OPERATING THE PROCESS CONTROLLER
The setpoint step for parameter optimization must always be entered via the operating
keypad. This also applies when, on configuration, the function
P.CONTRL / P.CO SETP /
SETP EXT
(setpoint setting via analog input) is specified. In this case, the external setpoint
setting is reactivated only after completion of process tune.
NOTE
Self-optimization of the process controller now runs automatically. The display shows a rotating bar and
the message
P.TUNE
. After completion of process tune, the device is in the
AUTO
mode. The process
controller works from this point on with the optimized PID parameters and controls to the current,
internal or external setpoint
SP.
To execute a new optimization cycle, repeat

.
The Process Tune in the conrol menu of the TOP Control Continuous remains active, so that
the process control takes place with the Set-value-Modulation (Filer) for the reduction of
unwanted, non-linear effects. If the control will be carried out without the Set-value-Modulator,
the process tune in the control menu must be deactivated:
P.CONTRL
/
P.CO TUNE
/
P. TUN
D´ACT
To stop the self-optimization, press both arrow keys at the same time and select
P.TUN BRK
.
