Product Description

CL20-8L8 Infrared Safety Light Curtain Sensor with Blanking Function for industry Door

JUTAI IP67 Blanking Safety Light Curtain CL20 - 8L8 Product Description

I. Introduction
The JUTAI safety light curtain CL20 - 8L8 functions by creating a light beam between the emitter and receiver, forming a protective shield. If an object or person enters the grid area, the light beam is interrupted, immediately triggering the safety system to take appropriate measures. Commonly installed at crucial points of devices like doors, automatic doors, lifting equipment, etc., it can promptly detect potential crushing hazards. Widely used in industrial and commercial environments, it is an essential part of automation systems, especially in situations requiring high safety standards.

II. Blanking Mode
The safety light curtain is installed within the door gap. When the door closes normally, the light beams of the light curtain are sequentially blocked from top to bottom. This sequential blocking is recognized by the system as a normal door closing action. If an object passes beneath and blocks the light beam when the door is in the process of closing, the door will open immediately.

III. Normal Mode
Installed on the inside and outside of the door. When the door is closed, the light beams do not pass through. In this mode, regardless of which light beam of the light curtain is blocked, the system will instantly output the door opening signal.

Troubleshooting	Fault Symptoms	Solutions
Slow Flashing Lights After Power On	The emitter and receiver are not aligned.	Readjust the alignment.
Red Light Flashing Fast (Transmitter End)	Voltage at the transmitter end is below 9V or above 28V, causing the red light to flash.	Check and adjust voltage.
Light Curtain Is Normal, But The Door Has No Anti - pinch Action	Wiring error.	Check and correct wiring.
Unable To Enter Concealment Mode	1. Light leakage occurs during the descent of the door, causing discontinuous blocking of the light beam. 2. The bottommost beam is blocked. 3. The lower door or obstruction does not meet the minimum distance required for continuous blocking.	Identify and address the specific issue causing the problem.

Caveat:

Keep the connecting cables away from high voltage or high current conductors.
Ensure that the lower door or obstructive object used for concealment meets the minimum distance required for continuous blocking.
Wipe the windows of the emitter and receiver with a dry, soft cloth to prevent dirt from affecting normal operation.
Do not bend or twist the light curtain.
Avoid direct exposure of sunlight or other infrared light sources to the receiver.
Avoid scratching the surface of the infrared lenses.
