In modern chemical plants, people work together with mechanical equipment. Mechanical equipment is becoming more and more automatic, and workers are more and more likely to be hurt. It is particularly important to improve the safety of mechanical equipment. So how to determine which level of Safety light curtain we need? Here are some useful suggestions.

1. Determine The Level of Safety Light Curtain

Before using a machine, we must make a risk assessment of the machine. Evaluate the potential hazards associated with each part, and then finally determine the hazard level of the it. According to the European machine safety standard, the hazard level is divided into B, 1, 2, 3, 4. The safety level of the safety light curtain also corresponds to the five levels. Level 4 is the highest safety level, which means the machine is at the most dangerous level. For example, if the danger level of a machine (or a part thereof) is identified as level 4, the corresponding safety light curtain must also be level 4.

Today we are mainly talking about the commonly used light curtain Level 2 (light curtain LV 2) and light curtain level 4 (light curtain LV 4).

1. Light Curtain LV 2

The main features of the light curtain LV2 are: low cost, single CPU and dual safety channel output. It meets the safety requirements in the way of periodic self inspection. A fault may lead to the loss of some function, but it can be detected in the next cycle. The safety light curtain LV2 is generally a protective device used in small occasions or occasions with low risk level. It can also be used in general automatic production equipment, robot workbench and so on.

2. Light Curtain LV 4

The main features of the safety light curtain LV4 are: dual CPU, dual safety channel output, reliable control and superior performance. It uses guaranteed safety devices and technology. failure will not lead to the loss of machine function. And it will continue to conduct self-test. light curtain LV4 is generally applied to severely dangerous occasions or high-risk equipment, or other places where it is clearly required by local regulations.

4. Benefits of Installing Safety Light Curtain on Hazardous Equipment

For workers: Protect the safety and enhance the sense of safety of workers.
For enterprises: 1. Safety production environment; 2. Reduce the pressure of safety responsibility of the management; 3. Meet customer requirements and qualification identification; 4. Improve technical level and enhance competitiveness; 5. Reduce the cost of litigation and accidents.

At present, punch presses, hydraulic presses, bending machines, film presses, plate shears and injection molding machines in the market must be equipped with safety light curtains. Industrial manipulators, packaging equipment, production lines, home appliance and other automatic equipment can also use safety light curtain for better safety protection!
