5.15.3 Muting in one direction
DANGER!
Loss of the safety function when L muting is applied incorrectly.
– Use L muting only to remove material from the danger zone.
} The muting status occurs
– When the signal at the muting input 2 switches to High after the muting input 1 has
also switched to high (or the muting input 1 switches to High after the muting input 2)
and
– The delay between the two signal changes is in the configurable area Muting activa-
tion delay [ms]. The max. delay can be configured between 1 and 16 seconds.
} The muting state is ended
– When the configured time is reached or
– after a multiple of the delay between the activation of the two muting sensors.
The Factor activation delay can be selected between 2 and 16.
