Example: Sequential Muting with 4 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.
Application Setup
Sensor 11 is connected to Muting Signal 11. Sensor 12 is connected to
Muting Signal 12. Sensor 21 is connected to Muting Signal 21. Sensor
22 is connected to Muting Signal 22.
