TROUBLESHOOTING
CAUTION
Turn power off at the circuit breaker
before working with or near high voltage.
Lights do not turn ON with occupancy, and the following condition exists:
• Red LED does not flash:
1. Check that the circuit breaker has been turned back on.
2. Check all sensor and power pack wire connections.
3. Check for 24V input to the sensor.
- If 24V is present, replace the sensor.
- If 24V is not present, check that high voltage is present to power pack.
If it is, replace power pack.
4. Make sure that PIR Sensitivity is set to minimum (DIP switch #5 set to
on
).
5. If it still does not flash, call 800.879.8585 for Technical Support.
• LED flashes:
1. Check all sensor and power pack wire connections.
2. Check for 24VDC at the power pack’s blue wire connection to
sensor while sensor is activated. If there is no voltage, replace
the sensor. If there is voltage, replace the power pack
3. If LED is 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.
• Line voltage switch connected as shown in wiring example.
1. Make sure switch is set to
ON
position.
Lights do not turn OFF automatically:
1. The sensor technology (PIR) may be experiencing activations
from outside the controlled area or from some type of
interference (see “Unwanted Sensor Activations” below).
2. Check all sensor and power pack 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).
