} Automatic start
– Position monitoring is started when a rising edge has been detected at the start input.
– Position monitoring is started when the parameter set has been switched over and
position monitoring is used in the current parameter set.
– Position monitoring is restarted when the limit value has been exceeded and a rising
edge has been detected at the start input.
– Active position monitoring is not started again by another rising edge at the start in-
put.
– Active position monitoring is restarted if another parameter set is selected, which also
uses position monitoring. This also applies if position monitoring is used in a different
switch function.
– Active position monitoring is deactivated if another parameter set is selected, which
does not use this position monitoring.

monitoring.
} In the event of an open circuit, position monitoring is automatically deactivated
