0V or +V Open
WARNING
Use only a muting sensor that is capable of the above <Output operation of muting sensors> .
If a muting sensor other than the above is used, the muting function may activate at a time not in-
tended by the machine designer and create a risk of death or serious injury.
<Start conditions for muting>
The muting state activates when the following conditions are all satisfied.
● The device is not in the lockout state.
● The device is in the light receiving state and the control output (OSSD 1 / 2) is ON.
● The time difference when muting inputs A and B change to ON is from 0.03 to under 3 sec.
<Release conditions for muting>
The muting state deactivates when any one of the following conditions is satisfied.
● The device enters the lockout state.
● Muting input A or B turned OFF for at least 20ms.
● The muting time exceeded two hours.

(1) The distance between muting sensors A and
C, and B and D, must be shorter than the total
length of the sensing object.
(2) The time required for the sensing object to pass
from muting sensor A to muting sensor B must be
0.03 sec to under 3 sec.
Distance between muting sensors A and B (m) <
S (m/sec.) x 3 (sec.)
