Arrangement of the muting sensors
6.2.1 Basic information
Before you begin with the selection and mounting of the muting sensors, please note the following:
• Muting must be triggered by two independently wired muting signals and must not be fully dependent
on software signals, e.g. from a PLC.
• When using a transceiver as a safety sensor and Reflection Light Beam Devices as muting sensors,
electrical connections are only necessary on one end, e.g. of a conveyor line.
• Always mount muting sensors so that the minimum distance to the protective device is maintained
see chapter 6.2.3 „Minimum distance for optoelectronic muting sensors“.
• Always mount the muting sensors so that the material is detected and not the transport device, e.g.
the pallet.
• Material must be allowed to pass through unimpeded; people must be reliably detected.

Muting sensors detect material and supply the signals necessary for muting. Standard
IEC TS 62046 provides basic information on arranging the muting sensors. This information
must be observed when mounting the muting sensors.
WARNING
Unintentionally triggered muting may result in serious injury!
Mount the muting sensors in such a way that muting cannot be unintentionally triggered by a person,
e.g. by simultaneously activating the muting sensors with a foot.
Mount the muting indicator so that it is always visible from all sides.
