Controller Dimensions and Weight
Each LCX 890 is 34.9H × 18.3W × 4.67D in. (886.46H × 464.82W ×
118.62D mm) and weighs 38 lbs (14.17 kg) without relays.
Each LCX 898 is 38.8H × 27.35W × 4.67D in. (985.52H × 694.69W ×
118.62D mm) and weighs 42 lbs (23.49 kg) without relays.
Power Requirements
Caution
Any LCX 890 should receive power from its own independent,
unswitched circuit.
You can select an AC line voltage of 115 V, 230 V, or 277 V. You receive the controller set to 115 V. Instructions for selecting the AC line
voltage you want are included with the installation.
Voltages you can select are as follows (each uses a 2 A slow blow fuse):
• 115 VAC +/– 10% 50/60 Hz
• 230 VAC +/– 10% 50/60 Hz
• 277 VAC +/– 10% 50/60 Hz
Each LCX 890 series controller consumes 115 VA of power.
Cabl e Limitat ions
The maximum cable length for all buses is 4,000 ft (1219 m) at 19,200
baud (up to 32 Infinet controllers). You can extend buses beyond
4,000 ft (1219 m) or put more than 32 Infinet controllers on less than
4,000 ft (1219 m) by using the InfiLink 200 amplification mo dule.
LCX 890 Installation Guide 3
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 (.22 to .38 mm2), single-twistedpair, tinned, 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 Ω and a nominal ve-
locity of propagati on o f 7 8%.
Capaci tanc e of In fi net c able s houl d be n omi nal, b el ow 12.5 pF/ ft (41 pF/
m) between conductors an d below 22 pF/ft (72 pF/m) between the conductor c onnected to ground and the next cond uc tor.
Lightning Protection
The LCX 898 has a 2 A, 500 V fuse and 1500 V transformer that isolates
the unit.
The unit has 1500 V .01 µF spark gap caps from HOT and NEUTRAL
to chassis ground. These help increase protection against power surges.
Lightning arrestors are required at each point where a bus cable enters
or exits a building. Use the following arrestor:
Two pair gas tube arrestor, Andover Controls # 01-2100-299.
1. You can also use any cables you may already have in place for ACNET or LBUS.

