The two following sections explain the basic mode of action of the pro-
tected field during a press stroke (interrupted and uninterrupted).
4.2.1 Dynamic muting
Dynamic muting 4- Funktion_vorauseilendes_Messfeld_Muting_Allgemein
An advance measuring field is located below the protected field. If is in-
terrupted, the dynamic muting is started. The dynamic muting ensures
that the danger zone between upper tool and plate is monitored up to a
remaining gap of 6 mm during the downward movement.
Funktion_vorauseilendes_Messfeld_Groesse
The distance of the advance measuring field to the lower edge of the
protected field is constant. The distance to the top edge of the protected
field varies according to the length of the overrun.

Procedure:
1. The press is on downward movement. The protected field moves
down with the upper tool.
2. The advance measuring field touches the workpiece. The outputs
Mute1 and Mute2 at the receiver are set = 0.
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.
INFORMATION
The cycle of a press stroke with the corresponding inputs and
outputs is explained in this chapter, in the section entitled "Sys-
tem cycle".
