Troubleshooting - LEGRAND Wattstopper PW-203 Installation Instructions Manual

Sensor Light Level Adjustment
The light level can be set with loads ON or OFF. The light level feature operates as a Hold OFF function, meaning that once the light
level in a room reaches a set point the lights will not turn ON until the light level drops below the set point. In order to achieve the
maximum energy savings that the light level feature offers, pick a time during the day when there is enough ambient light in the room to
perform the necessary tasks without the aid of artificial light. In order to set this as the threshold level of brightness so that the artificial
lights remain OFF, perform the following steps:
1. Make sure the room is lit appropriately.
2. Put the sensor into TEST mode using the Time Delay DIP Switches.
3. Press and hold the ON/OFF button (Relay 1 button on the PW-203) for 3 seconds, until you hear a beep.
4. Step away from the sensor. After 25 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-203, light level control only affects Relay 2.
5. Set the Time Delay DIP Switches to the desired delay time.
To Disable Light Level Control
Press and hold the Relay 1 button for 7 seconds, until a double beep sounds.
Reset
Use the DIP Switch Settings Table to return features to factory settings. To reset the PW, 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).
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 the correct On Mode is selected in DIP switches 8 and 9.
• 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.
2. 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.
• Verify the ground connection.
• Make sure line and load are not reversed.
• Confirm 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 (e.g., 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 lit 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 re-setting the Time Delay switches does not clear the LED call technical support.
Wattstopper PW series wall switches fit behind industry standard decorator-style switch cover plates. Cover plates are not included.
Units come in the following colors, which are indicated by the final suffix of the catalog number (shown here in parentheses):
White (-W), Light Almond (-LA), Ivory (-I), Grey (-G), Black (-B).
