(1) The workpiece is approaching the
protective zone but the GL-RHG
does not go into the muted condi-
tion because all of the sensors are
OFF. At this point, the GL-RHG
continues normal operation and the
OSSD goes OFF if the GL-RHG
gets interrupted.
(2) The workpiece interrupts the
beam of sensor A1, and turns ON
the output. However, the GL-RHG
still continues normal operation.
