Leviton OSFHU-ITW User manual

FEATURES
DESCRIPTION
Leviton's High Bay Occupancy Sensors, Cat. No. OSFHU-ITW and OSFHU-CTW (cold storage), are specifically designed for high mounted areas such as warehouses, manufacturing and other high ceiling applications. The OSFHU-xTW installs directly to an
industrial luminaire or an electrical junction box. It is a self-contained sensor and relay that detects motion using the passive infrared (PIR) to sense sources (such as a person entering a room) within its field-of-view (monitored space) and automatically switches
lights ON. The controlled lights will remain ON until no motion is detected and the scheduled time-delay has expired. The OSFHU-xTW is supplied with two interchangeable lens rings that allows the user to select between a 360 degree High Bay/Low Bay pattern or
an aisle pattern.
Cat. No. OSFHU-ITW is UL listed, cUL listed and conforms to California Title 24 requirements. The Sensor's High Bay lens is designed for 20 ft. to 40 ft. mounting heights for a symmetrical pattern which will provide coverage of 50' to 60' diameter (refer to Figure
4 and 5). The Low Bay lens is designed for 8 ft. to 25 ft. mounting heights for a symmetrical pattern which will provide coverage of 30' to 50' diameter (refer to Figure 6). The Sensor is sensitive to the heat emitted by the human body. In order to initially trigger the
Sensor, the source of heat must move from one zone of detection to another.
Note that occupancy sensors respond to rapid changes in temperature, so care should be taken not to mount the device near a climate control source (i.e. radiators, air exchanges, and air conditioners). Hot or cold drafts will look like body motion to the device and
will trigger it if the unit is mounted too close. It is recommended to mount the Occupancy Sensor at least 6 ft. away from the heating or cooling ventilation source.
INSTALLATION INSTRUCTIONS
WARNING: TO AVOID FIRE, SHOCK, OR DEATH: TURN OFF POWER AT CIRCUIT BREAKER OR FUSE AND TEST THAT THE POWER IS OFF BEFORE WIRING!
WARNING: TO BE INSTALLED AND/OR USED IN ACCORDANCE WITH APPROPRIATE ELECTRICAL CODES AND REGULATIONS.
WARNING: IF YOU ARE NOT SURE ABOUT ANY PART OF THESE INSTRUCTIONS, CONSULT AN ELECTRICIAN.
WARNING: CONTROLLING A LOAD IN EXCESS OF THE SPECIFIED RATINGS WILL DAMAGE THE UNIT AND POSE RISK OF FIRE, ELECTRIC SHOCK, PERSONAL INJURY OR DEATH. CHECK YOUR LOAD RATINGS TO DETERMINE THE UNIT’S
SUITABILITY FOR YOUR APPLICATION.
OTHER CAUTIONS AND NOTES:
1. DISCONNECT POWER WHEN SERVICING LUMINAIRE OR CHANGING BULBS.
2. USE THIS DEVICE ONLY WITH COPPER OR COPPER CLAD WIRE.
3. DO NOT ATTEMPT TO DISASSEMBLE OR REPAIR. CLEAN OUTER SURFACE WITH A DAMP CLOTH ONLY.
TO INSTALL:
NOTE: The OSFHU-xTW is supplied with two lens trim rings. The 360 degree High Bay lens (white color trim ring) is installed at the factory with the Low Bay lens (blue color trim ring) in the carton. Choose the correct lens for your fixture height location and add the
black aisle mask if desiring to block detection outside of the aisle. See below for changing lens trim ring. The OSFHU-xTW Sensor mounts in a 1/2" knock out hole on the end of a luminaire or an electrical box. The Sensor’s field-of-view may be partially obstructed
by the luminaire housing (refer to Figure 1A). At higher mounting heights, the outer beams are not used. As long as the bottom of the sensor is mounted within 1" from the bottom of the luminaire, the field-of-view will not be affected (refer to Figure 1B).
