2. The Photocell can either be fastened onto the ceiling surface, flush mounted into the ceiling, or installed in a 4” (10 cm) round or octagonal outlet box, depending on ceiling
material and local codes.
3A. TO FASTEN THE PHOTOCELL ONTO THE CEILING SURFACE: Attach the outer shell provided to the ceiling at the desired location using two (2) #4 screws and
appropriate anchor hardware, where necessary. For concealed wiring, access to the space above the ceiling is required, as well as a hole in the ceiling above the Photocell
to bring the wires from the Leviton Power Pack. Make all connections as described in Steps 4 through 9. Carefully feed the wires into the hole and press the Photocell body
into the outer shell until the rim is flush with the shell. NOTE: If wiring is to be run exposed along the ceiling, carefully trim the plastic from the indentation in the side of the
outer shell and lay the Photocell wires through it before tightening the shell onto the ceiling.
3B. TO FLUSH MOUNT INTO THE CEILING (ONLY ALLOWS CONCEALED WIRING, THE OUTER SHELL IS NOT USED): Cut a 2” (5 cm) diameter hole through the ceiling.
Make all connections as described in Steps 4 through 9. Carefully feed the wires back through the hole and press the Photocell into the hole until the rim is flush with the ceiling.
4. Prepare the Photocell lead wires by removing 3/4” (1.9 cm) of insulation from each lead to expose bare copper wire. Make sure the ends of wires are straight.
5. Determine length of low-voltage wires needed to connect Power Pack to Photocell. Use wires suitable for low-voltage wiring, according to local electrical code.
6. Route
low-voltage wires from Photocell location(s) to Power Pack location(s).
NOTE: Refer to Power Pack Installation Instructions for complete control unit wiring details.
7. Prepare low-voltage wires by removing 3/4” (1.9 cm) of insulation from each lead to expose bare copper wire. Make sure the ends of wires are straight.
8. Connect low-voltage wires per Figure 2 as follows: BLACK to Ground, RED To Power and ORANGE to the Power Pack Photocell Input. Twist strands of each separate
wire connection tightly, and push firmly into appropriate wire connector. Screw connectors on clockwise ensuring that no bare conductor shows below the wire connectors.

DESCRIPTION
PHOTOCELL AND DAYLIGHTING OPERATIONS
PHOTOCELL OPERATION
CALIBRATION
SETTINGS
INSTALLATION
The Cat. No. ODCØP-S0W Photocell responds to ambient light levels in the viewing area and provides an output that is representative of the ambient light intensity. The output is switched on
or off based upon the Daylight Design level. The ambient light measured is the light from any light source in the visible spectrum. The Photocell does not distinguish between natural sunlight
and artificial light. It contains a sensor which is color and spatially corrected to provide a true representation of changes in lighting levels which a person perceives. The Photocell operates off of
low-voltage power. The input voltage needed is 12/24VDC with approximately 10mA current consumption. The photocell measures ambient light between 0 and 750 footcandles, and the output
voltage switches between 0 and 12VDC or 24VDC. An output of 0VDC corresponds to a light level below the daylighting setpoint, and an output of 12VDC or 24VDC corresponds to a light level
above the daylighting setpoint. This sensor can be used to enable Daylight Harvesting, using Leviton Power Packs. The sensor measures the ambient light that actually falls upon it within a 60°
cone extending downward from the sensor (refer to Figure 1). This is the light that gets reflected to the ceiling from the walls, floor and furniture. NOTE: Care must be taken when choosing
the mounting location. It is recommended that the sensor be mounted directly above the work space, such as the desk, conference table or computer terminal. Mounting location is important
because the ambient light level will be different at different points in the room, depending on the location of the windows, lighting fixtures, wall colors, etc. The ambient light at the doorway can be
much less than that at the windows, corners of the room, or especially on the ceiling. Therefore, it is important to measure the ambient light level over the workplace.
After the sensor is installed, the photocell must be configured correctly to control and/or maintain the desired light
level and gain additional energy savings. Prior to configuring the photocell, the installer should understand Closed
Loop Daylighting. The installer must decide which application best fits the customer’s needs before configuring and
calibrating the device. For best calibration results, personnel should maintain at least a 6 foot distance from the device
2 minutes after the start of Auto and Manual Calibration. NOTE: to disable photocell or cancel calibration turn knob
to SET/OFF for longer than 5 seconds (RED LED followed by solid YELLOW LED). If the light level falls below 10
lux during calibration, that calibration will fail and the LED will be solid BLUE. The device enters Off Mode when this
occurs. When the photocell is disabled (Off Mode), the device has no calibrated DDL and will always indicate that light
is needed. When changing photocell modes or recalibrating, disable photocell (turn knob to SET/OFF for longer than 5
seconds) and follow directions below:
Procedure – Manual Calibration
1. Turn the photocell knob (fully counterclockwise) to SET/OFF for 2 seconds (LED will be solid RED indicating the
device has entered Manual Calibration mode).
2. Then turn the knob to SETPOINT (1X) - see Figure 3 - Settings (below).
3. Lights are forced ON for 3 minutes
4. LED blinks RED (3 minutes). Optional - During this time, the DDL can be adjusted by turning the knob up or
down. NOTE: The LED blinks BLUE when the knob setting has changed.
5. When Manual Calibration is complete, the LED will resume normal operation.
6. The device is now operating in Manual mode.
Procedure – Auto Calibration
1. Turn the photocell knob (fully clockwise) to AUTO (LED will be solid GREEN for 24 hours indicating the device
has entered Auto Calibration mode.
2. When Auto Calibration is complete, the LED will resume normal operation.
3. The device is now operating in Auto mode.
NOTE: Lights must be left ON for the duration of auto calibration.

