8.5.8. Setting range: limit
Travel can be limited in directions OPEN and/or CLOSE.
This prevents end position(s) OPEN and/or CLOSED from being approached in
modulating duty. The actuator stops when reaching the set limit value.
For OPEN - CLOSE control (LOCAL or REMOTE OPEN-CLOSE operation mode),
this limitation is not active.The valve can then be run into the end positions either
via the local controls or from remote.
