Intended use
EXPERTplus is a diagnostic rmware integrated into the positioner which allows the predic-
tive, status-oriented maintenance of valves with pneumatic actuators.
EXPERTplus records the valve condition while the process is running (in automatic mode) and
generates messages on the required maintenance work. In addition, numerous tests can be
performed in manual mode to pinpoint emerging faults.
The diagnostic functions of EXPERTplus are completely integrated into the positioner. Diag-
nostic data are compiled, saved and analyzed in the positioner itself. Classied status mes-
sages on the state of the valve are generated from the analysis.
Reasonably foreseeable misuse
While the tests are being performed, the valve does not follow the set point. Instead, it is
moved according to the test specications. Therefore, the tests can only be started when the
conditions in the plant allow it.
Qualications of operating personnel
The devices are to be congured and set by trained and experienced personnel only. Ac-
cording to these operating instructions, trained personnel refers to individuals who are able
to judge the work they are assigned to and recognize possible hazards due to their special-
ized training, their knowledge and experience as well as their knowledge of the applicable
standards.
Personal protective equipment
No personal protective equipment is required.
Revisions and other modications
