NOTICE!
Failure of the safety function
The product must be brought to initial position (exhausted status) at least once a month to guarantee
the safety function.
NOTICE!
Failure of the safety function
Common cause failures (CCF) cause the failure of the safety function, since in this case both channels
in a two-channel system fail simultaneously.
If measures to control the CCFs are not observed, the safety function of the soft-start/quick exhaust
valve can be impaired.
•
Make sure that the described measures observed and .
NOTICE!
Failure of the safety function
Non-compliance with the technical data can lead to loss of the safety function.
The electro-pneumatic soft-start/quick exhaust valve has control technology features which enable
performance level e to be reached for the safety functions. This product has been designed and manu-
factured in accordance with the fundamental and reliable safety principles of EN ISO 13849-2.
The following requirements apply to the manager:
–
Specifications on mounting and operating conditions in these operating instructions must be
observed.
–
For use in higher categories (2 to 4), the requirements of EN ISO 13849, e.g. CCF, must be con-
sidered.
–
The basic and proven safety principles of EN ISO 13849-2 relating to implementation and opera-
tion of the component must be satisfied.
–
When using this product in machines or systems subject to specific C standards, it must be in
compliance with the requirements specified in the standards.
–
Before using the product, a risk assessment in accordance with EN ISO 12100 as specified in the
EC Machinery Directive 2006/42/EG, appendix I, paragraph 1 and 1.1.2 is required.
–
The user is responsible for coordinating all applicable safety regulations and rules with the com-
petent authority and for compliance with regulations and rules.
Failures due to a common cause (Common Cause Failure – CCF)
The following measures ensure that common cause failures are avoided:
–
Compliance with the permissible values for vibration and shock stress
–
Compliance with the temperature range
–
Compliance with compressed air quality as specified in the technical data, in particular avoiding
flash rust particles (such as caused by servicing work) as well as compliance with the residual oil
content of max. 0.1 mg/m
3
when using ester-containing oils (which may, for example, be con-
tained in the compressor oil)
–
Compliance with the maximum operating pressure, if necessary with a pressure-relief valve
–
Clogging of the silencer must be avoided .
