• Model Number: PTDSW301
• Specifications: The PTDSW Dual Technology Wall Switch sensors combine advanced passive infrared (PIR) and ultrasonic technologies into one unit. The combined technologies help to eliminate false triggering even in difficult applications. The sensors also contain a light level sensor that holds the load OFF until light levels drop, even if the area is occupied.

Product Usage Instructions

Turning Load(s) ON (ON Mode)

The relay is programmed 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 the relay is manually turned OFF, the PTDSW holds the lights OFF until no motion has been detected for the duration of the Time Delay. With subsequent occupancy, the PTDSW turns the load ON.

Time Delays

The PTDSW sensor holds the load ON until no motion is detected for the selected time delay. Select the time delay using the DIP switch settings.

Test/20 min (DIP 1, 2, OFF)

A Test Mode with a short time delay of five seconds is set when DIP switches 1 & 2 are OFF. It cancels automatically after ten minutes, or when you set a fixed time delay. When the Test Mode times out, the sensor will assume a 20-minute time delay. To restart Test Mode, change the time delay setting to any fixed amount and then return it to the Test setting.

Time Delay (15 min. DIP 1 ON & 2 OFF)

Time delays of 5, 15, or 30 minutes are available. The default is a 15-minute delay.

Walk-Through Mode

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 and then immediately exiting.

PIR Sensitivity Adjustment

The PTDSW 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.

DESCRIPTION AND OPERATION

The PTDSW Dual Technology Wall Switch sensors combine advanced passive infrared (PIR) and ultrasonic technologies into one unit. The combined technologies help to eliminate false triggering even in difficult applications.

Selectable operating modes allow the sensor to turn a load ON, and hold it ON as long as either or both technologies detect occupancy. The sensor detects occupancy and will turn ON all the lights that are connected to the same circuit. After the room is unoccupied, the sensor that detected occupancy turns OFF all the lights once the time delay has expired. The occupant can turn OFF the load at any time by pressing the ON/ OFF button of the sensor that is connected to the circuit. A “walk-through” mode can turn lights OFF after only 3 minutes if no activity is detected after 30 seconds following an occupancy detection.

PTDSW 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. Users can override this function by pressing the ON/OFF button. See the Light Level Adjustment section.

Turning Load(s) ON (ON Mode):
The relay is programmed 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 the relay is manually turned OFF the PTDSW holds the lights OFF until no motion has been detected for the duration of the Time Delay. With subsequent occupancy, the PTDSW turns the load ON.

Trigger Mode

The PTDSW sensor has four occupancy trigger options, set with DIP Switches 5 and 6. Determine the appropriate option using the Trigger matrix. In the Trigger Mode DIP Switch Setting table, deem the area occupied:

• Both require motion detection by the PIR and the Ultrasonic.
• Either requires motion detection by only one technology.
• PIR requires motion detection by the PIR.

Initial Occupancy:
The method that activates a change from “Standby” (area unoccupied and load OFF) to “Occupied” (area occupied and load may turn ON

Maintain Occupancy:
The method indicates that the area is still occupied and the lights should remain ON

Re-trigger:
In Auto ON Mode, after the load turns off, detection by the selected technology within 5 seconds turns the lights back ON. If the load was configured as Manual ON, the re-trigger time is 30 seconds

COVERAGE PATTERNS

Coverage testing has been performed according to the NEMA WD 7 guideline. For best performance, use in spaces not larger than 18’ x 15’.

PIR Sensor:
The sensor has a two-tiered, multi-cell viewing Fresnel lens with a 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.

Ultrasonic Sensor:
The sensor has two ultrasonic transceivers operating at 40 kHz. Detection sensitivity can be adjusted using the trim pot under the ON/OFF buttons .

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 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 reset or disabled. To disable light level control, press and hold the ON/OFF button for 7 seconds until a double beep tone sounds

Reset to Default:
Use the DIP Switch Settings tables on the previous page to return features to factory settings. To reset the PTDSW, press and hold the ON/OFF 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).

INSTALLATION

WARNING: TURN THE POWER OFF AT THE CIRCUIT BREAKER BEFORE WIRING

1. Make sure that the power has been turned OFF at the circuit breaker.
2. Wire the 3-wire single pole plug tail per the instructions and wiring diagram.
3. Insert plug tail into the PTDSW device and verify snap engagement.
4. Connect white wire to neutral wire from the panel box using included wire nut.
5. 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 them.
6. Turn the circuit breaker ON. WAIT ONE MINUTE, then push the ON/OFF button and the lights will turn ON. There is a delay due to the initial power-up of the sensor that only occurs during installation. If the device fails to start, verify line and load are wired to the plug tail per the diagram. Line and Load are marked on the plug tail.
7. Test and adjust the sensor if necessary.
8. Installindustry-standardd decorator wall switch cover plate (not included).

DIP SWITCH SETTINGS

TROUBLESHOOTING

1. Press and release the ON/OFF 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.
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 1.877.BY.LEGRAND for technical support.

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

1. Press and release the ON/OFF button to make sure that the correct lights come ON for each relay. If the lights turn ON, set PIR and Ultrasonic Sensitivity to High.
2. Check the wire connections, in particular, the Neutral, Lin,e and Ground connections. Verify that connections are tightly secured.
3. If lights still do not turn ON, call 1.877.BY.LEGRAND 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 and 2 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 ahigh-wattagee light bulb) mounted near the sensor.
3. If the lights still do not turn OFF, call 1.877.BY.LEGRAND 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 coverageareasa.
3. Adjust the Ultrasonic Sensitivity. Rotate the trimpot counterclockwise to reduce sensitivity

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

1. Check the Ultrasonic trimpot. If it is set at fully counter-clockwise (MIN) the unit is in Service Mode. Set the trumpet to a mid-range position.
2. If resetting the Time Delay switches does not set the sensor features, call technical support
