To enable the muting function, D3 and d2 must satisfy formulas (3) and (4), respectively.
This distance must prevent the muting function from being enabled by a person passing through the
muting sensors. Also, install the F3SJ-B and muting sensors so that each workpiece passes through
all muting sensors before the next workpiece arrives at the first muting sensor.
