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-
mand can be used to move out of the limit switch zone.
The limit switch must not be overrun. The signal must be applied continu-
ously (no pulse evaluation).
