Service Function; Coverage Patterns - LEGRAND Wattstopper WS-301 Mode D'emploi

Walk-test feature
When the Time Delay trimpot is in the fully counterclockwise position, the sensor has a 30 second time delay. This allows you to quickly
check the sensor coverage area.

Service function

In the event of unit failure or if it is necessary to leave the load ON, remove the Service Jumper plug. This disables all automatic ON and
OFF functions and the load can only be operated using the ON/OFF button.

COVERAGE PATTERNS

The WS detects motion in areas up to 900 sq. ft. and up to 35 feet from the sensor. Ideally, the sensor is designed for small amounts of
motion in spaces up to 300 sq. ft. The Fresnel lens on the sensor is a multiple segment viewing lens with a field of view of 180°.
The sensor must have a clear view of the people in the space in order to detect occupancy. Obstructions, such as furniture blocking the
sensor's lens, may prevent occupancy detection.

MASKING THE LENS
Opaque adhesive tape is supplied so that sections of the 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.
