Muting Sequence
1. In the block diagram above, the light is not interrupted between MS11,
MS12, MS21, and MS22 and the light curtain, so the Output Enable signal
is ON.
2.
For the entrance, as the workpiece moves to the right and MS11 and MS12
go ON in order (MS22 and MS21 go ON in order at the exit), muting is en-
abled, and the Muting Status goes ON.
3.
As the workpiece continues advancing, the Output Enable signal is kept
ON even if the light curtain is obstructed.
4.
As the workpiece continues advancing, the workpiece is no longer detect-
ed by MS21 at the entrance (MS12 at the exit), the muting status is
cleared, and the Muting Status goes OFF.
