High Quality Infrared Light Curtain for Security Alarm System

Product DescriptionSafety light curtains are also photoelectric safety protection devices (safety protectors, punch protectors, infrared safety protection devices, etc.). In modern factories, people and machines work together, and they can be installed on some potentially dangerous mechanical equipment to protect workers. Prevent security incidents from happening. For Example, stamping machinery, shearing equipment, metal cutting equipment, automated assembly lines, automated welding lines, mechanical transmission, and handling equipment, and hazardous areas (toxic, high pressure, high temperature, etc.), are likely to cause personal injury to operators, can be installed.1. The unique structural design ensures that there is no blind spot in the entire protection area;2. Dual-channel OSSD output function, which can be cross-monitored with each other;3. The self-diagnosis function can detect the failure circuit module of the light curtain. and issue an alarm signal;4. With interlock reset, external test, and EDM function, strengthen the output monitoring ability;5. Adopt optical communication synchronization, simplify the electrical connection and make the operation easier;6. Meet the requirements of Type 4, SIL3 and PLe safety levels, and can be used for the protection of various parts of the body;7.

In addition, a self-test will be performed periodically (within response time) during the work process.2. Control output(OSSD)waveformWhen the light curtain is in the lighting state( the beams are not blocked), the control output is NO,  while in order to test the output circuit, the Control output will turn to OFF Periodically and the output circuit is diagnosed as normal if the OFF signal was feedback. When the off-pulse signal is not included in the output signal, the output circuit or wiring of the receiver is diagnosed as a fault, and the light curtain immediately enters the locking state.  Product self-inspection steps1. Detect whether the installation position of the object and the proximity sensor has deviated, slacked, or skewed; whether there is slack, poor contact, or disconnection in the wiring and connection parts2. Whether there is adhesion or accumulation of metal dust, etc.3. Is there any abnormality in using temperature conditions and environmental conditions?4. Set whether the flashing of the display lamp type is abnormal.If you must be careful not to disassemble and repair by yourself during the inspection, and to easily find out the fault, you can investigate the operating state of the sensor