Building Ground Requirements
Warning
Be sure that all hardware from Andover Controls Corporati on is
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. Many mu nicipalities do not and 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
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.
LCX 890 Installation Guide 5
Inspecting the Ground
You can check your ground as follows:
1. Check yo ur ground by firs t inspecti ng the buildi ng power distributi on
panel fo r ea rth ground t er mination. If t he ground termina t ion is any
of the f ollowing, it is not adequa te an d must be cor rec ted:
• Does not exist.
• Is connected to a corroded or galvanized pipe.
• Is connected using a small gauge wire (less than 14 AWG
or 2.5 mm2).
2. Be sure your Andover Controls cabinet is connected to the ground
with a copper conductor that terminates at the distribution panel.
Environmental Requirements
All LCX 890 con trollers operate in rooms with temperatures rangin g
from 32 to 120°F and with humidity between 10 and 95%, noncondensing. If you connect a SmartSensor, the temperature can range from 32
to 104°F.
The controller is in an Underwriter Laborator ies approved enclosu re.
Do not remove the controller from the enclosure provided.
Output Requirements
The outputs on LCX 890 and 898 controllers are digital and can be
wired to control lighting. To each output you attach either relays that
give status feedback (Andover Controls Part # 01-0100-300) or relay s
that do not give status feedback (Andover Controls Part # 01-0 100-
299).
All outputs are programmable. You may also wire a momentary switch
to the light. This switch can be a motion detector or other occupancy
sensor. When the motion detector or other sensor determines light is required, it sends a signal to the output relay. The relay mechanically
6 LCX 890 Installation Guide
latches itself ON. The relay remains ON until you either set it to OFF
from the software or the momentary switch sets it to off .
The status of the li ght is avai lable in the softwar e if you use rel ays th at
give feedback. In addition, the status light adjacent to each output lights
up if the output is ON.
Each relay is rated for any of the fol lowing lighting loads:
Note
Andover Controls does not recommend switching DC loads. Switching
DC loads can damage the relay.
• 20 A with a Tungsten filament at 125 VAC
• 20 A with a Ballast at 277 VAC
• 20 A with Resistive element at 277 VAC
The motor load is 1/2 horsepower at 110 to 125 VAC or 1/2 horsepower
at 220 to 227 VAC.
Andover Controls relays are prewired for the LCX 890 series of controllers and plug in to the 5-pin connector adjacent to each output.
LCX 898 outputs have 4,000 V noise immunity from IEC E801- 4 and
ANSI/IEEE C 62.41 5 ns/50 ns EFT test waveforms.
Input Requirements
Caution
Andover Controls inputs are designed to be used with two-wire devices
and do not provide sufficient power to operate sensors requiring an
external power supply.
The LCX 890 controllers each have two types of inputs, digital and uni-
versal. The paragraphs that follow give the requirements of each type of
input.
LCX 890 Installation Guide 7
Digital Inputs
The first 16 inputs on all LCX 890 controllers are digital, for switc hes .
The controller can read the settings of these switches.
All digital inputs have an input impedance of 220KΩ referenced to
5.000 V.
Universal Inputs
The las t eight in puts (not inc luding the E M X 170 port) on the LCX 890
or LCX 898 (17 through 24) are uni versal. T he last ei ght inpu ts on the are
univer sal. Universa l inputs are fo r any type of sens or, such as the rmistors,
motion sensors, and switches.
Below are the requirements of each universal input:
• Voltage Range—0 to 5.115 V
• Resolution—0.005 V
• Accuracy—+/–0.015 V
• Maximum Pulse Frequency—5 Hz at a duty cycle of 50% with a
minimum pulse width of 100 ms
• Input Impedance—10K Ω referenced to 5.120 V
• Filtering—Corner Frequency at 15 Hz, –20 db/decade
• Over-Voltage Protection—24 VAC RMS or 24 VDC indefinitely on
any single channel; +/–1500 V transient for 50 µs on all channels
• Calibration—Per manent (f actory)
EMX 170 Inputs
If you ha ve a n EMX 1 70 on the EMX 170 p ort, it is an additional input,
numb ered 25.

Special Factors for Thermistors
You could connect a thermistor to one of the analog inputs. 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.
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
70°F.

Laying Out the Site Setup
You may want to draw a map of where you plan to put each controller
and store it in a notebook.
Find the tag attached to each controller that gives the number of the controller. Bef ore you remove any tags, be sure the tag has all of the
following information on it:
• Location of the controller.
• Serial number.
• Model name and number.
• Communications port the Infinet connects to on the 9000 controller.
Then collect the tags. You will need to know where your controllers are
located when you later assign a name to each controller and each input
and output.

Finding the Connection Ports on the LCX 890
Figure 3 shows inside the LCX 890 cabinet. The LCX 890 has a vertical
metal divider about two-thirds across the cabinet that extends from the
top of the cabinet to the bottom.
On the left side of the divider are two distinct parts—the upper part,
where the terminal wiring board is exposed, and the lower part, where
electronic components are covered by a metal plate. Look on the lower
part, where the plate is located. You find the following connections:
• Infinet connection, on lower left side of lower part .
• Service Port, to the right of the Infinet connection, on lower part.
•Port for EMX 170 or SP 100 module, to the rig ht of service port.
On the right side of the divider are two more distinct parts—the upper
part, a series of relays lined up in two rows along the divider, and the
lower part, a small printed circuit board near the bottom of the cabinet.
Look on the small printed circuit board near the bottom. You find the
following connections:
• AC Power Connection, to the right of the lower part of the
controller.
• Voltage Selection Jum pe rs, just be low the AC powe r conne ction.

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.
The AC power connection is to the right of the lower part of every LCX
890 series controller. You must wire the AC cable to the three screws
on that board.
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 5 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.

