Position
Position monitoring is activated via a rising edge at the start input. The current position is
adopted as a reference position in the middle of the position window (configured window
width) and the assigned output is switched on.
The output will stay switched on provided the current position is within the position window.

If the position moves outside the configured range, position monitoring is reset and the as-
signed outputs are switched off. Position monitoring can be restarted via a rising edge at
the start input
A max. of 4 positions can be configured to be monitored simultaneously.
Please note:
} Active position monitoring is not started again by another rising edge at the start input.
} Active position monitoring continues unchanged even if a different parameter set is se-
lected, which also uses position monitoring. This also applies if position monitoring is
used in a different switch function.
} Active position monitoring is reset if another parameter set is selected, which does not
use position monitoring.
} Position monitoring cannot be used if proximity switches are employed.
