TROUBLESHOOTING

Lights do not turn on with occupancy, and the following condition exists:
LED does NOT flash:
When power is initially applied to the sensor, there is a warm-up period of up to
60 seconds before the LED is active.
1. Check that the circuit breaker has been turned back on.
2. Check the Sensitivity settings. Increase (clockwise) as needed.
3. Check all sensor and power pack wire connections.
4. Check for 24VDC at sensor (violet and green or gray wires).
• If 24VDC is present, replace the sensor.
• If 24VDC is not present, check that high voltage is present to power pack.
If it is, replace power pack.
LED does flash:
1. Check all sensor and power pack wire connections.
2. Check for 24VDC at the power pack's blue wire connection to sensor while
someone moves in front of sensor to activate the LED. If there is no voltage,
replace the sensor. If there is voltage, replace the power pack.
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" next
page).
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:
4. Reconnect the blue wire.
5. 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).
Turn power off at the circuit breaker
before working with or near high voltage.
