Access guarding with muting function

Quickly and easily integrated

​Muting functions control and monitor the bridging function for material transport on conveyor lines. They use the signals from muting sensors to distinguish between transported goods and persons. Depending on the application, muting functions are available in various safety sensors and control components.​

Operating principle of muting

In addition to the safety sensor, additional 'muting sensors' are used to distinguish between transported goods and persons in the case of access guarding with muting function.​
The muting sensor signals are evaluated either in the safety sensor or in an external control unit.​

Advantages for you

  • Access guarding with muting function can be integrated into the safety circuit of the system control easily using OSSD outputs​
  • The muting functions are integrated in the devices and can be easily configured if required. Safety functions do not need to be programmed.​
  • 2 and 4-sensor muting as well as muting functions in safety sensors and in control devices provide solutions for all muting applications​

Typical areas of application for muting solutions

2‑sensor muting, timing controlled

The universal solution for entry and exit. The muting sensors are arranged in a cross formation.

2‑sensor muting, sequence controlled

Only for exit zones. For increased requirements, e.g., related to the shape and position of the load. The muting sensors are aligned parallel to each other.​

4‑sensor muting, timing controlled

For entry and exit. For increased requirements, e.g., related to the shape and position of the load. The muting sensors are aligned parallel to each other.

Fast and simple commissioning using muting sensor sets

With their pre-mounted and ready‑to‑use setup, the Set-AC muting sensor sets ensure fast and error‑free commissioning. The sets are used together with the MLD multiple light beam safety devices and the MLC safety light curtains. They are mounted easily to the side of the DC/UDC device columns or directly to the MLD and MLC devices. The AC-SCM sensor modules also ensure simple connection of all components. Muting sensors, restart pushbutton and display element are connected to the modules, and a collector cable is used to connect them to the MLD or MLC devices.

Fully preconfigured

The MLDSET protective sensor sets offer complete solutions for access guarding with muting function. Thanks to the ready‑to‑use design with pluggable connections, the pre-mounted sets guarantee efficient setup and fast commissioning. A wide selection of turnkey variants optimized to the different muting tasks is available.
