Limit switch evaluation
Figure 4.9 Example of a limit switch evaluation
Figure 4.10 Limit switch evaluation of S4 and S3
Example: Limit switch right resets Start-Clockwise. Resetting of Start-
Clockwise is not evaluated. The Start-Anti-Clockwise com-
mandcanbeusedtomoveoutofthelimitswitchzone.
Note: Overriding the limit switches is not permitted! For this reason,
a mechanical override guard must be provided. The limit swit-
ches are evaluated on the basis of evaluation of static signals
and not based on signal edges, so an override is not evalua-
ted.
