6 LCX 810 Installation Guide
Controller Dimensions and Weight
Each LCX 810 is 11.75 × 8.9 × 2.75 in. and weighs 5 lbs.
Power Requirements
Caution
The LCX 810 should receive power from its own independent,
unswitched circuit.
The LCX 810 operates on a power supply of 24 VAC +/– 20% 50/60 Hz.
The LCX 810 consumes 18 VA of power.
Cabl e Limitations
The maximum cable length for all buses is 4,000 ft at 19,200 baud (up
to 32 Infinet controllers). You can extend buses beyond 4,000 ft or put
more than 32 Infinet contr ollers on less than 4,00 0 ft by using the
InfiLink 200 amplification module.
Note
You mu s t use s hie ld ed ca bl es f o r Infinet to ensure compliance with the
Class A FCC limits and to provide reliable communications.
Cables that form Infinet are 24-gauge, single-t wis ted-pair , tin ned,
shielded copper wire. Use the following cables1 or their equivalents:
• Brand Rex # H 9002 (single-pair)
• Anixter # 9J2401021 (single-pair plenum cable)
The cable should have a nominal impedance of 100 Ohms and a
nominal velocity of propagation of 78%.
1. You can also use any cables you may already have in place for ACNET or LBU.
LCX 810 Installation Guide 7
Capacitance of Infinet cable should be nominal, below 12.5 pF/ft between conductors and below 22 pF/ft between the conductor connected
to ground and the next conductor.
Lightning Protection
Lightning arresters are required at each point where a bus cable enters
or exits a building. Use the following arrester:
Two pair gas tube arrester, Andover Controls # 01-2100-299
Building Ground Requirements
Warning
Be sure that all Infi nity products from Ando ver Controls Corporation
are grounded to true earth ground. This kind of ground protects the
equipment from transients and other power surges in the area.
We cannot guarantee that the controller system will operate as
documented unless you properly grou nd all control lers .
Warning
Be sure to have your grounds inspected before you begin the
installation process to be sure your municipality follows the National
Electrical Code. M a ny muni ci palitie s do not an d often have
substandard electrical grounds.
An example of a substandard ground is a galvanized steel cold water
pipe. As the pipe corrodes, it does not act as a true ground. The corrosion acts as an insulator, raising the potential of the pipe with respect to
the ground.
When lightning strikes in the area of the ins talla tion, it drastically
changes the potential of the earth. Since properly grounded Andover
Controls units respond to changes in potential more rapidly than poorly
grounded electrical systems, a poorly grounded buildi ng tries to reach
8 LCX 810 Installation Guide
ground through the Andover Controls system. The surge of current can
destroy electronic components on the controller board.
Surges of much lower potential than lightning also impact the reliability
of Andover Controls equipment.
Inspecting the Ground
You can check your ground as follows:
1. Check your ground by first inspecting the building power
distribution panel for earth ground termination. If the ground
termination is any of the following, it is not adequate and must be
corrected:
• Does not exist.
• Is connected to a corroded or galvanized pipe.
• Is connected using a small gauge wire (less than 14 AWG).
2. Be sure your Andover Controls cabinet is connected to the ground
with a copper conductor that terminates at the distribution panel.
Environmental Requirements
The LCX 810 operates in rooms with temperatures ranging from 32 to
120°F and with humidity between 10 and 95%, non-condensing.
The controller must be in an Underwriter Laboratories listed enclosure.
Output Equipment Requirements
The eight outputs on the LCX 810 are Form C and provide direct digital
control for digital devices.
In addition to standard ON/OFF, digital outputs have pulse width modulation (PWM). PWM allows you to modulate valves and dampers to
0.1 sec resolution.
LCX 810 Installation Guide 9
All outputs are programmable. Eight override slide switches let you
either manually control each output or set it to A or AUTO so the controller can control it.
The Form C relay of each output is rated for 5 A at 50 VAC.
Input Circuit Specifications
Caution
Andover Controls inputs are designed to be used with two-wire devices
and do not provide sufficient power to operate sensors or transducers
requiring an external power supply.
The following specifications apply to the eight LCX 810 inp uts:
• Voltage Range—0 to 10.000 V
• Resolution—0.0025 V
• Accuracy—+/–0.005 V
• Maximum Pulse Frequency—5 Hz at a duty cycle of 50% with a
minimum pulse width of 100 ms
• Input Impedance—30.1KΩ referenced to 10.000 V
or 10 MΩ referenced to ground with the input reference resistor
switch set to OUT
• Filtering—Corner Frequency at 16 Hz –20 db/decade
• Over-Voltage Protection—120 VAC RMS or 120 VDC indefinitely
on any single channel; +/–1500 V transient for 50 µs on all channels
• Calibration—Per manent (f actory)
Special Factors for Thermistors
To keep thermistor errors minimal, lay out your site so you can limit the
length of wire runs to the maximum for the gauge wire you select.
10 LCX 810 Installation Guide
Table 1 shows the maximum runs for wires of various gauges to keep
errors within .5°F, .25°F, and .10°F when sensing temperatures up to

