Frequently Asked Questions

Safety Sensor Topic: Muting Function

 

FAQ No. FAQ02275

 

Question

 

What is the muting function?
 

 

Answer


Muting Function

 

The muting function temporarily disables the safety function when a workpiece or conveying palette passes through the detection area of a Safety Light Curtain or Safety Sensor.

 

The OMRON F3SN-series Safety Light Curtains and the F3SH-series Multibeam Safety Sensors do not have a muting function, but the muting function can be used if the F3SP-U2P Muting Controller for Safety Sensors (sold separately) is used in conjunction with these products. Refer to the following application example.

 

Example Application Using the Muting Function by Combining an F3SN with an F3SP-U2P

 

Problem: The AGV breaks the Safety Light Curtain to send the workpiece towards the robot, so the work process stops. Solutions: Two Muting Sensors are installed in front of the Safety Light Curtain so that workpieces and people can be distinguished by the operation timing.

 

How Muting Function Works

 

Note: The F3SP-U2P Muting Controller distinguishes between workpieces and people passing through by the timing of the detection by Muting Sensors A and B.
Adjust where Muting Sensors A and B are installed and the sensing direction so that the passage of a person does not interrupt the beams from both Sensors.
