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.
