Valid muting sequence:

Comments
1. Muting start
MS1 and MS2 are activated.
Both sensors must be activated within a
time frame of 4 seconds.
2. Muting active
MS1 and MS2, penetration of the
safety field.
The safety field is interrupted, the OSSDs
remain in the ON state.
3. Muting end
MS1 or MS2 are inactive or the maxi-
mum muting duration is reached.

NOTE!
• The safety can be increased further by positioning the MS at different heights, as their
fields of view do not cross at points in this case.
• If the function “Muting end through clearing of the ESPE” is activated, the muting se-
quence ends as soon as the safety field is free again.
• The “Gap suppression” function can increase the availability of the system by accepting
signal interruptions < 250 ms on the muting sensors.
