DIN ISO certified – BVS Industrie-Elektronik

Our quality promise to you

 

In addition to adhering to quality directives and environmental standards, we allow ourselves to be measured against the quality standards of the manufacturers. Due to the health and safety requirements of the Machinery Directive 2006/42/EC, we use original components approved by the manufacturer or legislator for our repairs. Components discontinued by the manufacturer or that are no longer available are analysed as part of the reverse engineering process and replaced by currently available and approved technology.

In addition, our internal testing lab always works in strict adherence with ISO TS16949 / VDA 6.4
In accordance with our high standards, we, for example, ensure receipt of the type examination certificate, the CE standard, the UL quality mark and many more, enabling us to guarantee the validity of your operating licence after every repair.

DMSZ - BVS Industrie-Elektronik GmbH

Proven quality instead of improvised risk

As a repair service provider, we repeatedly discover improper repairs, which are often caused by the use of reproductions of safety-relevant components, such as power packs, transformers and relays. This often results in blatant safety risks that cannot even be counteracted with a repair.

Exclusive use of new components authorised by the manufacturer or legislator during repairs and the use of more than 100 original test stands for all manufacturers ensure that BVS can guarantee the complete fault-free function of the module. By completing simulations under actual conditions and tests with a full load applied, it is also ensured that modules will withstand rigorous daily operation. Play it safe and appoint us as your reliable partner, to minimise the risk of another malfunction relating to the operating licence, health and safety and service life of the machine.

Examples of incorrect repairs Risks you do not take with a quality provider

You can't? No way!

The maintenance of this hand-held operating device was literally an "extraordinary" achievement. The proper functioning of the inner safety-relevant switching element is endangered by the broken housing!

Adhesion

Components are often glued in place instead of soldered. This approach is faster and cheaper. However, components attached in this way are not safe. A perfect connection cannot be guaranteed.

Art instead of quality

Every now and then, very simple solutions are found for very complex tasks. As nice as these solutions are, they are not permissible and pose a hazard to humans and the machine.

Perforation

The housing, key foils and switching matrix have been perforated when fastening the screws. The intended function of individual keys can therefore no longer be guaranteed. The protection class is also no longer guaranteed.

Faulty insulation

Cables have been installed incorrectly, generating pressure points so that the cable isolation has subsequently worn through. The danger to humans and the machine increases and a failure is likely.

Loose connection

As the component has not been soldered correctly this will result in a loose connection. The component can then not be implemented reliably, the risk of consequential damage to other components increases uncontrollably and the safety of the machine operators is not guaranteed.

Uncleaned soldering points

Soldering points that have not been cleaned will damage the surface of the circuit board. Predictable production can thus no longer be guaranteed and the probability of consequential damage to other components and danger for machine operators increases.

Manual wiring

The following provides an example of a manually wired, non-original replacement part. If connections are not secured, contact will be lost. The machine is likely to fail.

Negligent bridging

Grossly negligent approach by bridging the faulty basic material.

Safety-relevant components

The original versions of the components listed below are not available to or are very difficult for unauthorised repair companies to purchase. This is why solutions for these components are often improvised, reconstructed or a supposed alternative is installed which can ultimately pose significant safety risks during operation of the module.

You should monitor these components following repairs on your modules. These are relevant to safety!

Power packs

BVS Electronics retrofits the latest version of power packs as standard.

The design of power packs and power supplies has changed dramatically in the last few years. The current layouts focus on safety and efficiency. They significantly reduce the loss of power and thus heat emissions into the surrounding area. Modern power supplies switch off reliably in the event of a fault. BVS Electronics therefore purchases these components from the manufacturer. This ensures that your repaired module always complies with the latest regulatory and manufacturer-specific requirements.


Transformers / transducers

BVS retrofits state-of-the-art transformers.

Transformers and transducers with an open design pose a significant safety risk. A cast and enclosed design is mandatory to protect against environmental factors, such as dust and dew. Humidity and dirt will change the transmission behaviour. Operational safety is not guaranteed for any other design as the CE mark and operating licence do not apply.


Relays approved by the manufacturer

BVS Electronics retrofits approved relays as standard.

These state-of-the-art relays have a considerably longer service life than previous versions due to their positively-driven double contacts. Retrofitting this type of relay is always necessary.


Older versions of approved relays

These relays are technically safe, however, they are not the latest version which will considerably reduce the service life of the module. BVS Electronics replaces old versions with the latest relay version as standard and, of course, only uses components approved by the manufacture or legislator.


Prohibited relays

Frequently installed but not approved by the manufacturer.

Especially in SIEMENS SIMODRIVE 611D and MLFB 6SN1118-XXXXX-XXXX control units, the SR4 D/M safety relay manufactured by Tyco with positively-driven contacts in accordance with EN 50205 is often replaced with a relay without positively-driven contacts by unreliable repair companies.

The installation of unapproved components will results in the termination of the operating licence and possible the CE approval. In the event of damage, especially personal injuries, the appointed assessors will evaluate the state of the system.


IGBT drivers

These IGBT drivers are also installed without approval. These installations jeopardise the safety of the machine operator. These safety risks and the fact that the modules no longer comply with the relevant conformity declarations and approvals of SIEMENS AG contravene the EC Machinery Directive 2006/42/EC. This not only applies to the control units but the operating licence for the entire machine.


Plug-in connections

BVS retrofits connectors with additional lock for suitable modules.

Reliable plug-in connections with high-quality contact material, in particular designs that protect against inadvertent release, are essential for ensuring the function of modules. This additional lock guarantees a reliable connection even in the event of higher mechanical loads.

High quality repair is characterised by:

Cleaned circuit board – BVS Industrie-Elektronik

A professionally cleaned circuit board

Clean soldered connections

Exclusive use of new components authorised by the manufacturer and legislator

Clean, custom-fit screw connection of the housing

Preventive measures that increase the service life of the module

Comprehensive function and load test for the repaired module

Zero improvised or provisional measures applied to the module and its peripherals

Use of qualified specialist personnel who benefit from continuous further and additional training

Traceability and full documentation of all repair measures

Specialist ESD, warehouse and shipping packaging, such as the special nitrogen vacuum packaging provided by BVS that protects against corrosion and damage caused by environmental factors during storage.
