5.2.4 Muting

Muting is a function that safely bridges the ESPE for a short time so that objects can be moved through the
safety field without the OSSDs switching off.
The muting cycle is activated as soon as the responsible sensors detect an object. When arranging them, it is
therefore important to ensure that the muting cycle can not be triggered by a person.
We differentiate between linear muting and cross muting. With a linear arrangement, several sensors are
arranged one behind the other. With cross muting, two sensors are arranged so that their beams cross.

Additional signals, for example from muting sensors or a PLC, are required to activate the muting function.
This means that the ESPE can check that the muting takes place correctly and guarantee that a person enter-
ing the danger zone is still reliably detected.

The basic requirements for starting a valid muting sequence are:

• OSSDs in ON state (safety field of the ESPE free)

• Muting sensors in OFF state (no object detected)

General muting process

1 Muting object is transported in the direction of the

danger zone.

Safety field: free
MS: free (signal 0)
OSSDs: on
Muting: inactive

2 Muting object actuates

muting sensors

Safety field: free
MS: actuated (signal 1)
OSSDs: on
Muting: active
