What isthis for?

Light curtains are used to detect attempts to access a hazardous area. Under normal operation, if the light curtain detects an object, it causes the safety system to stop any dangerous movement in that area. In some applications, it is desirable for a product to pass through the light curtain without stopping the hazardous movement. This configuration can be achieved through the use of muting.

General Features

This safety function application technique explains how to connect and configure an L-type muting system with two sensors, for one-way passage, including an override (manual override) function and an additional emergency stop (E-stop) button. The system is based on the Guardmaster® 440C-CR30 configurable safety relay.

Advantages

  • Compliance with the main applicable safety standards
  • Use of certified safety solutions
  • Solution that allows for future expansions
  • Possibility of integration with control systems via the EtherNet/IP network

 

Limitations and disadvantages

  • The CCW software must be updated to the latest version
  • This solution is part of the machine compliance process; the complete compliance process must be carried out 

 

Is this useful to me?
