SYSTEM OVERVIEW • INTRODUCTION
Chapter 1: System Overview
Leviton’s Centura System is the convenient, Fluorescent Dimming and Energy Management System.
The system is designed with both the average user and the building administrator in mind.
By combining a number of state-of-the-art lighting control and sensor products, Centura provides
numerous functional advantages.
• Daylight Harvesting Exploits Outside and Ambient Light
• Lights Turn On and Off Automatically Based on Occupancy and Lighting Needs
• Computer Control Over Light Fixtures
• Lighting Adjustments Using Hand-held Remote
• Centralized Control Over Lighting System Settings
• Interface with Auxiliary Systems for Additional Savings and Safety
(HVAC, Emergency, Time Clock, and Loadshed)
As you will see, Centura provides a number of options for interfacing with the system.While both
the average user and the lighting administrator can, of course, use any of the wall-mounted controllers
or the remote control to adjust lighting, Leviton also provides “Personal Dimmer” software tailored to
the needs of each group.The average user, who wants to know how to use the system to make
temporary and long-term adjustments to your lighting, should reference Chapter 2 next. If you are
a building administrator responsible for lighting, you will also be interested in Chapter 3. Before
you move on, take a few minutes to make sure you are familiar with a few concepts that are essential
to Leviton’s Centura system.
INTRODUCINGTHE CENTURA COMPONENTS
Centura consists of a number of components that can be mixed
and matched to create a lighting system with tailored levels of
automation and user control. Every Centura system must
incorporate the CN100 Centura Dimming Power Pack (Figure 1-1),
which retains all settings and serves as the central link between
peripheral devices. After that, what you choose to incorporate into
your Centura System is up to you. It may vary from room to room
depending on: the needs of the user, if it has windows or not,
existing occupancy patterns, real-life safety issues, and a number
of other variables.

SYSTEM OVERVIEW • DEFINITIONS
Light Maintain Level
The level of light that the photocell
measures and that the Centura
System will try to constantly
maintain when using the
daylight-harvesting feature.
This light level should be set to
the optimal level for a specific
user in a specific area of a room.
Occupancy Sensing
Motion sensors that monitor
a space and turn lights off after
everyone leaves and on again
when someone returns.
Automatic light switching is
hands-free and provides users
with top convenience. Occupancy
sensors can provide considerable
energy savings by ensuring that
lights are not left on by mistake.
Address & Address Set
Within the Centura System, an address
is a unique label that groups Centura devices together so that specific controllers
and Personal Dimmer locations control specific fluorescent fixtures.The Address
Set refers to all the components that are grouped together under one address.

KEY CENTURA DEFINITIONS
Leviton's Centura Fluorescent Dimming & Energy Management System is a more comprehensive
system than you may be used to. In order to understand Centura, you should understand a few, key
concepts and terms.
Daylight Harvesting
Using surrounding ambient (often natural) light to supplement artificial light in order to keep a constant
lighting level while saving electricity. Within the Centura System, daylight harvesting requires connecting
the CN100 Power Pack directly to an ODC0P photocell, light fixtures, and a dimming controller and/or
software and SmartJack combination.

