System Operation and Functions
Response time of “OFF (Synchronized)
ON” and “OFF (Not synchronized)
ON”
Response time of “OFF (Synchronized) ON” is the response time from when the F3SG-SR is in the
OFF state and the emitter and receiver are synchronized to when the F3SG-SR is turned to the ON
state.
Response time of “OFF (Not synchronized) ON” is the response time from when the F3SG-SR is in
the OFF state and the emitter and receiver are not synchronized to when the F3SG-SR is turned to the
ON state. This response time is longer than that of “OFF (Synchronized) ON” since the F3SG-SR
evaluates if it is blocked or unblocked, after the synchronization is established.
Scan Code Selection
The F3SG-SR has two scan codes (Code A and Code B). These scan codes have different internal
processing time. The use of different scan codes allows for placement of systems in close proximity
and in line with each other and minimize mutual interference.
The response time for Code A is 1 ms shorter than that for Code B.
Refer to 1-6-1. List of Models and Response Times for more information on the response time at the time of optical
synchronization setting.
Refer to 5-1-4. Mutual Interference Prevention for how to mitigate mutual interference.
Factory Default Setting
The factory default setting is Code A.
Both the emitter and receiver units must be set to the same code.
