Common cause failures (CCF)
Common cause failures cause the loss of the safety function, since in this case both channels in a two-
channel system fail simultaneously.
Through the following measures, you 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 conforming to the technical data, in particular avoidance of
flash rust particles (for example, 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 through use of a pressure-relief
valve
Observe the technical data in chapter 14.
Note
Loss of the safety function
Non-compliance with the technical data can lead to loss of the safety function.
