Supports self-tuning of the working range on the valve.
Control loop "self-tuning" through the PID function block
is not supported.
The positioner is delivered in an unadjusted state.
The standard autoadjustment function has to be run to
adapt the working range and control parameters.
Otherwise the transducer block will remain in "Out of
service" mode.
Self-diagnostic of positioner hardware and software.
Basic valve diagnostics incl. extended alarm handling