1. Open the LCX 890 cabinet door.
Figure 8 shows the locations of the terminals for inputs, outputs, and
momentary switches on the LC X 890.
2. Notice the location of the first 16 inputs along the lower left
quadrant of the upper part of the controller. They are labeled inputs
1 through 16 on the printed circuit board. You must always wire a
switch to any of these inputs.
3. The next eight inputs are along the left side in the vertical center of
the lower part of the controller. They are labeled inputs 17 through
24 on the cover plate. You can wire a thermistor, voltage, or current
input to any of these inputs.

Wiring the Inputs
Now that you have located the inputs, you are ready to wire them.
Before you proceed, be sure you know which type of input you can wire
to each terminal. The first 16 inputs on an LCX 890 or LC X 898 must
always be switches and may not be any other type of input.
Caution
Do not remotely ground any part of the sensor wiring. Remote grounds
connected to the LCX 890 or 898 return te rminal could make the
controller 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 terminal s that retur n to the LCX 890 or 898.
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
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 within 3 in. (75 mm)
of the thermistor’s sensi ng tip.
LCX 890 Installation Guide 31
Caution
Follow the rules below when wiring inputs and outputs:
• Never lay wires across the surface of the pr inted 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. (25 mm) 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.
Wiring a Switch Input
Notice that the group of switch inputs are labeled IN1, RET, IN2, then
IN3, RET, IN4, and so on. The return terminal goes to the two inputs on
either side of it.
Figure 10 shows a switch wired to an input point. You follow this
diagram when wiring the first 16 inputs on the LCX 890. You may not
wire anything other than a switch to these 16 inputs.
Figure 10. Wiring Diagram for a Digital (Switch) Input
1 (input point 1)
RET (return)
32 LCX 890 Installation Guide
Follow these steps:
1. Loosen the screws for the first two inputs and their return terminal.
2. Slip the first wire for the first sensor under the input point screw for
input 1 and tighten the screw down on it.
3. Slip the first wire for the second sensor under the input point screw
for input 2 and tighten the screw down on it.
4. 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.
5. Repeat the steps 1 through 3 for each pair of inputs.
Wiring a Thermistor Input
Figure 11 shows a thermistor attached to a universal input point. One
lead connects to the numbered input terminal, the other to a return
terminal.

Figure 13 shows a current sensor wired to a universal input point. You
must wire a resistor across the input.
The exact number of Ohms resistance required varies based on the range
of current—while we recommend 249Ω for a 0 to 20 mA input, you can
also calc u late the appropriate resistance with th e fo llowing for mul a:

You then select the next standard resistor 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 toleranc e, the greater th e accuracy.) The watt -
age rating should be greater than or equal to watt. Be sure you check

Attaching the Output Relays
The outputs are on the upper part of the LCX 890 just to the left of the
divider. On the LCX 898, they are on the outer side of the left and right
dividers. A relay connects to each output.
This explanation covers installing relays on the LCX 890 and the righ t
side of the LCX 898. All output wir e s should enter fr om the right.
If you purchase Andover Controls relays, install them as follows :
1. Thread the wires through the opening provided on the divider.
2. Press on the square end of the relay so it latches to the opening in the
divider. Be sure the two large screws on the end of the relay are
facing the front of the cabinet.
3. Plug the plastic connector at the end of the wires onto the 5-pin
connector to the right of the output terminals and to the left of the
divider.
Caution
Be sure the blue wire is at the top and the yellow at the bottom. Otherwise, you could damage the relay.
4. Repeat the above procedure for each relay.
The outputs are numbered starting with the row to the right. The odd numbered outputs are to the right, the even to the left. To be sure of the exact
output number, follow the wires that connect the relay through the left side
of the divider to the terminal wiring area. The relay wires connect adjacent
to the output terminal with the corresponding output number.

5. Repeat the above steps for each output.
Locating/Wiring the Momentary Switches
Each output can be controlled in two possible ways:
• Through the software based on the setting of an input.
• Through a momentary switch (such as a motion detector or push
button) that you wire to the terminals labeled OUT on the other side
of the vertical divider from the output relay. They are each
associated with a particular output and labeled with the output
number.
As shown in Figure 2-1, on the LCX 890 the momentary switches are
all to the left of their corresponding output.
As shown in Figure 2-2, on the LCX 898 the momentary switches are
either to the left or to the right of their corresponding output.

