5. During the automatic initialization, adjust the booster bypass using the adjustment screw on
the booster. For single-acting actuators, there is one adjustment screw; there are two
adjustment screws for double-acting actuators. Observe the description of your booster.
If 'oCAY' is shown on the display, the overshoot is less than 3%.
Adjustment of the booster is sufficient. If you do not achieve the message 'oCAY' (<3%
overshoot), try instead to achieve as small a value as possible. Observe the travel time in
the process.
6. Press the
starting with determination of the travel times. The following figure schematically shows the
RUN 3 sequence for the booster.
7. 'FINISH' is shown on the display when the initialization has been completed.
If the process value on the display does not remain stable or if a constant manipulated variable
cannot be achieved for a constant setpoint, further optimization of the controller data is
necessary. This is described in section Optimization of controller data (Page 104).