ADAPTER NOTE: For deep bodied luminaires or to clear other obstructions use Leviton's OSFOA-00W Adapter (refer to Figure 2A). The Adapter is designed to provide multiple mounting positions to accommodate different mounting heights for optimum sensor
positioning (refer to Figure 2B). Provided is a keyed, threaded snap-in nipple that holds the Adapter in place while tightening the provided lock-nut. If the Adapter is needed, go to ADAPTER INSTALLATION section. The OSFLO is a single height position adapter
with a quick install snap in fitting without a lock nut (refer to Figure 2B).
SENSOR INSTALLATION:
1. WARNING: TO AVOID FIRE, SHOCK, OR DEATH: TURN OFF POWER AT CIRCUIT BREAKER OR FUSE AND TEST THAT THE POWER IS OFF BEFORE WIRING!
2. The sensor comes with two lens rings, a white one for 360 degree High Bay detection (installed at factory), and a blue one for Low Bay applications.
NOTE: Masking is provided to customize your detection area. Aisle mask can be inserted inside the lens and an optional peel and stick masking kit is included. This circular white adhesive label (with removable wedges) is applied to the OUTSIDE of the sensor lens.
Use any number of wedges to alter field-of-view for your desired application.
3. To change lens, turn trim ring so that the two indented dots line up and pull out by the finger tabs (refer to Figure 7A).
4. Remove the lock-nut from the threaded nipple and insert the wires and the threaded nipple into a half inch hole of the luminaire body or the electrical box.
5. Slide the lock-nut over the wires and thread clockwise on to the threaded nipple to secure the sensor firmly in place making sure the lens is orientated towards the area to be monitored (field-of-view). TIGHTEN to 4 ft-lbs of torque. NEVER USE MORE
THAN 5 ft-lbs of torque (refer to Figure 3).
6. Connect wires per Wiring Diagram as follows: BLACK lead to LINE (Hot); RED lead to LOAD; WHITE lead to LINE (Neutral). Twist strands of each lead tightly and, with circuit conductors, push firmly into the appropriate wire connector. Screw connector on
clockwise making sure that no bare wire shows below the connector.
7. Restore power at circuit breaker or fuse.
NOTE: Allow approximately 1 minute for charge-up. If the lights turn ON and the LED blinks when a hand is waved in front of the lens, then the Sensor was installed properly. If the operation is different, refer to the Troubleshooting Section.
The Sensor is factory preset to work without any adjustments. If you desire to change the factory settings, refer to the SETTINGS section.
OSFOA ADAPTER INSTALLATION:
1. Position one half of the Adapter body on the end of the luminaire to determine the appropriate mounting hole to be used on the Adapter that will position the sensor for optimum coverage. The bottom of the sensor should be at or below the luminaire body (refer
to Figure 2B).
2. Punch out the keyed hole of the Adapter half body to be mounted on the luminaire or electrical box (refer to Figure 1B).
3. Thread the provided lock nut part way on the keyed threaded nipple and insert through the keyed hole from the inside of the Adapter half body and snap into the half inch hole of the luminaire or electrical box and tighten (refer to Figure 2A).
4. Punch out the non-keyed hole on the other Adapter body half and insert the wires and threaded nipple of the Sensor into the hole. Thread the provided lock nut on the nipple and tighten positioning sensor towards the area to be monitored (refer to Figure 2A).
5. Feed the sensor wires through the keyed nipple attached to the luminaire or electrical box and connect per Wiring Diagram as follows: BLACK lead to LINE (Hot); RED lead
to LOAD; WHITE lead to LINE (Neutral). Twist strands of each lead tightly and, with
circuit conductors, push firmly into the appropriate wire connector. Screw connector on clockwise making sure that no bare wire shows below the connector.
6. After wiring connections are completed, snap the two Adapter body halves together.
NOTE: To open the Adapter, use a small, flat blade screw driver and carefully insert into slots and push tabs down while pulling the two halves apart.
7. Restore power at circuit breaker or fuse.
NOTE: Allow approximately 1 minute for charge-up. If the lights turn ON and the LED blinks when a hand is waved in front of the lens, then the Sensor was installed properly. If the operation is different, refer to the Troubleshooting Section.
