5.1.8 Description of operating modes
SYMBOL
OPERATING MODE
Adaptive control active
When the SP8-10 positioner is operated in ‘Adaptive Mode’, the control parameters
are automatically optimized to the operating conditions in small incremwents. This
is especially helpful if valves and fittings could not be operated with reference
conditions while the Auto Adjust function was in progress.
The long-term stability of the adaptive operating mode results more from the system
structure than from the changing behavior of the system, meaning that if a stable,
adaptive operating mode can be obtained over several days of control variations in
the system application with positioner, actuator, valve and changes in behavior, we
can assume stable operation in the application mentioned above.
If that is not the case, the ‘Non-adaptive control’ option should be selected.
Fixed control
In contrast to the ‘Adaptive control’ operating mode, the control parameters are not
automatically adjusted.
Manual set point, adaptive contro
l
The valve is adjusted manually within the stroke range using the UP or DOWN
direction buttons.
1.
Press and hold the relevant operating button for the desired direction
2.
Additionally, press
LEFT
if the device is to be switched to high-speed mode.
Manual set point, fixed control
The valve is adjusted manually within the stroke range using the UP or DOWN
direction buttons.
1.
Press and hold the relevant operating button for the desired direction
2.
Additionally, press
LEFT
if the device is to be switched to high-speed mode.
Moving the actuator manually
The valve is adjusted manually within the valve range using the UP or DOWN
direction buttons. The position indicator shows the position in angular degrees for
the purpose of checking the mounting conditions.
1.
Press and hold the relevant operating button for the desired direction
2.
Additionally, press
LEFT
if the device is to be switched to high-speed mode.
