4-1-4. Mutual Interference Prevention
Do not use the sensor system with mirrors in a retro-reflective configuration. Doing so
may hinder detection. It is possible to use mirrors to alter the detection zone to a 90-
degree angle.
When using more than 1 set of F3SG-R in adjacent areas, the emitter of one F3SG-R
may interfere with the receiver of the other, causing the safety functions to stop working
properly. Install and configure them so that mutual interference does not occur.
When two or more F3SG-R systems are mounted in close proximity to each other, precautions should
be taken to avoid one system interfering with another, such as by back-to-back configuration, physical
barrier, Scan Code Selection and adjustment of distance between adjacent sensors.
Example
The scan code feature of the F3SG-R system allows for placement of systems in close proximity and in
line with each other. The distinctive coding of the beams provide for unique operation of a system while
in view of another system with a different scan code. Two unique codes are available on the F3SG-R.
The emitter and receiver units must be set to the same scan code for the receiver to enter the Machine
Run state. The scan code is selectable by the Rotary Switch on the emitter and receiver units.
Refer to
for more information on the scan code feature.
Refer to
for more information on setting the scan code by the Rotary Switch.
