legrand PW-302 Occupancy Sensor Passive Infrared PIR Instruction Manual

SPECIFICATIONS

DESCRIPTION AND OPERATION

The PW Passive Infrared Wall Switch sensors use advanced passive infrared (PIR) technology.
PW sensors have Multi-Way available on all models. A “Walk-Through” mode can turn lights OFF after only 3 minutes, if no activity is detected after 30 seconds following an occupancy detection.
The PW-301 has one relay and one ON/OFF button. The PW-302 contains two relays and two ON/OFF buttons to allow control of one or two loads independently. Pressing a button toggles the state of the corresponding relay.
PW sensors contain a light level sensor. If adequate daylight is present, the sensor holds the load OFF until light levels drop, even if the area is occupied. In the PW-302, light level only affects the load on Relay 2. Users can overrule the hold OFF function by pressing the ON/OFF button. See the Light Level Adjustment section.

Turning Load(s) ON (ON Mode)
The relays are programmed independently for either Auto ON or Manual ON. In either mode, the load can be turned ON or OFF using the ON/OFF button.

Presentation Mode
Presentation Mode is a feature of the Auto ON mode.When both relays are manually turned OFF the PW holds the lights OFF until no motion has been detected for the duration of the Time Delay. With subsequent occupancy, the PW turns the load ON. If both relays are ON and one relay is manually turned OFF this relay remains OFF until both the Time Delay and retrigger delay expires for the relay that is ON, after that time the ON Mode control settings again apply.

Time Delays
The PW sensor holds the load ON until no motion is detected for the selected time delay. Select the time delay using DIP switch settings. In the PW-302, both relays use the same delay. See DIP SWITCH SETTINGS for more information.

Walk-Through
The Walk-Through mode shortens the time delay to reduce the amount of time the load is ON after a brief moment of occupancy, such as returning to an office to pick up a forgotten item then immediately exiting.

PIR Sensitivity Adjustment
The PW sensor constantly monitors the controlled environment and automatically adjusts the PIR to avoid common ambient conditions that can cause false detections, while providing maximum coverage.

Alerts
The PW can provide audible and/or visible alerts as a warning before the load turns OFF.

ADJUSTMENTS

Sensor Adjustment
Remove the wall plate. Remove the button cap by firmly squeezing together the top sides of the button assembly. Gently pull it away from the unit. When the adjustments are completed, replace the button cap by inserting its hinges into the tabs on the main unit, and then squeeze the top of the button while pressing it into the unit. Reinstall the cover plate.

Light Level Adjustment
The light level can be set with loads ON or OFF. To enable light level control and set the threshold:

1. Make sure the room is lit appropriately.
2. Put the sensor into TEST Mode (see Time Delay switches). You have 10 minutes to complete the procedure.
3. Press and hold the ON/OFF button (Relay 1 button on the PW-302) for 3 seconds, until you hear a beep.
4. Step away from the sensor. After 10 seconds a beep sounds, indicating that the threshold level is set. This threshold is retained,
   even if power is lost, until it is re-set or disabled. In the PW-302, light level control only affects Relay 2. To disable light level control, press and hold the Relay 1 button for 7 seconds, until a double beep tone sounds.

Reset to Default
Use the DIP Switch Settings tables to return features to factory settings. To reset the PW, press and hold the Relay 1 button for 10 seconds, until a triple beep sounds. This resets the sensor and disables light level control (the brightest ambient light will not hold the light OFF).

COVERAGE PATTERNS

Coverage testing has been performed according to the NEMA WD 7 guideline. For best performance, use in spaces not larger than 15′ x 12′.

PIR Sensor
The sensor has a two-tiered, multi-cell viewing Fresnel lens with 180 degree field of view. The red LED on the sensor flashes when the PIR detects motion.

Masking the lens
Opaque adhesive tape is supplied so that sections of the PIR sensor’s view can be masked. This allows you to eliminate coverage in unwanted areas. Since masking removes bands of coverage, remember to take this into account when troubleshooting coverage problems.

INSTALLATION

1. Make sure that the power has been turned OFF at the circuit breaker.

2. Connect wires to the PW flying leads as shown in the wiring diagram that is appropriate to the PW model and electrical supply. The ground wire (green) must be fastened to ground for the sensor to work properly.
   WARNING: TURN THE POWER OFF AT THE CIRCUIT BREAKER BEFORE WIRING.

3. Attach the sensor to the wall box by inserting screws into the two wide holes on the top and bottom of the attached metal bracket. Match them up with the holes in the wall box and tighten.

4. Turn the circuit breaker ON. Wait one minute, then push the Auto ON/OFF switch for each load and the lights will turn ON. There is a delay due to initial power-up of the sensor that only occurs during installation.

5. Test and adjust the sensor if necessary.

6. Install industry standard decorator wall switch cover plate (not included).

Signal Wire (Blue with White Stripe) connects to Neutral. For a replacement or retrofit application , it can connect to Ground.

MULTI-WAY

The Multi-Way capability is available on all models. Sensors can easily be wired together for convenient control of a common load. When wiring this way, only use 300 series sensors. Multi-Way in 300 series is not compatible with prior sensor models. The following principles apply for Multi-Way:

• All units can see each other’s push button events and respond accordingly.
• All units in the space must be wired using the same connection to the signal wire.
• All units can see each other’s PIR trigger event. The response will be determined by the Light Level setting and/or conditions of the space of the detecting sensor.
• The time delay for all units is defined by the unit with the smallest time delay.

TROUBLESHOOTING

Lights do not turn ON with motion (LED does flash)

1. Press and release each button to make sure that the correct lights come ON for each relay. If the lights do NOT turn ON, check wire connections, especially the Load connection. If the lights turn ON, verify that the correct ON Mode is selected in DIP Switches 8 and 9.
2. Check to see if light level control is enabled: cover the sensor lens with your hand. If the lights come ON, adjust the light level setting.
3. If lights still do not turn ON, call 800.879.8585 for technical support.

Lights do not turn ON with motion (LED does not flash)

1. Press and release each button to make sure that the correct lights come ON for each relay. If the lights turn ON, verify that Sensitivity is on High.
2. Check the wire connections, in particular, the Line connection. Verify that connections are tightly secured.
3. If lights still do not turn ON, call 800.879.8585 for technical support.

Lights do not turn OFF

1. There can be up to a 30 minute time delay after the last motion is detected. To verify proper operation, set DIP Switch 1 to ON, then reset switches 1, 2, and 3 to OFF to start Test Mode. Move out of view of the sensor. The lights should turn OFF in approximately 5 seconds.
2. Verify that the sensor is mounted at least six feet (2 meters) away from any heating/ventilating/air conditioning device that may cause false detection. Verify that there is no significant heat source (such as a high wattage light bulb) mounted near the sensor.
3. If the lights still do not turn OFF, call 800.879.8585 for technical support.

Sensing motion outside desired areas

1. Select PIR Sensitivity ­ Low (DIP switch 5 = ON) if necessary.
2. Mask the PIR sensor’s lens to eliminate unwanted coverage area.

Red LED is OFF all the time and the sensor features don’t work.

1. Check DIP switches 1,2,3. If they are all ON the unit is in Service Mode. Set the DIP switches to a valid Time Delay setting.
2. If resetting the Time Delay switches does not set the sensor features, call technical support.
