TROUBLESHOOTING

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 following condition
exists:
• PIR Activity LED does not flash:
1. Check that the circuit breaker has been turned back on.
2. Check all sensor wire connections.
3. Make sure that the LED is enabled (DIP switch 6 on) and that the
PIR Sensitivity is set for Max/Smartset (DIP switch 7 on).
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.
• PIR Activity LED flashes:
1. If the sensor's Light Level feature has been turned on, the lights
connected to the Light Level Output might be held off because of
the level of ambient light in the controlled area. To test whether
the Light Level adjustment is the problem, cover the PIR lens and
PIR Activity LED (see diagram) with your hand to see if the lights
turn on. If the lights turn on, the Light Level setting was keeping
the lights off (see "Sensor Adjustment" for readjustment).
2. Check all sensor wire connections.
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. 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
"Sensor Adjustment" for readjustment of sensor).
Turn power off at the circuit breaker
before working with or near high voltage.
