1-6-2. Calculation of Response Time of Cascaded Segments
The F3SG-RA can be used in cascade connection.
In case of a cascade connection, a response time is determined by the total number of beams.
If the total number of beams of all F3SG-RA in a cascade connection is 140 or less, its response time
is 12 ms (Code A)/13 ms (Code B). The number of beams of respective F3SG-RA, however, must be
112 or less. If an F3SG-RA with 113 or more beams is included in the cascade connection, its
response time is 17 ms (Code A)/18 ms (Code B).
The F3SG-RE cannot be used in cascade connection.
The diagram below summarizes the relation described above.
