2. Muting sensors must be arranged such that muting
cannot be triggered unintentionally by any person
(Fig. 1 and 2).

3. Muting must only be activated within the time span
when the conveyor with its load is blocking access to
the hazardous area.
4. Muting must be activated automatically, but must not be
dependent on one single electrical signal.
5. Muting must not be entirely dependent on software
signals.
6. The muting condition must be cancelled, and the safety
device re-primed, as soon as the pallet has passed
through.
