Figure 65 - Sequence Error
Example: Sequential Muting with Four Sensors (forward direction)
In this example, four through-beam photoelectric sensors are set up as the muting
sensors with intersecting detection zones. Use this configuration when the length
of the workpiece being transported is a fixed length long enough to activate
sequentially-mounted muting sensors.