SYSTEM OVERVIEW • SENSOR COMBINATIONS
HOW DIFFERENT SENSOR COMBINATIONS OPERATE
Because the Centura System is a combination of components that may vary from installation to
installation, as well as from room to room, how it works is dependent on which components are
selected.The two components that have the greatest impact are the photocell and the occupancy
sensors, as you can see by the examples below.The devices or methods you choose for interfacing
with the system in a particular room are more a matter of preference (for example, using a computer
or a traditional switch) and have little effect on how lighting will function.
Keep in mind that you can have a number of different setups for different address sets within a
single installation. For example, Address Set A may be for a cafeteria and may have a photocell
but no occupancy sensors, while Address Set B may be located in a private office and incorporate
both components.
Also note that the system may not behave as described when overriding Emergency, Service Switch,
or Time Clock inputs are active.
•When in Emergency Mode, lights will remain on at full brightness.
•When the Service Switch is activated, lights will stay off so maintenance and repairs on lighting can
take place.
•When a Time Clock setting is active, lighting behavior may be dictated by company-wide settings.
These scheduled lights off occurrences can be overridden by manual switching or occupancy
detection.
Photocell Only
In general, the photocell will help keep an area lit at the same approximate level (Light Maintain Level) at
all times with automatic dimming and brightening. Although the light fixtures themselves may dim and
brighten, depending on how much natural and artificial ambient light is coming into a room, there will be
little, if any, perceptible difference in the level of lighting. Lighting adjustments to maintain the desired
light level will happen automatically but may be overridden by manual adjustments if certain tasks
require different lighting.You may notice that 30 minutes after you’ve manually adjusted the lights to a
brighter level, they will return to the Light Maintain Level by themselves. Environmental regulations in
some states require this override.
Note:The photocell measures light in a relatively finite area: a 60ºpattern from itself.The system will
adjust lighting levels based on the measurement of light within that area alone, so lighting levels
may vary in different areas within an irregularly-shaped or extra large room. Placing additional,
separately controlled lamps or fixtures in certain areas can compensate for these conditions.
Occupancy Sensors Only
If you’ve got an occupancy sensor (or several sensors) in an area, the lights should immediately turn on
to the last brightness setting when someone enters the empty room, and automatically off again after
everyone leaves it.The period of time it takes for lights to turn off can be seconds or minutes, depending
on occupancy patterns, user-configurable settings, and model number.

SYSTEM OVERVIEW • SENSOR COMBINATIONS
Photocell PLUS Occupancy Sensor
The combination of both types of sensors automates on/off switching and dim/bright fluorescent
lighting adjustments.
What to Expect as You Enter the Room
When you enter an empty room, the lights will turn on to the Light Maintain Level or the level the lighting
was manually set to at the time the lights were turned off if that level was lower than the Light Maintain
Level.The lights will remain off if sunlight or other artificial light is enough, by itself, to meet the Light
Maintain Level.
What to Expect while You’re in the Room
As you remain in the room, the lighting level should appear constant even when outside or indoor
ambient lighting conditions change throughout the day because Centura will automatically dim and
brighten the lights, so you won’t have to.This means it won’t get too dark in the room because it’s cloudy
outside or too bright because it’s extremely sunny.
What to Expect whenYou Leave the Room
When everyone leaves the room, the lights will turn off after a period of seconds or minutes—depending
on model, occupancy patterns, and/or manual settings.
Without Either Component
Without either the photocell or occupancy sensor, the Centura System will function as a dimming system
that although, not automated, provides a number of different manual control options—including lighting
adjustments via computer and a hand-held remote control.

BASIC LIGHTING CONTROL • BASIC CENTURA SETTINGS
Chapter 2: Basic Lighting Control
Centura offers a number of different methods for adjusting lighting levels and settings.The most
traditional method is, of course, using wall-mounted switches or controllers and Leviton provides three
options.The CN221 and CN220 are designer-style Decora rocker switches, while the CN200 is a
pushbutton entry pad with an infrared receiver for use with the next option: the NE200 remote control.
Finally, the Leviton Personal Dimmer is a familiar Windows-like graphical user interface that enables you
to adjust light levels and basic settings, and turn lights on and off from your computer.
BASIC CENTURA SETTINGS
Although basic lighting control needs no explanation, you may not be familiar with the terminology we
use to describe each certain setting or why you might want to adjust each setting.
Light Maintain Level
The level of light that the Photocell measures and that the Centura System will try to constantly maintain
within a daylight harvesting system.
Maximum Light Level
The maximum Power Pack output is adjustable between 60% and 100% of the maximum ballast output.
By setting a maximum light level under 100%, you may be able to realize energy savings without
impacting the perceived brightness in an area. For example, lights set at 90% may not appear any less
bright than at 100% output.
Minimum Light Level
The minimum Power Pack output is adjustable between 0% and 40%, which is greater than the minimum
ballast output.The ability to adjust this level can be very useful because some ballasts are not reliable at
the lowest dim levels, causing light bulbs to flicker.*
Preset Light Levels
The four brightness levels that the remote can store and select. Setting Preset Light Levels allows you to
adjust lighting to an exact level by pressing a single button on the remote.This is especially useful where
repeated tasks require specific levels of lighting.
Unoccupied State
Any time the occupancy sensor detects an absence of motion, it can either turn the lights off or dim
them to the Minimum Light Level, depending on the status of this setting.You might want lights to stay
on at a low level when an area is empty as a safety measure or as a theft deterrent.
*This value represents the Power Pack output, not the ballast minimum light output.

