TROUBLESHOOTING

power off at the cir
For any unexpected operation
1. Check DIP switch settings.
2. Make sure the switches are set according to the defined
settings in the DIP Switch Setting chart.
Lights do not turn on with occupancy, and the LED does not flash:
1. Check that the circuit breaker has been turned back on.
2. The Ultrasonic Sensitivity setting may need to be
increased. Turn clockwise as needed.
3. Check all sensor wire connections.
4. Check for line voltage input to the sensor.
- If line voltage is present, replace the sensor.
- If line voltage is not present, check line wiring.
Lights do not turn off automatically:
1. The sensor may be experiening activations from outside
the controlled area or from some type of interference
(see “Unwanted Sensor Activations” below).
2. Check all sensor wire connections.
3. 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):
1. The ultrasonic sensitivity may be too high causing detection
outside of desired coverage area. Reduce the ultrasonic sensitivity
(counterclockwise) as needed (see “Sensor Adjustment”).
2. Sensor located too close to HVAC or VAV vents
with heavy air flow. Relocate the sensor.

CAUTION
TURN POWER OFF AT THE CIRCUIT BREAKER
BEFORE WORKING WITH OR NEAR HIGH VOLTAGE.
