Five trends in safety engineering

The design and function of safety engineering is constantly evolving.
Find out how Treotham is keeping up with the trends with their Euchner safety

1. Digitisation increases machine

In complex networked installations and machines, providing functional
safety information about the door position and guard locking is often no longer
sufficient. Comprehensive diagnostics data supplied via IO-Link and bus systems
help with troubleshooting and give an insight into the status of the systems.
Simple configuration measures, for example in the ProfiNet network, reduce the
amount of wiring work. The safe signals are also sent via the bus. The Euchner MGB
series from Treotham makes it easy to integrate the very latest safety
engineering functions into existing networks.

2. Keeping everything under
control: managing access rights

It’s not only people that need to be protected from the harm that
machines can cause. It is also essential that the costly manufacturing process
is not interrupted by unauthorised or accidental interventions. In this case
key-operated rotary switches and passwords no longer provide adequate safety.
The solution is an Electronic-Key-System EKS that manages the access rights
centrally. However, the Euchner EKS from Treotham can do much more than that.
For example, a time limit can be set for Electronic-Keys and they can be
blocked if they are lost. Other options include different access levels for
different machines, managing user groups, and much more. It’s all possible with
the EKS.

3. Electronic prevention of

When safety systems are bypassed, there is generally a good reason for
doing so. Often certain tasks can be carried out only when a safety door is
open, but this can be dangerous. Electronically coded actuators that are ‘married’
to the accompanying safety switch allow almost all types of tampering to be
prevented. However, if the safety door has to be open for the work to go ahead,
the risk can be reduced by limiting the axis movements and pressing an enabling
switch, for example. To activate this safety function, Euchner has developed a
procedure for safely selecting operating modes based on the EKS-FSA. Only
employees with the appropriate training are given the personalised
Electronic-Key to allow them to carry out tasks involving an increased risk.

4. Whatever you want: personalising
safety products

All safety applications are different. For example, the emergency stop
often has to be integrated into the door locking mechanism and the request and
acknowledgment buttons may need to be fitted directly to the safety door. Treotham’s
special extended variants for safety switches with guard locking meet many of
these requirements. The new MGB2 Modular even allows users to make the
functional modifications themselves. By plugging in function submodules, users
can adapt the Multifunctional Gate Box for specific applications. With more
than 20 different submodules on offer, there are plenty of options available.
In addition, new modules can be produced in small numbers to meet individual
customers’ requirements. The wide range of variants and the options for
personalisation make the systems more user friendly, which in turn increases

5. The smaller the better:
increasingly compact safety switches

In the past the appearance of production machines was relatively
unimportant when compared with their functions. However, in recent years
developers have increasingly focused on the design of the machines, which is
often regarded as a reflection of their high standard of quality. For safety
engineering products this may well mean that they need to be concealed in the
machine cover, but it is essential that they continue to function without
problems. Fortunately the high level of electronic integration that is now
possible has enabled printed circuit boards to be reduced in size. Innovative
technologies allow products to be made smaller and smaller. The smallest
Euchner RFID configurator from Treotham is the same size as a 6mm plastic dowel
and is almost invisible once it has been installed in a door.
