the muting function might become valid with the timing that the machine designer
cannot expect and could result in death or serious injury.
<Installation condition example of muting sensors>
1) Shorten the distances between muting sensors A to C and between B to D than the whole length of the sensing object.
2) The time of the sensing object to be passed through the muting sensors A to B shall be 0.03 to under 3 sec.
Distance between A and B (m) < S (m/sec.) × 3 (sec.)
