Troubleshooting; Ordering Information - LEGRAND Wattstopper CX-105 Instrucciones De Instalación

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
• 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").
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:
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).
Unwanted Sensor Activations (LED flashes):
Possible causes
1. Improper sensor location or angle adjustment causing detection outside of desired coverage area.
2. Sensitivity set too high.
3. Sensor located too close to HVAC or VAV vents with heavy air flow.
Possible solutions
1. Mask the lens to reduce PIR coverage (see "Masking the lens", under "Coverage Patterns").
2. Reduce the sensitivity (counterclockwise) as needed (see "Sensor Adjustment").
3. Adjust the sensor angle (see "Sensor Adjustment").
4. Relocate the sensor.
Override:
To override all sensor functions, set DIP switch #5 to on.
The red LED will come on and stay on for the duration of the override.
