 Explanation
(1) The GL-RHG is not muted when the mold is at or stays at the bottom dead
center of the press cycle. At this point, the GL-RHG continues normal
operation and the OSSD goes OFF if the GL-RHG gets interrupted.
(2) When switch A1 turns ON first, and then switch A2 turns ON, the GL-RHG
goes into the muted condition and the OSSD does not turn OFF, even if the
GL-RHG detects an interruption.
(3) The GL-RHG continues the muted condition because both switches stay
turned ON and the mold continues to stay at the top dead center position.
(4) The GL-RHG will go back to normal operation (not muted) as soon as sen-
sor A1 turns OFF after the mold starts downward.
(5) The GL-RHG continues normal operation while the mold is going down-
ward.
