Adjusting the Light Level
This feature is factory set at maximum, so that even the brightest light will not
prevent the sensor from turning the load ON when it detects occupancy. If this
feature is not needed, leave the light level at maximum, fully clockwise.
1. The light level must be adjusted when lights would normally be turned OFF
because there is enough natural illumination.
2. Set the sensor to Mode 2 and reduce the time delay to 15 seconds.
3. Adjust the light level to minimum. Let the sensor time out so lights are OFF
and then wait 30 seconds more.
4. Without casting a shadow on the sensor, enter the area. The lights should
remain OFF.
5. Adjust the light level trimpot clockwise in small increments. Wait 5-10 seconds
after each adjustment to see if the lights turn ON. Continue this procedure
until the lights turn ON. At this setting the lights will not turn ON automatically
with occupancy if the light level is above the current natural illumination.
6. Reset the time delay to the desired setting.
Warning: Do not overturn the light level adjustment trimpot!
TEST MODE
To test the detection coverage:
During the TEST mode, the controlled load turns ON for 5 seconds each time the
sensor detects occupancy.
1. Press and hold the ON/OFF button. After 10 seconds the lighted switch
fl ashes. The load turns ON if it was not already ON. The sensor is now in
a TEST mode that lasts 5 minutes. (You can end the TEST mode sooner by
pressing the ON/OFF button for another 10 seconds).
2. Move out of the coverage area or stand very still. The controlled load turns OFF
after 5 seconds if no motion is detected.
3. Move into the coverage area. The controlled load turns ON for 5 seconds
each time the sensor detects motion. After 5 seconds expire without motion
detection, the load turns OFF. The controlled load turns ON automatically with
the next motion detection and stays on for 5 seconds.
4. Repeat as necessary to ensure that the desired coverage areas are within
detection range.
TROUBLESHOOTING
Lighted switch is OFF, no load response to ON/OFF button press:
• Make certain that the circuit breaker is on and functioning.
Lighted switch is ON, no load response to ON/OFF button press:
• Check the light bulb and/or motor switch on the fan mechanism.
Load will not turn ON automatically when the area is occupied and the
sensor is in Mode 2 (lighted switch is ON):
• Press ON/OFF button. If the load turns ON, check the light level setting and
also make sure the sensor lens is not blocked. The light level can prevent the
sensor from turning on the load automatically.
• If the load does not turn ON when you press the ON/OFF button, check the light
bulb and/or motor switch on the fan mechanism.
Load will not turn OFF automatically:
• Press ON/OFF button. If the controlled load turns OFF, go to next step.
• The time delay can be set from 30 seconds to 30 minutes. Ensure that there is
no movement within the sensor’s view for the set time period. Hot air currents
and heat radiant devices can cause false detection. Make sure the sensor is at
least 6 feet (2 meters) away from devices that are a signifi cant heat source (e.g.
heater, heater vent, high wattage light bulb).
If load does not respond properly after following troubleshooting, turn OFF
power to the circuit then check wire connections or call technical support.
