Camera-based protection system PSENvip

The safe automation solution for press brakes

Camera-based protection system PSENvip

The camera-based protection systems PSENvip are mobile protection systems. They monitor the whole bending process visually. When installed on the upper die, they detect even the smallest foreign body in the protected field between the transmitter and receiver. This product is characterised by robustness and high machine availability.

The camera-based protection systems PSENvip include the following two product types:

Camera-based protection system PSENvip - the safe, complete solution for press retrofits

Combine the mobile protection system PSENvip with the configurable control system PNOZmulti or the automation system PSS 4000! Together with the FAST Control Unit in the automation system PSS 4000, the productive version of PSENvip can achieve a productivity increase of up to 50 per cent during dynamic muting mode. Thanks to the clear diagnostic messages on the integrated LCD display, there are no barriers to productive working!

Important for you the customer: If the parameters for the PSENvip (basic and productive version with PSS 4000) are set correctly, without any safety-related errors, then this is not a significant change in accordance with the Equipment and Product Safety Act – the work involved in certification is minimal.

Further information is available in the Lexicon entry "Significant change".


Camera-based protection system PSENvip 2 – the integrated solution for modern press brakes

PSENvip 2 is the second, extended generation of the camera-based protection system. Ease of handling, maximum productivity and high machine availability characterise this product. The volume of the receiver has also been reduced by around 50 per cent. PSENvip 2 can be used with PSS 4000. Connect the Fast Analysis Unit of the PSENvip 2 as a module! The result: fastest shutdown time and short overrun distance for the press brake tool.

PSENvip 2 does not need a device display: all of the commissioning and configuration work is carried out easily and directly via a web interface on the press brake controller. As a result, the user can make all the settings centrally in one place.

Protection system brings greater productivity when press braking – The benefits

  • Maximum safety in accordance with the safety standards EN 12622
  • Innovative optical system with LED light for high availability and productivity (compared to laser-based systems)
  • Robust protection systems – insensitive to reflections and external/diffused light, as well as vibration and temperature stratification (e.g. due to heated tools)
  • Long service life of the LED light source means reduced maintenance work
  • Easy initial adjustment and fast tool changes – thanks to innovative technology and software for reduced tooling times
  • Commissioning and configuration via an integrated display (PSENvip) or web interface on the press brake controller (PSENvip 2)
  • Very short shutdown time and short overrun distance of the press brake tool – thanks to integrated FAST functionality in the evaluation unit Fast Analysis Unit (PSENvip 2)

Features of the protection system

Features of the protection system
  • Large protected field (19 x 38 mm) with three sensing areas
  • Achievable distance between the transmitter and receiver of up to 10 m on PSENvip and up to 13 m on PSENvip 2
  • Advance measuring field for detecting the plate
  • Integrated camera chip uses proven SafetyEYE expertise
  • LED light beam is safe to the human eye
  • Complete integration into the environment thanks to the Fast Analysis Unit (in the PSS 4000) and configuration via the HMI of the press brake controller (PSENvip 2)

The complete solution for press brakes and press retrofits

Dynamic muting for greater productivity

The control system PSSuniversal PLC performs two central tasks: Monitoring of dynamic muting and speed profile during the braking process. The functions are available as blocks in the software platform PAS4000. As a result, it's possible to approach the plate for longer at high speed during the bending process. So the time that the upper tool travels at reduced speed is reduced to a minimum.

Safe press braking with large tools

Some tools used on press brakes cannot be safeguarded using a conventional solution on account of their size. In accordance with the standard EN 12622, however, each bending line must be protected by a protected field 15 mm in advance, on the operator side. A requirement for complying with this normative specification is that the tool is situated completely within the protection system's field of vision. The protection systems PSENvip can help in this case.

The special tools function has been certified by TÜV Nord and provides a classification of the various tool sizes for the protection systems PSENvip. In tool class 1, protection is in accordance with the standard. However the camera image for tool classes 2 and 3 can only partially identify the tool in view of its size.

The camera-based protection systems PSENvip can also safely monitor large tool shapes: by means of raising the switchover point or changing the speed when lowering down onto the sheet metal. They check the tool contour and assign it to tool class 1, 2 or 3. The established class is communicated to the controller, which then issues enables for class 2 and 3 tools. The switchover points defined by the risk analysis are also monitored.
