Overview
The detection zone between the transmitter and receiver monitors the immediate danger
zone below the moving upper tool of a press brake. The detection zone moves with the up-
per die, providing mobile safeguarding of the danger zone. The receiver transfers the image
data from the detection zone to the special module PSSu K F FAU. If an object encroaches
into the detection zone, the two outputs on the PSSu K F FAU shut down and the LED on
the receiver goes out. A stop of the press stroke is initiated.
On the productive version, safety functions must be implemented in the PAS4000 user pro-
gram in order to safeguard dynamic muting. Certified Pilz blocks are available for this the
PAS4000 Library.
