5.2.4.7.7 Partial Muting
The “Partial Muting” function can be used to secure the danger zone even more effectively. With this ap-
proach, only part of the ESPE (e.g. at object height) is hidden within a valid muting sequence, while the other
light beams remain permanently active and cause the OSSDs to be switched off if interrupted.
Area 1
The area is exempted from the muting.
Here, the beams of the ESPE are permanently active
independently from the muting sequence
.
Area 2
Area is muting-relevant.
Here, the beams of the
ESPE are bridged depending on the muting sequence
.

NOTE!
• Area 2 (muting area) can be taught-in by transporting the object into the safety field and
teaching in the number of hidden beams.
• Area 2 consists of cumulated beams. For the muting, the area between the first and the
last defined beam is activated.
• If area 1 is penetrated during an active muting sequence, the muting is ended.
• With the additional function “Full Muting Enable” (
muting
can be extended to the entire safety field. This means that a single object with a greater
height can be transported through the safety field.
