Festo — MS6(N)-SV-...-E-10V24 — 2021-11e
Identification of signal transitions
If safety outputs with test pulses are used to control the product, the following runtime performance
must be observed:
–
MS6-SV-E exhaust status
–
Test pulses < 3 ms are ignored
– MS6-SV-E pressurise status
–
Test pulses < 12 ms are ignored
Detection of shorts across contacts of the enable signals
In general, detection of shorts across contacts is required to guarantee performance level e.
Depending on the selected plug, either the product itself or the safety relay unit/PLC detects the
cross circuit.
