INFORMATION
Please note that the central segments are 1 mm behind the bending line.
With box bending you must ensure that the side panels of the box do not
encroach into this area.
The two following sections explain the basic mode of action of the protected field during a
press stroke (interrupted and uninterrupted).
INFORMATION
The cycle of a press stroke with the corresponding inputs and outputs is ex-
plained in this chapter, in the section entitled "System cycle".
4.2.1
Dynamic muting
An advance measuring field is located below the protected field. If is interrupted, the dy-
namic muting is started. Dynamic muting ensures that the danger zone between upper tool
and workpiece is monitored up to a remaining gap of 6 mm during the downward movement
of the press.
The distance of the advance measuring field to the lower edge of the protected field is con-
stant. The distance to the top edge of the protected field varies according to the length of
the overrun.