Wiring a Single Momentary Switch
to Two Adjacent Outputs on LCX 890 or 898
Adjacent to each output are four terminal screws that you can wire a
momentary swit ch to. Whether you are wiring a four-wire device (one
that gives status feedback) or a three-wire device, you need a couple
of extra jumper wires long enough to provide a bridge between one
momentary switch terminal and the next. One jumper wire is for the
RED terminal a nd one for the BLK. You wire th e two adjace nt outputs
to the one momentary switch. The maximum length of wire you can

control it. You may have both, so that the software may set the lighting,
or the momentary switch ma y set it. You ma y set the lights manually
through the momentary switch, if you choose. But the softw are can
change the hardware setting at any time.
52 LCX 890 Installation Guide
The software can read status feedback from the outputs and the indicator light turns on if the output is ON (provided you selected the outputs
that give feedback).
Note
Multiple output terminals on the LCX 898 tha t are wired to the same
switch can be independently software controlled as separate points.
However, multiple output terminals on the LCX 890 that are wired to
the same switch cannot be independently software controlled. They are
considered a single point.
Connecting the EMX 170 or SP 100 Module to the EMX 170 or SP 100 Port
The EMX 170 or SP 100 port at the bottom of the controller just left of
the vertical center is where you can connect a n EMX 170 or SP 100 expansion module. This port has a built-in buffer box for the EMX 170 or
SP 100, so you wire the module directly to the port, without the buffer
box. Refer to the ACC EMX 170 Ins tall ation Guide or the SP 100 In-
stallation Guide for how to install the module.
If you need information on the EMX 170 or SP 100 module, contact
your Andover Controls representative.

Powering Up the LCX 890 or 898
Warning
Before powering up the controller, be sure the board is jumpered for the
correct input voltage.
Before you proceed, be sure the following are correct:
1. Be sure you have jumpered the proper input voltage.
2. Be sure the battery is conne cte d.
3. Be sure the AC power is wired properly. Check to be sure you have
connected all three wires.
4. Be sure the controller has a true earth ground.
5. Be sure you have used the proper cables and wires and correct
lengths.
6. Be sure you have properly labeled the tag with the name of the
controller before removing it.
7. Be sure you have properly wired the Infinet cable.
8. Be sure you have properly connected the Infinet cable shields.
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. The CPU light begins flashing and flashes every .2 sec.
2. The TD light immediately starts flashing (or starts flashing after you
let go of the RESET button) to show data is being transmitted.
54 LCX 890 Installation Guide
3. The RD light begins flashing only if data is being received from
other controllers on the network. This may not happen immediately.
4. If the CPU light flashes more slowly than normal, every .4 sec, it
means the CPU has failed a ROM test. If it flashes more quickly than
normal, every .05 sec, i t has f ail ed a RAM test. If the CPU does not
flash at a normal rate, contact your Andover Controls representative
for assistance.
Connecting the Battery
When you have the controller mounted, find the AA battery in the lower
right corner of the lower part of the controller, to t he left of the AC power voltage jumpers. Remove the plastic tab beside the clip on the battery
to activate the battery.
The battery is an 1.8 A-hr 3.6 V primary lithium battery that runs the
real-time clock and maintains RAM and realtime clock when AC power
goes out. The battery is DOT-certified.
Reset Button
The RESET button is the red square button just above the battery on the
far lower right side of the LCX 890 board and on the lower left side of
the LCX 898. You press it to restart the controller without erasing memory. The same events occur as described under Power Up the LCX 890
or 898.
Connecting the Andover Controls Service Tool
The SERVICE POR T on the left side of the bottom of the controll e r,
immediately to the left of the EMX 170 or SP 100 port, is to connect the
Andover Controls Service Tool to an LCX 890. The service tool accesses all LCX 890s and other Infinet controllers on the same network. For
information on availability of the Andover Controls Service Tool, contact your Andover Controls representative.
