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 option 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

Your warranty is effective for 18 months starting on the date the system is shipped.

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.

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.

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 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 velocity 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 conductor 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 corrosion 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 lightning also impact the reliability of Andover Controls equipment.

LCX 890 Installation Guide

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

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 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 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 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 universal. The paragraphs that follow give the requirements of each type of input.

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 220KΩ referenced 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. The last eight inputs on the are universal. Universal inputs are for any type of sensor, such as thermistors, 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—Permanent (factory)

EMX 170 Inputs

If you have an EMX 170 on the EMX 170 port, it is an additional input, numbered 25.
