Legrand WSP-250 - Manual

TROUBLESHOOTING
Load will not turn on:
• LED does not flash:
‑ Check the sensitivity for proper configuration.
‑ Check all wire connections. Verify the ground wire is tightly secured.
• LED does flash:
‑ Press the ON/OFF button. If load does not turn on, check all wire
connections and verify the load wire is tightly secured.
‑ Check the light level trimpot. Turn it fully clockwise
• If load still does not turn on, call 800.223.4185 for technical support.
Load will not turn off:
• The time delay can be set for 30 seconds
(Walk Test), 5, 10, 15, 20, 25, or 30 minutes.
Ensure that the time delay is set to the
desired delay and that there is no movement
within the sensor’s view for that time period.
• To quickly test the unit for proper operation,
turn the time delay to minimum (fully
counterclockwise) and move out of the
sensor’s view. Load should turn off after
30 seconds.
• If load still does not turn off, call
800.223.4185 for technical support.
Sensing motion outside desired area:
• Opaque adhesive tape is included with the
sensor and can be used to limit the detection areas. See Masking the Lens.
• Adjust sensitivity counterclockwise to reduce excessive sensitivity.

dO NOT OVERTURN TRImPOTS WHEN adjUSTING THE SENSOR!
1. To test unit operation, press the ON/OFF button to turn the load on.
2. Remove the button cover to access the adjustment controls. Use a small,
flat blade screwdriver to press down the locking tab at the top of the button,
then gently pry it off.
a) Set the time delay to the “walk test” position (fully counterclockwise).
b) Leave the room. The load should go off after 30 seconds.
3. To test sensitivity:
a) Make no motion for 3 seconds.
b) Wave your hand sideways in front of the sensor at a distance of
approximately 12". The LED blinks when movement is detected.
Typically, the sensitivity should be at maximum (fully clockwise).
4. Set the light level when the controlled light would normally be turned off
due to the presence of sufficient daylight or other electric light. [If this
feature is not needed, leave the light level at maximum (fully clockwise)].
a) Set the Time Delay to at least 5 minutes. This takes the sensor out of
Walk‑test mode, and enables the light level feature.
b) Set the Light level to 50% (12 o’clock position) which is approximately
100fc. Let the sensor time out so lights are off. Enter the space and
lights should remain off.
c) Make sure your body does not cast a shadow on the sensor, and adjust
the light level trimpot clockwise in small increments.
d) After each adjustment, wait 5‑10 seconds to see if the lights turn on.
Repeat until the lights turn on. At this setting the load connected to the
sensor will not turn on if light levels are above the current illumination.
Note: Users can override this function by placing their hand in front of the
sensor to block incoming light. The load will then remain on until the
space is unoccupied or the light level rises above the setpoint and the
time delay expires.
5. Reset the time delay to the
desired setting. The time delay
can be set from 30 seconds
(see Walk‑test feature, light
level feature is disabled)
to 30 minutes in 5‑minute
increments.
