Sensor Placement - LEGRAND Wattstopper W-500A Manual De Instrucciones

When positioning the sensor make sure the receiver is aimed away from nearest wall and toward the area to be covered. On the
W-500A model, there is only one receiver, which is on the opposite side of the by-pass pin.
Always make sure this receiver is pointed toward activity area. The W-1000 and W-2000
both have dual receivers. Point these toward the activity area.
CORRECT LOCATION
For enclosed spaces, place
sensors as shown above.
WARNING: TURN THE POWER OFF AT THE
CIRCUIT BREAKER BEFORE WIRING.
For normal Installation, connect:
• Blue wire from sensor to Blue wire from Power Pack.
• Red wire from sensor to Red wire from Power Pack.
• Black wire from sensor to Black wire from Power Pack.
After the unit is installed, the sensitivity should be adjusted so the lights stay ON whenever the controlled area is occupied. Before
starting the adjustment process, make sure office furniture is installed, lighting circuits are powered up, and HVAC systems are in the
overridden/ON position. VAV systems should be set to their highest airflow.
1. Set the unit sensitivity to low (usually 3 or 4).
2. Set the unit's time delay at it's minimum, usually 15 seconds.
3. Move out of sensor range until the lights turn OFF.
4. Walk into the controlled area. If the lights don't turn on, increase the
sensitivity slightly and try again. Repeat until the lights come ON.
5. It may be necessary to turn the sensitivity up slightly if the lights turn OFF while the room is occupied.
6. For best acceptance and performance, we recommend max. Time delay for normal applications.
