St type normal function timing diagram:
The front protective area laser (L1) of the normal mode sensor is shielded, and the middle
protective area laser (L2, L3) plays a protective role.

The muting mode may be selected when the bender processes complex shape workpiece.
Other protection measures should be taken to protect the operator under this mode.
