The shape and size of the protected field depend on the bending func-
tion and the machine-dependent overrun. A reduced protected field is
possible for box bending and/or back gauge mode (for the size of the
protected field please see "Protected field" section and the chapter en-
titled "Technical Details").
If an object encroaches into the detection zone, both output signal
switching devices (OSSD1 and OSSD2) on the PSENvip will switch to
the OFF-state. The safety system will use these signals to initiate stop-
ping of the press stroke.
