Setup and Installation
Follow these steps to properly install your photo control:
- Power Disconnection: Before beginning any installation, turn off the power to the lighting fixture at the main circuit breaker or fuse box. Confirm that the power is off using a voltage tester.
- Locate Receptacle: Identify the twist-lock receptacle on your outdoor lighting fixture. This is typically a standard 3-prong receptacle designed for photo controls.
- Align Control: Align the three prongs of the Westek LC120BC-4 photo control with the corresponding slots in the fixture's twist-lock receptacle. The control features arrows labeled "INSTALL" and "REMOVE" to guide alignment.
- Insert and Twist: Gently push the photo control into the receptacle. Once seated, twist the control clockwise until it locks securely into place. The "INSTALL" arrow indicates the direction for locking. Ensure a firm connection to maintain weather resistance.
- Restore Power: Once the photo control is securely installed, restore power to the lighting fixture at the circuit breaker or fuse box.

Operating Instructions
The Westek LC120BC-4 Photo Control operates automatically based on ambient light conditions:
- Automatic Operation: The integrated photocell detects when natural light levels fall below a certain threshold (dusk) and automatically activates the connected lighting fixture. When natural light levels rise above the threshold (dawn), the control deactivates the lighting.
- Time Delay Feature: This control includes a time delay feature. This prevents the light from turning on or off due to momentary light changes, such as car headlights or lightning flashes, thereby eliminating annoying flickering.
- Placement Considerations: For optimal performance, ensure the photocell is not obstructed by objects, shadows, or artificial light sources (e.g., other lamps, security lights) that could interfere with its ability to accurately detect natural light.

Maintenance
The Westek LC120BC-4 Photo Control is designed for minimal maintenance. Follow these guidelines to ensure continued reliable operation:
- Cleaning: Periodically inspect the clear housing of the photo control for dirt, dust, or debris that may accumulate and obstruct the photocell. Gently wipe the surface with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Environmental Conditions: The hermetically encapsulated photocell is designed to withstand extreme temperatures ranging from -50°F to +150°F (-45°C to +65°C). No special environmental adjustments are typically required within this range.
- Weather Resistance: The twist-lock design provides weather resistance. Ensure the control remains securely twisted into its receptacle to prevent moisture ingress.
- Inspection: Annually inspect the control for any signs of physical damage or wear. If damage is observed, disconnect power and replace the unit.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Light stays on during the day. | Photocell is obstructed or receiving insufficient light. | Check for obstructions (e.g., leaves, dirt, shadows) covering the photocell. Ensure no artificial light sources are shining directly onto the photocell. |
| Light does not turn on at night. | No power to the fixture, faulty bulb, or faulty photo control. | Verify power at the circuit breaker. Check if the light bulb is working. If power and bulb are fine, the photo control may be faulty and require replacement. |
| Light flickers or cycles on/off rapidly. | Intermittent light source affecting the photocell. | Ensure no other light sources (e.g., car headlights, security lights, streetlights) are intermittently shining on the photocell. The built-in time delay should mitigate minor instances. |
| Control is loose in the receptacle. | Not twisted securely. | Disconnect power, then re-insert and twist the control clockwise until it is firmly locked into the receptacle. |
