2-3. Mutual Interference Prevention
Make sure the Responsible Person tests the operation of the F3SG-SR after setting with the End
Cap to verify that the F3SG-SR operates as intended. Make sure to stop the machine until the test
is complete. Unintended settings may cause a person to go undetected, resulting in serious injury.
When using more than one set of F3SG-SR's in adjacent areas, the emitter of one F3SG-SR
may interfere with the receiver of the other, causing the safety functions to stop working properly.
Install, configure and maintain them so that mutual interference does not occur.
The F3SG-SR has two types of mutual interference prevention methods, the Optical Synchronization and the
Wired Synchronization. When the Optical Synchronization method is used, the F3SG-SR prevents mutual
interference by the Scan Code Selection.
2-3-1. Mutual Interference Prevention of F3SG-SR
2-3-1-1. Optical Synchronization
Overview
Synchronization is required between an emitter and a receiver for normal operation of the F3SG-SR.
The optical synchronization method of F3SG-SR uses a specific beam to realize synchronization. The
beam is hereinafter called "synchronization beam".
By connecting the emitter and receiver with the Intelligent Tap simultaneously, the wired synchronization is configured. If
using the Intelligent Tap and optical synchronization configuration together, do not connect the emitter with the
Intelligent Tap.
Depending on sensor configuration, the synchronization beam is either of the followings:
• One segment system: End beams (Top or Bottom beam)
• Cascaded system : End beams (Top or Bottom beam) of the primary sensor
For an emitter and a receiver to synchronize, at least one synchronization beam must be unblocked.
The synchronization process is performed when:
(1) The power is turned on for an emitter and a receiver
(2) All beams of the primary sensor are blocked and then unblocked
(3) Synchronization is lost due to an error such as noise and ambient light
The sensor can maintain the synchronization in other cases than those described above and it is not necessary to keep
the synchronization beam unblocked all the time.
In the Optical Synchronization, use the same F3SG-SR models for the emitter and receiver.
