Descriptions of operating modes
Symbol Operating mode
Adaptive control active
When the PositionMaster EDP300 positioner is
operated in "Adaptive Mode", the control
parameters are automatically optimized to the
operating conditions in small increments. This is
particularly useful if valves and fittings could not be
operated with reference conditions while the
Autoadjust function was in progress.
The self-optimization process in "Adaptive Mode" is
subject to several factors, meaning that incorrect
adjustments could be made over an extended
period. It is recommended that this operating mode
is only activated over several hours and that the
"Fixed control" operating mode is selected following
this.
Fixed control
In contrast to the "Adaptive control" operating
mode, the control parameters are not automatically
adjusted.
