Example 2: Pipe bending machine
The LSI system is configured as follows:
– One PLS sensor connected
– Two protective fields (simultaneous) and one warning field
defined
– Two OSSD outputs and one warning field output configured
– Three monitoring cases configured, activated via the binary
inputs
– Any order of monitoring cases
Note on the circuit diagram:
Use only relays with positively-driven contacts.
The protective elements switched in parallel with the contactors
are for arc suppression.
1) Output circuits. These contacts are to be incorporated into
the controller such that, when the output circuit is open, the
hazardous state is controlled.
In categories 3 and 4 to EN 954-1, they must be
incorporated on two channels (x, y paths).
