6 Operating elements
The linear position transducer does not have any operating controls. User intervention
is therefore neither possible nor necessary.
7 Commissioning
The user manual instructions must be followed. The geometry and cleanliness of the
installation space, the sound condition of the sealing surfaces and sealing elements,
and the electrical connection are particularly crucial.
8 Interval between repeat testing
The operating life of the position transducer is defined as 20 years. The reliability of
the electrical, electronic and mechanical components is such that no repeat testing is
required during the unit's operating life.