Daylight harvesting is used for additional energy savings. The photocell holds the lights OFF when sufficient
ambient light is present; or ON when sufficient light is not present. Light levels are measured in foot-candles or lux. A
classroom or office space design is usually configured to maintain approximately 35-50 foot candles/350-500 lux at
the work surface. The light maintain level a.k.a. The “Daylight Design Level” (DDL) is set per the calibration section of
this install sheet.
•
In order to keep the lights from needlessly cycling ON and OFF, the OFF trigger point is set at a higher light level
than the ON triggers point. In addition, there is a delay time that must be met which requires the light level to be
above or below the trigger point for a period of time before a light change occurs. For example, there may be a
10% hysteresis gap between the OFF and ON trigger points, along with a 3,5,10,20,30 minute delay time to turn
OFF the lights and a 1 minute time delay to turn ON the lights.
•
OFF and ON trigger point levels can be adjusted at any time using the Photocells Set Point knob.
NOTE:
•
Quick adjustments can be made to the DDL by adjusting the Photocell Set Point after calibration has been
completed. The Delay Time for lights ON/OFF will be reduced to 30 sec ON/OFF after the Photocell Set Point
knob change is recognized. The reduced delay time will expire 2 minutes after knob change occurs.
•
The LED blinks BLUE when either knob setting has changed.
•
To disable photocell or cancel calibrations turn the knob to SET/OFF (RED LED, solid YELLOW LED).
The graph in Figure 4 tracks the value of a linear photocell throughout a day. It is assumed that it is a cloudless day
and that the desired light level is the same level without external light influence and only by the fixture(s). At the far
left, the lights are ON because the area is occupied and since it is still night, there is no contribution from daylighting.
As dawn arrives, the photocell level begins to increase as the daylight increases. In order to keep the light level from
dropping below the trigger point, and in this case
below the desired light level in the area (DDL),
the trigger point is set to 2.5 times the level read
with only the fixture(s). That way, the light is still
adequate to hold the lights OFF. This is shown in
the graph at the point where the level suddenly
drops. The photocell level then continues to
increase until around noon. As the daylight
decreases, the area light eventually drops to
near the desired light level. Before reaching this
point, the lights are turned back ON, indicated by
the sudden increase in the photocell level.

Photocellule
1 W, 12/24 V c.c.
N° de cat. ODCØP-S0W
Cette photocellule réagit aux niveaux d’éclairage ambiant dans son champ de vision en envoyant les signaux de sortie correspondants.
Cette commutation s’effectue en fonction du niveau normal programmé.
L’éclairage ambiant peut
provenir de n’importe quelle source de lumière dans le spectre visible. La photocellule ne fait aucune distinction entre la lumière naturelle ou artificielle. Son détecteur a été corrigé sur les plans de la couleur et de l’espace de manière à
capter les modifications d’intensité aussi bien que les yeux humains. La photocellule requiert une alimentation à basse tension de 12/24 V c.c., et consomme un courant d’environ 10 mA. Sa plage de détection se situe entre 0 et 750 pieds-
bougies et sa tension de sortie passe de 0 à 12 ou 24 V c.c. (La sortie est de 0 V c.c. quand l’intensité se situe sous le point de consigne d’exploitation de la lumière ambiante, et de 12 ou de 24 V c.c. quand elle se trouve au-dessus.)
Utilisé avec les blocs d’alimentation de Leviton, ce dispositif peut faire partie d’un système d’exploitation de la lumière ambiante (daylight harvesting). La photocellule mesure l’éclairage ambiant dans un cône renversé de 60° (figure 1). Cet
éclairage inclut la lumière réfléchie au plafond par les murs, les planchers et l’ameublement de la pièce contrôlée. REMARQUE : il faut choisir l’emplacement de ce dispositif avec soin. Le cas échéant, on recommande qu’il soit installé
directement au-dessus des aires de travail, comme les bureaux, les tables de conférence ou les postes informatiques. L’endroit choisi est important, puisque l’éclairage ambiant diffère d’un coin à l’autre de la pièce, suivant l’emplacement
des fenêtres et des luminaires, la couleur des murs, etc. L’intensité lumineuse peut en effet être beaucoup plus faible près de la porte qu’à proximité d’une fenêtre, dans un coin de la pièce ou, particulièrement, à l’égalité du plafond. C’est
pourquoi il faut installé le dispositif de manière à ce qu’il mesure l’éclairage au niveau d’une éventuelle aire de travail.
