Lights do not turn off automatically
1. The sensor may be experiencing activations from outside the controlled area or
from some type of interference (see "Unwanted Sensor Activations" below).
2. Check all sensor wire connections.
3. Disconnect power pack's blue wire:
If the lights do not turn off, replace power pack. Reconnect blue wire.
If the lights turn off, the problem may be in the sensor–to check:
Reconnect the blue wire.
Turn sensitivity and time delay to minimum and allow the sensor to time out.
If the lights turn off, the sensor is working properly (see number 1, above, and
"Sensor Adjustment" for readjustment of sensor).
4. Set sensitivity and time delay to minimum and allow the sensor to time out.
If the lights turn off, the sensor is working properly (see number 1, above, and
"Sensor Adjustment" for readjustment of sensor).
Unwanted Sensor Activations (LED flashes):
• Possible causes
1. The ultrasonic sensitivity may be too high causing detection outside of desired
coverage area.
2. Sensor located too close to HVAC or VAV vents with heavy air flow.
3. If LED is flashing rapidly (~10Hz), an overload condition exists. When this is
corrected, the sensor will return to normal operation.
4. Check if Light Level is enabled.
• If occupancy indicator LED blinks every few seconds, sensor is using Light
Level feature.
• If Light Level functionality is not desired, press and hold for 5 seconds to
return sensor to the default setting (maximum).
• Possible solutions
1. Reduce the ultrasonic sensitivity (counterclockwise) as needed (see "Sensor
Adjustment").
2. Relocate the sensor.
3. Check the blue wire connection. If necessary, replace the power pack.
