Controlling operation with automatic adaptation of the control parameters When the P1.0CTRL_ADP 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. Since self-optimization in "Adaptive Mode" is subject to several factors during operation and mismatches
could result over a longer period, we recommend that this operating mode only be activated over several hours and be followed by the
mode P1.1 CTRL_FIX.
The valve position is indicated as a percentage of the operating range (from 0 ... 100%).
2.5 Menu levels
The positioner has two operating levels:
Operating level
On the operating level the positioner operates in one of four possible operating modes (two
for automatic control and two for manual mode). Parameters cannot be changed or saved
on this level.
Configuration level
On this level most of the parameters of the positioner can be changed locally. The PC is
required to change the limit values for the movement counter, the travel counter, and the
user-defined characteristic curve. On the configuration level the active operating mode is
deactivated. The I/P module is in neutral position. The control operation is inactive.
NOTE
Property damage
During external configuration via a PC, the positioner no longer responds to the setpoint current. This may
lead to process failures. Prior to external configuration, always move the actuator to the safety position and
activate manual adjustment.
