Be sure to use a muting sensor that satisfies the
<Output operation of muting
sensors>
above. If the other muting sensor not satisfying the specification above,
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.)
S: The moving speed (m/sec.) of the sensing object
3) The time of the sensing object to be passed through the muting sensors C to D shall be under 3 sec.
Distance between C and D (m) < S (m/sec.) × 3 (sec.)
S: The moving speed (m/sec.) of the sensing object.
