Camera-based protection system PSENvip

The camera-based protection systems PSENvip are mobile protective devices. 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
• Camera-based protection system PSENvip 2 – the integrated solution for modern press brakes

You’ll find the required cable, connector and adapter accessories under Connection technology

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

Combine the mobile protective device 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: Correct and fault-free (from a safety-related standpoint) parameter setting of the PSENvip (basic and productive version with PSS 4000) represents no significant change in terms of equipment and product safety legislation – certification work is minimised.

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. Easy handling, maximum productivity and high machine availability are the hallmarks of PSENvip 2. The volume of the receiver has also been reduced by around 50 per cent.

Now use PSENvip 2 in combination with the automation system PSS 4000 too! All you need to do is connect the Fast Analysis Unit of the PSENvip 2 as a module. Benefit from an even shorter shutdown time and a short overrun distance on 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, you as the user can make all the settings centrally in one place.

• 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)

• Large protected field (19 x 38 mm) with three sensing areas
• Achievable distance between the transmitter and receiver of up to 10m on PSENvip and up to 18 m on PSENvip 2
• Advance measuring field for detecting the plate
• 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 camera-based protection system PSENvip 2 and the automation system PSS 4000 are synonymous with maximum productivity and easy handling. With the bending angle measurement module, usable image data is forwarded from the camera-based protection system directly to the press controller, thereby guaranteeing an efficient bending process. The bending angle value is displayed on the machine’s user interface. Both the time-consuming manual angle measurement process and expensive displacement measuring systems are no longer necessary. In this process, you benefit from: 

• Time savings
• Cost savings
• Less space required for fitting additional devices

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 due to their size. In accordance with the standard EN 12622, however, each bending line must be safeguarded by a protected field min. 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.

With the special tools function certified by TÜV Nord, various tool sizes are now classified 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.

The long-range version PSENvip R LR is the first and only protective device for press brakes with a protection range of up to 18 metres. This makes it ideal for monitoring special presses such as tandem presses. The installation of PSENvip R LR on existing presses is quick and easy: The transmitter remains the same, you only have to swap the receiver. Monitor your tandem press with just one protection system; there’s no need to combine a mobile protective device and light curtains!

In the long-range version, you also get a hot plug-capable protection system: If you place two press brakes next to one another, you can simply remove the transmitter and receiver in the centre. The transmitter from machine 1 then works with the receiver from machine 2 – without having to restart! You thus avoid unnecessary downtimes with PSENvip R LR. Furthermore, the long-range version of PSENvip impresses with its customary high robustness.
