Description
1
Muting mode is enabled when the passage of
a workpiece turns ON
MutingSwitch11
(MS_11) and then
MutingSwitch12
(MS_12).
2
Muting mode is enabled as long as
MutingSwitch11
(MS_11) and
MutingSwitch12
(MS_12) remain ON due to
the workpiece. This allows the workpiece to
pass through the light curtain without stop-
ping the machine.
3
MutingSwitch21
(MS_21) and
MutingSwitch22
(MS_22) must turn ON
before
MutingSwitch11
(MS_11) and
MutingSwitch12
(MS_12) turn OFF. This
ensures that muting mode remains ON.
4
Muting mode is ended if only
MutingSwitch22
(MS_22) is ON due to the workpiece.
