JUTAI 1.8m 29 - Beam Safety Blanking Light Curtain Sensor: Unparalleled Safety Solution

I. Introduction

II. Packaging and Included Components

III. Product Functionality

1. Protective Grid Formation
   • By emitting a precisely calibrated beam of light between the transmitter and receiver, it constructs a highly reliable protective grid. This grid acts as a vigilant sentinel, instantly detecting any intrusion by objects or persons into the defined grating area. Once detected, it promptly triggers the safety system, thereby ensuring the safety of personnel and equipment.
   • The unique blanking function sets this sensor apart. It can accurately discriminate and ignore irrelevant objects, guaranteeing that its operation remains unaffected by spurious obstructions. This feature is particularly crucial in complex industrial environments where multiple objects may be present.
2. Versatile Application Scope
   • It finds extensive application in critical safety zones such as doors, automated gates, and elevating equipment. Its ability to accurately detect potential entrapment risks makes it an indispensable safety component in these settings.

IV. Size and Physical Dimensions

1. Optimal Length and Slim Profile
   • With a total length that is ideally suited for a wide variety of installation scenarios, and a sleek cross-section measuring just 12.5mm, it can be effortlessly integrated into most door gaps without impeding the normal closing action of the doors. This design not only ensures a seamless fit but also adds to the overall aesthetics of the installation.
2. Precise Beam Spacing
   • The beam distance is meticulously set at 60mm, endowing the sensor with the remarkable ability to detect even slender objects like forklift forks with exceptional accuracy. This high level of precision is essential for ensuring the safety of both personnel and valuable equipment in industrial settings.

V. Wiring Specifications

1. Receiver Wiring
   • The wiring configuration of the receiver is clearly defined, with each wire color serving a specific function. The black wire is designated for Ground (GGD), the yellow wire for Signal transmission, the red wire for DC12V - 24V Synchronization, and the green and white wires are reserved for future use or specific customizations.
2. Transmitter Wiring
   • Similarly, the transmitter has its own distinct wiring setup. The black wire is for Ground (GND), the yellow wire for Signal, the red wire for DC12V - 24V power supply, and the green and white wires are reserved. It is of utmost importance to correctly connect the yellow wires for both receiving and transmitting to ensure proper communication and functionality.

VI. Technical Parameters

VII. Troubleshooting Guide

1. Light Curtain Misalignment
   • If the light curtains do not align properly, possible solutions include power cycling the receiving and transmitting units, verifying the proper connection of the signal synchronization line, and re-installing the units if their position is unstable.
2. False Signal Detection
   • In the event that the light curtain indicates a received signal when not blocked, check for the presence of other infrared devices in the vicinity that may be causing interference. Additionally, clean the light curtain window to remove any potential obstructions or dirt that could be affecting the signal, and readjust the alignment angle between the transmitter and receiver.
3. Absence of Anti-Pinch Action
   • When the light curtain is functioning normally but the anti-pinch action is not triggered, it is essential to inspect the relay output and the anti-pinch port. Also, ensure that the working distance is within the specified range to guarantee proper operation.
4. Hide Function Inaccessibility
   • If the hide function cannot be accessed, check for any light leakage during operation, verify if the bottom beam is blocked, and ensure that the lower door or shelter meets the minimum distance requirements for continuous shielding.

VIII. Cautions and Maintenance

1. Cable Management
   • Keep all connecting cables away from high voltage or high current conductors to prevent electromagnetic interference and ensure the safe and stable operation of the sensor.
2. Proper Shading Components
   • Ensure that the lower side door or shelter used for the fade feature is appropriate and meets the necessary conditions for optimal performance.
3. Regular Cleaning
   • Periodically wipe the transmitter and receiver windows with a dry soft towel to maintain clear transmission and reception paths. This simple yet crucial maintenance step helps prevent dirt and debris from interfering with the normal operation of the sensor.
4. Physical Handling
   • Avoid bending or twisting the light curtain to preserve its structural integrity and functionality. Any physical damage to the curtain can compromise its performance and safety capabilities.
5. Shading Distance Maintenance
   • Adhere to the specified minimum distance for continuous shading to ensure accurate and reliable detection. Deviating from this distance may result in false detections or reduced performance.
6. Surface Protection
   • Do not scratch the surface cover of the sensor to protect its internal components and maintain its aesthetic appearance. A scratched or damaged surface may also affect the sensor's performance over time.
7. Monthly Inspections
   • Conduct monthly checks for any signs of looseness in the transmitter, receiver, and extension cord. Also, verify the reliability of the grounding wire, power supply wire, and signal output wire to ensure continuous and safe operation.

IX. Special Features

1. Seamless Integration
   • Its innovative design allows for seamless installation in door gaps, without obstructing the normal closing process. This not only simplifies the installation process but also enhances the overall functionality and convenience of the safety system.
2. Sunlight Immunity
   • Rigorously tested and proven to be immune to interference from strong sunlight, the sensor can operate reliably even in bright outdoor or well-lit indoor environments. This feature ensures consistent performance regardless of lighting conditions.
3. Premium Componentry
   • The utilization of imported lamp cores significantly contributes to its exceptional anti-light performance, elevating the overall quality and durability of the product. This ensures long-term reliability and accurate detection in a wide range of applications.