Connecting the AC Power
Warning
Be sure the AC power cable is not connected to an electrical power
source while you are wiring the controller, or you could receive an
electrical shock that is life-threatening.
Note
If the installation requires the secondary of the 24 V transformer to be
grounded, always connect the "neutral" to ground and only ground it at
the transformer.
The AC power connection is in the upper left corner of the controller.
You must wire the AC cable to the three scre ws on the far le ft .
Caution
Be sure to connect all three wires, HOT, NEUTRAL, and GROUND.
Otherwise, the controller could malfunction.
The three screws are labeled HOT NEU GND. The three wires at the
end of your AC cord are black, white, and green.
1. Place the green wire under the metal plate behind the top screw,
labeled GND.
2. Tighten the screw with a flathead screw driver.
Figure 3 shows the position of the plate, where to place the wire, and
how the screw fits on the plate. You can see how the screw holds
the plate in place once you tighten it.
3. Place the white wire under the metal plate behind the middle screw,
labeled NEU.

Wiring the Infinet to the Infinity CX 9000
You connect the last piece of Infinet cabl ing to the Infinity CX 9000.
See the Andover Controls Infinity CX 9000 Hardware Installation
Guide for instruc tions.
Setting the Input Reference Resistor Switches
The inputs are on the lower left side of the LCX 810. Above the inputs
is a DIP switch, with small switches for each input. Look closely at the
switch and notice that each small switch is numbered. Each small
switch corresponds to the input with the same number.
If an input is either a thermistor or a digital input, switch its input reference resistor switch to IN. If you require that the input be high
impedance (10 MΩ), set its input reference resistor switch to OUT.
Wiring the Inputs
Caution
Do not remotely ground any part of the sensor wiring. Remote grounds
connected to the LCX 810 return terminal could make the co ntroller
operate incorrectly or damage the equipment. The signal return is not
true earth ground. It is an electronic reference point necessary to
interpret the sensor properly. Do not externally ground sensor or switch
terminals that return to the LCX 810.
LCX 810 Installation Guide 19
Caution
Although inputs usually function properly with unshielded sensor wire,
you may need shielded wire if you run the wire as follows:
• In the same conduit with other noise-generating conductors such as
60 Hz AC power.
• In long runs close to large power-consuming or power-generating
equipment that can produce 60 Hz noise.
We recommend you run input wiring in a conduit separate from AC
power or output wiring and avoid long wiring runs.
Caution
Follow the rules below when wiring inputs and outputs:
• Never lay wires across the surface of the printed circuit board. You
should bring input wires in from the left and output wires in from the
right.
• Bundle excess wires toward the back of the cabinet to avoid any
contact with circuit boards.
• Wires should never be within 1 in. of any component on the printed
circuit board.
• Keep cabinet free of foreign materials (extra power supplies, relays,
and so on).
• Be careful when stripping wire not to drop small pieces of wire
inside the cabinet.
If you violate any of these rules, the controller could malfunction.
20 LCX 810 Installation Guide
Caution
Never apply a voltage to a thermistor. Doing so alters the thermistor’s
accuracy and reliability. You should replace a thermistor that has had
voltage applied to it. Never bring a soldering iron to within 3 inches of
the thermistor’s sensing tip.
The inputs are on the lower left side of the LCX 810. Notice that the
inputs are labeled RET, 1, 2, RET, 3, 4, and so on. The first return terminal goes to the first two inputs, the second to the next two inputs, and
so on.
Figure 5 shows a thermistor attached to an input point. One lead
connects to the numbered input terminal, the other to a return terminal.

