2 Safety
2.1 General safety information
Note
Failure of the safety function
Common cause failures, subsequently called CCF, cause the failure of the safety func
tion, 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 for managing the CCFs are observed
(è3.2 Common cause failures (CCF) and 15.1 Safety characteristics).
Note
Failure of the safety function
Failure to observe the technical data can result in the failure of the safety function.
 Observe the technical data (è15 Technical data).

2.2 Intended usage
The MS6-SV-...-D-10V24 hereafter called the MS6-SV-D, is an electro-pneumatic soft-start/quick
exhaust valve designed in accordance with EN ISO 4414. The MS6-SV-D is intended for the following
purposes:
– Pressure release and pressure switch-on in higher levels in accordance with EN ISO 13849-1
– Gradual pressure build-up in pneumatic piping systems and terminals in industry
The MS6-SV-D has two safety functions:
– pressure release
– protection from unexpected start-up (non-switching)
The MS6-SV-D is designed to change from the normal position to the switching position when both
coils are energised simultaneously. The normal position is achieved by switching off both coils.
The MS6-SV-D is intended for installation in machines or automation technology systems and must be
used exclusively as follows:
– in an industrial environment
– within the limits defined by the technical data (è15 Technical data)
– in its original condition, without unauthorised modifications
– in perfect technical condition
– in accordance with the specifications of these operating instructions
2.3 Foreseeable misuse
The following foreseeable misuses are among those not approved as intended use:
– use outdoors
– use as control for coupling/braking combinations on mechanical presses
– bypassing of the safety function
– use in reversible operation (using supply air instead of exhaust air, and vice versa)
– vacuum operation
Note
In the event of damage caused by unauthorised manipulation or use other than that
intended, the guarantee is invalidated and the manufacturer is not liable for damages.
