INTRODUCTION
The Dimming Power Pack, Cat No. CN100, is a multi-purpose lighting control. It is both a dimmer and an energy
management device. For energy management, the CN100 can perform daylight harvesting, and be interfaced to
occupancy sensors. For dimming purposes, controllers can be connected for manual control. There is an optional
computer interface to allow control from a desktop computer. There is a low voltage relay for interfacing to HVAC
systems. Building management functions such as timeclock, loadshed and emergency can be enabled with the
computer interface.
DESCRIPTION
The Dimming Power Pack is a versatile lighting control, and can be used in different ways by connecting up different
peripherals. The peripherals are occupancy sensors, photocells, wall controllers, handheld remote controls, and
personal computers. Please refer to the Centura Installation and User Manuals for a complete description of the
Centura system and its functionality,
found on the listed website.
The Dimming Power Pack can be used with Centura and LCnet devices.
The Dimming Power Pack's main features are as follows:
Manual Override/Timeout: A manual override is when the lights are brightened or dimmed by the user. There are
two ways the manual override works. The Manual Timeout selection chooses between the following two options:
• A manual override may be permanent, in the case of Manual Timeout Disabled. If a user changes the lights from
the Light Maintain level, they will stay at that level until the lights are turned OFF.
• A manual override may be temporary, in the case of Manual Timeout Enabled. If the user changes the light level,
the lights will stay at this level for 30 minutes, then they will revert to the Light Maintain level.
Max. Light Level: The Dimming Power Pack can be programmed so its maximum output is less than the maximum
ballast output. This level is adjustable between 60% and 100%.
Minimum Light Level: The Dimming Power Pack can be programmed so its minimum output is greater than the
minimum ballast output. This level is adjustable between 0% and 40%.
Unoccupied State: When the occupancy sensor signal indicates there is no motion, the Power Pack can be
programmed to dim the lights to minimum, or turn the lights OFF. Pressing an OFF button (such as from a Controller)
will always turn the lights OFF.
Daylight Harvesting: The Dimming Power Pack will perform Daylight Harvesting (Daylighting). This is when natural
light is used to supplement the light provided by the controlled ballasts, in order to keep a constant level of light in the
room. It works as follows:
The Power Pack receives a measure of the ambient light from the photocell (current light level). This light level is
compared to a preprogrammed light level (the Light Maintain level). If the current light level is less than the Light
Maintain level, the Power Pack BRIGHTENS the lights. If the current light level is more than the daylight maintain
level, the controller will DIM the lights. This will continue until the two levels are equal.
NOTE: When the occupancy sensor triggers the lights to turn ON, the Power Pack will read the current level from the
photocell. If it is less than the preprogrammed level, the Power Pack will keep the lights OFF.
Network Inputs: The dimming power pack can respond to commands sent over the network of timeclock, loadshed
and emergency.
A. Time Clock: A preprogrammed sequence for end of daylight control (the sequence is programmable over the
network).
B. Load Shed: Reduces the current light output by 25% (programmable over the network)
C. Emergency: The lights turn to full brightness
Fade Rates:
ON/OFF: Speed at which lights fade ON and OFF.
DIM/BRIGHT: Speed at which lights fade DIM and BRIGHT.
Input Resolution: The Power Pack has various inputs. The inputs may request the
Power Pack to be in different modes. To determine which input to accept, the inputs
are given priorities (refer to Table 2).
Example 1 - If the occupancy sensor detected an absence of movement, the Power
Pack will turn the lights OFF. However, if the Emergency input then activates, the
lights will turn on to full BRIGHT.
Example 2 - If the Controller is in Program Mode and the Loadshed input activates,
the Power Pack will not change the light level, it will wait until the Controller is taken
out of program mode.

Least Light Output: Besides priority, the various inputs will call for different light levels. To resolve the different light
levels, the controller follows the rule of least light output. This rule determines which input is calling for the least light.
The Power Pack then outputs that particular light level.
Once the Power Pack accepts a priority it will then determine the light level using the rule of least light. The following
inputs all may call for a different light level:
• Emergency
• Loadshed
• Manual DIM/BRIGHT
• OFF (occupancy or manual)
•ON
• Photocell
• Program Mode
• Service
• Timeclock
NOTES:
A. The Power Pack will output the lowest light level called for by any of these inputs.
B. This rule is only used when the lights are ON.
C. Manual control can always be used to override the rule of the Least Light Output.

OPERATION
INPUTS
Occupancy: Any Leviton low-voltage occupancy sensor can be connected to the Power Pack.
When the occupancy sensor does not see any motion and completes a time-out, it will signal
the controller to turn the lights off. The Power Pack will further wait 10 seconds before turning
off the lights.
Photocell: The photocell measures ambient light level and sends a signal to the Power Pack
proportional to that level. For more information, see the Daylight Harvesting section.
OUTPUTS
Dimming Control: The Gray and Violet wires provide a control voltage to provide dimming to
the ballasts. The control voltage varies between 0.6 - 10VDC.
Low-Voltage Power Bus: +24VDC
HVAC Relay: The HVAC relay is closed whenever the occupancy detector is signaling the
Power Pack that there is motion detected. All of the relay contacts are provided, common,
normally open and normally closed (see wiring section).
LED FUNCTIONS (refer to Table 3):
TO OPERATE:
With Controller, Photocell and Occupancy Sensor:
The lights will turn on when motion is detected, and turn off when no motion is detected. When
the lights turn on, the Power Pack will follow the rule of least light, and input resolution, to find
the correct light level. Use the Controller to override the lights if desired.
With Photocell and Controller:
Lights must be turned on and off manually. When the lights are turned on, the Power Pack will
follow the rule of least light, and input resolution, to find the correct light level.
Refer to Centura Installation Manual and User Guide for Troubleshooting and System
Installation details.
NOTE: Gray and Violet wires for dimming control of ballast are provided through both low-voltage and high-voltage wiring
port. The wires coming out of the high-voltage wiring port are considered low-voltage, but have the appropriate sized
insulation for wiring with other high-voltage wires. Local building codes will determine which wires to use.