BASIC LIGHTING CONTROL • USING AN LPD
Using a Leviton Personal Dimmer
For Basic Control of Lights
The Leviton Personal Dimmer offers two different interfaces for adjusting lights.The main
LPD screen (Figure 2-5) is a full-featured tool that displays system status, access to
settings, and on-line help (if help is not active, check www.leviton.com/centura for
software updates). Always open the LPD by clicking on the LPD icon (to right).
Figure 2-5:
Main LPD Screen
Figure 2-6:

TURN ON: Click the On button on the main LPD screen and lights will fade on.
TURN OFF: Click the Off button on the main LPD screen and lights will fade to off.
DIM: Click and hold the slider bar and move it downward until you reach the desired light
level, OR move the slider downward on the Quick Slider.
BRIGHTEN: Click and hold the slider bar and move it upward until you reach the desired light level,
OR move the slider upward on the Quick Slider.
SET TO FULL BRIGHT: If the lights are on, click the On button on the main LPD screen.
If the lights are off, click the On button TWICE.
To Get the Quick Slider onto Your Desktop Minimize the LPD and RIGHT click on
the LPD icon in the right-hand corner of the task bar on the bottom of your desktop.
The Centura Quick Slider lets you dim or brighten your lights using a small window
that you can keep active in the corner of your computer desktop. Note:You cannot turn
lights on or off with the Quick Slider (Figure 2-6).

To Adjust Settings
You can set all levels (Maximum Light, Minimum Light, and Light Maintain (Daylight) Level) in either of
two ways: (1) type the desired percentage value in the white Levels box or (2) click Set Current to set
the level at the level the photocell is currently measuring, in other words, at the current light level. See
Figure 2-7.
Figure 2-7: Adjusting Light Levels on the Set Parameters Screen
Unoccupied State
Unless instructed otherwise, a Centura System incorporating an Occupancy Sensor will turn lights off
when no motion is detected. If you want the lights to instead revert to the Minimum Light Level, check
the “Lights at Min when Unoccupied”box.
Foot-candle Option
Although you do have the ability to switch the unit of light measurement from percentage to foot-candle
through the LPD, Leviton suggests you ask the person in charge of your lights to help you do this.
Resetting this unit requires use of a light meter.

