FEATURES OF THE LS20A SEPARATE-SENSOR LIGHT SENSOR SWITCH
The LS20A, also known as a photo sensor, photoelectric switch, or light sensor switch, can detect changes in ambient light. It automatically turns the light ON when it gets dark and turns the light OFF when it becomes bright, providing great convenience. The light level can be adjusted from 10 Lux to 100 Lux.
A special feature of the LS20A is its two-part design: one switch control unit installed inside the electrical cabinet and one separate light sensor head. An additional cable can be connected to place the sensor head in a location where it can receive natural outdoor light.

In addition, the device features a LUX adjustment function, allowing the light activation level to be set according to the surrounding lighting conditions. This light sensor switch can turn lights ON or reduce unnecessary lighting during the daytime when sunlight enters offices, factories, hallways, and more, helping save electricity more effectively.
The LS20A light sensor features a compact design, high light-sensing sensitivity, and is easy to install and use. The switch unit is designed for DIN rail installation, making it suitable for installation inside electrical cabinets and providing better protection against dust and water.
Compact design for easy installation
The light sensor switch can be used in many different areas
More convenient when used for advertising signboard lighting
BENEFITS OF USING A LIGHT SENSOR SWITCH
Helps the electrical system turn ON/OFF appropriately based on ambient light conditions.
Effectively saves electricity when used for public lighting, signboards, factories, homes, and more.
Saves time spent monitoring and switching lights ON/OFF. It allows users to set desired ON/OFF schedules and automatically turn the lights OFF when sunlight appears.
Easy to install and convenient to use, with low power consumption.
Turn off promptly when it's light, overcome the problem of using a timer switch because in the winter it gets dark early and during the season it gets dark late...
Can be used for anti-theft purposes: balcony lights, gate lights, and garden lights automatically turn ON when it gets dark. This may deter intruders because they may think someone is at home.

Nếu người dùng điều chỉnh hướng mũi tên xoay về “sun “thì cảm biến ánh sáng sẽ tự động kích hoạt mở đèn khi trời tối mờ( <100 Lux)
Nếu người dùng điều chỉnh hướng mũi tên xoay về “moon “thì cảm biến ánh sáng sẽ tự động kích hoạt mở đèn khi trời tối hẳn ( <10 Lux)
HOW TO INSTALL AND WIRING:
1.Gắn tủ điện thanh ray
2. Cách đấu dây
ATTENTION:
Turn off the power before installing the device
Teminal N and L Power supply to 220V, Teminal N và L” cấp nguồn ra đèn
Mắt cảm biến quang cố định vị trí nhận ánh sáng mặt trời tốt cho buổi sáng và buổi chiều
Không lắp thiết bị nơi ẩm ướt,nơi có ánh sáng trực tiếp từ đèn chiếu sáng
KIỂM TRA THIẾT BỊ:
Điều chỉnh hướng mũi tên xoay về “moon “ sau đó dùng vải khô hoặc nilông đen che tối mắt cảm biến ánh sáng. Sau 10s giây thì đèn sẽ mở. Dùng nguồn sáng (đèn pin,đèn chiếu sáng) cho mắt cảm biến nhận sau 10s đèn sẽ tắt.
SOME COMMON PROBLEMS AND HOW TO FIX:
The lamp does not work:
Kiểm tra nguồn điện vào đui thiết bị đã có điện chưa?
Kiểm tra lại xem bóng đèn cò vấn đề gì không
Check whether the Lux level at the installation site has dropped to the threshold for turning on the light?
Đèn sáng rồi tắt (không cảm ứng lần 2):
Kiểm tra nút chỉnh đang AUTO hay hẹn giờ.Nếu chế độ hẹn giờ thì phải kích hoạt nguồn sáng vào cảm biến 10s hoặc tắt nguồn rồi mở lại
Đèn chóp – tắt liên tục:
Check if the light from the bulb reflects back to the optical sensor
LS20A còn gọi cảm biến quang, công tắc quang điện hoặc công tắc cảm ứng ánh sáng, có khả năng nhận biết sự biến đổi ánh sáng trong môi trường. Từ đó, tự động mở đèn khi trời tối và tự tắt đèn khi trời sáng vô cùng tiện lợi. Có thể chỉnh được độ sáng từ 10Lux đến 100Lux.
Điểm đặc biết của LS20A này là có thiết kế thành 2 bộ phận, một là bộ điều khiển công tắc nằm trong tủ điện và một là mắt cảm ứng ánh sáng rời, có thể kết nối thêm dây để đưa ra vị trí lấy được ánh sáng tự nhiên ngoài trời.
