Operating Instructions

The Westek CL11LC operates automatically based on ambient light conditions:

Automatic On: When the surrounding light level drops to a certain threshold (dusk), the device will automatically supply power to the connected lamp, turning it on.
Automatic Off: When the surrounding light level increases (dawn), the device will automatically cut power to the connected lamp, turning it off.
Sensor Placement: For optimal performance, ensure the photoelectric sensor on the front of the unit is not covered or obstructed. Avoid placing the unit in areas with inconsistent light, such as under a direct light source or in deep shadow during the day.
Bulb Type: This unit is designed for use with incandescent bulbs up to 300 watts. While some LED bulbs may work, performance can vary, and flickering or improper operation may occur with certain LED types.

Maintenance

To ensure the longevity and proper function of your Westek CL11LC Light Control, follow these maintenance guidelines:

Cleaning: Periodically wipe the device with a soft, dry cloth to remove dust. Ensure the light sensor remains clean and free of debris for accurate operation. Do not use liquid cleaners.
Sensor Obstruction: Regularly check that the photoelectric sensor is not blocked by objects, dust, or dirt, which could affect its ability to detect light levels correctly.
Storage: If storing the device, keep it in a cool, dry place away from direct sunlight and extreme temperatures.

Troubleshooting

Problem	Possible Cause	Solution
Light does not turn on at dusk.	Sensor is obstructed or dirty. Insufficient darkness detected. Lamp or bulb is faulty. Device is not receiving power.	Clean the sensor and ensure it is not blocked. Relocate the device to an area that gets darker at dusk. Test the lamp and bulb in a different outlet. Check the wall outlet for power.
Light does not turn off at dawn.	Sensor is obstructed or dirty. Too much artificial light near the sensor. Insufficient light detected (e.g., in a very dark room).	Clean the sensor and ensure it is not blocked. Relocate the device away from other light sources. Ensure the sensor is exposed to natural daylight.
Light flickers or dims unexpectedly.	Incompatible LED bulb. Sensor is detecting fluctuating light levels (e.g., from a nearby TV or another light source).	Use an incandescent bulb as recommended. Relocate the device to an area with more stable light conditions.
Device feels warm.	Overloaded circuit. Faulty device.	Ensure the connected lamp does not exceed 300 watts. Unplug immediately and discontinue use. Contact customer support.
