Pulse pick-ups (sensors)
Observe the current consumption of the sensors.
Supply the sensors externally if the current consumption exceeds the
currentratingoftheterminalsS33andS44(→11Technicaldata).
7.5 Feedback contact
► Connect the feedback contact to input A2 (Y4-Y5).
► Observethecharacteristicdataoftheinput(→11Technicaldata).
If the monitoring function is not required, the terminals Y4-Y5 can be
