Protected Field - Pilz PSENvip RL D P Set Operating Manual

Function description
The shape and size of the protected field depend on the bending function 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 entitled "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 stopping of the press stroke.
