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.
