Function description
Basic function
The safety light grid consists of a transmitter and a receiver.
Their shape and design
}
protect the transmitter and receiver from external damage
}
protect the safety light grid from malfunctions caused by vibration (see
Technical de-
tails, environmental data section [
43]
).
The protected area is covered by infrared light beams, which are emitted from the transmit-
ter to the receiver. The protected field thus produced is able to detect an opaque object.
The control and monitoring of the transmitted and received infrared rays is performed by
microprocessors.
The output signal switching devices (OSSDs) switch to the OFF state when one of the fol-
lowing conditions is met:
}
one or more light beams are interrupted by an object, a body part, or an opaque object
that is at least as large as the resolution (24 mm) covered by the safety light grid,
}
an error is detected by one of the OSSDs,