ADMINISTRATING CENTURA • INTRODUCTION
Chapter 3: Administrating Centura
INTRODUCTION
While the average user will utilize Centura to merely adjust their lights and a few, related settings, the
average lighting administrator will find Centura to be a comprehensive tool for system setup,
programming, monitoring operations, and providing support to building occupants. This chapter runs
through the software installation process, system setup, software testing, and finally, how to use
Centura-especially its LPDA software—to perform a variety of support and system administration tasks.
Restricted Access
Because the lighting administrator may require access to system-wide settings that would be
inappropriate for the average user, Centura provides the lighting administrator with their own, special
software: the Leviton Personal Dimmer Administrator. Administrators can also gain access to a number
of settings in the LPD interface that the general user cannot access by using a password. By giving the
administrator sole control over a number of variables, management is empowered with the ability to set
company-wide lighting standards, institute energy management policies, and ensure adherence to
environmental regulations.
Educating the Average User
Although using any one of three Leviton controllers, the hand-held remote control, or the LPD to control
individual Centura lighting is quite simple, users may have never been exposed to certain Centura
features and functions, like daylight harvesting and computer control over lighting. For this reason, we
suggest you give each user—or at minimal, anyone who using the LPD-a copy of this User Guide.The
first two chapters will be especially useful for them.
Rules of Operation
If you’re administrating a Centura lighting system with daylight harvesting and occupancy detection, it is
important to understand the rules that determine how lighting will automatically switch and adjust.
IMPORTANT: In order for PC based operations to function, you must keep the LPDS program open and
running on the Centura server. If the server goes down, you must open this program upon restart.
Daylight Harvesting
The Power Pack attempts to maintain a user-preset level of light in a room by adjusting attached fixtures
to compensate for other available light.The Power Pack continuously receives the measurement of
ambient light recorded by the photocell.There are three basic states from which automatic regulation
continually takes place to keep ambient light at the desired level, with standard results:
1. Measured light level = Light Maintain Level ➔Output to lights remains constant
2. Measured light level < Light Maintain Level ➔ Lights are brightened
3. Measured light level > Light Maintain Level ➔Lights are dimmed
In general, the Power Pack will adjust a load’s output level to the lowest light level called for by an active
input: Leviton refers to this as the Least Light Law. For example, if the Power Pack is turned on (either
manually or by occupancy) and the Light Maintain Level calls for a lower output level than the last preset
manual level, the lights will adjust to the lower Light Maintain Level. On the other hand, if the manual
preset level is lower than the Light Maintain Level and the Power Pack is turned on, the lights will adjust
to the manual preset level—because it is the lower level in this case. (Note:You CAN manually override
this level.) The Least Light Law is applied at all times, except when overriding Emergency, Service
Switch or Time Clock inputs are activated. (See CN100 Dimming Power Pack Input Prioritization, on
next page for a complete accounting of how the Power Pack prioritizes the various inputs.)
If the lights were at a level that was set manually at the time they were turned off, either manually or not,
the dimming pack will retain that last manual setting and return to that setting when the lights are turned
on again. Exception: If using daylight harvesting and the Light Maintain Level is lower than the last
manual setting, the lights will automatically return to the Light Maintain Level because of the Least Light Law.

13
ADMINISTRATING CENTURA • INTRODUCTION
Additional Rules
1. If someone enters a room when the lights are off, the lights will remain off if the ambient light level is
already equal to the Light Maintain Level.
2. To preserve bulb life, even if there is enough outside light coming into a room to meet the Light
Maintain Level without artificial lighting, the lights will remain on at a minimal level. Too much
switching of fluorescent bulbs can diminish bulb life.
3. If someone enters a room when the lights are off, the lights will remain off if the ambient light level is
already equal to the Light Maintain Level, even though the occupancy sensor detects motion.
CN100 Dimming Power Pack Input Prioritization
The CN100 Dimming Power Pack may receive several inputs at any one time and it prioritizes these
inputs in the following order. Being aware of this order provides additional insight into how the system
will operate.
1. Service (Air Gap) Switch: keeps lights off so service can be performed.
2. Emergency: lights switch to 100% brightness when system goes into emergency mode.
3. Program Mode: during reprogramming of default values and addresses, service switch and
emergency mode settings will always take precedence.
4. Occupancy On/Off: turns lights on and keeps them on as long as a sensor detects occupancy, and
off when no motion is detected.
5. Manual Off: when a user turns lights off using a switch, remote control, or computer interface.
6. Manual On/Brighten/Dim: when a user adjusts lights using a switch, remote control, or computer.
7. Time Clock: lights will adjust based on Time Clock schedule.
8. Loadshed: decreases load output by a user-configurable percentage during loadshed periods.
9. Light Maintain Level: lighting adjusts its own output to maintain a user-set light level within a
photocell’s area of detection.
Additional Functionality
Tie-in to HVAC Systems
Any Centura system incorporating occupancy sensors will be tied to on-site HVAC systems through the
Power Pack’s built-in relay. This will automatically switch heating, ventilation, and air conditioning
systems off after a room is left unoccupied for a period of time, and back on again when motion is
detected.
Loadshed Level Definition
A loadshed level is the reduced level lights will be set to when the loadshed mode is activated. Centura
can help administer a loadshed policy that reduces electric bills by defining how much electric
consumption will be lowered whenever you manually activate the mode (most likely during utility-defined
peak periods).
Time Clock Scheduling
Centura lighting can also be driven by a Time Clock function that turns lights off automatically. In
installations where everyone regularly leaves the building at about the same time, setting a Time Clock
sequence can ensure that lights are not left on inadvertently, wasting electricity.This 30-minute lights-off
sequence is especially useful where there are NO occupancy sensors.

