The PSENvip is a camera-based protection system with integrated over-
run monitoring for press brakes. It consists of a transmitter and receiver,
which are fixed to the moving part of the press brake, the upper die. The
detection zone between the transmitter and receiver monitors the imme-
diate danger zone below the moving upper tool.
The detection zone moves with the upper die, providing mobile safe-
guarding of the danger zone. If an object encroaches into the detection
zone, both output signal switching devices (OSSD1, OSSD2) on the
PSENvip will switch to the OFF-state. The programmable safety system
will use these signals to initiate stopping of the press stroke.

Funktion_Optik
The receiver evaluates the parallel beams generated by the transmitter.
The beam is enclosed by the illuminated target area. The lens on the re-
ceiver only detects light that runs parallel to the optical axis. This guar-
antees stability against diffused light.
