SENSOR ADJUSTMENT
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. If desired, set the light level using the steps below. The light level values referenced
are approximate and reference 4000K CCT. Variations in color temperature may
affect the actual levels the sensor sees. It is recommended that light level hold off be set up in
the morning for best results. [If this feature is not needed, leave the light level at maximum (fully
clockwise)].
a. Set the Time Delay to the “walk test” position (fully counterclockwise).
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. If you are unable to find the
ON
position, your space may be
below 100fc. In this case, start your set point below 50%. Typically, most applications would
require 100 or more foot candles.
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 to 30 minutes in 5-minute increments.
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.
• If light level feature is desired, follow the steps from the
Sensor Adjustment
.
• If light level feature is not desired, turn trimpot fully clockwise to disable.
• If load still does not turn
ON
, call 800.879.8585 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. 879.8585 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.
