
Explanation
(1) The workpiece is approaching to the detec-
tion zone, however, the SL-V does not go to
the muted condition because all of the sen-
sors are OFF. At this point, the SL-V continues
normal operations, and OSSD goes OFF if the
SL-V gets interrupted.
(2) The workpiece interrupts the beam of sensor
A1, and turns ON the output. However, the
SL-V still continues normal operation.
(3) The workpiece interrupts the beam of sensor
A1 first, and then interrupts the beam of A2.
Then, the SL-V goes into the muted condition.
and the OSSD does not turn off even if the
SL-V detects an interruption.