ADMINISTRATING CENTURA • DEFINITIONS & ADVANCED SETTINGS
Definitions & Advanced Settings
Familiarizing yourself with following terms, in addition to those listed in the previous chapter (Light
Maintain Level, Maximum Light Level, Minimum Light Level, Preset Light Levels, Unoccupied State) will
help you to understand the Centura System so you can properly administrate it. Many of the settings are
covered in more depth later in this chapter.
Address
An address is a numeric label that identifies a node.The LPD and LPDA programs sometimes substitute
Node ID or CAN ID for the term “address”.
Address Set
The Address Set refers to ALL Centura components that are assigned the same address.
Foot-candle
A unit of measurement for light that may be displayed on the main LPD screen, instead of a percentage.
Light Regulation
The rate that lighting adjusts within a daylight harvesting system.
Manual Timeout
When this setting is active, which is the default setting, manual adjustments to lighting will remain active
for only 30 minutes. After 30 minutes they will revert to the Light Maintain Level if it is dimmer than the
manually adjusted level.This timeout conforms to environmental regulations, including California’s Title
24. It can be disabled.
Dim/Bright Rate
The period of time the lights take to reach the new, manually selected level of light measured in 8.3ms
cycles. Changing this can contribute to a certain ambience or accommodate personal preferences.
ON Fade Rate
The speed at which the lights brighten to the Light Maintain Level (or preset level when there is no
photocell) measured in 8.3ms cycles. Changing this can contribute to a certain ambience or
accommodate personal preferences.
OFF Fade Rate
The speed at which the lights dim to off measured in 8.3ms cycles. Changing this can contribute to a
certain ambience or accommodate personal preferences.

15
ADMINISTRATING CENTURA • SETTING UP THE LPDA
SETTING UP THE LPD/LPDA
There are a few steps that must be taken in order to implement control over the Centura System through
a PC. First the administrator must compile certain information about the Centura installation that will be
used to configure the software.Then the software must be installed, and the user list generated.The last
step is to follow a short procedure to test that the software is functioning properly.
These instructions assume that all Centura components have been installed, and initial addressing has
been performed as part of the installation. Note: The software can also be used to perform the
addressing function instead of the wall controllers. See Page 25 for instructions.
Gathering Information
Because you will need this information throughout system setup, you should compile
the following data before starting the actual setup:
•Names of all server computers running Leviton HTTP Server
•Computer names of all users of the Centura system
•Which address sets correspond to which server computers
•Number of the serial port to which the SmartJack is connected
We suggest you create a chart, similar to Figure 3-1, to help you keep this information organized.
The list should be compiled for all addresses and computers you plan on providing with LPD access,
even if they are not yet installed.There is a blank chart at the end of this guide, which you can use for
this purpose.

ADMINISTRATING CENTURA • INSTALLING THE SOFTWARE
Installing the Software
Once this information is compiled, it’s time to install the software.You cannot install Leviton Personal
Dimmers without installing LPDA and HTTP Server software, but you can install the latter two without
the LPD if the average user will be using only wall controllers or remote controls to adjust lighting.
HTTP Server Software (LPDS)
You must install on a Centura server; in other words, a PC connected to a SmartJack.
Note: Upon successful installation, an LPDS shortcut will be added to your computer’s
desktop and Leviton HTTP Server will be added to the startup menu.
1. Put the Install Disk in the CD-ROM drive.
2. Run the setup program, setup.exe, under the LPDS directory. Follow the directions on screen.This
will install the Leviton HTTP Server software.
If the SmartJack is connected to Serial Port Number 1, the installation is complete. If it is not,
continue to Step 3.
3. Open the SerCnf.txt file (found in the directory ...Program Files\Leviton\LPDS using a text editor such
as Notepad.The file should resemble Figure 3-2.
