5.8.5 Dual-channel sensor, monitored
All cross fault connections and connections to DC 24 V and DC 0 V can be detected
when two independent pulse signals are used on a homogeneous sensor. Use only NC
contacts for safety applications.
Note that when connecting a diversified sensor (see above figure), only the NO contact
is monitored regularly. As with the homogeneous sensor, all types of faults are detected
in the supply line.
