Function description
The motion sequence of the press is monitored by the automation system PSS 4000. In the
PSS 4000 user program safety functions must be implemented to safeguard the dynamic
muting of PSENvip. (see chapter 10 "System Connections").
The receiver receives the parallel light beam bundle generated by the transmitter. The light
beam bundle is enclosed by the illuminated target area. The lens on the receiver only de-
tects light that runs parallel to the optical axis. This guarantees stability against diffused
light.
The receiver monitors and evaluates the detection zone between the transmitter and re-
ceiver. The protected field is the cross section of the detection zone. It consists of several
segments.
