Example for 1
SF_MutingSeq
in forward direc-
tion with four
sensors
If muting sensor MutingSwitch12 (MS_12) is activated by the product after MutingSwitch11
(MS_11), the muting mode is activated.
2
Muting mode remains active as long as MutingSwitch11 (MS_11) and MutingSwitch12 (MS_12)
are activated by the product. The product may pass through the light curtain without causing a
machine stop.
3
Before muting sensors MutingSwitch11 (MS_11) and MutingSwitch12 (MS_12) are disabled,
muting sensors MutingSwitch21 (MS_21) and MutingSwitch22 (MS_22) must be activated. This
ensures that muting mode remains active.
4
Muting mode is terminated if only muting sensor MutingSwitch22 (MS_22) is activated by the
product.
