4. Operasie

The K4021C photocontrol operates automatically based on ambient light levels:

• Activation ON (at Dusk): The photocontrol will turn the connected lighting fixture ON when the ambient light level drops to approximately 1-5 footcandles.
• Activation OFF (at Dawn): The photocontrol will turn the connected lighting fixture OFF when the ambient light level rises to approximately 3-15 footcandles.

4.1 Delay Feature

This photocontrol incorporates a delay feature to prevent unwanted ON/OFF switching due to transient light changes, such as car headlights, lightning, or other temporary light sources. This ensures stable and reliable operation of your lighting system.

5. Onderhoud

The Intermatic K4021C photocontrol is designed for maintenance-free operation. However, periodic inspection is recommended to ensure optimal performance:

• Keep the photocontrol's sensor lens clean and free from dirt, dust, or obstructions that could interfere with light sensing.
• Periodically check wiring connections for tightness and signs of corrosion.
• Ensure the photocontrol is securely mounted and not loose.
