Robot automation and safety

ERobotisation involves many different factors, all of which are crucial to a well-functioning installation and a
satisfied customer. One of those factors is safety. At Cellro, several teams work together to bring this to the right
level so that each installation complies with Machinery Directive 2006/42/EG

How does Cellro Automation handle functional safety?

At Cellro, we focus on the functional safety of automation at four levels:

  • Electrical component level (safety PLC, relay, etc.);
  • Electrical design of safety circuits;
  • Software design of the safety circuits;
  • Safety integration with the customer’s processing machine.

These aspects are not visible to the customer, but they are essential for the robust and safe implementation of robot automation. To accomplish this, Cellro applies the EN-ISO standards under the Machinery Directive to design automation in accordance with legal requirements.

Visible safety for the customer

Functional safety is not visible to a customer, but what exactly is? Cellro uses three safety features that are immediately visible to the customer – and are effective:

  1. Physical protection by means of doors with locks. In this way the robot is partly or fully delineated by fencing. Access is only possible by unlocking the doors, and the customer must make a request to access the robot.

  1. Optical barrier by means of a safety laser scanner. In this way the robot is ‘invisibly’ shielded and the user has free access to the system. The safety laser scanner is set up in the emergency stop zone and the warning zone, so that the robot slows down when the barrier is broken.
  1. Physical and optical protection. In this way the robot is protected by means of fencing and light curtains. When the light curtain is interrupted, the robot switches off.
