or servicing this equipment or modifying any wiring.
Mounting the Device
The LCI2 can be either 3-point mounted (on a wall) or 4-point mounted (on a panel).
The 3-point method uses M4, 5, 6 or No. 10 or 12 screws. A ramped keyhole slot in the top back center of the unit slips
over a screw head and as the unit is lowered the unit clamps onto the wall creating a seal around the rear aperture.
Then, the two lower fixing holes can be used to spot their fixing positions.
502-002, Effective: November 12, 2010 5

Page 6
iWorX® LCI2
The 4-point method uses 4 off M4 x 16 mm screws with a maximum panel thickness of 10 mm.
Figure 1: Mounting
DEVICE CONNECTIONS
The LCI2 functions as part of a LONWORKS Network using the integral FTT-10 Free Topology communications transceiver. Connections are on the bottom of the LCI2.
Power
The LCI2 requires class 2 power supply: 24 Vac, 50/60 Hz, or 28 to 36 Vdc. The maximum consumption is 13 VA. Use
a separate power source—do not use a controller’s auxiliary supply output.
NOTE You must ground the LCI2 using a supply earth terminal.

Ethernet (LAN)
The LCI2 uses a standard RJ-45 jack for connection to 10BaseT or 100Base TX (10/100Mb) Ethernet. Plug the LAN
connector into the RJ-45 receptacle on the bottom of the LCI2.

iWorX® LCI2
Network (LON)
The LCI2 requires twisted pair network wire. When connecting the FTT-10A network to connector, connect the twisted
pair to pins NB and NA. These positions are Network B and Network A respectively. Polarity is not an issue since an
FTT-10A network is used for communications.

Grounding the Device
The COM pin must be securely connected to earth ground. Failure to properly ground this equipment may
increase the risk of electrical shock and may increase the possibility of interference to radio/TV reception.
Connecting the device common to earth ground will also connect the power source to earth ground.

TROUBLESHOOTING TIPS
This section provides common problems and remedies for the controller.
Problem Solution
Nothing appears on the LCI2 screen
once it is powered up.
I can’t log on to the LCI2, is there a
default password?
I can’t communicate to any controllers
on the network.
This is most likely related to the input power for the LCI2, ensure the following. A blue LED should be visible on the front of the unit, indicating
that the power is on.
– Is the power source turned on?
– Is the LCI2 powered using 12-24 VDC or 24 VAC?
– Is the power connected to the correct pins?
– Is the contrast adjusted?
The LCI2 has two (2) default passwords, one for the user and one for the
administrator. The default user password is LCI2user and the default
administrator is LCI2. To reset the password, please read the Restore
LCI2 factory defaults section. Be aware that ALL custom settings such as
IP Address will also be reset.
– Ensure that the communications cable is connected to the FTT-10A
connector pins NA & NB.
– Were the service pins on the controllers depressed after the network
was configured?
– Is the FTT-10A Network Resistor Termination Configuration Jumper
set properly?

iWorX® LCI2
Problem Solution
I am not receiving service pings at the
LCI2.
After powering down the LCI2, the
database has been cleared.
The screen seems too sensitive to my
touch or is not sensitive enough for
my touch.
– Ensure that the communications cable is connected to the FTT-10A
connector pins NA & NB.
– Were the service pins on the controllers depressed after the network
was configured?
– Is the FTT-10A Network Resistor Termination Configuration Jumper
set properly?
Check the battery voltage and ensure that it is above 2.7 VDC.
From the main menu you need to select the Utilities: LCI Setup menu
and configure the touch screen. When reconfiguring the screen you need
to apply the pressure that you would normally use when using the LCI2.
