LCX 890 Installation Guide 1
Setting Up an LCX 890 Series
Controller and Infinet
The LCX 890 family of controllers are lighting controllers, designed to
connect to lights and switches that control those lights. You can have up
to 24 relays for controlling lights, with or without the status feedback op-
tion on an LCX 890 and up to 48 relays on an LCX 898. Each output can
have a momentary switch, such as a motion sensor or other occupancy
sensor, that sends a command to the light.
You may also connect an EMX 170 or SP 100 SmartSensor module to
any LCX 890 series controller.
This manual covers the following:
• Site/System Setup Requirements
• Installing the LCX 890 or 898
• Powering Up the LCX 890 or 898
Warranty Registration

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 re-
ceive 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.
Cable Limitations
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 module.

4 LCX 890 Installation Guide
Note
You must use shielded cables for 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-twisted-
pair, tinned, shielded copper wire. Use the following cables1or their
equivalents:
• Brand Rex # H 9002 (single-pair)
• Anixter # 9J2401021 (single-pair plenum cable)
The cable should have a nominal impedance of 100 Ωand a nominal ve-
locity of propagation of 78%.
Capacitance of Infinet cable should be nominal, below 12.5 pF/ft (41 pF/
m) between conductors and below 22 pF/ft (72 pF/m) between the con-
ductor connected to ground and the next conductor.
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 Corporation 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 ground all controllers.
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 municipalities 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 corro-
sion acts as an insulator, raising the potential of the pipe with respect to
the ground.
When lightning strikes in the area of the installation, 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 building 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 lightningalso impact the reliability
of Andover Controls equipment.

6 LCX 890 Installation Guide
Inspecting the Ground
You can check your ground as follows:
1. Check your ground byfirst 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
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 controllers operate in rooms with temperatures ranging
from 32 to 120°F and with humidity between 10 and 95%, noncondens-
ing. If you connect a SmartSensor, the temperature can range from 32
to 104°F.
The controller is in an Underwriter Laboratories approved enclosure.
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 relays
that do not give status feedback (Andover Controls Part # 01-0100-
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 re-
quired, it sends a signal to the output relay. The relay mechanically

LCX 890 Installation Guide 7
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 light is available in the software if you use relays that
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 following 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 control-
lers 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.

8 LCX 890 Installation Guide
Digital Inputs
The first 16 inputs on all LCX 890 controllers are digital, for switches.
The controller can read the settings of these switches.
All digital inputs have an input impedance of 220KΩreferenced to
5.000 V.
Universal Inputs
The last eight inputs (not including the EMX 170 port) on the LCX 890
or LCX 898 (17 through 24) are universal. Thelast eight inputs onthe are
universal.Universalinputsareforanytypeofsensor,suchasthermistors,
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—10KΩreferenced to 5.120 V

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.
