TROUBLESHOOTING
For any unexpected operation
1. Check DIP switch settings.
2. Make sure the switches are set according to the defined settings in the
Logic Configuration Chart.
Lights do not turn on with occupancy, and the following condition exists:
• Both LEDs do not flash: (DIP switch #7 must be ON to enable the LEDs)
1. Check that the circuit breaker has been turned back on.
2. Check all sensor wire connections.
3. 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.
• Red LED does not flash:
When power is initially applied to the sensor, there is a warm-up period of 30
seconds before the red LED is active.
1. Make sure that PIR Sensitivity is set to 100% (DIP switch #8 set to on).
2. If it still does not flash, call 800.879.8585 for Technical Support.
• Green LED does not flash:
1. The Ultrasonic Sensitivity setting may need to be increased.
Turn clockwise as needed.
• Both LEDs flash:
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 area around the green 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.
3. Check for line voltage input to the sensor.
Lights do not turn off automatically:
Call 800.879.8585 for Technical Support
WARNING
TURN POWER OFF AT THE CIRCUIT BREAKER
BEFORE WORKING WITH OR NEAR HIGH VOLTAGE.
