Description of operating modes

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
especially helpful if valves and fittings could not be
operated with reference conditions while the Auto
Adjust function was in progress.
The self-optimization process in "Adaptive Mode" is
affected by several factors that can result in
incorrect adjustments in the long term. 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.
Manual setpoint, adaptive control
The valve is adjusted manually within the stroke
range using the
or
direction buttons.
1.
Press and hold the relevant operating button for
the desired direction.
2.
Additionally, press
if the device is to be
switched to high-speed mode.
CAUTION – Risk of crushing
Configured stroke limit positions
and stroke times are not effective in
manual mode. When the actuator
moves, there is a risk of crushing.
You must make sure that no-one is
present within the actuator's
working range.
