Locking all operational controls via the IN input (Pin 5)
A static HIGH signal (
≥
20ms) at the IN input (Pin 5)
locks all operational controls on the sensor if required,
such that no manual operation is possible (e.g., protec
-
tion from erroneous operation or manipulation).
If the input is not connected or if a static LOW signal is
being applied, all operational controls are unlocked and
can be operated freely.
