Red and Green LEDs flash
1. Check all sensor and power pack connections.
2. Check if Light Level is enabled.
•
If occupancy indicator LEDs blink together 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).
3. Check for 24VDC at the power pack blue and black wire connections to sensor
while sensor is active.
•
If there is no voltage, replace the sensor.
•
If there is voltage, check for 24VDC between the blue and black wire at the
power pack. If 24VDC is present and the relay is not closing, replace it.
•
If 24VDC is not present, check for a break in the low voltage wiring.
4. If LEDs are flashing rapidly (~10Hz), an overload condition exists. When this
is corrected, the sensor will return to normal operation. Check the blue wire
connection. If necessary, replace the power pack.
Lights do not turn off automatically.
Green LED flashes
Reduce ultrasonic sensitivity by turning adjustment pot counter-clockwise until it
only flashes when movement occurs.
Red LED flashes briefly and Green LED does not flash
Check to see if you have used the Manual Switch connection. Do not connect
anything to this terminal if you are not using a low voltage momentary switch
between the sensor and power pack.
Red LED randomly flashes
Set PIR sensitivity to minimum by turning DIP switch 5 to the “on” position.
Lights do not turn off
1. Check all sensor and power pack wire connections.
2. Disconnect power pack blue wire.
•
If lights do not turn off, check power pack wiring. Replace the power pack
if necessary.
•
If lights turn off, the problem may be the sensor or wiring between the
sensor and power pack.
