5.2.4.7.5 Direction Setting (Only for 4-Sensor Muting)
This function increases the safety during muting by specifying and checking the sequence of the activation
and deactivation of the MS. If an object passes through the safety field in a direction other than the one de-
fined, the muting cycle is not initiated.

Direction A
MS1 or MS2 are activated before MS3 or MS4
Direction B
MS4 or MS3 are activated before MS2 or MS1
Deactivated
No direction specification
NOTE!
• This function is only relevant for muting types where it is possible to differentiate between
the direction of transport (see
• If the direction specification is deactivated, a cycle must be run through completely before
a muting cycle can be started in the opposite direction. If a change in direction takes place
while a muting cycle is in progress, this is likely to violate a time or sequence condition. If
the safety field is penetrated during this process, this can cause the OSSDs to switch off.
5.2.4.7.6 Muting End Through Clearing of the ESPE
The “Muting End Through Clearing of the ESPE” function enables the muting to be deactivated as soon as an
object has been transported out of the safety field of the ESPE. This shortens the muting time and improves
safety.

NOTE!
• Ending the muting after the ESPE are cleared takes place with a time delay of max. 500 ms.
• With 2-sensor linear muting, the “Muting End Through Clearing of the ESPE” function is
activated automatically. It can be parametrized with the other muting types.