Follow these steps:
1. Slip the first wire for the first sensor under the input point screw for
input 1 and tighten the screw down on it.
2. Slip the first wire for the second sensor under the input point screw
for input 2 and tighten the screw down on it.
3. Slip the ground wires from both the first and second sensors under
the RETURN screw above input point 1 and tighten the screw down
on them.
4. Repeat the steps 1 through 3 for each pair of inputs.

To account for the input current rising slightly above the maximum
(such as slightly over 20 mA), you should choose a value slightly below
the maximum resistance you calculate. For example, you calculate the
resistance for 0 to 20 mA:

You then select the next standard resistor, 475Ω, with a 0.1% or 1% tolerance. (The accuracy of the input is directly proportional to the
tolerance of the resistor . So the lower the tolerance, the greater the ac-
1
curacy.) The wattage rating should be greater than or equal to watt.

Be sure you check the Andover Controls Infinity CX Programmer’s
Guide for details on how to convert the voltage from a current input to
other units.
Wiring the Outputs
Wiring Form C Outputs
The outputs are along the upper right side of the LCX 810. All
the outputs are Form C and are labeled NC, C, NO from top to bottom.
You wire the outputs as follows:
1. Slip the appropriate wire under the NC screw and tighten the screw
down on it.
2. Slip the appropriate wire under the C screw and tighten the screw
down on it.
3. Slip the appropriate wire under the NO screw and tighten the screw
down on it.
LCX 810 Installation Guide 23
Figure 9 shows the schematic for wiring a Form C output.

expansion modules.
24 LCX 810 Installation Guide
Powering Up the LCX 810
Before you power up the controller, be sure the following are correct:
1. Be sure the battery is connected.
2. Be sure the AC power is wired properly. Check to be sure all three
wires have been connected.
3. Be sure the controller has a true earth ground.
4. Be sure you have used the proper cables and wires and correct
lengths.
5. Be sure you have properly labeled the tag with the name of the
controller before removing it.
6. Be sure the Infinet has been properly wired. Double check that the
ground wire is under the negative screw.
7. Be sure that Infinet cable shields are properly connected.
If you have completed all previous sections in this manual, you are now
ready to power up the controller.
Turn on the AC power source (or close the power connection) and the
controller starts automatically. The following occurs (also occurs when
you press RESET):
1. If the controller has been off, relays remain off. If you have pressed
RESET, relays de-e nergize.
2. If you are pressing RESET, the OVERRIDE light turns on while you
are pressing the button.
3. The CPU light begins flashing and flashes every .2 sec.
4. The TD light immediately starts flashing after you let go of the
button to show data is being transmitted.
5. The RD light begins flashing only if data is being received from
other controllers on the network. This may not happen immediately.
LCX 810 Installation Guide 25
6. If any of the eight outputs is not set to AUTO, the overrides are
enabled and the OVERRIDE light remains steadily on.
7. If the CPU light flashes every .1 sec, it means the CPU has failed a
RAM or ROM test. See the A ndover Controls Inf inet Co ntr oller
Troubleshooting Guide.
8. The EXTERNAL +24V light turns on and remains steadily on.
When the EXTERNAL +24V light goes out, it means no power is
being supplied to the expansion port. You may have to replace the
fuse. See the Andover Controls Infinet Controller Troubleshooting
Guide.
9. The eight status lights on the front of the controller each correspond
to the output with the same number. They remain off until their
corresponding outputs are turned ON by the controller programs. If
no programs are running, the lights remain off. Pulsed outputs flash
on for the duration of the pulse and then go off.
Reset Button
The RESET button is the red square button just left of the horizontal
center of the board at the bottom. You press it to initiate a warm start.
The same events occur for a warm start as for a cold start.
Adjusting the LCD View Angle
The LCD VIEW ANGLE adjustment screw is at the top in the center of
the board. You turn the screw to adjust the angle of the LCD on the
front cabinet.
