Notes on Safety

About this chapter
The product has been manufactured according to the accepted rules of current technology. Even
so, there is risk of injury and damage to equipment if the following chapter and safety
instructions of this documentation are not followed.
O
Read these instructions completely before working with the product.
O
Keep this documentation in a location where it is accessible to all users at all times.
O
Always include the documentation when you pass the product on to third parties.
Intended use
The dual valve is a safety component in accordance with Machinery Directive
2006/42/EC and is therefore provided with the CE mark. The intended use
is the exhaust in compressed air systems or equivalent applications and
the prevention of unexpected start-ups.
O
See section 16 "Technical Data" for the standards and test values complied with and adhered
to by the product.
O
The pressure regulator may only be used within the limits listed in the technical data.
The product is intended for professional use only.
Intended use includes having read and understood this documentation, especially the chapter 2
"Notes on Safety".
Safety function according to ISO 13849
The dual valve is a redundant system according to the requirements of ISO 13849-1 and -2, in
which the pneumatic safety functions "safe exhaust" and "prevention of unexpected start-ups"
are ensured, including in case of a valve fault (e.g. due to wear).
With correct integration in the control system in accordance with ISO 13849-1 and -2, these
products can be used in up to category 3 and 4 and a performance level up to e can be achieved.
The valves used have a slider position detection and improve the diagnostic coverage level of the
control.
The product has been engineered and manufactured according to the fundamental and proven
safety principles of ISO 13849-2.
Common Cause Failure – CCF
The following measures must be ensured by the user to prevent failures due to common causes:
W
Observe the temperature range (see chapter 16 "Technical Data")
W
Observe the compressed air quality (see chapter 10 "Operation")
W
Observe the permissible operating pressure (see chapter 16 "Technical Data")
W
Observe the permissible voltage and current range for coils and sensor (see chapter 16
"Technical Data")
Proper use of this product also includes the user knowing and implementing all further
requirements from ISO 13849-1 and -2 (e.g. measures for the software, diagnosis, against
further CCF, against systematic failures etc.) and then evaluating whether the necessary
performance level has been achieved.
Improper use
WARNING:
Misuse may result in injury or damage.
The following applications are therefore prohibited:
W
Use in non-industrial applications/residential areas,
W
Outdoor use,
W
Use outside of the product limits defined in the technical data,
W
Unauthorized modifications,
W
Use in reversible operation (reversing of supply and exhaust air),
W
Vacuum operation,
W
Use in ATEX certified areas,
W
Use near to ferromagnetic parts (a safety clearance of 30 mm to the sensor must be
maintained and magnetic fields must generally be avoided)
Any use other than that described under Intended use is improper and is not permitted.
AVENTICS GmbH is not liable for any damages resulting from improper use. The user alone
bears the risks of improper use of the product.
